安装Gitlab
准备工作：
- 安装之前硬盘可用空间建议10G以上，否则可能碰到因空间不足导致安装、配置问题。
- 关闭防火墙 systemctl stop firewalld.service
安装依赖
yum -y install epel-release curl openssh-server openssh-clients postfix cronie policycoreutils-python
下载安装包(centos6.x=el6, centos7.x=el7, centos8.x=el8按需选择)
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-13.1.2-ce.0.el7.x86_64.rpm --no-check-certificate
安装
rpm -ivh gitlab-ce-13.1.2-ce.0.el7.x86_64.rpm
配置Gitlab
修改配置文件：vi /etc/gitlab/gitlab.rb
external_url 'http://192.168.200.100:8081'
重新加载配置文件
gitlab-ctl reconfigure
启动并检查运行状态
启动gitlab
gitlab-ctl start
正常运行后启动了很多进程和端口，其中8081是gitlab对外访问的端口

错误锦集
gitlab安装完后执行gitlab-ctl reconfigure时卡在
ruby_block[wait for redis service socket] action run
解决方法：
另起shell终端执行该命令，或先执行该命令再重新执行gitlab-ctl reconfigure
systemctl start gitlab-runsvdir
GitLab 报错 ConnectionBad: could not connect to server: No such...
解决方法：
1、按住CTRL+C强制结束
2、先停止 gitlab ，命令： sudo gitlab-ctl stop
3、执行命令： sudo chmod 755 /var/opt/gitlab/postgresql
4、执行命令：sudo systemctl restart gitlab-runsvdir
5、再次配置：sudo gitlab-ctl reconfigure
6、启动即可：sudo gitlab-ctl restart
502, whoops, gitlab is taking too much time to respond
原因：8080端口被占用，修改端口号并重启
随便修改成一个不会被占用的端口
unicorn['port'] = 8088
打开注释
postgresql['shared_buffers'] = "256MB"
打开注释
postgresql['max_connections'] = 200
gitlab常用命令
gitlab-ctl start # 启动所有 gitlab 组件；
gitlab-ctl stop # 停止所有 gitlab 组件；
gitlab-ctl restart # 重启所有 gitlab 组件；
gitlab-ctl status # 查看服务状态；
gitlab-ctl reconfigure # 重新加载配置并启动服务；
gitlab-ctl tail # 查看日志；
systemctl enable gitlab-runsvdir.service #开机启动
systemctl disable gitlab-runsvdir.service #禁开机启动
