ZabbixAgent2进行容器和主机监控(Docker部署)

一、Zabbix部署

Zabbix是一个常用的基于WEB界面的监控解决方案，可以对主机等设备进行较为详尽的参数和状态监控。zabbix由两部分组成，zabbix server作为监控服务器，可进行主动监控、数据收集、数据可视化等；被监控设备需要安装zabbix agent，可设置为主动发送模式来减轻zabbix server的工作压力。

但Zabbix不能直接对容器container进行监控，必须使用ZabbixAgent2安装在被监控主机上，此时可监控到被监控的主机及被监控主机的容器信息。

环境：

• CentOS 8
• Mysql
• nginx

1.安装zabbix

# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/8/x86_64/zabbix-release-5.0-1.el8.noarch.rpm
# dnf clean all

2.安装Zabbix server,Web前端,zabbix agent

# dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-agent

3.安装Mysql

# dnf install -y mysql-server mysql-devel mysql-libs
# systemctl start mysqld
# mysql_secure_installation
# mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> quit;

二、Docker部署Zabbix Server

两种方式进行部署皆可

1.docker run(没写挂载，未持久化)

启动server端和mysql

# 启动mysql
docker run --name zabbix-mysql --hostname zabbix-mysql -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix" -e MYSQL_ROOT_PASSWORD="rootpwd" --character-set-server=utf8 --collation-server=utf8_bin -d mysql:5.7

#启动zabbix-server
docker run --name zabbix-server -p 10051:10051 -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix" -e MYSQL_ROOT_PASSWORD="rootpwd" -links zabbix-mysql:mysql -d zabbix/zabbix-server-mysql

# 启动zabbix-web-nginx-mysql
# 注意，在docker中，端口是8080而不是80，这里把8080暴露至宿主机8081
docker run --name zabbix-web-nginx-mysql -p 8081:8080 -p 8443:443 -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix" -links mysql-server:mysql -links zabbix-server:zabbix-server -d zabbix/zabbix-web-nginx-mysql

2.docker-compose

mysql和server端docker-compose.yml

version: '3.8'
services:
 mysql-server:
  image: mysql:5.7
  container_name: mysql-server
  environment:
   - MYSQL_DATABASE=zabbix
   - MYSQL_USER=zabbix
   - MYSQL_PASSWORD=zabbix
   - MYSQL_ROOT_PASSWORD=rootpwd
  volumes:
   - /srv/zbx_env/var/lib/mysql:/var/lib/mysql:rw
  command:
   - mysqld
   - --character-set-server=utf8
   - --collation-server=utf8_bin
   - --default-authentication-plugin=mysql_native_password

 zabbix-server:
  image: zabbix/zabbix-server-mysql:latest
  container_name: zabbix-server
  ports:
   - 10051:10051
  environment:
   - MYSQL_DATABASE=zabbix
   - MYSQL_USER=zabbix
   - MYSQL_PASSWORD=zabbix
   - MYSQL_ROOT_PASSWORD=rootpwd
  volumes:
   - /etc/localtime:/etc/localtime:ro
   - /etc/timezone:/etc/timezone:ro
   - /srv/zbx_env/usr/lib/zabbix/alertscripts:/usr/lib/zabbix/alertscripts:ro
   - /srv/zbx_env/usr/lib/zabbix/externalscripts:/usr/lib/zabbix/externalscripts:ro
   - /srv/zbx_env/var/lib/zabbix/export:/var/lib/zabbix/export:rw
   - /srv/zbx_env/var/lib/zabbix/modules:/var/lib/zabbix/modules:ro
   - /srv/zbx_env/var/lib/zabbix/enc:/var/lib/zabbix/enc:ro
   - /srv/zbx_env/var/lib/zabbix/ssh_keys:/var/lib/zabbix/ssh_keys:ro
   - /srv/zbx_env/var/lib/zabbix/mibs:/var/lib/zabbix/mibs:ro
  links:
   - mysql-server:mysql
  depends_on:
   - mysql-server

 zabbix-web-nginx-mysql:
  image: zabbix/zabbix-web-nginx-mysql:latest
  ports:
   - 8080:8080
   - 8443:443
  environment:
   - MYSQL_USER=zabbix
   - MYSQL_PASSWORD=zabbix
  links:
   - mysql-server:mysql
   - zabbix-server:zabbix-server
  volumes:
   - /etc/localtime:/etc/localtime:ro
   - /etc/timezone:/etc/timezone:ro
   - /srv/zbx_env/etc/ssl/nginx:/etc/ssl/nginx:ro
   - /srv/zbx_env/usr/share/zabbix/modules/:/usr/share/zabbix/modules/:ro
  depends_on:
   - mysql-server
   - zabbix-server

三、Docker部署zabbix agent2

同样是两种方式

1.启动zabbix agent2

# 注意！一定要挂载docker.sock，不然无法和docker进行通信
docker run --name zabbix-agent2 -v /var/run/docker.sock:/var/run/docker.sock -u 0:0 -e ZBX_HOSTNAME="zabbix-agent2" -e ZBX_SERVER_HOST="xxx.xxx.xxx.xxx" -e ZBX_SERVER_PORT=10051 -d zabbix/zabbix-agent2

2.zabbix-agent2的docker-compose.yml

version: '3.8'
services:
 zabbix-agent2:
  image: zabbix/zabbix-agent2:latest
  container_name: zabbix-agent2
  ports:
   - 10050:10050
  environment:
   - ZBX_HOSTNAME=zabbix-agent2
   - ZBX_SERVER_HOST=xxx.xxx.xxx.xxx
  volumes:
   - /etc/localtime:/etc/localtime:ro
   - /etc/timezone:/etc/timezone:ro
   - /srv/zbx_env/etc/zabbix/zabbix_agentd.d:/etc/zabbix/zabbix_agentd.d:ro
   - /srv/zbx_env/var/lib/zabbix/modules:/var/lib/zabbix/modules:ro
   - /srv/zbx_env/var/lib/zabbix/enc:/var/lib/zabbix/enc:ro
   - /srv/zbx_env/var/lib/zabbix/ssh_keys:/var/lib/zabbix/ssh_keys:ro
   - /var/run/docker.sock:/var/run/docker.sock:ro
  user: 0:0
  privileged: true
  restart: always
  networks:
   - zabbix_default

networks:
 zabbix_default:
  external: true
