Upgrade to TeamForge 17.4 - Git on a separate server

Three server setup with TeamForge, Git/Gerrit, and EventQ on separate servers. In this procedure, we'll assume that you are upgrading on the same server where your existing TeamForge 17.1 site is running. The following instructions are valid for both RHEL/CentOS 6.8/7.3 platforms. Specific steps, if applicable only for a particular RHEL/CentOS platform, are called out explicitly.

Before you begin:

Plan your upgrade

Remember:

TeamForge 17.4 supports both RHEL/CentOS 6.8 and 7.3. See TeamForge installation requirements
For the ETL service to run as expected in a distributed TeamForge installation, all servers must have the same time zone.
While you can run both EventQ and TeamForge on the same server, CollabNet recommends such an approach only for testing purposes. It's always recommended to run EventQ on a separate server for optimal scalability. See EventQ installation requirements.
Installing or upgrading TeamForge needs root privileges. You must log on as root or use a root shell to install or upgrade TeamForge.
In a distributed setup, stop TeamForge services on all the servers while upgrading to TeamForge 17.4.

In this option, the following services run on the TeamForge Application Server (we call this server-01).

TeamForge Application Server (ctfcore)
Codesearch Server (codesearch)
Mail Server (mail)
ETL Server (etl)
Database Server (ctfcore-database and ctfcore-datamart)
SCM Integration Server (subversion and cvs)
Search Server (search)

The following service runs on the GIT Integration Server (we call this server-03).

Git Integration Server (gerrit and gerrit-database)

EventQ runs on a separate EventQ Server (server-02).

TeamForge EventQ Server (eventq, mongodb, redis and rabbitmq)

Do the following on the TeamForge Application Server - server-01

Back up all your custom event handlers and remove all the event handler JAR files before starting your TeamForge 17.4 upgrade process.
1. Go to My Workspace > Admin.
2. Click System Tools from the Projects menu.
3. Click Customizations.
4. Select the custom event handler and click Delete.
  Important: Post upgrade, you can add custom event handlers again from the backup while making sure that you don't have SOAP50 (deprecated) library used.
Uninstall hotfixes and add-ons, if any, installed on your site.
If you have Review Board installed, uninstall it.
- cd /opt/collabnet/RBInstaller-17.1.5
- python ./install.py -u
Stop the TeamForge CLI add-on.
- service teamforge_cli_server stop
Go to /var/run/cli/ and look for "server" file. If found, remove the "server" file.
- cd /var/run/cli/
- rm -rf /var/run/cli/server
Stop TeamForge.
If you are upgrading from TeamForge 16.7 or earlier releases:
- /etc/init.d/collabnet stop all
If you are upgrading from TeamForge 16.10 or later releases:
- /opt/collabnet/teamforge/bin/teamforge stop
Go to /opt/collabnet/teamforge/runtime/temp and look for .marker files. If found, remove the .marker files.
- cd /opt/collabnet/teamforge/runtime/temp
- rm -rf *.marker
No backup is required for same hardware upgrades. However, you can create a backup as a precaution. See Back up and restore TeamForge and EventQ to learn more about backing up TeamForge and EventQ database and file system.
Upgrade the operating system packages.
- yum upgrade
If the TeamForge server has SELinux enabled, run it in 'permissive' mode temporarily while installing or upgrading TeamForge.
If you have SELinux in "enforcing" mode, you must either disable SELinux or switch to "permissive" mode (recommended) before running the /opt/collabnet/teamforge/bin/teamforge provision command. TeamForge create runtime fails otherwise.
1. Verify if SELinux is running in enforcing mode.
  - getenforce
2. If the output of the getenforce command is "permissive", continue with the next step. If not, run the following command to bring it to 'permissive' mode.
  - setenforce 0
Configure your TeamForge installation repository.
- TeamForge installation repository configuration for sites with internet access
1. Contact the CollabNet Support and download the TeamForge 17.4 installation repository package to /tmp.
2. Install the repository package.
  - yum install -y /tmp/collabnet-teamforge-repo-17.4.27-1.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 17.4 disconnected installation and save it in /tmp.
  - Red Hat Enterprise Linux/CentOS 6.8 64 bit RPM package: CTF-Disconnected-media-17.4.824-110.rhel6.x86_64.rpm
  - Red Hat Enterprise Linux/CentOS 7.3 64 bit RPM package: CTF-Disconnected-media-17.4.824-110.rhel7.x86_64.rpm
    Note: In addition to the above CentOS 7.3 64 bit RPM package, you must get the following CentOS 7.3 compatibility RPM, which is required for TeamForge 17.4 disconnected media installation on CentOS 7.3 profile: compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm.
2. Unpack the disconnected installation package.
  - rpm -Uvh <package-name>
3. Unpack the compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm package if you are installing TeamForge 17.4 on CentOS 7.3.
  - 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
Install the following application packages.
1. To install the TeamForge application packages run the following command:
  - yum install teamforge
  Attention: TeamForge installer has been optimized quite a bit. It's likely that you might come across a lot of warning messages while upgrading from TeamForge 8.2 (or earlier) to TeamForge 17.4 on the same hardware (when you run the yum install teamforge command). You can safely ignore such warning messages and proceed with the upgrade.
  
  Run the following command to install the Binary application packages.
  - yum install cn-binary
Set up your site's master configuration file.
1. Set up your site options. See Site options change log for a list of site option changes. While upgrading to a latest TeamForge release, make sure that obsolete site option tokens, if any, are removed from the site-options.conf file of the TeamForge version you are upgrading to.
  - vi /opt/collabnet/teamforge/etc/site-options.conf
2. TeamForge 16.7 and later versions support automatic JAVA_HOME configuration. Remove the JAVA_HOME token, if present, from the site-options.conf file.
3. Configure the services and domain name tokens.
```
server-01:SERVICES = ctfcore mail search codesearch ctfcore-database etl ctfcore-datamart subversion cvs
```
```
server-01:PUBLIC_FQDN = my.app.domain.com
```
```
server-03:SERVICES = gerrit gerrit-database
```
  Add Binary identifiers if you are installing Nexus.
```
server-01:SERVICES = ctfcore mail search codesearch ctfcore-database etl 
ctfcore-datamart subversion cvs binary binary-database
```
  Add Review Board identifiers if you are installing Review Board.
```
server-01:SERVICES = ctfcore mail search codesearch ctfcore-database etl 
ctfcore-datamart subversion cvs binary binary-database reviewboard reviewboard-database
```
4. Attention: SSL is enabled by default and a self-signed certificate is auto-generated. Use the following tokens to adjust this behavior. To generate the SSL certificates, see Generate SSL certificates.
  Have the custom SSL certificate and private key for custom SSL certificate in place and provide their absolute paths in these tokens. SSL_CHAIN_FILE (intermediate certificate) is optional.
```
SSL_CERT_FILE=
```
```
SSL_KEY_FILE=
```
```
SSL_CHAIN_FILE=
```
  Important: All SSL certificates including self-signed certificates are added automatically.
5. If the token REQUIRE_PASSWORD_SECURITY is enabled, then set a value for the token, PASSWORD_CONTROL_EFFECTIVE_DATE.
  CAUTION:
  The Password Control Kit (PCK) disables, deletes or expires user accounts that don't meet the password security requirements starting from the date set for the PASSWORD_CONTROL_EFFECTIVE_DATE token. If a date is not set, the PCK disables, deletes or expires user accounts immediately. See PASSWORD_CONTROL_EFFECTIVE_DATE for more information.
6. TeamForge 7.1 and later support automatic password creation. See AUTO_DATA for more information.
7. Include the list of non-expiring TeamForge user accounts (password never expires).
```
USERS_WITH_NO_EXPIRY_PASSWORD=admin,nobody,system,scmviewer,scmadmin
```
8. If you have LDAP set up for external authentication, you must set the “REQUIRE_USER_PASSWORD_CHANGE” site options token to false.
9. 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?
10. Enable the POSTGRES_INTERFACE token in the site-options.conf file if the value of "ifconfig -a" is not eth0/enp0*.
11. Configure the JBOSS_JAVA_OPTS site-options.conf token. See JBOSS_JAVA_OPTS.
  Important: All JVM parameters but -Xms1024m and -Xmx2048m have been hard-coded in the TeamForge core application. You cannot manually configure any of the following default JVM parameters in the site-options.conf file.
  - -XX:+UseParallelGC
  - -XX:MaxMetaspaceSize=512m
  - -XX:ReservedCodeCacheSize=128M
  - -server
  - -XX:+HeapDumpOnOutOfMemoryError
  - -XX:HeapDumpPath=/tmp -verbose:gc
  - -XX:+PrintCodeCache
  - -Djsse.enableSNIExtension=false
  - -Dsun.rmi.dgc.client.gcInterval=600000
  - -Dsun.rmi.dgc.server.gcInterval=600000
  - -Djava.security.egd=file:/dev/urandom
  - -Djava.awt.headless=true.
  When you change the default value of a JVM parameter such as "-XX:HeapDumpPath", the JBoss runtime parameters include both the user defined and default values for the JVM parameter. However, JBoss runs with the default value and ignores any user defined value.
12. Configure TeamForge site options to proxy EventQ through TeamForge. For more information, see "EventQ and TeamForge on two separate servers" section in this topic: Proxying EventQ through TeamForge. Also see Ports used by TeamForge EventQ services.
13. Save the site-options.conf file.
Deploy services.
1. Move all backup files and folders including the error folder to /tmp.
  Note: This step is required to make sure that there are no backup files and folders present in /opt/collabnet/teamforge/var/james/var/mail/ to avoid any delay during provisioning.
  - cd /opt/collabnet/teamforge/var/james/var/mail/
  - mv * /tmp
2. Run the TeamForge provision command.
  - /opt/collabnet/teamforge/bin/teamforge provision
Note:
The "provision" command prompts for response before it bootstraps or migrates data during TeamForge installation and upgrade respectively. Enter "Y" or "N" to proceed. For more information, see TeamForge script.

TeamForge 17.4 (and later) installer expects the system locale to be LANG=en_US.UTF-8. TeamForge "provision" command fails otherwise.
Update the file permissions on your site's data.
- /opt/collabnet/teamforge/runtime/scripts/fix_data_permissions.sh
Note: This process can take a long time on sites with a lot of data.
If you have CVS integrations, synchronize permissions post upgrade. See, Synchronize TeamForge source control integrations.
Run the TeamForge post installation script. For more information, see post-install.py.
1. Use the following command to run the post-install.py script.
  - /opt/collabnet/teamforge/runtime/scripts/post-install.py
  Note: Enter the 'gitadmin' user name and password when prompted.

Do this on the Git Integration Server - server-03

Back up the Git file system data.

Make an archive file with the following data directories.

Tip: /tmp is just an example. You can use any directory or partition that you prefer.

Directory	Contents
/gitroot	Git source code repositories

cp -Rpfv /gitroot /tmp/gitbackup_dir
cp -Rpfv /opt/collabnet/gerrit/ /tmp/gitbackup_dir/gerrit

Back up your SSH keys, if any.

Upgrade the operating system packages.
- yum upgrade
If the TeamForge server has SELinux enabled, run it in 'permissive' mode temporarily while installing or upgrading TeamForge. TeamForge create runtime fails otherwise.
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 bring it to 'permissive' mode.
  - setenforce 0
