三种模式
Local
Master/minion
Salt ssh
三大功能
远程执行
配置管理
云管理
配置系统环境
cat /etc/redhat-release
CentOS release 6.6 (Final)
setenforce 0
/etc/init.d/iptables stop
[[email protected] ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.129node1

[[email protected] ~]# cat /etc/hosts

下载并配置slat-master 和salt-minion（Master/minion模式）
[[email protected] ~]# wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-6.repo
[[email protected] ~]# yum install -y salt-master salt-minion -y
[[email protected] ~]# chkconfig salt-master on
[[email protected] ~]# /etc/init.d/salt-master start
[[email protected] ~]# vim /etc/salt/minion
master: 192.168.10.129
[[email protected] ~]# /etc/init.d/salt-minion start
[[email protected] ~]# chkconfig salt-minion on
[[email protected] ~]# wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-6.repo
[[email protected] ~]# yum install -y salt-minion
[[email protected] ~]# vim /etc/salt/minion
master: 192.168.10.129
[[email protected] ~]# /etc/init.d/salt-minion start
Master与Minion的连接
[[email protected] master]# salt-key -a node*
[[email protected] master]# salt-key -L
Accepted Keys:
node1
node2
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[[email protected] master]# salt ‘*‘ test.ping
node2:
True
node1:
True
远程执行命令
[[email protected] master]# salt ‘*‘ cmd.run ‘df -h‘
node1:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
8.3G 2.1G 5.8G 26% /
tmpfs 242M 16K 242M 1% /dev/shm
/dev/sda1 477M 28M 424M 7% /boot
node2:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
8.3G 2.1G 5.9G 26% /
tmpfs 242M 12K 242M 1% /dev/shm
/dev/sda1 477M 28M 424M 7% /boot
[[email protected] master]# salt ‘*‘ cmd.run ‘uptime‘
node2:
13:33:55 up 13:51, 2 users, load average: 0.07, 0.02, 0.00
node1:
05:35:41 up 13:51, 2 users, load average: 0.00, 0.04, 0.10
配置管理（下载httpd并启动）
[[email protected] master]# vim /etc/salt/master （注意空格，必须要启动一个base才能配置管理）
file_roots:
base:
- /srv/salt
[[email protected] master]# mkdir /srv/salt
[[email protected] master]# /etc/init.d/salt-master restart
[[email protected] master]# cd /srv/salt/
[[email protected] salt]# cat apache.sls(注意空格)
apache-install:
pkg.installed:
- names:
- httpd
- httpd-devel
apache-service:
service.running:
- name: httpd
- enable: True
- reload: True
使用命令直接执行状态
[[email protected] salt]# salt ‘*‘ state.sls apache（*代表所有salt-minion都执行）
[[email protected] ~]# netstat -tunlp|grep httpd
tcp 0 0 :::80 :::* LISTEN 9361/httpd
[[email protected] salt]# netstat -tunlp|grep 80
tcp 0 0 :::80 :::* LISTEN 23119/httpd
使用top.sls指定minlion执行状态
[[email protected] salt]# pwd
/srv/salt
[[email protected] salt]# cat top.sls(base环境下指定node2要执行apache这个状态,top指定谁可以执行什么状态，一般所有机器要执行的状态放在base环境中)
base:
‘node2‘ :仅仅node2执行了apache这个状态
- apache
[[email protected] salt]# salt ‘node2‘ state.highstate
