CentOS7下安装GitLab

---

一、下载地址

Gitlab下载地址：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

二、安装

1.配置 yum 源

vi /etc/yum.repos.d/gitlab-ce.repo

复制以下内容：

[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1

2.更新本地 yum 缓存

yum makecache

3.安装 GitLab 社区版

自动安装最新版：

yum install gitlab-ce

或下载安装包安装：

rpm -ivh gitlab-ce-15.4.2-ce.0.el7.x86_64.rpm

4.初始化

gitlab-ctl reconfigure

5.修改端口

vi /etc/gitlab/gitlab.rb

nginx['listen_port'] = 8000

vi  /var/opt/gitlab/nginx/conf/gitlab-http.conf

server {
  listen *:80;
  server_name 192.168.1.60;

修改完成后，执行：

gitlab-ctl reconfigure
gitlab-ctl restart

6.修改外部链接

vi /etc/gitlab/gitlab.rb

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

改为：

external_url '192.168.1.60'

7.查看版本号

cat /opt/gitlab/embedded/service/gitlab-rails/VERSION

8.登录

打开浏览器，输入 “http:/192.168.1.60”，进入登录页面：

默认账户名是 root，密码存放在配置文件：

/etc/gitlab/initial_root_password

该文件将在首次执行 reconfigure 后 24 小时自动删除，文件内容如下：

# WARNING: This value is valid only in the following conditions
#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.
#
#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

Password: /XhuNwa6xVjEMYmPthcOFUiaub/8bAWHn2C1jOFjrwI=

# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.

三、备份和恢复

1.备份

修改gitlab的备份路径：

vi /etc/gitlab/gitlab.rb

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

重启gitlab服务：

gitlab-ctl restart

备份命令：

gitlab-rake gitlab:backup:create

2.恢复

为保证数据的一致性先停止数据连接服务：

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

恢复（注意：不用带_gitlab_backup.tar后缀）：

gitlab-rake gitlab:backup:restore BACKUP=/var/opt/gitlab/backups/1575249855

启动刚才停的服务：

gitlab-ctl start unicorn
gitlab-ctl start sidekiq

或重启gitlab服务：

gitlab-ctl restart

四、卸载及重装

1.卸载

（1）停服务

gitlab-ctl stop

（2）卸载

yum remove gitlab-ce

或

rpm -qa|grep gitlab
rpm -e rpm -e gitlab-ce-15.4.2-ce.0.el7.x86_64.rpm

（3）杀进程

ps -ef|grep gitlab
kill xxx

（4）删文件

rm -rf /opt/gitlab/
rm -rf /var/log/gitlab/
rm -rf /var/opt/gitlab/

或

find / -name *gitlab*|xargs rm -rf

2.重装问题

（1）postgre 问题

卸载后重装，有时会报 postgre 错误：

data directory was initialized by PostgreSQL version 13, which is not compatible with this version 14.0

解决方法：
删除 postgre 相关目录后再重新安装：

rm -rf /opt/gitlab/
rm -rf /var/log/gitlab/
rm -rf /var/opt/gitlab/

或

find / -name *gitlab*|xargs rm -rf

（2）Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received ‘255’

执行 gitlab-ctl reconfigure 还可能出现以下错误：

Running handlers:

解决方法：

（3）Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received ‘1’

继续报错：

Running handlers:
There was an error running gitlab-ctl reconfigure:

chmod 0755 /var/opt/gitlab/postgresql
systemctl restart gitlab-runsvdir
#重启
gitlab-ctl reconfigure
gitlab-ctl restart

（4）ruby_block[wait for redis service socket] action run

执行 gitlab reconfigure 卡在 ruby_block[wait for redis service socket] action run。
解决方法：
执行命令：

systemctl start gitlab-runsvdir
