Saltstack配置管理-给minion增加Zabbix-agent

zabbix-agent的包

[root@A ~]# rpm -qa |grep zabbix
zabbix-2.4.8-1.el6.x86_64
zabbix-web-2.4.8-1.el6.noarch
zabbix-web-mysql-2.4.8-1.el6.noarch
zabbix-server-mysql-2.4.8-1.el6.x86_64
zabbix-server-2.4.8-1.el6.x86_64
zabbix-agent-2.4.8-1.el6.x86_64
zabbix-get-2.4.8-1.el6.x86_64
zabbix-release-2.4-1.el6.noarch
[root@A ~]#

因为我们想让一个系统在配置业务之前就让它被监控到，因此写的配置zabbix的状态文件应该放到系统初始化里面的

可以看到配置文件使用了jinja模板，把变量提取出来。可以这么理解，Server后面就是10.0.1.161， 而这个10.0.1.161是通过pillar获取的，pillar文件在/srv/salt/pillar文件里

[root@master prod]# cd /srv/salt/base/init/
[root@master init]# ls
audit.sls  dns.sls  env_init.sls  files  history.sls  sysctl.sls
[root@master init]# vim zabbix_agent.sls
[root@master init]# cat zabbix_agent.sls
zabbix-agent-install:
  pkg.installed:
    - name: zabbix-agent
  file.managed:
    - name: /etc/zabbix/zabbix_agentd.conf
    - source: salt://init/files/zabbix_agentd.conf
    - template: jinja
    - defaults:
      Server: {{ pillar['zabbix-agent']['Zabbix-Server'] }}
    - require:
      - pkg: zabbix-agent-install
  service.running:
    - name: zabbix-agent
    - enable: True
    - watch:
      - pkg: zabbix-agent-install
      - file: zabbix-agent-install
[root@master init]#

上面内容用到了pillar

目前还没有pillar，执行肯定会报错
下面这个是个两级的key

pillar['zabbix-agent']['Zabbix-Server']

对pillar进行管理

vim /etc/salt/master

pillar_roots:
  base:
    - /srv/pillar/base

重启服务，建立pillar的基础目录

[root@master init]# vim /etc/salt/master
[root@master init]# /etc/init.d/salt-master restart
Stopping salt-master daemon:                               [  OK  ]
Starting salt-master daemon:                               [  OK  ]
[root@master init]# mkdir /srv/pillar/base  -p
[root@master init]#

建立zabbix相关的pillar配置

[root@master base]# cd /srv/pillar/base/
[root@master base]# cat zabbix.sls
zabbix-agent:
  Zabbix-Server: 10.0.1.161
[root@master base]# cat top.sls
base:
  '*':
    - zabbix
[root@master base]#

把现网zabbix-agent文件传输到master机器上

我本地有个10.0.1.161机器安装了zabbix-agent

[root@A ~]# ll /etc/zabbix/
total 32
drwxr-x---. 2 apache apache  4096 Nov 29 05:55 web
-rw-r--r--. 1 root   root    7905 Nov 29 05:59 zabbix_agentd.conf
drwxr-xr-x. 2 root   root    4096 Nov 29 03:13 zabbix_agentd.d
-rw-r-----. 1 root   zabbix 13545 Nov 29 05:45 zabbix_server.conf
[root@A ~]# nc -l 18080 < /etc/zabbix/zabbix_agentd.conf
[root@A ~]#

master机器获取zabbix-agent的配置文件

[root@master base]# cd /srv/salt/base/init/files/
[root@master files]# nc 10.0.1.161 18080 > zabbix_agentd.conf
[root@master files]#

修改此配置文件，把变量的值替换为一个jinja模板形式的变量

[root@master files]# grep Server=  zabbix_agentd.conf
# Server=
Server=10.0.1.161
[root@master files]# grep ^Server=  zabbix_agentd.conf
Server=10.0.1.161
[root@master files]# grep 10.0.1.161  zabbix_agentd.conf
Server=10.0.1.161
[root@master files]# sed -i 's#10.0.1.161#{{ Server }}#g' zabbix_agentd.conf
[root@master files]# grep ^Server=  zabbix_agentd.conf
Server={{ Server }}
[root@master files]#

刷新pillar信息，尝试是否可以获取

这里用到了pillar.get模块

[root@master files]# salt '*' saltutil.refresh_pillar
minion02:
    True
minion01:
    True
[root@master files]# salt '*'  pillar.items
minion01:
    ----------
    zabbix-agent:
        ----------
        Zabbix-Server:
            10.0.1.161
minion02:
    ----------
    zabbix-agent:
        ----------
        Zabbix-Server:
            10.0.1.161
[root@master files]# salt '*'  pillar.get zabbix-agent
minion02:
    ----------
    Zabbix-Server:
        10.0.1.161
minion01:
    ----------
    Zabbix-Server:
        10.0.1.161
[root@master files]# salt '*'  pillar.get zabbix-agent:Zabbix-Server
minion01:
    10.0.1.161
minion02:
    10.0.1.161
[root@master files]#

把安装zabbi_agent的状态模块include系统初始化模块里

[root@master init]# pwd
/srv/salt/base/init
[root@master init]# ll
total 28
-rw-r--r-- 1 root root  173 Jan  1 21:39 audit.sls
-rw-r--r-- 1 root root  131 Jan  1 21:20 dns.sls
-rw-r--r-- 1 root root   92 Jan  2 16:18 env_init.sls
drwxr-xr-x 2 root root 4096 Jan  2 16:09 files
-rw-r--r-- 1 root root   88 Jan  1 21:25 history.sls
-rw-r--r-- 1 root root  174 Jan  1 21:55 sysctl.sls
-rw-r--r-- 1 root root  466 Jan  2 15:58 zabbix_agent.sls
[root@master init]# cat env_init.sls
include:
  - init.dns
  - init.history
  - init.audit
  - init.sysctl
  - init.zabbix_agent
[root@master init]#

　　至此zabbix-agent也安装完成
