1. GitLab-Shell仍然需要正确配置才能访问GitLab，否则你在远端用git协议pull的时候会看到错误信息：

    http.use_ssl = (url.scheme == 'https')

    if config.http_settings['self_signed_cert'] && http.use_ssl?
      http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    end

1.self_signed_cert设置为true

2.url要用https

回到config.yml文件中，这样配置：

# Url to gitlab instance. Used for api calls. Should be ends with slash.                                                                                                                                             
gitlab_url: "https://localhost/"

http_settings:
#  user: someone                                                                                                                                                                                                     
#  password: somepass                                                                                                                                                                                                
  self_signed_cert: true

2. 重启时老看到这个错误：

1.先用ps-def | grep gitlab 命令找到还运行的进程id，然后kill -9 干掉

2.删除下面的文件

/home/git/gitlab/tmp/sockets/gitlab.socket

现在启动，应该可以了。
