Docker 官方镜像构建你的zabbix 5.x

 

环境准备

先启动一个单独的数据库mysql用于保存zabbix数据

#注： 启动命令中不要添加 MYSQL_DATABASE="zabbix" 参数，不然后期同样在server上注册不上，会报user表为空的错误。同时--restart=always写在-d mysql:5.7的前面，要不然容器启动失败

定义了数据库名zabbix，数据库用户zabbix，密码zabbix，在本地目录/home/zabbix/data中持久化保存mysql容器运行中的数据，确保容器退出运行后，数据不会丢失，最后两条是定义了数据库的字符集为utf8，解决了mysql数据库保存中文的问题

 

然后启动Zabbix Server实例，并关联这个实例到已创建的MySQL实例

#zabbix server数据库配置信息如下：

bash-5.0$ cd /etc/zabbix/
bash-5.0$ grep DBHost zabbix_server.conf 
DBHost=mysql-server

#指定密码
bash-5.0$ grep DBPassword  zabbix_server.conf 
DBPassword=zabbix

启动zabbix server服务，并关联这个服务到上面已经启动的mysql数据库实例上，确保zabbix的数据可以保存到mysql数据库，如果想要数据持久化根据生产环境实际情况灵活决定是否挂载，上面我没有挂载，即没有使用卷持久化。

 

最后启动Zabbix web 接口，并将它与MySQL服务器实例和Zabbix Server实例关联

 link mysql-server:mysql 连接数据库实例，mysql-server必须要与第一步的--name mysql-server完全一致

--link zabbix-server-mysql:zabbix-server 连接zabbix服务器实例，zabbix-server-mysql必须要与第二步的--name zabbix-server-mysql完全一致

打开zabbix web界面

可以看到大功告成！ 

最后将这三个容器的启动命令记录一下：

docker run  --name mysql-server -t \

-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix" \
-e MYSQL_ROOT_PASSWORD="zabbix" \

--restart=always \
-d mysql:5.7  \
--character-set-server=utf8 \
--collation-server=utf8_bin


docker run  --name zabbix-server-mysql -itd \
-e DB_SERVER_HOST="mysql-server" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix" \
-e MYSQL_ROOT_PASSWORD="zabbix" \
--restart=always \
--link mysql-server:mysql \
-p 10051:10051 \
zabbix/zabbix-server-mysql:latest 


docker run --name zabbix-web-nginx-mysql -t \

      -e MYSQL_USER="zabbix" \
