Upgrade EventQ on a separate server

Instructions to upgrade EventQ on a separate server. You can choose to upgrade EventQ either on the same hardware or on a new hardware. Steps that are relevant only to same and new hardware upgrades are called out explicitly.

It is assumed that you have TeamForge 17.8 up and running. The TeamForge services are distributed as listed in the following table:

Services	TeamForge Application Server (server-01)	EventQ Server (server-02)
ctfcore
mail
search
codesearch
etl
gerrit
gerrit-database
reviewboard
reviewboard-database
reviewboard-adapter
subversion
cvs
binary
binary-database
cliserver
eventq
mongodb
redis
rabbitmq
ctfcore-database
ctfcore-datamart

New hardware upgrade: Backup steps required only if you are upgrading EventQ on a new hardware. Do this on the existing EventQ server.
1. Stop EventQ.
  If you are upgrading from TeamForge 16.3 to TeamForge 17.8 (or later):
  - /etc/init.d/orchestrate stop
  If you are upgrading from TeamForge 17.1 (or earlier) to TeamForge 17.8 (or later):
  - /etc/init.d/eventq stop
  - /etc/init.d/collabnet-rabbitmq-server stop
  - /etc/init.d/collabnet-mongod stop
  Use the following command otherwise:
  - /opt/collabnet/teamforge/bin/teamforge stop
2. Back up the /opt/collabnet/eventq/config/ data directory, compress and copy the backup file to the new server.
  - mkdir /tmp/backup_dir
  - cp -Rpf /opt/collabnet/eventq/config/*.yml /tmp/backup_dir
  - cp -Rpf /opt/collabnet/mongodb /tmp/backup_dir
  - cp -Rpf /opt/collabnet/rabbitmq /tmp/backup_dir
  - tar czvf eventqbackup.tgz backup_dir
  - scp /tmp/eventqbackup.tgz username@newbox:/tmp
Same hardware upgrade: Upgrade the operating system packages in case of same hardware upgrade.
- sudo yum upgrade

EventQ upgrade steps

Configure your TeamForge installation repository.
- TeamForge installation repository configuration for sites with internet access
1. Contact the CollabNet Support and download the TeamForge 17.8 installation repository package to /tmp.
2. Install the repository package.
  - yum install -y /tmp/collabnet-teamforge-repo-17.8-1.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 17.8disconnected installation and save it in /tmp.
  - Red Hat Enterprise Linux/CentOS 7.3 64 bit RPM package: CTF-Disconnected-media-17.8.655-104.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 17.8 disconnected media installation on CentOS 7.3 profile: compat-ctf-dc-media-1.1-1.el7.noarch.rpm.
2. Unpack the disconnected installation package.
  - rpm -Uvh <package-name>
3. Unpack the compat-ctf-dc-media-1.1-1.el7.noarch.rpm package if you are installing TeamForge 17.8 on CentOS 7.3.
  - rpm -ivh compat-ctf-dc-media-1.1-1.el7.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.
- yum install teamforge-eventq CN-eventq collabnet-nginx collabnet-passenger
Important: The following warning message, which shows up during TeamForge install/upgrade (while installing CN-eventq rpm) can be safely ignored.
```
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
...
...
Errno::ENOENT: No such file or directory - git
...
...
```
Copy the site-options.conf file from the TeamForge Application Server(server-01) to the EventQ Server's /opt/collabnet/teamforge/etc/ directory.
- Adjust the SERVICES and PUBLIC_FQDN tokens, if required.
```
server-01:SERVICES=ctfcore ctfcore-database ctfcore-datamart mail etl search codesearch 
subversion cvs cliserver gerrit gerrit-database binary binary-database reviewboard reviewboard-database 
reviewboard-adapter
```
```
server-02:SERVICES=eventq mongodb redis rabbitmq
```
```
server-01:PUBLIC_FQDN=my.app.domain.com
```
- Make sure you set the MONGODB_APP_DATABASE_NAME site options token.
```
MONGODB_APP_DATABASE_NAME=orchestrate
```
- If your mongodb user name is different from the default user name which is "eventq", set the token MONGODB_APP_SERVICES_USER in the site-options.conf file. For example, set MONGODB_APP_SERVICES_USER=orchestrate.
New hardware upgrade: Do this on the new EventQ server. Uncompress your backup data and copy the backed up data to the /opt/collabnet/eventq/config directory.
- cd /tmp
- tar xzvf eventqbackup.tgz -C /tmp/
- cd /tmp/backup_dir
- cp -Rpf *.yml /opt/collabnet/eventq/config/
- cp -Rpf mongodb/ /opt/collabnet/mongodb
- cp -Rpf rabbitmq/ /opt/collabnet/rabbitmq
Provision services.
- teamforge provision
Note:
TeamForge 17.4 (and later) installer expects the system locale to be LANG=en_US.UTF-8. TeamForge "provision" command fails otherwise.
