在 CentOS 上安装 iRedMail 后无法启动任何服务

我尝试在一台服务器上安装 iRedMail。重启后，我无法再启动任何服务。

[root@mx ~]# systemctl start httpd

[root@mx ~]#

有人知道该如何解决这个问题吗？

更新 重新安装并启动 polkit 后得到了以下信息：

[root@mx ~]# systemctl start polkit

这看起来就像是软件包安装过程中删除了一些重要的东西。错误与策略工具包有关。您能确认 polkit 和 dbus 都还安装着吗rpm -qi dbus？rpm -qi polkit

日志也可能包含信息，但这里似乎有一个策略由于 dbus 没有响应而阻止这些服务的启动...因为 dbus 未安装或策略套件未通过 dbus 响应。

也可能是 SElinux 的责任...您可以通过编辑来禁用测试： /etc/sysconfig/selinux然后注销并重新登录。

如果您发现 selinux 负责策略，则可以使用以下命令显示： getsebool -a | grep disable.*on 并进行如下设置： setsebool httpd_disable_trans 1
