– Subject: Unit salt-master.service has failed
– Defined-By: systemd

解决办法：
根据提示可以看到报错：ImportError: libzmq.so.5: cannot open shared object file: No such file or directory
所以：
http://rpmfind.net/linux/RPM/epel/7/x86_64/Packages/z/zeromq-4.1.4-6.el7.x86_64.html

[[email protected] salt]# yum install zeromq-4.1.4-6.el7.x86_64.rpm
再次启动服务，无报错，问题解决！
