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
[root@node1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.129node1
192.168.10.128 node2
[root@node2 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.129  node1
192.168.10.128 node2

下载并配置slat-master 和salt-minion（Master/minion模式）

[root@node1 ~]# wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-6.repo
[root@node1 ~]# yum install -y salt-master salt-minion -y
[root@node1 ~]# chkconfig salt-master on
[root@node1 ~]# /etc/init.d/salt-master start[root@node1 ~]# vim /etc/salt/minion
master: 192.168.10.129
[root@node1 ~]# /etc/init.d/salt-minion start
[root@node1 ~]# chkconfig salt-minion on[root@node2 ~]# wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-6.repo
[root@node2 ~]# yum install -y salt-minion
[root@node2 ~]# vim /etc/salt/minion
master: 192.168.10.129
[root@node2 ~]# /etc/init.d/salt-minion start

Master与Minion的连接

[root@node1 master]# salt-key -a node*
[root@node1 master]# salt-key -L
Accepted Keys:
node1
node2
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[root@node1 master]# salt '*' test.ping
node2:True
node1:
True

远程执行命令

[root@node1 master]# salt '*' cmd.run 'df -h'
node1:Filesystem            Size  Used Avail Use% Mounted on/dev/mapper/VolGroup-lv_root8.3G  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_root8.3G  2.1G  5.9G  26% /tmpfs                 242M   12K  242M   1% /dev/shm/dev/sda1             477M   28M  424M   7% /boot
[root@node1 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）

[root@node1 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
[root@node1 master]# mkdir /srv/salt
[root@node1 master]# /etc/init.d/salt-master restart
[root@node1 master]# cd /srv/salt/
[root@node1 salt]# cat apache.sls    #注意空格
apache-install:pkg.installed:- names:- httpd- httpd-develapache-service:service.running:- name: httpd- enable: True
- reload: True

使用命令直接执行状态

[root@node1 salt]# salt '*' state.sls apache    #*代表所有salt-minion都执行
[root@node2 ~]# netstat -tunlp|grep httpd
tcp        0      0 :::80                       :::*                        LISTEN      9361/httpd
[root@node1 salt]# netstat -tunlp|grep 80
tcp        0      0 :::80                       :::*                        LISTEN      23119/httpd

使用top.sls指定minlion执行状态

[root@node1 salt]# pwd
/srv/salt
[root@node1 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[root@node1 salt]# salt 'node2' state.highstate
