gitlab是一个基于git实现的在线代码仓库托管软件，一般用于在企业、学校等内部网络搭建专属git仓库，越来越多的企业在使用gitlab作为项目托管仓库。

一、安装配置依赖

1、安装启动ssh服务

sudo yum install -y curl policycoreutils-python openssh-server #安装ssh
sudo systemctl enable sshd  #开机自启
sudo systemctl start sshd   #启动ssh

2、配置防火墙

sudo firewall-cmd --state #查看防火墙状态
sudo systemctl start firewalld #没有启动，可以启动防火墙
sudo firewall-cmd --permanent --add-service=http #添加防火墙支持http永久访问
sudo systemctl reload firewalld  #重新加载防火漆配置

3、安装邮件服务

sudo yum install postfix -y   #安装postfix
sudo systemctl enable postfix  #开机自启
sudo systemctl start postfix  #启动postfix

二、安装配置gitlib

1. 配置yum源

#下载此脚本并运行，会自动下载当前系统的yum源，/etc/yum.repos.d/gitlab_gitlab-ee.repo
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash

可以看到已经下载了yum源：gitlab_gitlab-ee.repo

[root@localhost software]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-Media.repo    CentOS-Vault.repo
CentOS-CR.repo    CentOS-fasttrack.repo  CentOS-Sources.repo  gitlab_gitlab-ee.repo

国外镜像安装时十分慢，可以把刚下载的gitlab_gitlab-ee.repo删除掉

再把yum换成清华的镜像https://mirror.tuna.tsinghua.edu.cn/help/gitlab-ce/

新建源：vim /etc/yum.repos.d/gitlab-ce.repo，内容如下

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

2、yum开始安装

#刷新yum缓存
sudo yum makecache
#安装
sudo yum install -y gitlab-ee

看到如下表示安装成功

Installed:
  gitlab-ce.x86_64 0:11.4.0-ce.0.el7                                                                                                  

Complete!

3、配置访问地址

vim /etc/gitlab/gitlab.rb，修改external_url，邮件配置参考https://docs.gitlab.com/omnibus/settings/smtp.html

#其他默认不变，如果需要用到的功能可以参考资料配置
external_url 'http://192.168.172.74:8081'

发送邮件配置
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "mail.ultrapower.com.cn"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "[email protected]"
gitlab_rails['smtp_password'] = "12333lzxcl"
gitlab_rails['smtp_domain'] = "ultrapower.com.cn"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = false
gitlab_rails['gitlab_email_from'] = '[email protected]'
gitlab_rails['gitlab_email_reply_to'] = '[email protected]'

命令测试：gitlab-rails console，以下表示成功

4、重新配置应用

gitlab-ctl reconfigure #此命令同时已经启动gitlab所有服务

5、启动gitlab

gitlab-ctl status #查看是否启动
gitlab-ctl start  #没有启动可以启动
gitlab-ctl restart #重新启动下
gitlab-ctl stop #停止
gitlab-ctl --help #查看更多命令

6、防火墙开放端口

firewall-cmd --zone=public --list-ports #查看开放端口
firewall-cmd --zone=public --add-port=8081/tcp --permanent #开放8081端口
firewall-cmd --reload   #重新加载配置
#如果不需要，也可以直接关闭防火墙
systemctl stop firewalld.service
