saltstack自动化运维系列⑩SaltStack二次开发初探

1、当salt运行在公网或者网络环境较差的条件下，需要配置timeout时间

vim /etc/salt/master

timeout: 60

2、salt-minion的单机模式：

修改配置文件：

# vim /etc/salt/minion

file_client: local

# /etc/init.d/salt-minion stop

本地命令测试

# salt-call --local test.ping

local:

True

# salt-call --local cmd.run 'df -Th'[INFO ] Executing command 'df -Th' in directory '/root'local:Filesystem Type Size Used Avail Use% Mounted on/dev/mapper/vg_node2-root ext4 29G 1.1G 27G 4% /tmpfs tmpfs 935M 0 935M 0% /dev/shm/dev/sda1 ext4 485M 39M 421M 9% /boot/dev/mapper/vg_node2-data ext4 29G 296M 28G 2% /data/dev/mapper/vg_node2-usr ext4 9.7G 2.1G 7.1G 23% /usr/dev/mapper/vg_node2-web ext4 25G 172M 23G 1% /web

 

# yum install python-setproctitle

该模块安装后可以通过ps更方便查看salt相关进程

ps aux | grep salt

3、简单二次开发

# mkdir /srv/salt/base/_grains

vim /srv/salt/base/_grains/my_grains.py

#!/usr/bin/env pythondef my_grains():'''my custom grains'''grains = {
   'mysite':'www.chinasoft.com','say':'life is short,i use python'}return grains

# salt '*' saltutil.sync_grains

mini1:

node2.chinasoft.com:

- grains.my_grains

# salt '*' grains.item mysite

node2.chinasoft.com:

----------

mysite:

www.chinasoft.com

mini1:

----------

mysite:

www.chinasoft.com

[root@mini1 ~]# salt '*' grains.item say

mini1:

----------

say:

life is short,i use python

node2.chinasoft.com:

----------

say:

life is short,i use python

编写模块

# mkdir /srv/salt/base/_modules

# vim /srv/salt/base/_modules/my_disk.py

def list():

cmd = 'df -Th'

ret = __salt__['cmd.run'](cmd)

return ret

应用模块

# salt '*' saltutil.sync_modules

使用查询：

# salt '*' my_disk.list

node2.chinasoft.com:Filesystem Type Size Used Avail Use% Mounted on/dev/mapper/vg_node2-root ext4 29G 1.1G 27G 4% /tmpfs tmpfs 935M 12K 935M 1% /dev/shm/dev/sda1 ext4 485M 39M 421M 9% /boot/dev/mapper/vg_node2-data ext4 29G 301M 28G 2% /data/dev/mapper/vg_node2-usr ext4 9.7G 2.1G 7.1G 23% /usr/dev/mapper/vg_node2-web ext4 25G 172M 23G 1% /webmini1:Filesystem Type Size Used Avail Use% Mounted on/dev/mapper/vg0-root ext4 25G 1.6G 23G 7% /tmpfs tmpfs 495M 16K 495M 1% /dev/shm/dev/sda1 ext4 291M 39M 238M 14% /boot/dev/mapper/vg0-usr ext4 20G 3.0G 16G 17% /usr/dev/mapper/vg0-var ext4 9.7G 1.1G 8.2G 11% /var

 

4、拷贝文件到所有minion客户端

# salt '*' webmin-1.831-1.noarch.rpm /data/webmin-1.831-1.noarch.rpm
