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
1 /opt/mesosphere/bin/pkgpanda uninstall && 2 rm -rf /opt/mesosphere /var/lib/mesos /var/lib/dcos /var/lib/zookeeper /var/log/mesos /etc/mesosphere /var/lib/mesosphere && 3 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

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。
