云服务器CentOS7安装gitlab

1. 安装4个相关依赖

yum -y install policycoreutils-python openssh-server openssh-clients postfix

查看是否安装成功

rpm -qa|grep openssh

rpm -qa|grep postfix

rpm -qa|grep policycoreutils-python

2. 启动postfix，并设置开机自启动

systemctl enable postfix

systemctl start postfix

启动时如果报错：Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.

vim /etc/postfix/main.cf

修改配置如下图

3. 配置ssh服务

systemctl enable sshd

systemctl start sshd

systemctl status sshd

防火墙的相关操作

systemctl status firewalld  查看防火墙有没有启动，没有就启动

将http服务策略添加到防火墙

firewall-cmd --permanent --add-service=http

firewall-cmd --permanent --add-service=https

systemctl status postfix  查看postfix有没有启动，没有就启动

4. 下载rpm包并安装

https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-13.1.2-ce.0.el7.x86_64.rpm

rpm -i gitlab-ce-13.1.2-ce.0.el7.x86_64.rpm

出现这个说明安装成功

5. 配置gitlab

vim /etc/gitlab/gitlab.rb

阿里云记得开放端口，防火墙也要开放

firewall-cmd --zone=public --add-port=端口号/tcp --permanent

改完后重置并启动gitlab

gitlab-ctl reconfigure

gitlab-ctl start

如果再次修改gitlab.rb配置，先停止  gitlab-ctl stop

并且修改后也要重置gitlab，gitlab-ctl reconfigure

再启动
