CentOS 7.2 部署Saltstack-Elephant
CentOS 7.2部署Saltstack一、环境介绍：
服务器名称IP地址Salt-Master192.168.30.141Slave1192.168.30.131Slave2192.168.30.132 二、部署前的准备：
1、添加host文件：
在Master上操作：
# echo -e "192.168.30.141 Salt-Master\n192.168.30.131 Slave1\n192.168.30.132 Slave2" >> /etc/hosts
# sed -i "s/HOSTNAME=.*/HOSTNAME=Salt-Master/g" /etc/sysconfig/network
# hostname Salt-Master
在Slave1上操作
# echo -e "192.168.30.141 Salt-Master\n192.168.30.131 Slave1\n192.168.30.132 Slave2" >> /etc/hosts
# sed -i "s/HOSTNAME=.*/HOSTNAME=Slave1/g" /etc/sysconfig/network
# hostname Slave1
在Slave2上操作
# echo -e "192.168.30.141 Salt-Master\n192.168.30.131 Slave1\n192.168.30.132 Slave2" >> /etc/hosts
# sed -i "s/HOSTNAME=.*/HOSTNAME=Slave2/g" /etc/sysconfig/network
# hostname Slave2
2、安装编译环境(三台机器都要安装):
# yum -y install gcc-c++
# yum -y install epel-release
3、安装Saltstack源(三台机器都要安装):
# yum install https://repo.saltstack.com/yum/redhat/salt-repo-latest-1.el7.noarch.rpm
# yum clean expire-cache
三、安装部署Saltstack：
服务端安装（Master）：
# yum -y install salt-master
修改配置文件：
# sed -i 's/#interface:.*/interface:192.168.30.141/g' /etc/salt/master #修改master监控的IP地址（即本机IP）
# sed -i 's/#auto_accept:.*/auto_accept: True/g' /etc/salt/master #修改签证为自动签证
# egrep -v "^#|^$" /etc/salt/master
interface: 192.168.30.141
auto_accept: True
启动Master服务：
# systemctl start salt-master
# systemctl stop firewalld.servcie #本文为做实验方便，关闭firewall；在正常生产环境中建议开启
客户端部署（Minion）:
# yum -y install salt-minion
修改配置文件：
# sed -i 's/#master:.*/master: 192.168.30.141/g' /etc/salt/minion # 指定Master主机
此项为自定义主机ID（自选）：
# sed -i 's/#id:.*/id: Server1/g' /etc/salt/minion
# egrep -v "^#|^$" /etc/salt/minion
master: 192.168.30.141
id: Server1
启动Minion服务：
# systemctl start salt-minion
# netstat -an|egrep '4505|4506'
tcp 0 0 192.168.30.131:58706 192.168.30.141:4505 ESTABLISHED
tcp 0 0 192.168.30.131:60583 192.168.30.141:4506 ESTABLISHED
tcp 0 0 192.168.30.131:60585 192.168.30.141:4506 TIME_WAIT
tcp 0 0 192.168.30.131:60586 192.168.30.141:4506 TIME_WAIT
#Slave2的操作与Slave1的部署一样，在此就不多做示范了！
四、测试
在服务端（Master）操作：
# salt-key -L #查看已经签证的Minion节点
Accepted Keys:
Slave1
Slave2
Denied Keys:
Unaccepted Keys:
Rejected Keys:
# salt '*' cmd.run "uptime" #获取所有Minion节点的uptime时间
Slave1:
03:44:55 up 17:47, 2 users, load average: 0.00, 0.00, 0.00
Slave2:
19:04:05 up 1 day, 10:13, 2 users, load average: 0.00, 0.00, 0.00
至此Saltstack的部署就已经部署完毕了，详细参考手册见：http://zlyang.blog.51cto.com/1196234/1854835
