困扰我许久的问题终于解决了

一个是关机卡在mysql

sudo vim /etc/systemd/system/multi-user.target.wants/mysql.service

TimeoutSec=5

另一个是redis

sudo vim /etc/init.d/redis_6379

PASSWORD="1234qwer"

$CLIEXEC -p $REDISPORT -a $PASSWORD shutdown

又多了一个远程打印机

sudo systemctl disable cups-browsed.service

终于能正常关机了

It appears you can reduce the timeout in /etc/systemd/system.conf:

DefaultTimeoutStartSec=10sDefaultTimeoutStopSec=10s
