尝试 1：
(rt5venv) root@devrt5:/etc/apache2/sites-available# systemctl status apache2
或者journalctl -xe：

RT couldn't connect to the database where tickets are stored.
If this is a new installation of RT, you should visit the URL below
to configure RT and initialize your database.
If this is an existing RT installation, this may indicate a database
connectivity problem.
当尝试连接数据库时，RT 返回的错误是：
Connect Failed Access denied for user 'rt_user'@'localhost' (using password: YES)
at /opt/rt5/sbin/../lib/RT.pm line 222.
我还做了以下事情：
rt5.*授予使用选项rt_user@localhost的所有权限grant。- 设置密码以及
rt_user数据库的密码rt_siteconfig.pm。
我可以使用 MySQLmysql -u root -p并且它运行良好。
如果需要，我很乐意提供有关文件信息的更多详细信息。
