行不通勿喷，谢谢！！
**虚拟机部署gitlab 接口502 **
gitlab-ctl tail
查看具体报错信息：
==> /var/log/gitlab/nginx/gitlab_error.log <==
2023/09/04 16:45:44 [crit] 42817#0: *2 connect() to unix://var/opt/gitlab/gitlab-rails/sockets/gitlab.socket failed (13: Permission denied) while connecting to upstream, client: 192.168.0.110, server: 192.168.0.110, request: "GET / HTTP/1.1", upstream: "http://unix://var/opt/gitlab/gitlab-rails/sockets/gitlab.socket:/", host: "192.168.0.110:8090"
Nginx 在连接到上游服务器时出现了权限被拒绝的错误，
解决办法：给那个对应的文件加权限
chmod -R o+x /var/opt/gitlab/gitlab-rails/
已解决！！！！！！！！
前置错误！！
Linux下安装GitLab仓库，史上最详细的教程来啦~：https://blog.csdn.net/smilehappiness/article/details/106353324
1.安装各种教程安装后还是会502，各种解决方法都不行，一直502

后面自行使用nginx部署
实际上，这个快速部署的gitlab-ce软件包内是自带nginx的，然而实际服务器部署的话，我们常常需要部署在系统原生的nginx上，我们可以按照这样的方式进行操作：参考：https://www.cnblogs.com/HansBug/p/9813627.html
自行使用nginx部署后才是上面的报错信息，加权限后就可以了，网上教程都是基于这个！！！！！
gitlab如何查看初始化root密码
https://www.cnblogs.com/ianlab/p/17132228.html
密码要大于8位数：如果提示了以下内容，请重置密码为更复杂的
/opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activerecord-6.1.7.2/lib/active_record/validatio ns.rb:80:in
`raise_validation_error': Validation failed:
Password must not contain commonly us
ed combinations of words and letters (ActiveRecord::RecordInvalid)
