一、下载与安装

在主目录操作~
1.使用wget下载

wget --no-check-certificate https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-14.0.1-ce.0.el7.x86_64.rpm

可以在开源软件镜像站选择合适的版本，版本不同页面菜单会稍有差异，此次选择的是14.0.1，gitlab-ce-14.0.1-ce.0.el7.x86_64.rpm

 参考地址：Index of /gitlab-ce/yum/el7/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

 2.安装

rpm -i gitlab-ce-14.0.1-ce.0.el7.x86_64.rpm

安装成功样式

3.修改配置文件

vim  /etc/gitlab/gitlab.rb

 主要修改ip和port端口号，有域名直接填写域名，也可以写ip地址

4.重置gitlab

gitlab-ctl reconfigure

5.重启gitlab

gitlab-ctl start

二、打开浏览器访问
例如本地访问就是 http://47.97.159.12

此处设置root用户的密码，设置新密码，如果之前安装过其他版本，这里可能直接是登陆，可以用命令重置gitlab密码

sudo gitlab-rails console
 
user = User.where(id: 1).first
user.password = 'YOURPASSWORD'
user.password_confirmation = 'YOURPASSWORD'
user.save!

三、遇到的问题
1.安装gitlab
rpm -i gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm时出现这个错误，或者可安装其他版本

error: Failed dependencies: 	policycoreutils-python is needed by gitlab-ce-10.0.0-ce.0.el7.x86_64

解决

yum install policycoreutils-python

四、如果遇到管理员密码忘记的情况可重置换密码

五、卸载gitlab
卸载GitLab并重装：https://blog.csdn.net/jia12216/article/details/84853136

在服务器创建gitlab配置文件，/usr/local/nginx/conf/vhost，gitlab_nginx.conf

upstream gitlab-workhorse {
  server unix:/var/opt/gitlab/gitlab-workhorse/sockets/socket;
}

server
    {
        listen 80;
        #listen [::]:80;
        server_name IP地址或解析域名;
        server_tokens off;
        root /opt/gitlab/embedded/service/gitlab-rails/public;
        client_max_body_size 250m;

        location / {
            client_max_body_size 0;
            gzip off;

            ## https://github.com/gitlabhq/gitlabhq/issues/694
            ## Some requests take more than 30 seconds.
            proxy_read_timeout      300;
            proxy_connect_timeout   300;
            proxy_redirect          off;

            proxy_http_version 1.1;

            proxy_set_header    Host                $http_host;
            proxy_set_header    X-Real-IP           $remote_addr;
            proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
            proxy_set_header    X-Forwarded-Proto   $scheme;

            proxy_pass http://gitlab-workhorse;
          }
          location ~ ^/(assets)/  {
                root /opt/gitlab/embedded/service/gitlab-rails/public;
                # gzip_static on; # to serve pre-gzipped version
                expires max;
                add_header Cache-Control public;
          }
    }
