    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

    安装docker-compose

    [root@zabbix-mysql ~]# sudo curl -L "https://github.com/docker/compose/releases/download/1.27.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    [root@zabbix-mysql ~]# sudo chmod +x /usr/local/bin/docker-compose
    [root@zabbix-mysql ~]# docker-compose version
    docker-compose version 1.27.1, build 509cfb99
    docker-py version: 4.3.1
    CPython version: 3.7.7
    OpenSSL version: OpenSSL 1.1.0l  10 Sep 2019
    

    创建挂载目录

    [root@zabbix-mysql ~]# mkdir -p zabbix-HA-mysql/mysqldata
    [root@zabbix-mysql ~]# cd zabbix-HA-mysql
    

    编写docker-compose.yml
