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]# ll /etc/gitlab/

[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
