Gitlab迁移

目标：Gitlab服务器迁移，需要在新服务器安装及数据同步。

Step1：原Gitlab数据备份

$ gitlab-rake gitlab:backup:create

Step2: 安装新Gitlab

$ rpm -ivh gitlab-ce-9.1.3-ce.0.el6.x86_64.rpm

gitlab: Thank you for installing GitLab!
gitlab: To configure and start GitLab, RUN THE FOLLOWING COMMAND:

sudo gitlab-ctl reconfigure

gitlab: GitLab should be reachable at http://demo
gitlab: Otherwise configure GitLab for your system by editing /etc/gitlab/gitlab.rb file
gitlab: And running reconfigure again.
gitlab:
gitlab: For a comprehensive list of configuration options please see the Omnibus GitLab readme
gitlab: https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
gitlab:
It looks like GitLab has not been configured yet; skipping the upgrade script.

安装之后调整配置，配置文件：/etc/gitlab/gitlab.rb

gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"

external_url 'http://gitlab.test.com'

git_data_dirs({ "default" => { "path" => "/data/git-data", 'gitaly_address' => 'unix:/var/opt/gitlab/gitaly/gitaly.socket' } })

然后执行：

$ gitlab-ctl reconfigure

然后会自动创建用户以及git-data目录。查看状态，可以看到已经都启动了

$ gitlab-ctl status
run: gitaly: (pid 13300) 3618777s; run: log: (pid 8252) 3619408s
run: gitlab-monitor: (pid 13310) 3618777s; run: log: (pid 8616) 3619388s
run: gitlab-workhorse: (pid 13322) 3618776s; run: log: (pid 8286) 3619406s
run: logrotate: (pid 16000) 764s; run: log: (pid 8347) 3619402s
run: nginx: (pid 13347) 3618776s; run: log: (pid 8320) 3619404s
run: node-exporter: (pid 13360) 3618775s; run: log: (pid 8486) 3619394s
run: postgres-exporter: (pid 13372) 3618775s; run: log: (pid 8583) 3619390s
run: postgresql: (pid 13383) 3618774s; run: log: (pid 7979) 3619438s
run: prometheus: (pid 13398) 3618774s; run: log: (pid 8453) 3619396s
run: redis: (pid 13414) 3618774s; run: log: (pid 7907) 3619444s
run: redis-exporter: (pid 13423) 3618773s; run: log: (pid 8530) 3619392s
run: sidekiq: (pid 13434) 3618773s; run: log: (pid 8237) 3619410s
run: unicorn: (pid 13437) 3618772s; run: log: (pid 8196) 3619412s

Step3: 数据迁移。同步备份文件到backups目录，按下面操作输入2个yes后即可。

$ gitlab-ctl stop unicorn 
$ gitlab-ctl stop sidekiq
$ gitlab-rake gitlab:backup:restore BACKUP=1622519542_2021_06_01
$ gitlab-ctl restart
