1、下载
使用yum方式即可，可以更换下yum源，这里使用的阿里云的
[root@salt-master ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum -y install epel-release
yum clean all
yum makecache
yum -y install salt-master salt-minion
2、设置开机自启动服务
systemctl enable salt-minion.service
systemctl enable salt-master.service
这里我在一台机器上安装了一个master和一个minion
3、启动服务
systemctl start salt-master.service
systemctl start salt-minion.service
4、关闭防火墙
systemctl disable firewalld.service
setenforce
5、查看是否认证成功
修改master和minion端的配置文件，这里直接使用sed修改
sed -i 's/#interface: 0.0.0.0/interface: 192.168.235.133/g' /etc/salt/master
sed -i 's/#master/master: 192.168.235.133/g' /etc/salt/minion
sed -i 's/#id/id: m1/g' /etc/salt/minion
修改完成后需要重启下服务，然后再来验证是否认证成功
[root@localhost ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
m1
Rejected Keys:
[root@localhost ~]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
m1
Proceed? [n/Y] y
Key for minion m1 accepted.
[root@localhost ~]# salt-key
Accepted Keys:
m1
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[root@localhost ~]# salt m1 test.ping
m1:
True
