Installing services

This chapter explains how to install Magic Collaboration Studio services by using the install_twc_mcs_centos_rhel.sh installation script.

To install Magic Collaboration Studio services

---

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 Magic Collaboration Studio server, execute the following command:

   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_mcs_centos_rhel.sh script.

3. Install Magic Collaboration Studio by executing the install_twc_mcs_centos_rhel.sh script.

   Example

   sudo ./install_twc_mcs_centos_rhel.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. 192.168.130.10). 
   4. Configure the Magic Collaboration Studio service owner by entering twcloud.
   5. Configure JAVA_HOME by entering /etc/alternatives/jre_11.

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

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

   ===============================================================================
   Pre-Installation Summary
   ------------------------
   Please Review the Following Before Continuing:
     
   Product Name:
       Magic Collaboration Studio
     
   Install Folder:
       /opt/local/CATIANoMagicServices
     
   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

   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:

   sudo systemctl start twcloud
   sudo systemctl start zookeeper
   sudo systemctl start webapp

6. To ensure Magic Collaboration Studio services start after the reboot, execute the following commands:

   sudo systemctl enable twcloud
   sudo systemctl enable zookeeper
   sudo systemctl enable webapp

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

   For more information, see Accessing Magic Collaboration Studio web applications.

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

Post-installation Magic Collaboration Studio Configuration

To perform the post-installation Magic Collaboration Studio configuration

---

1. Edit the /opt/local/CATIANoMagicServices/TeamworkCloud/configuration/application.conf configuration file and make the following changes:
   
   • Change the value of the contact-points property to point to the listen_address you set in the cassandra.yaml file (i.e., contact-points = ["192.168.130.10:9042"]). This points Magic Collaboration Studio to the Cassandra database.
   • Use this parameter only if you need to deploy Magic Collaboration Studio in private network but client connect from public network. Change the value of the server-broadcast-host property to the public IP address instead of the local IP address. This way upon the initial connection the client application will know the external IP address to which it must connect (if Magic Collaboration Studio is installed behind a proxy or firewall with NAT).

2. Edit the /opt/local/CATIANoMagicServices/WebAppPlatform/shared/conf/authserver.properties configuration file and make the following changes:

   • Change the value of the cassandra.contactPoints property to the local IP address.

   • If you are accessing the server by FQDN, change the value of the authentication.redirect.uri.whitelist property by adding an the FQDN entry to the whitelist (e.g., authentication.redirect.uri.whitelist=https://FQDN:8443/,https://FQDN:8111/,https://md_redirect). Make sure to add the public IP and/or FQDN for ports 8443 and 8111 to the whitelist.

3. Edit the /opt/local/CATIANoMagicServices/WebAppPlatform/shared/conf/webappplatform.properties configuration file and make the following changes:
   
   • Change the value of the twc.admin.username property to the username of a local account with Administrator privileges (the default value is Administrator).
   • Change the value of the twc.admin.password property to the password corresponding to the Administrator user (the default value is Administrator).
4. Restart the affected Magic Collaboration Studio services.
