## 实验环境 ##

[root@zabbix_server ~]# cat /etc/redhat-release 
    CentOS Linux release 7.6.1810 (Core)

## 一、Docker ##

1、安装

[root@zabbix_server ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
    [root@zabbix_server ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
    [root@zabbix_server ~]# yum install -y docker-ce docker-ce-cli containerd.io

2、启动

[root@zabbix_server ~]# systemctl start docker
    [root@zabbix_server ~]# systemctl enable  docker

## 二、Docker安装zabbix的两种方式 ##

Zabbix官网手册：[https://www.zabbix.com/documentation/4.0/zh/manual/installation/containers][https_www.zabbix.com_documentation_4.0_zh_manual_installation_containers]

1、直接使用docker run示例，官网提供了三个不同示例

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70][]  
2、使用docker-compose命令运行yaml脚本，本文主要也是说明这个。这个命令将会为每个 Zabbix 组件下载最新的 Zabbix 4.0 镜像，并以 detach 模式运行

## 三、Docker Compose ##

GitHub官网：[https://github.com/docker/compose/releases][https_github.com_docker_compose_releases]

1、安装docker-compose

[root@zabbix_server ~]# curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose   
      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                     Dload  Upload   Total   Spent    Left  Speed
    100   617    0   617    0     0    495      0 --:--:--  0:00:01 --:--:--   496
    100 15.4M  100 15.4M    0     0   177k      0  0:01:28  0:01:28 --:--:--  115k
    
    #给二进制文件执行权限
    [root@zabbix_server ~]# chmod +x /usr/local/bin/docker-compose
    
    #查看版本
    [root@zabbix_server ~]# docker-compose --version
    docker-compose version 1.24.1, build 4667896b

2、GitHub下载脚本，这里选择了master节点下载

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 1][]

3、创建一个存放目录，把下载所有以点开头的环境变量文件和一个yaml文件上传到zabbix\_server服务器（因为实验系统是centos,所以选择了docker-compose\_v3\_centos\_mysql\_latest.yaml，根据需求参考）

[root@zabbix_server ~]# mkdir  zabbix
    [root@zabbix_server ~]# cd zabbix/

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 2][]

4、docker-compose\_v3\_centos\_mysql\_latest.yaml还可以根据需求进一步优化

本文选择安装：zabbix-server、zabbix-web-apache-mysql、zabbix-agent、zabbix-snmptraps、mysql-server

注意：在每个基础镜像下添加restart: always，要不容器退出之后无法自动启动

[root@zabbix_server zabbix]# vim docker-compose_v3_centos_mysql_latest.yaml

version: '3.5'
    services:
     zabbix-server:
      image: zabbix/zabbix-server-mysql:centos-latest	#基础镜像
      restart: always	#指定容器退出后的重启策略为始终重启。该命令对保持服务始终运行十分有效，在生产环境中推荐配置为always或者unless-stopped。

        file: ./.MYSQL_ROOT_PASSWORD

5、安装zabbix

因为是联网下载镜像所以会很慢。推荐搭建harbor镜像仓库，然后通过内网去下载

[root@zabbix_server zabbix]# docker-compose -f ./docker-compose_v3_centos_mysql_latest.yaml  up -d

6、查看容器

[root@zabbix_server zabbix]# docker ps -a
    CONTAINER ID        IMAGE                                          COMMAND                  CREATED             STATUS                    PORTS                                      NAMES
    6499dc6b25a7        zabbix/zabbix-web-apache-mysql:centos-latest   "docker-entrypoint.sh"   16 minutes ago      Up 16 minutes (healthy)   0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp   zabbix_zabbix-web-apache-mysql_1

    af9a34a8172b        mysql:5.7                                      "docker-entrypoint.s…"   16 minutes ago      Up 16 minutes                                                        zabbix_mysql-server_1

## 四、解决Zabbix agent is not available ##

1、浏览器登录http://192.168.14.216 如果无法登录，先关闭主机防火墙

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 3][]

2、接口IP不能是127.0.0.1，127.0.0.1是宿主机的。

3、查看zabbix\_zabbix-agent\_1容器的IP地址

![20191113154736695.png][]

4、点击进入Zabbix server修改IP地址，等会绿色就是正常
