Install Git on a separate server

In this setup, we install the Git integration services on a separate server.

1. Install Red Hat Enterprise Linux/CentOS 7.2 and log in as root.
   • Don't customize your installation. Select only the default packages list.
   • Red Hat Enterprise Linux/CentOS 6.8 is also supported. See TeamForge installation requirements.
   • The host must be registered with the Red Hat Network if you are using Red Hat Enterprise Linux.
   • See the Red Hat installation guide for help.
2. Check your basic networking setup. See Set up networking for your TeamForge server for details.
3. If the Git server has SELinux enabled, disable it temporarily while installing or upgrading Git.
   1. Verify if SELinux is running in enforcing mode.
      • getenforce
   2. If the output of the getenforce command is either "Disabled" or "Permissive", SELinux is already disabled.
   3. If not disabled, run the following command to disable SELinux.
      • setenforce 0
4. Configure your TeamForge installation repository.
   • TeamForge installation repository configuration for sites with internet access
   1. Contact the CollabNet Support and download the TeamForge 16.10 installation repository package to /tmp.
   2. Install the repository package.
      • yum install -y /tmp/collabnet-teamforge-repo-16.10-1.noarch.rpm
   3. Refresh your repository cache.
      • yum clean all
   • TeamForge installation repository configuration for sites without internet access
   1. Contact the CollabNet Support to get the auxiliary installer package for TeamForge 16.10 disconnected installation and save it in /tmp.
      • Red Hat Enterprise Linux/CentOS 7.2 64 bit RPM package: CTF-Disconnected-media-16.10.658-76.rhel7.x86_64.rpm
        Note: In addition to the above CentOS 7.2 64 bit RPM package, you must get the following CentOS 7.2 compatibility RPM, which is required for TeamForge 16.10 disconnected media installation on CentOS 7.2 profile: compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm.
   2. Unpack the disconnected installation package.
      • rpm -ivh <package-name>
   3. Unpack the compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm package if you are installing TeamForge 16.10 on CentOS 7.2.
      • rpm -ivh compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm
   4. Note: If the Red Hat Enterprise Linux/CentOS installation DVD is mounted already, skip the following instructions. If not, mount the DVD.
      Mount the Red Hat Enterprise Linux/CentOS installation DVD. The DVD contains the necessary software and utilities required for installing TeamForge without internet access.

      In the following commands, replace "cdrom" with the identifier for your server's CD/DVD drive, if necessary.

      • cd /media/
      • mkdir cdrom
      • mount /dev/cdrom ./cdrom/

      If there are any spaces in the automount, unmount it first and mount it as a filepath, with no spaces.

   5. Create a yum configuration file that points to the Red Hat Enterprise Linux/CentOS installation DVD.
      • vi /etc/yum.repos.d/cdrom.repo
      Here's a sample yum configuration file.

      [RHEL-CDROM] 
      name=RHEL CDRom 			
      baseurl=file:///media/cdrom/Server/
      gpgfile=file:///media/cdrom/RPM-GPG-KEY-redhat-release 
      enabled=1
      gpgcheck=0

   6. Verify your yum configuration files.
      • yum list httpd
      • yum list apr
5. Install the Git packages.
   • yum install teamforge-git
6. Configure the token settings for Git in the site-options.conf file.
   • vi /opt/collabnet/teamforge/etc/site-options.conf
   1. Modify the host token settings.

      HOST_server-03=gerrit

      DOMAIN_server-03=my.git.domain.com

      HOST_my.app.domain.com=app database datamart etl indexer subversion cvs binary reviewboard

   2. To enable the history protection feature of TeamForge Git integration, set the GERRIT_FORCE_HISTORY_PROTECTION=true. For more information, see GERRIT_FORCE_HISTORY_PROTECTION.
   3. Turn on the SSL for your site by editing the relevant variables in the site-options.conf file. To generate the SSL certificates, see Generate SSL certificates.

      SSL=on

      SSL_CERT_FILE

      SSL_KEY_FILE

      SSL_CHAIN_FILE

      Note: The SSL_CERT_FILE and SSL_KEY_FILE tokens need an absolute path. The SSL_CHAIN_FILE token is optional.
   4. Make sure the PostgreSQL tokens in the site-options.conf file are set as recommended in the following topic: What are the right PostgreSQL settings for my site?
   5. Enable the POSTGRES_INTERFACE token in the site-options.conf file if the value of "ifconfig -a" is not eth0/enp0*.
   6. Save the site-options.conf file.
7. Deploy services.
   • /opt/collabnet/teamforge/bin/teamforge provision

   The "provision" command prompts for response before it bootstraps or migrates data during TeamForge installation and upgrade respectively. Enter "Yes" or "No" to proceed. For more information, see The teamforge script.

8. Run the TeamForge post installation script. For more information, see post-install.py.
   • /opt/collabnet/teamforge/runtime/scripts/post-install.py
