1. Install OpenJDK 11, if needed. If you used the Apache Cassandra installation script on the same server, then Java 11 is already installed and configured for the system. To install OpenJDK 11 on a new Teamwork Cloud server, execute the following command:

   Code Block
   language bash theme DJango linenumbers true
   yum -y install java-11-openjdk

   
   

2. Download the twcloud_<version_number>_installer_linux64.bin file and place it in the same location as the install_twc<version_number>_<os_version>.sh script.

3. Install Teamwork Cloud by executing the install_twc<version_number>_<os_version>.sh script.

   Code Block
   title Example
   sudo ./install_twc2022x_centos7.sh

   1. When executing the installation script, press ENTER until you are asked to configure the machine IP.
   2. Configure the machine IP by entering the local IP address or the host name of the machine (i.e. 192.168.130.10).
   3. Configure the cluster seed node IP by entering the local IP address or the host name of the machine (i.e. 19.168.130.10). 
   4. Configure the Teamwork Cloud service owner by entering twcloud.
   5. Configure JAVA_HOME by entering /etc/alternatives/jre_11.

   6. Press Enter to choose the default /opt/local/TeamworkCloud installation folder or type another installation folder address.

4. When the Teamwork Cloud pre-installation summary is displayed, follow the instructions on the screen. The summary should look like this:

   Code Block
   language bash
   =============================================================================== Pre-Installation Summary ------------------------ Please Review the Following Before Continuing: Product Name: Teamwork Cloud Install Folder: /opt/local/TeamworkCloud Machine ip: "192.168.130.10" Seed node ip: "192.168.130.10" JAVA_HOME: "/etc/alternatives/jre_11" Disk Space Information (for Installation Target): Required: 395,614,661 Bytes Available: 31,608,475,648 Bytes

   
   

   Note
   In the pre-installation summary, you should see the local IP address of your machine instead of "192.168.130.10" displayed in the example above.

   
   

5. Start the twcloud, zookeeper, and webapp services (in this particular order) by executing the following commands:

   Code Block
   language bash theme DJango linenumbers true
   sudo systemctl start twcloud sudo systemctl start zookeeper sudo systemctl start webapp

   
   

6. To ensure Teamwork Cloud services start after the reboot, execute the following commands:

   Code Block
   language bash theme DJango linenumbers true
   sudo systemctl enable twcloud sudo systemctl enable zookeeper sudo systemctl enable webapp

   
   

7. Make sure that Teamwork Cloud is operational by going to https://<server_address>:8443/webapp. You should see the Teamwork Cloud login screen.

   Info
   For more information, see Accessing Teamwork Cloud Admin.

   
   

When you complete the steps above, the preliminary Teamwork Cloud configuration is created. This means that your system is functional and you can login to Teamwork Cloud. After making sure that Teamwork Cloud is operational, you can optionally perform the post-installation configuration described in the section below.
