gitlab搭建

1.安装依赖项

suo apt update
sudo apt upgrade -y
sudo apt install ca-certificates curl openssh-server postfix

2.添加gitlab-ce存储库

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

3.安装gitlab-ce

sudo apt update

sudo EXTERNAL_URL="http://gitlab.example.com" apt -y install gitlab-ce

 在执行命令之前，将gitlab.example.com替换为你的实际域名。完成后，通过运行以下命令启动GitLab实例：

sudo gitlab-ctl reconfigure

配置后应启动所有的GitLab服务：

gitlab 备份

停止用户连接

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
gitlab-ctl stop nginx

创建备份

gitlab-rake gitlab:backup:create

如果出错请检查权限问题 我的是默认root
可以加sudo重新试一下

gitlab升级

gitlab普通升级就正常升级就可以了
 升级不能跨越大版本号，因此只能升级到当前大版本号到最高版本，
方可升级到下一个大版本号

如果是跨大版本升级要严格按照官方指导的升级顺序进行
参考:
https://docs.gitlab.com/ce/policy/maintenance.html

先停止用户连接
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
gitlab-ctl stop nginx

创建备份:
gitlab-rake gitlab:backup:create

然后安装升级
例如我从清华软件源下载好的deb安装包
直接dpkg -i 安装就行了
rpm包也是
也可以直接在线升级

gitlab迁移恢复

1.执行备份数据
2.在目标机器中搭建与执行备份相同版本的gitlab
 版本一定要相同
3.将备份的tar包复制到目标机器备份目录
 默认路径为:/var/opt/gitlab/backups/
4.恢复数据

依然要把这些服务停掉
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
gitlab-ctl stop nginx

然后执行
gitlab-rake gitlab:backup:restore BACKUP=备份文件gitlab_backup.tar前面的数字

---

正常情况下就是以上这些步骤了
如果你整个过程顺顺利利的那么到这里就结束了

但是我的过程中充满了曲折
以下是我遇到的一些错误
仅以记录供参考

---

处理gitlab升级时的错误

错误信息

错误原因:端口占用

修改默认端口
找到gitlab.rb这个配置文件
external_url 'http://你的域名:8082'
把最后的端口修改成别空的端口

使配置生效

gitlab-ctl reconfigure

重新启动GitLab

gitlab-ctl restart
即可生效

备份时遇到的错误

Dumping database ... 
Dumping PostgreSQL database gitlabhq_production ... pg_dump: [archiver (db)] connection to database "gitlabhq_production" failed: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/opt/gitlab/postgresql/.s.PGSQL.5432"?
[FAILED]
Backup failed

原因:

postgresql 没有启动
参考https://www.tlanyan.me/deal-gitlab-upgrade-error/

解决办法

sudo gitlab-ctl start postgresql

reconfigure过程中的一个错误

解决办法

export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
sudo dpkg-reconfigure locales

reconfigure过程中的另一个错误

在升级完成 执行gitlab-ctl reconfigure的时候出现

Error executing action `run` on resource 'execute[initctl status gitlab-runs

解决办法

参照的这个
http://www.doc88.com/p-2542809540436.html
我也没看太懂原理
反正好使 回头再研究

截图

至此 gitlab总算启动起来了
感谢google&baidu各路大神
