Gitlab该如何升级?

各位用Gitlab的小伙伴们,你们的Gitlab升级了吗?还是一直未升级过呢?又或者是已经很久没升级了?仔细想想博主第一升级gitlab的时候是2019年中之时,当时的需求是将7.x升级12.x。当时公司项目不是很多,人员和用户组也是很少,所以便没有进行升级,而是进行仓库迁移,用户权限全部新建。而且我们当时还有gitea这个仓库,也一并迁移仓库到了gitlab。当时迁移就是用gitlab控制台中的仓库导入功能即可,没啥技术含量~

近期博主又遇到升级需求,特此记录下。此时就不是gitlab导入远程仓库这么简单了,因为这种方式只适用于项目工程少的场景。目前的场景项目工程和用户、组都很庞大,只能一步一步走升级流程了。目前的版本依旧是7.x,目标升级到15.x,且运行环境从ecs转为k8s中。。。

官方升级文档:https://docs.gitlab.com/ee/update/,从官方的升级建议来看,博主可能需要升级20+个版本的`(*>﹏<*)′,而且官方镜像只有8.x开始

7.x -> 8.0.5 -> 8.12.0 -> 8.17.7 -> 9.5.10 -> 10.8.7 -> 11.11.8 -> 12.0.12 -> 12.1.17 -> 12.10.14 -> 13.0.14 -> 13.1.11 -> 13.8.8 -> 13.12.15 -> 14.0.12 -> 14.3.6 -> 14.9.5 -> 14.10.Z -> 15.0.Z -> 15.4.0 -> latest 15.Y.Z

因为不能跳大版本升级,所以我们按官方上述的版本升级来制定下升级和平台迁移计划

Gitlab该如何升级?

模拟场景

terraform创建基础层资源

模拟上图需要准备以下基础资源,读者模拟测试可以自行缩减,此处只是为了最大复原场景

  • 两台ecs(原服务器、新服务器)
  • 一个k8s集群
    • 一个内网slb
    • 三台ecs(master,ingress node/app node)
    • 一个nas

使用rpm包安装gitlab7.x

两台ecs都安装gitlab7.x

# 安装依赖
yum install -y curl policycoreutils-python openssh-server postfix git 
systemctl enable sshd
systemctl start sshd
systemctl enable postfix
systemctl start postfix

# 下载安装包
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-7.14.3-ce.1.el7.x86_64.rpm
rpm -ivh gitlab-ce-7.14.3-ce.1.el7.x86_64.rpm

# 编辑配置文件,该配置文件需要证书,请自行准备并放置好
egrep -v config/gitlab.rb '^$|^#' 
external_url 'https://gitlab.xadocker.cn' # default: http://hostname
nginx['enable'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.xadocker.cn.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.xadocker.cn.key"

# 初始化gitlab各组件
gitlab-ctl reconfigure

# 查看服务状态
gitlab-ctl status

第一台giilab服务器控制台远程导入样例仓库数据

快速搭建k8s集群

初始化master

新增两个节点

安装并配置ingress

安装nfs-subpath插件

部署gitlab 8.x statefulset

开始升级

gitlab节点1备份并迁移数据至gitlab节点2

# 创建备份数据

gitlab-backup create

# 查看备份文件
ll /var/opt/gitlab/backups


# 备份配置文件,若有ssl证书,也复制过去
mkdir /var/opt/gitlab/backups/conf/
\cp /etc/gitlab/gitlab.rb /var/opt/gitlab/backups/conf/
\cp /etc/gitlab/gitlab-secrets.json  /var/opt/gitlab/backups/conf/
\cp /var/opt/gitlab/nginx/conf/nginx.conf  /var/opt/gitlab/backups/conf/
tar -zvcf gitlab.conf.tar.gz /var/opt/gitlab/backups/conf/

# 备份数据再/var/opt/gitlab/backups,将数据复制到新服务器上
scp 1665213562_gitlab_backup.tar gitlab.conf.tar.gz root@xxxxxxxx:/xxxx

gitlab节点2通过备份数据还原

# 通过备份数据还原时需要停止以下两个服务
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

# 查看当前服务状态
gitlab-ctl status

#开始通过备份数据还原
[root@localhost backups]# ll

-rw-------. 1 git git 10485760 Oct  8 15:35 1665213562_gitlab_backup.tar
[root@localhost backups]# gitlab-rake gitlab:backup:restore BACKUP=1665213562

# 还原配置文件
tar -zvxf gitlab.conf.tar.gz
cp /var/opt/gitlab/backups/conf/gitlab.rb /etc/gitlab/gitlab.rb
cp /var/opt/gitlab/backups/conf/gitlab-secrets.json /etc/gitlab/gitlab-secrets.json
cp /var/opt/gitlab/backups/conf/nginx.conf /var/opt/gitlab/nginx/conf/nginx.conf 

# 重新启动所有服务,完成备份恢复
[root@localhost backups]# gitlab-ctl restart
ok: run: logrotate: (pid 11847) 0s

ok: run: redis: (pid 11870) 1s
ok: run: sidekiq: (pid 11874) 0s
ok: run: unicorn: (pid 11878) 0s

# 修改gitlab.xadocker.cn的dns解析,略

gitlab节点2用rpm包原地升级至8.x

# 先备份数据
gitlab-rake gitlab:backup:create

# 备份配置文件,若有ssl记得备份
mkdir /var/opt/gitlab/backups/conf
\cp /etc/gitlab/gitlab.rb /var/opt/gitlab/backups/conf/
\cp /etc/gitlab/gitlab-secrets.json  /var/opt/gitlab/backups/conf/
\cp /var/opt/gitlab/nginx/conf/nginx.conf  /var/opt/gitlab/backups/conf/

# 停止服务,只保留postgresql
gitlab-ctl stop
gitlab-ctl start postgresql
gitlab-ctl status

# 卸载旧版gitlab
rpm -e gitlab-ce

# 安装新版gitlab
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-8.0.5-ce.0.el7.x86_64.rpm
rpm -Uvh gitlab-ce-8.0.5-ce.0.el7.x86_64.rpm

# 初始化各组件,此时初始化会自动将7.x的数据升级到8.0
gitlab-ctl reconfigure

# 查看此时版本信息
[root@localhost ~]# gitlab-rake gitlab:env:info

gitlab节点2备份并迁移数据至k8s集群的gitlab pod中

# 先备份数据
gitlab-rake gitlab:backup:create

# 将数据迁移到gitlab pod中
# 将nas挂载到gitlab node2的mnt上
mount -t nfs xxxxxx /mnt
scp 1665213562_gitlab_backup.tar /mnt/gitlab/data/gitlab

gitlab pod通过备份数据还原

# 进入pod中将数据还原
kubectl exec -it 

# 通过备份数据还原时需要停止以下两个服务
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

# 查看当前服务状态
gitlab-ctl status

# 开始还原数据
gitlab-rake gitlab:backup:restore BACKUP=1665213562

# 重新启动服务
# gitlab-ctl restart

gitlab pod替换镜像版本来升级

14.x及以上版本升级时出现以下问题

StandardError: An error has occurred, all later migrations canceled:

Expected batched background migration for the given configuration to be marked as 'finished', but it is 'active':
  {:job_class_name=>"CopyColumnUsingBackgroundMigrationJob", :table_name=>"push_event_payloads", :column_name=>"event_id", :job_arguments=>[["event_id"], ["event_id_convert_to_bigint"]]}

是因为后台任务未执行完成,需要等任务执行完成才可以进行升级:

  1. 在顶部栏上,选择菜单 > 管理
  2. 在左侧边栏上,选择Monitoring > Background Migrations查看后台任务,存在active状态的则是再运行中,等待变为finished后再升级(10分钟左右)
