docker-compose安装zabbix5.0高可用
本次实验一共准备了，三台机器
| 主机名 | ip | 软件环境 |
|---|---|---|
| zabbix-server01 | 192.168.78.160 | nginx+keepalived+sshpass zabbix server+agent |
| zabbix-server02 | 192.168.78.164 | nginx+keepalived+sshpass zabbix server+agent |
| zabbix-mysql | 192.168.78.158 | zabbix agent+mysql |
我的做法agent中的配置文件，Server和ServerActive中分别都配置了两个ip，就是为了保证，zabbix-server01宕机了，还可以把监控数据发往zabbix-server02，由于两个zabbix-server共用一个数据库，肯定不能同时往数据库写数据，于是我想到了使用keepalived来控制zabbix server的开关，做到VIP在哪，那台机器的zabbix server就启动，另外一台关闭，而zabbix的web页面使用VIP去访问
准备工作
安装好docker软件
设置主机名
zabbix-mysql
[root@zabbix-mysql ~]# hostnamectl set-hostname zabbix-mysql
zabbix-server01
[root@zabbix-server01 ~]# hostnamectl set-hostname zabbix-server01
zabbix-server01
[root@zabbix-server02 ~]# hostnamectl set-hostname zabbix-server02
禁用防火墙和selinux
zabbix-mysql
[root@zabbix-mysql ~]# systemctl stop firewalld
[root@zabbix-mysql ~]# systemctl disable firewalld
[root@zabbix-mysql ~]# setenforce 0
[root@zabbix-mysql ~]# vim /etc/selinux/config
SELINUX=disabled
[root@zabbix-mysql ~]# getenforce
Permissive
zabbix-server01
[root@zabbix-server01 ~]# systemctl stop firewalld
[root@zabbix-server01 ~]# systemctl disable firewalld
[root@zabbix-server01 ~]# setenforce 0
[root@zabbix-server01 ~]# vim /etc/selinux/config
SELINUX=disabled
[root@zabbix-server01 ~]# getenforce
Permissive
zabbix-server02
[root@zabbix-server02 ~]# systemctl stop firewalld
[root@zabbix-server02 ~]# systemctl disable firewalld
[root@zabbix-server02 ~]# setenforce 0
[root@zabbix-server02 ~]# vim /etc/selinux/config
SELINUX=disabled
[root@zabbix-server02 ~]# getenforce
Permissive
优化ssh
zabbix-server01
[root@zabbix-server01 ~]# vim /etc/ssh/ssh_config
GSSAPIAuthentication no
[root@zabbix-server01 ~]# systemctl restart sshd
zabbix-server02
[root@zabbix-server02 ~]# vim /etc/ssh/ssh_config
GSSAPIAuthentication no
[root@zabbix-server02 ~]# systemctl restart sshd
安装sshpass
zabbix-server01
[root@zabbix-server01 ~]# yum -y install sshpass
zabbix-server012
[root@zabbix-server02 ~]# yum -y install sshpass
安装mysql和zabbix-agent
zabbix-mysql
