Scripts

The following are the script files used in this installation:

This page shows the example to install and configure Teamwork Cloud (TWCloud) 18.5 Standard Edition on Centos 7.x, deployed on a single server. It also shows the configuration in which both the Teamwork Cloud node as well as the underlying Cassandra node are installed on the same server.

TWCloud installation and configuration on Centos 7.x on a single server.

Minimum server system requirements:

  • 8 Processor Cores - i.e. Quad Core Hyper-threaded CPU (such as Intel E3-1230 or faster).
  • 32 GB RAM (Motherboard with an ECC RAM is always preferred on any critical database server).
  • Linux (RedHat/CentOS 7), 64 bit.  Scripts need to be modified slightly for Centos 6.6 - 6.9 due to different system daemon and firewall configuration.

Please read the article for additional server recommendations for capacity and performance from the following link:

https://docs.datastax.com/en/cassandra/2.2/cassandra/planning/planPlanningHardware.html

If you use SATA drives and not SSD's, we recommend using a caching controller with BBU, configured for write back. In this configuration (single node Cassandra), we recommend using RAID - the aforementioned link is referring to multi-node Cassandra deployments where native Cassandra replication is in place, which is not the case in this single node instance.

In order to install a full working environment, the following is required:

  • Oracle Java (Java Hotspot) 1.8.0_162
  • A FlexNet License Server
  • Cassandra 3.11.2
  • Teamwork Cloud

Preparing the operating system

Partitioning the drives

In order to achieve adequate performance, separate partitions must be created, ideally on separate drives, to avoid i/o contention. We recommend 3 separate block devices (disks). The first block device will contain the operating system as well as a mount for the programs (/opt/local). The second block device (preferably SSD) will contain a mount point at /data - this is the device which must have high storage capacity for all of the data. The third block device will contain a mount point at /logs - this device should preferably be SSD, but does not need to be of high capacity, since it will only store the commit logs, which are by default limited to 8GB (if using SSD, this can be a partition on the same block device as the data partition). All partitions should be formatted using the XFS file system, and there must not be a swap partition.

The following is an example of the contents of  /etc/fstab after partitioning, where the partitions were created using
 LVM:

fstab
#
# /etc/fstab
# Created by anaconda on Tue May  2 16:31:05 2017
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/cl_twccentos7-root /                       xfs     defaults        0 0
/dev/mapper/cl_twccentos7-data /data                   xfs     defaults        0 0
/dev/mapper/cl_twccentos7-logs /logs                   xfs     defaults        0 0
/dev/mapper/cl_twccentos7-opt_local /opt/local         xfs     defaults        0 0


  • Disk 1 will contain the following partitions:  /opt/local (40GB) and / (rest of the drive capacity)
  • Disk 2 (the disk with the highest capacity) will contain the /data partition
  • Disk 3 will contain the /logs partition (10 GB)

The aforementioned partitioning scheme is an example. Internal security protocols in your organization may dictate that other directories not be located in the main partition. During the installation, all applications will be installed in /opt/local. Cassandra will install by default in /var/lib. Application logs will be written to /home/twcloud.

Installing Oracle Java

From the Java version list, please check that the recommended Oracle JVM version is compatible with the TWC version you are using.  It is not recommended to use OpenJDK. In order to consolidate all of the installed applications in a single location, we will be installing under /opt/local/java. To facilitate deployment, you may deploy using the associated script (install_java_162.sh).  Oracle no longer allows direct download of their JDK, so it must be downloaded offline and placed in the same location as the install scripts.  The installation script extracts it into the proper location, invokes the alternatives command to point the system to this instance (you may need to select it when prompted), and creates entries in /etc/environment. Upon completing the installation, issue the following command:

java -version


You should receive output such as the following:

java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b13, mixed mode)


If properly installed, you will see Java identified as Java HotSpot(TM)

Installing the FlexNet server (lmadmin)

A FlexNet license server is required for TWCloud to operate.  It can be installed on the same system, or on a separate machine. The automated deployment script (install_flex_centos7.sh) downloads all required components, deploys the server, creates the systemctl service entry to control it, and creates the necessary firewalld rules to allow the required traffic. The firewall rules are created for both the internal and public zones, and the script may require modification depending on which zone the interface is located. Additionally, if firewalld is not running when the installation script is executed, the rules will not be created. The script creates a user, lmadmin, which runs the lmadmin service. The FlexNet server requires the Redhat LSB core files as well as the ld-linux library in order to execute. The script is configured for Centos 7, but can be modified for a different version.  In order to identify which LSB Core library is required, the following command can be issued:  

sudo yum provides /lib/ld-lsb.so.3

The application should be installed in /opt/local/FNPLicenseServerManager (the installer's default location is /opt/FNPLicenseServerManager - so make sure that you change the location when prompted). All other default values presented by the installer should be accepted.

  • After the lmadmin server has been installed it can be started by issuing the command:
    sudo systemctl start lmadmin


  • To check if the service is running, issue the following command
    sudo systemctl status lmadmin


  • If the service failed to start, it is often because the built-in web server cannot resolve the host name.  To check if this is the case issue the following commands:
    cd /opt/local/FNPLicenseServerManager/logs
    tail web.log

You will see output similar to the following:

[Tue May 02 18:43:27 2017] [alert] (EAI 2)Name or service not known:
mod_unique_id: unable to find IPv4 address of "yourhostname"
Configuration Failed

Where yourhostname is the name of the host.  IF this is the case, you will need to edit the /etc/hosts file and add an entry so the web server can resolve the host. The line will be in a format similar to the following:

192.168.130.10  yourhostname

Installing Apache Cassandra 3.11.2

The deployment script for Cassandra removes Datastax Community Edition 2.2.x as well as OpsCenter and the Datastax Agent (which are not compatible with Cassandra 3.x), downloads and installs Cassandra the Cassandra tools from the Apache Software Foundation repository, and creates the necessary firewalld rules to allow proper operation both for a single node or a cluster installation.  To install, execute the installation script (install_cassandra_3_11_centos7.sh).

sudo \cp -fR ./cassandra.yaml.template /etc/cassandra/default.conf/cassandra.yaml 


Upon completion of the installation, issue the following command to ensure that Cassandra starts automatically upon system reboot. 

     chkconfig --add cassandra


Now, proceed to edit /etc/cassandra/default.conf/cassandra.yaml

      sudo nano /etc/cassandra/default.conf/cassandra.yaml

Note:  The script above makes all of the changes to the configuration files stated below.  However, please verify that all of them have been set.  The first items we will be editing relate to the IP address of the Cassandra node and communications settings.  In our diagram above, this IP address is 192.168.130.10.  You will need to search for 3 keys in the configuration file and modify them accordingly.  The seeds parameter is a comma-delimited list containing all of the seeds in the Cassandra cluster.  Since our cluster consists of only the single node, it contains only one entry - our IP address.  The other 2 parameters contain the IP address on which Cassandra listens for connections and the IP address to broadcast to other Cassandra nodes in the cluster.  The broadcast_rpc_address may be commented out using a # character.  If so, remove the "#" and make sure there are no leading spaces.

Additionally, we need to set rpc_address to 0.0.0.0 (meaning, it will listen to rpc requests on all interfaces), and start_rpc to true (so it will process rpc requests).

  • seeds: "192.168.130.10"
  • listen_address: 192.168.130.10
  • broadcast_rpc_address: 192.168.130.10
  • rpc_address: 0.0.0.0
  • start_rpc: true

The next set of parameters control thresholds to ensure that the data being sent is processed properly.

  • thrift_framed_transport_size_in_mb: 100
  • commitlog_segment_size_in_mb: 192
  • read_request_timeout_in_ms: 1800000
  • range_request_timeout_in_ms: 1800000
  • write_request_timeout_in_ms: 1800000
  • cas_contention_timeout_in_ms: 1000
  • truncate_request_timeout_in_ms: 1800000
  • request_timeout_in_ms: 1800000
  • batch_size_warn_threshold_in_kb: 3000
  • batch_size_fail_threshold_in_kb: 5000

If you have installed your commit log in its own partition, the default commit log size will be the lesser of ¼ of the partition size or 8GB.  In order to ensure that the recommended 8GB is used, you must uncomment the commitlog_total_space_in_mb, such that it will show as below. However, if you are uncommenting this value, please ensure that the partition has enough space to accommodate an 8GB commit log.

  • commitlog_total_space_in_mb: 8192  

The next step is to point the data to the new locations. There are 4 entries which will be modified: data_file_directoriescommitlog_directory, hints_directory, and saved_caches_directory.  Search for these keys and edit them as follows:

  • data_file_directories:
    - /data/data
  • commitlog_directory: /logs/commitlog
  • hints_directory: /data/hints
  • saved_caches_directory: /data/saved_caches


After you have made these changes, save the cassandra.yaml file.  Now, start the related services, as follows:

sudo service cassandra start

Wait about 30 seconds for the initial installation of Cassandra to complete its bootdtrapping process, and proceed to check if Cassandra is running.  To do this, issue the following command:

      nodetool status


If the service is running, you will receive output such as below:

Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens   Owns (effective)  Host ID                               Rack
UN  127.0.0.1  128.4 KB   256      100.0%            ea3f99eb-c4ad-4d13-95a1-80aec71b750f  rack1

If the service is fully operational, the first 2 characters on the last line will state "UN", indicating the node's status is Up, and its state is Normal.

When you are installing TWCloud


  1. Press ENTER until the licensing agreement is accepted.
  2. Configure the machine IP - enter the local IP address of the machine (i.e. 192.168.130.10).
  3. Configure the cluster seed node IP - enter the local IP address of the machine (i.e. 19.168.130.10). 
  4. Configure the TWCloud service owner - enter twcloud
  5. Configure JAVA_HOME - it should display  /opt/local/java/jdk1.8.0_162 - accept this default.
  6. Choose Install Folder - the default is set to /home/twcloud/TeamworkCloudDo not accept the default, and instead enter /opt/local/TeamworkCloud

Post-Install Configuration

The installer has created the preliminary configuration of TWCloud. There are a few more changes which we must make to the various configurations files in order for TWCloud to be fully functional.

  1. /opt/local/TeamworkCloud/configuration/application.conf - configuration file for the TWCloud service.

If TWCloud is installed behind a proxy or firewall with NAT, upon the initial connection the MagicDraw client must know the external IP address to which it must connect.  Search for server-broadcast-host, and enter the public IP address instead of the local IP address.

We now need to point TWCloud to the Cassandra database.  Search for seeds =, which is located in the connection section. Edit the value inside the quotes to point to the listen_address you set in cassandra.yaml (i.e. seeds = ["192.168.130.10"])

A default password has been entered in the configuration file for its communication with the authorization server.  It is recommended that it be changed from default.  Search for CHANGE_ME, which is associated with the field pswd, and replace it with a password of your choosing.

At the bottom of the configuration file there is a section covering the authentication server (esi.auth). Make sure that the server property is pointing to the local IP address of the machine.

# Authentication Server address
esi.auth {
                # Authentication Server protocol, IP address and port
                # InetAddress.getLocalHost.getHostAddress is used if server is left empty
                protocol = "https"
                server = "192.168.130.10"
                port = "8555"
 
                # URL to Authentication Server REST API, which returns server configuration.
                config {
                        path = "/authentication/.well-known/openid-configuration"
                }
 
                # URL to Authentication Server login page.
                login {
                        path = "/authentication"
                }
}

2.  /opt/local/TeamworkCloud/AuthServer/config/authserver.properties - configuration file for Authorization service.

  • server.public.host=public IP address (same as server-broadcast-host in application.conf). If you are accessing the server via a FQDN, use it instead of the IP address.
  • twc.server.host=local IP address.
  • If you changed the pswd field in /opt/local/TeamworkCloud/configuration/application.conf from the default, you must modify this file accordingly. Search for authentication.client.secret. Remove the leading # (to uncomment the directive), and replace the CHANGE_ME value with the same value as that in application.conf.
  • If you are accessing the server by FQDN, you must edit the property authentication.redirect.uri.whitelist by adding an entry to whitelist the FQDN.  For example: authentication.redirect.uri.whitelist=https://192.168.130.10:8111/twcloud_admin/,https://FQDN:8111/twcloud_admin/,https://md_redirect

Log Files

Teamwork Cloud executes under the twcloud user, and by default will store log files under this user's profile (/home/twcloud).  There are 2 configuration files which control the location of these log files:

/opt/local/TeamworkCloud/configuration/logback.xml

In this file, there are settings for 2 log files which must be edited.

<appender name="SERVER-FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
                <file>${user.home}/.twcloud/18.5 sp4/server.log</file>
                <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
                        <fileNamePattern>${user.home}/.twcloud/18.5 sp4/server.%i.log.zip</fileNamePattern>
                        <minIndex>1</minIndex>
                        <maxIndex>1000</maxIndex>
                </rollingPolicy>
 
                <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
                        <maxFileSize>20MB</maxFileSize>
                </triggeringPolicy>
                <encoder>
                  <pattern>%-5.5level %date{YYYY-MM-dd HH:mm:ss.SSS} %message [%logger{200}, %thread{10}]%n</pattern>
                </encoder>
        </appender>
 
        <appender name="SECURITY-FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
                <file>${user.home}/.twcloud/18.5 sp4/security.log</file>
                <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- daily rollover -->
                <fileNamePattern>${user.home}/.twcloud/18.5 sp4/security.%d{yyyy-MM-dd}.log</fileNamePattern>
 
                <!-- keep 365 days' worth of history -->
                <!-- maxHistory>365</maxHistory -->
        </rollingPolicy>
                <encoder>
                  <pattern>%-5.5level %date{YYYY-MM-dd HH:mm:ss.SSS} %message [%logger{200}, %thread{10}]%n</pattern>
                </encoder>
        </appender>


In each section, there are 2 settings which must be modified:  file and fileNamePattern. The first setting (file) controls the absolute path to the latest log file.  The second setting (fileNamePattern) controls the naming convention for the archiving of the log files.  In most cases, it will suffice to replace the ${user.home} token with a different location, but you must ensure that the twcloud user has ownership of the target directories.

/opt/local/TeamworkCloud/Authserver/config/logback-spring.xml

This file contains one section which must be modified.

  <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
                <file>${user.home}/.authserver/18.5.SP4/authserver.log</file>
                <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
                        <fileNamePattern>${user.home}/.authserver/18.5.SP4/authserver.%i.log.zip</fileNamePattern>
                        <minIndex>1</minIndex>
                        <maxIndex>10</maxIndex>
                </rollingPolicy>
 
                <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
                        <maxFileSize>30MB</maxFileSize>
                </triggeringPolicy>
                <encoder>
                  <pattern>%-5.5level %date{YYYY-MM-dd HH:mm:ss.SSS} %message [%logger{0}, %thread{10}]%n</pattern>
                </encoder>
        </appender>

The same changes and permissions apply to the changes to this file as to those for /opt/local/TeamworkCloud/configuration/logback.xml.

Frequently Asked Questions

I am receiving an error when trying to access the Teamwork Cloud Admin Console, before being prompted for user credentials.

This is usually caused by the authentication server not running, and depending on the browser may include a page beginning with:

{ "issystemerror": true, "data": "Class: org.springframework.web.client.ResourceAccessException
  • To check if the authentication server is running, issue the command sudo service authserver status.
  • If it states it is stopped, start it via the command sudo service authserver start.
  • If it is running and you are receiving a browser window requesting you contact the system administrator, the cause for this may lie with the authentication.redirect.uri.whitelist field in authserver.properties.
  • If you are accessing via the FQDN, and the UEL is showing the FQDN of the machine, please add it in the form of https://FQDN:8111/twcloud_admin/ and restart the authserver service via the command sudo service authserver restart

I am unable to access the Teamwork Cloud Admin Console.

First, let's make sure that the service is running.  This is done via the command sudo service twcloud-svc status. Also, make sure that the authserver service is running, via the command sudo service authserver status.  If the services are running, the result of the command will be:

Running [PID]

Where PID is a number representing the process ID of the service. If the services are running, let's ensure that they are listening on the expected ports.  This is done by issuing the following commands:

netstat -anp | grep tcp | grep 8111 | grep LISTENand
netstat -anp | grep tcp | grep 8555 | grep LISTEN
The result should be something along the lines of

 [root@twccentos7 ~]# netstat -anp | grep tcp | grep 8111 | grep LISTEN
 tcp6       0      0 :::8111                 :::*                    LISTEN      28294/java          
 [root@twccentos7 ~]# netstat -anp | grep tcp | grep 8555 | grep LISTEN
 tcp6       0      0 :::8555                 :::*                    LISTEN      28466/java   


If you get a command not found message when executing netstat, this means it is not installed on your computer. To install it, execute the following command

yum install net-tools

and then retry once the package has been installed.

If the ports are listening, then the issue relates to traffic not being allowed into the computer on these ports. This may be caused either by the Linux firewall, or by an external firewall.  To temporarily turn off the Linux firewall, issue the following command:

sudo systemctl stop firewalld

If you can connect when the firewall is stopped, then you must check the firewall rules to ensure you are allowing traffic on both ports 8111 and 8555.  To restart the Linux firewall issue the following command:

sudo systemctl start firewalld

If you were unable to connect, please contact your IT system administrators to ensure that they are not blocking traffic on these ports to the computer.
