问题原因
在配置gitlab的过程中，本来想取消sign-up时，结果看错了，把sign-in的勾去掉了。导致退出之后无法登录
显示如下，不小心把这里的勾去掉了
再次登录提示如下
No authentication methods configured.
尝试的解决方法
1、前期不断试图从配置文件里找出相关的地方，最终没找到有用的配置
下面地方的配置都找过。尤其是gitlab.rb文件。找不到相关配置的地方

[root@linux-node2 etc]#
尝试修改文件/etc/gitlab/gitlab.rb，在最末尾添加如下，也不起作用
gitlab_rails['gitlab_signin_enabled'] = true
2、尝试卸载gitlab，然后重装
因为本来就是新装的测试环境，尝试卸载gitlab的rpm包，然后删除/opt/gitlab 和/etc/gitlab 目录，重装之后没效果，应该有还有一些目录没删除干净
尝试gitlab-ctl reconfigure 也不起作用
3、网上搜索
链接如下
https://www.libaocai.com/5727.html
解决步骤如下
gitlab-psql gitlabhq_production
UPDATE application_settings set signin_enabled=true;
\q
gitlab-ctl restart
操作过程如下
[root@linux-node1 etc]# gitlab-psql gitlabhq_production
could not change directory to "/var/opt/gitlab/gitlab-rails/etc": Permission denied
psql (9.6.1)
Type "help" for help. gitlabhq_production=# UPDATE application_settings set signin_enabled=true;
UPDATE 6
gitlabhq_production-# \q
