就一台测试环境有异常，并且该环境上dbus-broker服务也异常起不来。 nmcli报错的问题是由于dbus-broker服务异常导致。
经过分析，是测试环境执行了如下操作导致： dbus-daemon --config-file=/usr/share/dbus-1/system.conf --fork --print-address killall -9 dbus-daemon rm -rf /run/dbus/pid Anolis OS 23上默认的dbus服务是dbus-broker，默认场景下enabled的是dbus-broker，原先的anolis7/8上使用的dbus-daemon默认是disable。 执行上述dbus-daemon后破坏了系统dbus服务，从而导致一系列的异常。 可以先stop dbus-broker，再手动执行dbus-daemon，但是这也会导致dbus服务中断，上述命令执行完成后再启动dbus-broker服务，dbus服务中断还是会导致其他依赖dbus的服务异常，比如NetworkManager和firewalld，在重新启动dbus-broker后，需要重启这些受影响的服务。 建议对系统服务的测试，遵循系统服务的测试方法，比如服务起停，手动启动进程的方法需慎重。
