SaltStack 之 快速安装

一、salt-master 安装（控制服务器）

1.下载异步的yum源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

2.通过yum源安装salt-master
yum -y install salt-master

3.设置salt-master的配置文件
vi /etc/salt/master

4.启动salt-master，并设置开机自启动
[[email protected] ~]# /etc/init.d/salt-master start
[[email protected] ~]# chkconfig sal-master on

二、salt-minion安装（被控制机器）

1.下载异步的yum源
[[email protected] ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

2.yum 安装salt-minion
[[email protected] ~]# yum -y install salt-minion 

3.修改salt-minion的配置文件，并指向master主机
[[email protected] ~]# vi /etc/salt/minion 

4.启动salt-minion，并设置开机自启动
[[email protected] ~]# /etc/init.d/salt-minion start
Starting salt-minion daemon: [确定]
[[email protected] ~]# chkconfig salt-minion on

三、检查从机是否与master主机互连

[[email protected] salt]# salt-key 
Accepted Keys:
Denied Keys:
Unaccepted Keys:
BackupServer                   #已发现从机：BackupServer
Rejected Keys:

[[email protected] salt]# salt-key -A       #允许所有主机加入控制
The following keys are going to be accepted:
Unaccepted Keys:
BackupServer
Proceed? [n/Y] y
Key for minion BackupServer accepted.
[[email protected] salt]# salt-key   
Accepted Keys:
BackupServer                 #已成功
Denied Keys:
Unaccepted Keys:
Rejected Keys:

[[email protected] ~]# salt ‘*‘ test.ping
BackupServer:
        True                    #通信正常

备注：salt ‘*‘ test.ping 解释

*: 代表目标，所有主机，如单台只填上id
test: 代表模块
ping: 代表方法

[[email protected] ~]# salt ‘BackupServer‘ cmd.run ‘df -h‘
BackupServer:
        Filesystem            Size  Used Avail Use% Mounted on
        /dev/sda3              95G  6.8G   83G   8% /
        tmpfs                 5.9G   12K  5.9G   1% /dev/shm
        /dev/sda1             190M  103M   78M  57% /boot
        /dev/mapper/vg-data    99G  1.3G   93G   2% /app
        /dev/mapper/vg_server-backup
                                                    1.3T  798G  440G  65% /backup
