1.docker安装zabbix

mkdir -p /opt/zabbix/{conf,data,backups}
 
cat > docker-compose.yml <<-'EOF'
version: '3.3'
 
services:
  mysql-server:
    image: mysql:8.1
    container_name: mysql-server
    restart: unless-stopped
    environment:
      MYSQL_DATABASE: zabbix
      MYSQL_USER: zabbix
      MYSQL_PASSWORD: zabbix_pwd
      MYSQL_ROOT_PASSWORD: root_pwd
      TZ: Asia/Shanghai
    volumes:
      - /opt/zabbix/data:/var/lib/mysql
    networks:
      - zabbix-net
    command: --character-set-server=utf8 --collation-server=utf8_bin --default-authentication-plugin=mysql_native_password
 
  zabbix-java-gateway:
    image: zabbix/zabbix-java-gateway:latest
    container_name: zabbix-java-gateway
    restart: always
    ports:
      - "10052:10052"
    environment:
      TZ: Asia/Shanghai
    networks:
      - zabbix-net
 
  zabbix-server-mysql:
    image: zabbix/zabbix-server-mysql:latest
    container_name: zabbix-server-mysql
    restart: unless-stopped
    environment:
      DB_SERVER_HOST: mysql-server
      MYSQL_DATABASE: zabbix
      MYSQL_USER: zabbix
      MYSQL_PASSWORD: zabbix_pwd
      MYSQL_ROOT_PASSWORD: root_pwd
      ZBX_JAVAGATEWAY: zabbix-java-gateway
      TZ: Asia/Shanghai
    ports:
      - "10051:10051"
    networks:
      - zabbix-net
 
  zabbix-web-nginx-mysql:
    image: zabbix/zabbix-web-nginx-mysql:latest
    container_name: zabbix-web-nginx-mysql
    restart: unless-stopped
    environment:
      ZBX_SERVER_HOST: zabbix-server-mysql
      DB_SERVER_HOST: mysql-server
      MYSQL_DATABASE: zabbix
      MYSQL_USER: zabbix
      MYSQL_PASSWORD: zabbix_pwd
      MYSQL_ROOT_PASSWORD: root_pwd
      TZ: Asia/Shanghai
    ports:
      - "80:8080"
    networks:
      - zabbix-net
 
 
networks:
  zabbix-net:
EOF
 

#启动zabbix
docker-compose up -d
 

2.备份mysql

 
yum install -y mariadb mariadb-server && yum clean all
 
#备份mysql脚本
cat > /opt/zabbix/backups/backup_mysql.sh <<-'EOF'
#!/bin/bash
 
# 获取当前日期
current_date=$(date +%Y%m%d_%H%M%S)
 
# 获取容器的 IP 地址
ipname=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' mysql-server)
 
# 设置 MySQL 密码环境变量
export MYSQL_PWD=root_pwd
 
# 执行备份命令
mysqldump -h $ipname -u root zabbix > /opt/zabbix/backups/zabbix_$current_date.sql
 
# 检查备份是否成功
if [ $? -eq 0 ]; then
    echo "Backup successful!"
else
    echo "Backup failed!"
fi
 
# 清理超过15天的备份文件
find /opt/zabbix/backups/ -type f -name 'zabbix_*.sql' -mtime +15 -exec rm {} \;
 
EOF
 
chmod +x /opt/zabbix/backups/backup_mysql.sh
 
# 定义要添加的任务
TASK="0 0 * * * /opt/zabbix/backups/backup_mysql.sh"
 
# 添加新任务
(crontab -l; echo "$TASK") | crontab -
 
crontab -l
 
 

3.开放防火墙端口

 
firewall-cmd --zone=public --add-port=10052/tcp --permanent
firewall-cmd --zone=public --add-port=10051/tcp --permanent
firewall-cmd --zone=public --add-port=10050/tcp --permanent
firewall-cmd --zone=public --add-port=80/tcp --permanent
 
#--重载
firewall-cmd --reload
 
#--查询已经开放的端口
firewall-cmd --list-port
 
 

4.清理zabbix

#清除zabbix
docker stop mysql-server zabbix-server-mysql zabbix-web-nginx-mysql zabbix_agent zabbix-java-gateway
 
docker rm mysql-server zabbix-server-mysql zabbix-web-nginx-mysql zabbix_agent zabbix-java-gateway
