docker安装mysql_exporter

• 下载mysql_exporter镜像

docker pull prom/mysqld-exporter

• mysql_exporter需要链接数据库，mysql创建mysql_monitor用户，添加PROCESS, REPLICATION CLIENT权限

mysql> INSERT INTO mysql.user(Host,User,Password) VALUES("localhost", "mysql_monitor", password("mysql_monitor")); 
mysql> GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'mysql_monitor'@'localhost' IDENTIFIED BY 'mysql_monitor';
mysql> GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'mysql_monitor'@'%' IDENTIFIED BY 'mysql_monitor';
mysql> FLUSH PRIVILEGES;

• docker启动mysql_exporter镜像

docker run -d -p 9104:9104 \
  --name=mysqld-exporter \
  --restart=always \
  -e DATA_SOURCE_NAME="mysql_monitor:mysql_monitor@(172.17.0.1:3306)/" \
  prom/mysqld-exporter
