Description

Version: ' 2 ' Services:    Web:    //Service name      image:wordpress:latest  //Mirror name      depends_on:   //Dependent service name, That is, it must be started after this service is started        -db      Links:   //link to the service, that is, for this service flood container, the network is transparent, can directly use its internal port access        -DB      ports:  // Port host mapping, on the outside can use 8002 access to the website        -"8002:80"      Environment://environment variable        wordpress_db_host:db:3306  //Database address, The service name and port, as it already links, will automatically address        wordpress_db_password:123456//Database Password      volumes:        -/home/jinhan/wordpress :/var/www/html  //Mount volume, pull image will download WordPress here, we mount it locally, so we can modify the local file    db:       image:mysql      ports:         -"8003:3306"      Environment:         -mysql_root_password=123456      volumes:        -/home/jinhan/mysql/ Data:/var/lib/mysql  //database data, hanging locally        -/home/jinhan/mysql/conf:/etc/mysql/conf.d//Database configuration, we're going to put it ourselves.

Four. Mounting volumes

We're experimenting with MySQL and WordPress.

Configure MySQL config to increase the number of connections because the number of connections can explode:

Mkdir-p/home/jinhan/mysql/confvim/home/jinhan/mysql/conf/my.cnf[mysqld]max_connections = 15000max_connect_errors = 6000open_files_limit = 65535table_open_cache = 1000skip-name-resolve

We've hung all the volumes locally so that your data will not go away every time you start!

Five. Start

Docker-compose up

Browser access: http://127.0.0.1:8002/database access: root:123456 Port 8003

If

Show variables like '%max_connect% ';

Display 15000, configuration successful!

Six. View

Docker-compose PS

Seven. Background boot

Docker-compose up-d

Eight. View logs

Docker-compose logs-f

Nine. Delete a container

Docker-compose RM

10. Ask for help
