SaltStack安装zabbix-agent-第九篇

环境

node1  192.168.56.11   角色 salt-master 

node2  192.168.56.12   角色  salt-minon

实现内容

使用salt远程安装zabbix-agent

步骤

环境是基于前几篇博客基础上Master和minion已经配置完成

一，创建zabbix项目文件夹，用于存放状态文件

[root@linux-node1 base]# mkdir /srv/salt/base/zabbix -p
[root@linux-node1 base]# mkdir /srv/salt/base/init/files -p #用于存放系统相关初始化的信息

二，配置salt的epel源文件

[root@linux-node1 files]# pwd
/srv/salt/base/init/files
[root@linux-node1 files]# wget http://mirrors.aliyun.com/repo/epel-7.repo
--2017-10-22 19:50:35--  http://mirrors.aliyun.com/repo/epel-7.repo
......

三，拷贝zabbix配置文件作为salt的zabbix源文件

[root@linux-node1 zabbix]# yum list |grep zabbix22-agent
zabbix22-agent.x86_64                    2.2.20-1.el7                   epel   

[root@linux-node1 zabbix]# ll  /etc/zabbix/zabbix_agentd.conf 
lrwxrwxrwx 1 root root 22 Oct 22 20:03 /etc/zabbix/zabbix_agent.conf -> /etc/zabbix_agent.conf

[root@linux-node1 zabbix]# mkdir /srv/salt/base/zabbix/files
[root@linux-node1 zabbix]# cp /etc/zabbix_agentd.conf /srv/salt/base/zabbix/files

四，添加jiaja模板变量到salt的zabbix源文件

[root@linux-node1 files]# grep ^[a-Z] zabbix_agentd.conf
PidFile=/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server={{ ZABBIX_SERVER }} 
Hostname={{ AGENT_HOSTNAME }}
Include=/etc/zabbix_agentd.conf.d/

五，配置epel状态文件管理

[root@linux-node1 init]# pwd
/srv/salt/base/init
[root@linux-node1 init]# vim yum-repo.sls
[root@linux-node1 init]# cat yum-repo.sls 
/etc/yum.repos.d/epel-7.repo:
  file.managed:
    - source: salt://init/files/epel-7.repo
    - user: root
    - group: root
    - mode: 644

六，写zabbix-agent的状态文件

[root@linux-node1 zabbix]# pwd
/srv/salt/base/zabbix
[root@linux-node1 zabbix]# cat zabbix-agent.sls 
include:   #支持include功能
  - init.yum-repo

zabbix-agent:
  pkg.installed:
    - name: zabbix22-agent
    - require: 
      - file: /etc/yum.repos.d/epel-7.repo
  file.managed:
    - name: /etc/zabbix_agentd.conf
    - source: salt://zabbix/files/zabbix_agentd.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    - defaults:
      ZABBIX_SERVER: 192.168.56.12
      AGENT_HOSTNAME: {{ grains['fqdn'] }}
    - require:
      - pkg: zabbix-agent
  service.running:
    - name: zabbix-agent
    - enable: True
    - watch:
      - file: zabbix-agent
      - pkg: zabbix-agent

zabbix_agentd.conf.d:
  file.directory:
    - name: /etc/zabbix_agentd.conf.d
    - watch_in:
      - service: zabbix-agent
    - require:
      - pkg: zabbix-agent
      - file: zabbix-agent

七，测试

[root@linux-node1 files]# salt 'linux-node2*' state.sls zabbix.zabbix-agent test=True
linux-node2.example.com:

九，登陆到node2上面，zabbix 已正常启动

[root@linux-node2 ~]# ps aux |grep zabbix
zabbix     4595  0.0  0.0  77792  1364 ?        S    20:34   0:00 /usr/sbin/zabbix_agentd

总结

1.Jinja模板变量名不支持中横线 -

2.状态文件可以根据项目或服务进行分类管理

3.状态文件支持include功能，支持正则匹配minion id

4.在编写状态文件之前需要先查清楚相关的软件包名称及配置文件名称

5.要习惯先用test=True进行测试，避免不必要的故障

6.基础的东西（jdk，web应用等） 通用的安装全放在一个目录,然后使用include功能

7.做好状态模块之间的依赖关系，避免不必要的状态执行
