This page shows the example page shows how to install and configure Teamwork Cloud (TWCloud) 19.0 Standard Edition on Centos 7.x, deployed on a single server. It also shows provides the configuration in which both for installing 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:
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 are required.
Oracle Java (Java Hotspot) 1.8.0_202
A FlexNet License Server
Cassandra 3.11.x
Teamwork Cloud
Preparing the operating system
Partitioning the drives
Prior to installing Cassandra, it is important to understand how Cassandra utilizes disk space in order to properly configure the host server.
Disk space depends on usage, so it's important to understand the mechanism. The database writes data to disk when appending data to the commitlog for durability and when flushing memtables to SSTable data files for persistent storage. The commit log has a different access pattern (read/writes ratio) than the pattern for accessing data from SSTables. This is more important for spinning disks than for SSDs.
SSTables are periodically compacted. Compaction improves performance by merging and rewriting data and discarding old data. However, depending on the type of compaction and size of the compactions, during compaction disk utilization and data directory volume temporarily increases. For this reason, be sure to leave an adequate amount of free disk space available on a node.
Cassandra data and commit logs should not, under any circumstances, be placed on the drive where the operating system is installed. Ideally, a server would have 3-4 drives or partitions. The root partition, /, the OS partition, can be used as the target for the application. A /data partition should have adequate amounts of storage to accommodate your data. A /logs partition would hold your commit logs (and unless SSD, should be on a different physical disk than the data partition), and a /backup partition would be allocated for backups.
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 /backup partition can be a mount on a shared storage device, and shoud not be on the same physical drive as the /data partition. The following is an example of the contents of /etc/fstab after partitioning, where the partitions were created using
Recommended system requirements
System requirements are dictated by the intended deployment, taking into account the overall load which the environment will experience:
Number of concurrent users
Level of activity (commits) per day
Overall number and size of the projects stored in Teamwork Cloud.
From a hardware perspective, the database (Cassandra) can be located on the same server as Teamwork Cloud, or separately into its own server. Storage requirements apply only to the node where the database is located.
Ideally, the node hosting Cassandra should be a physical node, since virtualization will introduce performance degradation. Nodes running Cassandra should have DAS SSD drives (direct-attached). The best performance will be achieved using NVMe drives. Presently, there are hardware limitations on the size of the NVMe drives as well as the number of NVMe drives that can be installed on a single machine. Therefore, if the expected number and size of projects are significant, SAS SSD backed by a high-speed caching controller may be a more suitable choice. For ease of maintenance and reduction of risk, we recommend that the volumes reside on RAID-1 or RAID-10. If RAID is not used, the failure of a drive will result in a downed node, impacting the enterprise. By opting to deploy on RAID volumes, a drive failure will not affect the application and will allow the replacement of a drive with zero downtime.
Nodes hosting Teamwork Cloud nodes can be virtualized without any issues, provided the host is not oversubscribed on its resources.
Nodes containing both Teamwork Cloud and Cassandra
96 -128 GB ECC RAM
>=16 processor threads (such as E5-1660)
>1TB SSD DAS storage
Nodes containing only Cassandra
48 - 64 GB ECC RAM
>=8 processor threads (such as E5-1620)
>1TB SSD DAS storage
Nodes containing only Teamwork Cloud
48 - 64 GB ECC RAM
>=8 processor threads (such as E5-1620)
>250GB storage

Multi-Node Clusters
Recommended minimum sizing stated above applies to each node in a multi-node cluster.
Warning

SAN Storage
SAN Storage should not be used on Cassandra nodes for data or commitlog volumes. This will result in severe performance degradation. There is absolutely no amount of SAN tuning and OS tuning which will mitigate this.

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 - as a minimum, we recommend 250GB. Due to the way compactions are handled by Cassandra, in a worst-case scenario up to 50% of headroom may be needed.
Disk 3 will contain the /logs partition (at least 10 GB).
You should also create an additional mount for backups. Unlike the data and commit log partitions, which should be on SSD storage, this mount can be of any type (including centralized storage such as a SAN or NAS). It should have at least the same capacity as the /data partition.
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 (Option 1)
From the Java version list, please check that the recommended Oracle JVM version is compatible with the TWCloud version you are using. In order to consolidate all of the installed applications in a single location, we will be installing them under /opt/local/java. To facilitate deployment, you may deploy using the associated script (install_java_202.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 alternative 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:

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:

To install, execute the installation script (install_cassandra_3_11_centos7.sh).
The script above makes all of the changes to the configuration files stated below.
However
However, please verify that all of them have been made.
The first items we will be editing relate to the IP address of the Cassandra node and communications communication settings.In In our diagram above, this IP address is is 192.168.130.10.You You will need to search for 3 keys in the configuration file and modify them accordingly.The The seeds parameter is a comma-delimited list containing all of the seeds in the Cassandra cluster.Since Since our cluster consists of only the a single node, it contains only one entry - our IP address.The 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

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_directories, commitlog_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
Now, 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

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.
Tuning Linux for Cassandra Performance
There are multiple tunings which can be performed on Linux to improve the performance of Cassandra. The first step is to configure the TCP settings by adding the following tuning parameters to /etc/sysctl.conf file:
net.ipv4.tcp_keepalive_time=60
net.ipv4.tcp_keepalive_probes=3
net.ipv4.tcp_keepalive_intvl=10
net.core.rmem_max=16777216
net.core.wmem_max=16777216
net.core.rmem_default=16777216
net.core.wmem_default=16777216
net.core.optmem_max=40960
net.core.somaxconn=4096
net.ipv4.tcp_rmem=4096 87380 16777216
net.ipv4.tcp_wmem=4096 65536 16777216
vm.max_map_count=1048575
To apply the setting without requiring a reboot issue the command:
# sysctl -p
For a full list of steps to take to tune Linux, go to:
The deployment script for TWCloud (install_twc19sp1_centos7.sh) creates a twcloud user, under which the service will run, and downloads all of the necessary files and executes the installer.

When you are installing TWCloud
Press ENTER until you will be asked to configure the machine IP.
Configure the machine IP - enter the local IP address of the machine (e.g. 192.168.130.10).
Configure the cluster seed node IP - enter the local IP address of the machine (e.g. 192.168.130.10).
Configure the TWCloud service owner - enter twcloud.
Configure JAVA_HOME - if you are using Oracle Java, using our installation script, you will be prompted with /opt/local/java/jdk1.8.0_202 - accept this default. If you are using OpenJDK from the RPM packages, use /etc/alternatives/jre_1.8.0, so that subsequent updates via yum will not affect the installation.
Choose Install Folder - /opt/local/TeamworkCloud.
Next, TWCloud's Pre-Installation Summary will appear. It should look as follows:

Note
Anywhere where 192.168.130.10 is displayed, you must replace it with the IP address of your machine.
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.
/opt/local/TeamworkCloud/configuration/application.conf - the 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.
2. /opt/local/TeamworkCloud/AuthServer/config/authserver.properties - the 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.

cassandra.contactPoints=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.
3./opt/local/TeamworkCloud/WebAppPlatform/shared/conf/webappplatform.properties- the configuration file for TWC Admin Console.
twc.admin.username - Set it to the username of a local account with Administrator privileges (default is Administrator).
twc.admin.password - Set it to the password corresponding to the Administrator user (default is Administrator).
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 and replace the CHANGE_ME value with the same value as that in application.conf.

Log Files
TWCloud executes under the TWCloud user, and by default will store log files under this user's profile (/home/twcloud). There are 3 configuration files that control the location of these log files:
/opt/local/TeamworkCloud/WebAppPlatform/shared/conf/logback.xml controls the location of the WebAppPlatform log files.
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.
In each section, there are 2 settings that 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.

This file contains one section which must be modified.
A: This error is typically caused by incorrect credentials for the authentication of webapp. This is accompanied by recurring error messages in web-app.log.
2019-10-12 14:49:14,625 [main] INFO com.nomagic.webappplatform.internal.version.TWCVersionValidator - Waiting for TWC/AuthServer to start, 120 of 120 2019-10-12 14:49:14,626 [main] ERROR com.nomagic.webappplatform.internal.version.TWCVersionValidator - Exception occurred during version checking
Verify that the credentials are correct in webappplatform.properties
Q: When Accessing the Teamwork Cloud Admin Console (webapp), I get a system error when redirected to the Authserver login screen
Image Added
A: This error is typically caused by an omission of the referring URL in the authentication server's whitelist, authentication.redirect.uri.whitelist, located in authserver.properties.
You will see a corresponding error in authserver.log.
Update the whitelist to include the referring URL. A common cause is accessing WebApp via a server name of FQDN when the whitelist only contains entries for the IP address.
Q: After entering my credentials in the Authserver login screen, I am not logged in, no error is displayed, and I am presented once again with the login screen
Image Added
A: This error is typically caused by a mismatch in the client secret entries - authentication.client.secret located in authserver.properties and webappplatform.properties, and "pswd" in application.conf.
You will see a corresponding error in authserver.log
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:
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 URL is showing the FQDN of the machine, please add it in the form of https://FQDN:8443/webapp/ and restart the authserver service via the command sudo service authserver restart.
