SaltStack安裝zabbix-agent-第九篇

環境

node1  192.168.56.11   角色 salt-master 

node2  192.168.56.12   角色  salt-minon

實現內容

使用salt遠程安裝zabbix-agent

步驟

環境是基於前幾篇博客基礎上Master和minion已經配置完成

一，創建zabbix項目文件夾，用於存放狀態文件

[root@linux-node1 base]# mkdir /srv/salt/base/zabbix -p
[root@linux-node1 base]# mkdir /srv/salt/base/init/files -p #用於存放系統相關初始化的信息

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，拷貝zabbix配置文件作為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模板變量到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狀態文件管理

[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，寫zabbix-agent的狀態文件

[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，測試

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

九，登陸到node2上面，zabbix 已正常啟動

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

總結

1.Jinja模板變量名不支持中橫線 -

2.狀態文件可以根據項目或服務進行分類管理

3.狀態文件支持include功能，支持正則匹配minion id

4.在編寫狀態文件之前需要先查清楚相關的軟件包名稱及配置文件名稱

5.要習慣先用test=True進行測試，避免不必要的故障

6.基礎的東西（jdk，web應用等） 通用的安裝全放在一個目錄,然后使用include功能

7.做好狀態模塊之間的依賴關系，避免不必要的狀態執行
