今天试着在centos7上安装了saltstack自动化运维工具，以下是安装步骤：


首先，我们安装bash-completion包，它可以补全centos7的命令。

yum install -y bash-completion


关于服务的启动问题：

首先，设置服务开机自动启动：

systemctl enable salt-master


查看是否设置好开机启动：

systemctl is-enabled salt-master


启动服务：

systemctl restart salt-master


查看服务状态：

[root@localhost ~]# systemctl status salt-master
