1 起因
原机器到期需要迁移到新机器上，为了节省机器先把gitlab和禅道放在一台机器上
原机器是centos7.6 新机器是centos6.9
2 迁移
1> 查看gitlab版本
需要同版本迁移，如果想升级到最高版，可以先升级，再备份
查看版本
cat /opt/gitlab/embedded/service/gitlab-rails/VERSION
2>old机器备份
gitlab-rake gitlab:backup:create
默认将会在 /var/opt/gitlab/backups/ 目录下生成备份文件
3>new机器还原
old机器版本为12.0.4 我没有升级直接在新机器上安装的12.0.4版本
安装-具体安装可参考之前文档
yum -y install gitlab-ce-12.4.0 --nogpgcheck
将备份的数据1587448920_2020_04_21_12.4.0_gitlab_backup.tar拷贝到新机器上
执行还原
gitlab-rake gitlab:backup:restore BACKUP=备份文件编号
#gitlab-rake gitlab:backup:restore BACKUP=1587448920_2020_04_21_12.4.0
重新启动gitlab-ctl start即可
备份
vim /etc/gitlab/gitlab.rb
修改备份目录和时间
gitlab_rails['backup_path'] = "/data/gitlab_bak/backups"
gitlab_rails['backup_keep_time'] = 2592000
设置备份过期时间//2592000 秒为单位，代表30天
定时任务
0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create > /dev/null 2>&1 &
4>遇到问题
注意1：一定要同版本迁移
注意2：安装时遇到redis无法正常启动问题，注意查看log并根据log提示进行处理，如log位置
/var/log/gitlab/redis/current
注意3：避免端口冲突注意修改端口，因为这台机器之前有nginx，所以将gitlab的nginx端口修改为8999，然后再在原有nginx上配置80跳8999访问
注意4：
迁移后之前的项目（迁移之前创建的项目）修改项目描述报错【新创建的项目不影响】

打开日志gitlab-ctl tail

修改gitlab配置报错500

日志报错

后查看得知这是gitlab迁移的bug
需要修改数据库
-bash-4.1# gitlab-rails dbconsole
psql (10.9)
Type "help" for help.
gitlabhq_production=> UPDATE projects SET runners_token = null, runners_token_encrypted = null;
UPDATE 21
gitlabhq_production=> UPDATE namespaces SET runners_token = null, runners_token_encrypted = null;
UPDATE 20
gitlabhq_production=> UPDATE application_settings SET runners_registration_token_encrypted = null;
UPDATE 1
gitlabhq_production=> UPDATE application_settings SET encrypted_ci_jwt_signing_key = null;
ERROR: column "encrypted_ci_jwt_signing_key" of relation "application_settings" does not exist
LINE 1: UPDATE application_settings SET encrypted_ci_jwt_signing_key...
^
gitlabhq_production=> UPDATE ci_runners SET token = null, token_encrypted = null;
UPDATE 0
gitlabhq_production=>
重启gitlab后生效，当然要跟你你的报错来修改数据库，我这边是 Reset runner registration tokens 重置了这块好的
具体参考

gitlab升级
有漏洞需要升级，没有直接升级到大版本，而是小版本小版本升级
参考：
https://docs.gitlab.com/ee/update/index.html#upgrade-paths

yum -y install gitlab-ce-13.0.14 --nogpgcheck
yum -y install gitlab-ce-13.1.11 --nogpgcheck
yum -y install gitlab-ce-13.6.7 --nogpgcheck
升级完一个版本后进行测试，没问题再进行下一个版本
注意：
centos6的官网最高到gitlab-ce-13.6.7，centos7的可以到14版本
官网源地址：
https://packages.gitlab.com/app/gitlab/gitlab-ce/search?dist=ol%2F6&page=13
卸载
gitlab-ctl stop
rpm -e gitlab-ce
ps aux | grep gitlab
find / -name gitlab | xargs rm -rf
/opt/gitlab /etc/gitlab /var/opt/gitlab /var/log/gitlab
安装
yum -y install gitlab-ce-13.6.7 --nogpgcheck
启动
cd /etc/gitlab/
mv gitlab.rb /root
cp /backup/gitlab_bak/gitlab.rb.20220331 gitlab.rb
cat gitlab.rb |grep -v "#"|grep -v "^$"
gitlab-ctl reconfigure
登录修改密码
数据备份
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
gitlab-rake gitlab:backup:create

刚开始搜索全都是/var/opt/gitlab目录权限问题但是后来发现并不是而是当时我对/etc/passwd r权限锁紧导致
原因是系统切换时报错
/usr/bin/id: cannot find name for user ID 491
后来发现是/etc/passwd /etc/group没有r权限导致
一个小小的错误导致git无法访问了，记录一下
