利器：大规模集群管理工具——saltstack

主机准备

虚拟机两台

[root@saltmaster ~]# hostname -I
192.168.60.120
[root@saltminion ~]# hostname -I
192.168.60.121

软件安装

服务端安装salt-master和salt-minion
客户端只安装salt-minion，不安装salt-master

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install -y epel-release
yum install -y salt-master salt-minion

服务配置

服务端

#配置自动接收认证
sed -i 's/#auto_accept: False/auto_accept: True/g' /etc/salt/master
#指定master
sed -i 's/#master: salt/master: 192.168.60.120/g' /etc/salt/minion

客户端

#指定master
sed -i 's/#master: salt/master: 192.168.60.120/g' /etc/salt/minion

启动

服务端

systemctl restart salt-master.service
systemctl status salt-master.service
systemctl enable salt-master.service

客户端

systemctl restart salt-minion
systemctl enable salt-minion
systemctl status salt-minion

验证

[root@saltmaster ~]# salt '*' test.ping
saltminion:
    True
saltmaster:
    True
[root@saltmaster ~]# salt '*' cmd.run   'df -h'
