本文主要是介绍saltstack执行模块，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
(1)master中编写自定义模块
[root@server1 ~]# mkdir /srv/salt/_modules -p
[root@server1 ~]# cd /srv/salt/_modules/
[root@server1 _modules]# vim my_disk.py
#!/use/bin/env python
def df():return __salt__['cmd.run']('df -h')刷新salt模块库
[root@server1 _modules]# salt '*' saltutil.sync_modules
server2:- modules.my_disk
server1:- modules.my_disk
server4:- modules.my_disk
server3:- modules.my_disk
推送自己的模块
[root@server1 _modules]# salt '*' my_disk.df
server3:Filesystem Size Used Avail Use% Mounted on/dev/mapper/VolGroup-lv_root 19G 1.1G 17G 6% /tmpfs 246M 16K 246M 1% /dev/shm/dev/vda1 485M 33M 427M 8% /boot
server4:Filesystem Size Used Avail Use% Mounted on/dev/mapper/VolGroup-lv_root 19G 1.1G 17G 6% /tmpfs 372M 16K 372M 1% /dev/shm/dev/vda1 485M 33M 427M 8% /boot
server2:Filesystem Size Used Avail Use% Mounted on/dev/mapper/VolGroup-lv_root 19G 990M 17G 6% /tmpfs 246M 96K 246M 1% /dev/shm/dev/vda1 485M 33M 427M 8% /boot
server1:Filesystem Size Used Avail Use% Mounted on/dev/mapper/VolGroup-lv_root 19G 1.1G 17G 7% /tmpfs 499M 76K 499M 1% /dev/shm/dev/vda1 485M 33M 427M 8% /boot
函数存放位置
[root@server4 ~]# cd /var/cache/salt
[root@server4 salt]# tree
.
`-- minion|-- accumulator|-- extmods| |-- grains| | |-- my_grains.py| | `-- my_grains.pyc| `-- modules #外部函数位置| |-- my_disk.py| `-- my_disk.pyc|-- files| `-- base| |-- _grains| | `-- my_grains.py| |-- haproxy| | |-- files| | | `-- haproxy.cfg| | `-- install.sls| |-- keepalived| | |-- files| | | |-- keepalived| | | |-- keepalived-2.0.6.tar.gz| | | `-- keepalived.conf| | |-- install.sls| | `-- service.sls| |-- _modules| | `-- my_disk.py| `-- top.sls|-- highstate.cache.p|-- module_refresh|-- pkg_refresh|-- proc`-- sls.p14 directories, 18 files
(2)salt中的常用模块ssh
<1>server4关闭salt-minion
<2>在server1上安装salt-ssh
[root@server1 ~]# yum install -y salt-ssh
<3>在server上编辑ssh的配置文件
[root@server1 ~]# vim /etc/salt/rosterserver3:host: 172.25.1.4 # 想要连接的主机user: root # 该主机的超级用户passwd: redhat # 该超级用户的密码
<4> 在server1中连通server4
salt-ssh 'server4' test.ping -i
<5>server1中执行命令,不启动minion
[root@server1 salt]# salt-ssh 'server4' cmd.run 'df -h'
server4:Filesystem Size Used Avail Use% Mounted on/dev/mapper/VolGroup-lv_root 14G 1.1G 12G 9% /tmpfs 499M 16K 499M 1% /dev/shm/dev/vda1 485M 33M 427M 8% /boot
(3) salt-syndic功能
<1> 选server4作为top master，关闭server4的minion,server1中去掉server4的minion
[root@server4 ~]# /etc/init.d/salt-minion stop[root@server4 ~]# chkconfig salt-minion off
<2> server4中安装salt-master
[root@server4 ~]# yum install salt-master
<3>修改sevrer4中master配置文件
vim /etc/salt/master
857 order_masters: True # 打开允许syndic功能
<4>server1中安装salt-syndic
[root@server1 ~]# yum install salt-syndic -y
[root@server1 ~]# vim /etc/salt/master
861 syndic_master: 172.25.1.4 # 设置top master为server4
[root@server1 ~]# /etc/init.d/salt-master restart
Stopping salt-master daemon: [确定]
Starting salt-master daemon: [确定]
[root@server1 ~]# /etc/init.d/salt-syndic start #需要启动syndic否则无法交换公钥
Starting salt-syndic daemon: [确定]<5> server4中发现server1
salt-key -A[root@server4 ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
server1
Rejected Keys:
[root@server4 ~]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
server1
Proceed? [n/Y] Y
Key for minion server1 accepted.
<6>sevrer4上执行推送，推送到了server1的各个minion端
[root@server4 ~]# salt '*' test.ping #在top master可以看到master管理的节点，减轻了master端的压力
server1:True
