卸载DCOS

再次安装，已经是隔了两天，我打算换一台机器作为boot机器，但是发现报错，告知部署设备已经安装了dcos；看来需要卸载：
uninstall-master.sh

 /opt/mesosphere/bin/pkgpanda uninstall && \
 rm -rf /opt/mesosphere /var/lib/mesos /var/lib/dcos /var/lib/zookeeper /var/log/mesos /etc/mesosphere /var/lib/mesosphere && \
 rm -rf /etc/profile.d/dcos.sh /etc/systemd/journald.conf.d/dcos.conf /etc/systemd/system/dcos-cfn-signal.service /etc/systemd/system/dcos-download.service /etc/systemd/system/dcos-link-env.service /etc/systemd/system/dcos-setup.service /etc/systemd/system/multi-user.target.wants/dcos-setup.service /etc/systemd/system/multi-user.target.wants/dcos.target

uninstall-agent.sh

 echo '+++uninstall starting...+++'
 echo ''
 systemctl kill -s SIGUSR1 dcos-mesos-slave;
 sudo -i  /opt/mesosphere/bin/pkgpanda uninstall;

 systemctl stop dcos-adminrouter-agent.service;
 systemctl stop dcos-diagnostics.service;
 systemctl stop dcos-epmd.service;

 sudo rm -rf /opt/mesosphere /etc/mesosphere;
 sudo rm -rf /opt/dcos-prereqs.installed;
 sudo rm -rf /var/lib/dcos;
 sudo rm -rf /var/lib/mesos;
 sudo rm -rf /etc/systemd/system/dcos-*;
 sudo rm -rf /etc/systemd/system/dcos.target /etc/systemd/system/dcos.target.wants;
 sudo rm -rf /run/dcos
 echo ''
 echo '+++uninstall complete+++'

　　这里记录一下，因为rm
-rf
后面没有加绝对路径（直接写的文件名字），而导致dcos.target以及docs.target.wants没有删除掉，于是多次尝试删除重建失败，就是提示我没有删除干净，想想也是醉了。知道一次无意间的到/etc/systemd/system/下面，才发现还有这两个漏网之鱼。浪费了的一个下午啊。
