Linux企业级——使用Playbook自动安装部署Zabbix
Linux企业级——使用Playbook自动安装部署Zabbix
实验环境：
| 虚拟机名称 | ip | 版本 | 角色 |
|---|---|---|---|
| server1 | 172.25.66.1 | 7.5 | ansible、zabbix-server、zabbix-agent |
| server2 | 172.25.66.2 | 7.5 | 远程主机hosts、db数据库 |
| server3 | 172.25.66.3 | 7.5 | 远程主机hosts、web前端 |
1.进行部署
1.1 编辑hosts文件：
[server]
172.25.66.2
[db]
172.25.66.1
[web]
172.25.66.3
[agent]
172.25.66.2
172.25.66.3
[zabbix:children]
server
web
db
1.2 创建zabbix目录
mkdir zabbix
1.3 添加playbook
vim deploy.yml

在playbook中的相关文件：
【1】数据库安全初始化文件 my.cnf
在server1：
安装数据库mariadb-server，并进行安全初始化。再将my.cnf拷贝到/home/devops/ansible/zabbix/目录下。
sudo cp /eth/my.cnf .
【3】数据库初始化包
在server1：
提前在安装zabbix-server-mysql，生成配置文件 /usr/share/doc/zabbix-server-mysql-4.0.14/create.sql.gz，将其拷贝到zabbix目录下。
cp /usr/share/doc/zabbix-server-mysql-4.0.14/create.sql.gz zabbix/
【4】zabbix_server.conf
在server1：
提前在server1上安装zabbix-server，生成配置文件/etc/zabbix/zabbix_server.conf，复制到zabbix目录下。编辑zabbix_server.conf。
sudo chown devops.devops zabbix_server.conf #修改所有人和所有组，直接复制过了所有人和所有组是root
vim zabbix_server.conf
91 BHost=172.25.66.1
116 DBUser=zabbix
124 DBPassword=zabbix
139 DBPort=3306
【5】zabbix.conf
在server3：
提前安装zabbix-web和httpd后生成zabbix.conf文件，将其复制到zabbix目录下，并修改时区
sudo scp 172.25.1.3:/etc/httpd/conf.d/zabbix.conf zabbix/
vim zabbix.conf
php_value date.timezone Asia/Shanghai
【6】zabbix_agentd.conf.j2
在server1：
提前安装zabbix-agent
cp /etc/zabbix/zabbix_agentd.conf zabbix/ .
mv zabbix/zabbix_agentd.conf zabbix/zabbix_agentd.conf.j2
