Ansible 部署 Zabbix 4

阅读本文章需要具有Ansible、Zabbix基础。本次教程基于如下环境：

CentOS 7.x
Zabbix 4.0
Ansible 2.5

服务器初始化

关闭防火墙、selinux，添加epel常用源，安装常用工具、添加普通用户并禁止root远程登录、重启服务器

cat init.yaml

---
- hosts: all

  tasks: 
    - name: disable selinux、firewalls,replace ali sources
      shell: |
        sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
        systemctl disable firewalld
        mkdir -p /etc/yum.repos.d/backup
        mv /etc/yum.repos.d/* /etc/yum.repos.d/backup/
        curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

    - name: ensure a list of packages installed
      yum:
        name: "{{ packages }}"
      vars:
        packages:
        - wget
        - vim
        - sysstat
        - lrzsz
        - lsof

    - name: Add the user centos 
      user:
        name: centos 
        group: wheel

    - name:  disabled root remote login
      replace:
        path: /etc/ssh/sshd_config
        regexp: '\#PermitRootLogin yes'
        replace: 'PermitRootLogin no'
        backup: yes

    - name: modify ssh port
      shell: sed -i '/^\#Port/a\Port 22201' /etc/ssh/sshd_config

    - name: restart ssh
      service:
        name: sshd
        state: restarted

    - name: Add epel and reboot server
      shell: |
        reboot

执行初始化

# ansible-playbooks init.yaml

Zabbix-Server部署

这个很惭愧，没做成playbooks。主要用shell

安装MySQL

安装MySQL5.6，并创建zabbix需要的数据库

# yum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm
# yum install Percona-Server-server-56 -y
# systemctl start mysqld

# mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'password';
mysql> quit;

安装zabbix-server

# yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent -y

导入表结构及数据

# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

修改配置文件

编辑 /etc/httpd/conf.d/zabbix.conf

# php_value date.timezone Europe/Riga

修改为

# php_value date.timezone Asia/Shanghai

编辑 /etc/zabbix/zabbix_server.conf

DBPassword=password

开启服务，并设置开机启动

# systemctl restart zabbix-server zabbix-agent httpd
# systemctl enable zabbix-server zabbix-agent httpd

Zabbix-Agent 部署

准备agent安装包、修改zabbix-agent.conf的shell脚本

# cd /root
# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-agent-4.0.2-1.el7.x86_64.rpm

cat zabbix_agent.sh

#!/bin/bash
# 将zabbix服务端从127.0.0.1换成server ip
# 将主机名设置为本机ip
# 开启服务
sed -i 's/127.0.0.1/172.16.103.57/g' /etc/zabbix/zabbix_agentd.conf

j=`/usr/sbin/ip a|grep enp2s1|grep inet|awk '{print $2}'|awk -F '/' '{print $1}'`
sed -i "s/Hostname=Zabbix server/Hostname=${j}/"  /etc/zabbix/zabbix_agentd.conf
systemctl start zabbix-agent

cat zabbix-agent.yaml

---
- hosts: all
  gather_facts:  false

  tasks: 
    - name: copy file
      copy: 
        src: /root/zabbix-agent-4.0.0-2.el7.x86_64.rpm
        dest: /tmp/zabbix-agent-4.0.0-2.el7.x86_64.rpm


    - name: install zabbix
      yum: 
        name: /tmp/zabbix-agent-4.0.0-2.el7.x86_64.rpm
        state: present

    - name: copy bash
      copy:
        src: /root/zabbix_agent.sh
        dest: /tmp/zabbix_agent.sh

    - name: exclude bash
      become: yes
      become_method: su
      shell: /bin/bash /tmp/zabbix_agent.sh
