Gitlab仓库迁移

1、服务器环境信息

旧Gitlab：192.168.2.199

新Gitlab：192.168.2.200

2、在新服务器安装相同版本的Gitlab

注意：新服务器gitlab版本也需要和旧版本一致。

1）查看原Gitlab版本号

[root@localhost ~]# cat /opt/gitlab/embedded/service/gitlab-rails/VERSION

16.2.4

2）安装Gitlab 16.2.4

[root@node_192 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-16.2.4-ce.0.el7.x86_64.rpm

[root@node_192 ~]# yum -y install gitlab-ce-16.2.4-ce.0.el7.x86_64.rpm

3、备份原Gitlab数据

1）备份配置文件gitlab.rb和gitlab-secrets.json

注意：/etc/gitlab/gitlab-secrets.json文件，此文件中包含数据库加密密钥，CI/CD变量以及双因子认证等变量信息，如果在GitLab中使用到此部分内容，必须进行此文件的手动恢复。

[root@localhost ~]# scp /etc/gitlab/gitlab.rb root@192.168.2.200:/etc/gitlab/

[root@node_192 ~]# gitlab-ctl reconfigure

2）数据备份

[root@localhost ~]# gitlab-rake gitlab:backup:create

3）传输备份到新服务器

[root@node_192 ~]# mkdir -p /var/opt/gitlab/backups

[root@localhost ~]# scp /var/opt/gitlab/backups/1725431200_2024_09_04_16.2.4_gitlab_backup.tar root@192.168.2.200:/var/opt/gitlab/backups/

[root@node_192 ~]# chmod 777 /var/opt/gitlab/backups/1725431200_2024_09_04_16.2.4_gitlab_backup.tar

4、还原Gitlab数据

1）停止unicorn和sidekiq服务，puma服务

[root@node_192 ~]# gitlab-ctl stop nginx

ok: down: nginx: 0s, normally up

[root@node_192 ~]# gitlab-ctl stop puma

ok: down: puma: 0s, normally up

[root@node_192 ~]# gitlab-ctl stop unicorn

[root@node_192 ~]# gitlab-ctl stop sidekiq

ok: down: sidekiq: 0s, normally up

2）恢复数据

[root@node_192 ~]# gitlab-rake gitlab:backup:restore BACKUP=1725431200_2024_09_04_16.2.4

3）替换gitlab-secrets.json文件

[root@localhost ~]# scp /etc/gitlab/gitlab-secrets.json root@192.168.2.200:/etc/gitlab/

4）重启Gitlab

[root@node_192 ~]# gitlab-ctl restart

ok: run: gitaly: (pid 18473) 0s

ok: run: gitlab-exporter: (pid 18514) 0s

ok: run: gitlab-kas: (pid 18535) 0s

ok: run: gitlab-workhorse: (pid 18542) 0s

ok: run: logrotate: (pid 18557) 1s

ok: run: nginx: (pid 18563) 0s

ok: run: postgresql: (pid 18582) 1s

ok: run: puma: (pid 18607) 0s

ok: run: redis: (pid 18636) 0s

ok: run: sidekiq: (pid 18643) 1s

5）访问Gitlab

# 浏览器输入http://192.168.2.200，如下图所示

至此，Gitlab恢复完成。
