配置管理工具Saltstack 之 自定义grains

salt master配置

# cat /etc/salt/master|grep -v ‘#‘

interface: 192.168.xxx.xxx

worker_threads: 15
auto_accept: True
file_roots:
  base:
    - /data/salt/base

自定义grains有两种方法,第一种minion端配置，但是需要重启minion生效；第二种在master端配置，同步之后生效，不需要重启master或者minion

本例以第二种方法master端自定义grains

在salt base (/data/salt/base)目录下创建_grains目录，在 _grains目录下nginx.py

#!/usr/bin/env python
#coding:utf-8
#定义nginx配置文件、日志等信息

import os,commands
def nginx():
  grains = {}
  grains[‘nginx_bin‘] = commands.getoutput("ps -ef | grep nginx  |grep master| grep -v grep |awk ‘{print $(NF-2)}‘").split(‘\n‘)
  grains[‘nginx_conf‘] = commands.getoutput("ps -ef |grep nginx |grep master | grep -v grep |awk ‘{print $(NF)}‘").split(‘\n‘)
  nginx_dir = []
  nginx_log = []
  for files in grains[‘nginx_bin‘]:
      nginx_dir.append(os.path.dirname(os.path.dirname(files)))
      nginx_log.append(os.path.dirname(os.path.dirname(files)) + ‘/logs/access.log‘)
  grains[‘nginx_dir‘] = nginx_dir
  grains[‘nginx_log‘] = nginx_log
  return grains

if __name__ == ‘__main__‘:
    nginx()

同步并查看定义的grains信息

# salt 192.168.xxx.xxx saltutil.sync_grains
192.168.xxx.xxx:
    - grains.nginx

# salt 192.168.xxx.xxx grains.item nginx_conf nginx_log nginx_bin
192.168.xxx.xxx:
    ----------
    nginx_bin:
        - /data/PRG/nginx-magicube/sbin/nginx
        - /data/PRG/tengine-play10/sbin/nginx
    nginx_conf:
        - /data/PRG/nginx-magicube/conf/nginx.conf
        - /data/PRG/tengine-play10/conf/nginx.conf
    nginx_log:
        - /data/PRG/nginx-magicube/logs/access.log
        - /data/PRG/tengine-play10/logs/access.log

可以看到定义的grains.nginx项已经生效
