ansible实现zabbix-server的搭建

node1：192.168.91.139：zabbix-server
node2：192.168.91.137：ansible

在node2:

实现各主机间ssh无密钥通信
[root@localhost ~]#ssh-key

[root@localhost ~]#ssh-copy-id [email protected]

[root@localhost ~]#ls .ssh/
authorized_keys  id_rsa  id_rsa.pub  known_hosts

[root@localhost ~]#scp -r .ssh/* 192.168.91.139:~/.ssh/

安装ansible
[root@localhost ~]#yum install -y ansible

创建主机清单
[root@localhost ~]#vim /etc/ansible/hosts 
	[zabbixsrv]
	192.168.91.139

测试
[root@localhost ~]#ansible zabbixsrv -m ping
192.168.91.139 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}

生成roles文件
[root@localhost ~]#mkdir /etc/ansible/roles/zabbixsrv/{files,templates,tasks,handlers,vars,defaults,meta} -pv

[root@localhost ~]#tree /etc/ansible/
/etc/ansible/

[root@localhost /etc/ansible]#vim ~/zabbixsrv.sh 
#!/bin/bash
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm		#安装官方仓库
yum clean all
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

提前准备zabbix_server.conf,修改配置并放到/etc/ansible/roles/zabbixsrv/files/下
DBHost=192.168.91.139
DBName=zabbix
DBUser=zabbix
DBPassword=122333

[root@localhost /etc/ansible]#vim roles/zabbixsrv/tasks/main.yml

[root@localhost /etc/ansible]#mkdir roles/mariadb/{files,tasks} -pv

提前准备my.cnf，放到/etc/ansible/roles/mariadb/files/

[root@localhost /etc/ansible]#vim ~/mariadb.sh

#倒数数据库
