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

minion01:

[root@master files]# salt '*' pillar.items

把安装zabbi_agent的状态模块include系统初始化模块里
[root@master init]# pwd
