用saltstack批量安装zabbix_agent

前提：此文档仅支持在CentOS上安装zabbix_agent。
环境：
salt-master: 172.16.0.197
salt-minions: 172.16.0.225, 172.16.0.233, 172.16.0.234, 172.16.0.226, 172.16.0.236

一、准备工作

salt-master

1. 安装salt-master

curl -L https://bootstrap.saltstack.com -o install_salt.sh
sudo sh install_salt.sh -P -M

2. 编辑/etc/salt/master

file_roots:
  base:
    - /srv/salt/base/

pillar_roots:
  base:
    - /srv/pillar/base/

3. 启动salt-master
   centos6
   service salt-master start
   centos7
   systemctl start salt-master
4. 首先在每台需要安装zabbix_agent的机器上部署salt-minion

curl -L https://bootstrap.saltstack.com -o install_salt.sh
sudo sh install_salt.sh -P

5. 修改/etc/salt/minion文件

#master: salt
master: 172.16.0.197

6. 启动salt-minion
   centos6
   service salt-minion start
   centos7
   systemctl start salt-minion

7. 在salt-master上用salt-key -A将各minion添加认证
   然后用salt '*' test.ping测试，都显示为True

[root@localhost ~]# salt '*' test.ping
172.16.0.225:
    True
172.16.0.233:
    True
172.16.0.234:
    True
172.16.0.236:
    True
172.16.0.226:
    True

二、部署

1. 准备目录
   mkdir -p /srv/salt/base/init/files
   init目录用来表示这个目录下的文件是用来系统初始化的，也就是没个系统必须具备的
   files目录用来存放一些安装包和配置文件
   将zabbix-3.4.8.tar.gz和zabbix_agentd.conf保存到files目录下，tar包可以官网下载，zabbix_agentd.conf可以从已经安装过的机器中拷贝过来
2. 通过Pillar来设置Zabbix Server值

[root@localhost ~]# vim /srv/pillar/base/top.sls 
base:
  '*':
    - zabbix

[root@localhost ~]# vim /srv/pillar/base/zabbix.sls 
zabbix-agent:
  Zabbix_Server: 172.16.0.174

3. 创建启动zabbix_agentd的用户

[root@localhost ~]# mkdir /srv/salt/base/user
[root@localhost ~]# vim /usr/salt/base/user/zabbix.sls
zabbix-user-group:
  group.present:
    - name: zabbix
    - gid: 1000

  user.present:
    - name: zabbix
    - fullname: zabbix
    - shell: /sbin/nologin
    - uid: 1000
    - gid: 1000

4. 安装依赖包

[root@localhost ~]# vim /srv/salt/base/init/pkg-init.sls
pkg-init:
  pkg.installed:
    - names: 
      - gcc
      - gcc-c++
      - glibc
      - openssl
      - openssl-devel
      - pcre-devel

这里还可以添加你需要安装的一些基础包

4. 编写安装文件

[root@mycat ~]# cat /srv/salt/base/init/zabbix_agent.sls 
include:
  - user.zabbix

zabbix-install:
  file.managed:
    - name: /usr/local/src/zabbix-3.4.8.tar.gz
    - source: salt://init/files/zabbix-3.4.8.tar.gz
    - mode: 755
    - user: zabbix
    - group: zabbix
  cmd.run:
    - name: cd /usr/local/src && tar zxf zabbix-3.4.8.tar.gz && cd zabbix-3.4.8 && ./configure --prefix=/usr/local/zabbix --enable-agent && make install
    - unless: test -d /usr/local/zabbix
    - require:
      - user: zabbix-user-group
      - file: zabbix-install

zabbix-agent:
  file.managed:
    - name: /usr/local/zabbix/etc/zabbix_agentd.conf
    - source: salt://init/files/zabbix_agentd.conf
    - template: jinja
    - defaults:
      Server: {{ pillar['zabbix-agent']['Zabbix_Server'] }}
      Hostname: {{ grains['fqdn'] }}
    - require:
      - file: zabbix-install

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

zabbix_agentd-start:
  cmd.run:
    - name: echo "/usr/local/zabbix/sbin/zabbix_agentd -c /usr/local/zabbix/etc/zabbix_agentd.conf" >> /etc/rc.d/rc.local && /usr/local/zabbix/sbin/zabbix_agentd -c /usr/local/zabbix/etc/zabbix_agentd.conf
    - require:
      - file: zabbix-install
    - watch:
      - file: zabbix-agent

5. 修改zabbix_agentd.conf文件

[root@mycat ~]# vim /srv/salt/base/init/files/zabbix_agentd.conf
Server={{ Server }}    #修改此行
Hostname= {{ Hostname }}    #修改此行
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d    #添加或者修改此行

6. 创建env_init.sls把初始环境的.sls文件都包含进来，这边我们只有一个zabbix和一组依赖包

[root@localhost ~]# vim /srv/salt/base/init/env_init.sls
include:
  - init.pkg-init
  - init.zabbix_agent

7. 在top.sls里面给Minion指定状态

[root@localhost ~]# vim /srv/salt/base/top.sls
base:
  '*':
    - init.env_init

8. 执行命令
   在执行前，先进行测试
   [root@localhost ~]# salt '*' state.highstate test=True
   在所有Minion上执行状态
   [root@localhost ~]# salt '*' state.highstate
