一、下载gitlab软件

1、通过国内资源（清华镜像）进行下载，地址为https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/。

通过yum仓库进行安装.png

二、安装gitlab

通过yum仓库进行安装

这种方式如截图所示：
1、添加gitlab到yum仓库中：
curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
2、通过yum进行安装：
sudo yum install gitlab-ce-14.7.6-ce.0.el7.x86_64
如果是root用户，可以删除sudo
yum install gitlab-ce-14.7.6-ce.0.el7.x86_64

通过源码包进行安装

1、将文件通过scp命令传输到服务器中
scp gitlab-ce-14.7.6-ce.0.el7.x86_64.rpm root@192.168.10.150:/root/Downloads
2、安装相关依赖
yum -y install policycoreutils openssh-server openssh-clients postfix
3、开启postfix，支持gitlab邮件发送
systemctl start postfix
设置开机自启动：
systemctl enable postfix
4、安装gitlab
rpm -ivh gitlab-ce-14.7.6-ce.0.el7.x86_64.rpm

安装完成截图

gitlab-ctl reconfigure # 重置
gitlab-ctl restart # 重启

reconfigure成功截图.png

restart成功截图.png

7、gitlab初始密码：
初始密码存放在/etc/gitlab/initial_root_password
该密码在首次执行reconfigure24小时候自动删除。

问题合集

问题一：缺少依赖

问题二：软件包下载失败

失败截图

解决方案：可能是由于网络原因下载失败，重新下载即可。

问题三：安装后没有设置自动重启，就把虚拟机给关闭了，再次打开虚拟机时，gitlab没有启动。

重启虚拟机后，gitlab启动失败

解决方案：

# 1、先启动对应的服务
systemctl start gitlab-runsvdir
# 2、通过gitlab-ctl重启gitlab
gitlab-ctl restart

成功截图

成功安装gitlab后，通过浏览器访问出现502

502错误

这个也没有弄懂为什么，我是通过修改端口后就可以了

# 修改对应的端口号为非常用的，如8081
vim /etc/gitlab/gitlab.rb 
# gitlab-ctl reconfigure
# gitlab-ctl restart

控制性信息

浏览器访问

root密码忘记

解决方案：
1、查看用户的id

curl http://gitlab的url/api/v4/users?username=root

查询用户id

通过上述命令无法进入gitlab的控制台，后来又试了一种
gitlab-rails console -e production
成功进入（ps：在gitlab官网找到对应版本的命令，但是我没有找到，有人找到麻烦留个言或者私信一下）

user = User.where(id: 1).first # 根据id找到用户
user.password = 'learngitlab' # 设置用户密码
user.password_confirmation = 'learngitlab' # 确认密码
user.save! # 保存密码
quit # 退出控制台
