salt master配置

# cat /etc/salt/master|grep -v '#'interface: 192.168.xxx.xxxworker_threads: 15auto_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,commandsdef 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 grainsif __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_bin192.168.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
