一、访问gitlab登录页面报500错误
1. 查看tail -f /var/log/gitlab/gitlab-rails/production.log有以下报错
NoMethodError (undefined method `login_recaptcha_protection_enabled' for #<ApplicationSetting:0x00007fdc026a3f70>
Did you mean? recaptcha_or_login_protection_enabled):
2. 查看服务运行情况，全部正常
[root@gitlab ~]# gitlab-ctl status
run: alertmanager: (pid 5120) 32885s; run: log: (pid 3362) 33748s
run: gitaly: (pid 5130) 32884s; run: log: (pid 2767) 33850s

3. 查看数据库状态，发现有两个处于down状态（ps：GitLab发现报500错误，大部分因为DB数据关系错误，需要升级数据库关系）
[root@gitlab ~]# gitlab-rake db:migrate:status
down 20190719122333 Add login recaptcha protection enabled to application settings
down 20190816151221 Add active jobs limit to plans
#第一个的作用：向应用程序设置中添加已启用的登录recaptcha保护
#第二个的作用：将活动工作限制添加到计划中
注意：这里数据库出现这种情况的原因是gitlab汉化导致的
4. 更新数据库关系
[root@gitlab ~]# gitlab-rake db:migrate
浏览器访问登录页面（gitlab.xiaoyu.com）
问题解决
