MySQL Swarm是一種基于Docker的MySQL部署解決方案。它可以自動化地部署和管理MySQL集群。通過MySQL Swarm,開發(fā)人員可以輕松地創(chuàng)建一個始終可用的MySQL集群。
version: '3' services: mysql-master: image: mysql:5.7 volumes: - ./data/mysql-master:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD=root - MYSQL_DATABASE=wordpress - MYSQL_USER=wordpress - MYSQL_PASSWORD=wordpress deploy: replicas: 1 placement: constraints: - node.role == manager mysql-slave: image: mysql:5.7 volumes: - ./data/mysql-slave:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD=root - MYSQL_DATABASE=wordpress - MYSQL_USER=wordpress - MYSQL_PASSWORD=wordpress - MYSQL_MASTER_HOST=mysql-master deploy: replicas: 2 wordpress: image: wordpress:latest ports: - 8080:80 environment: - WORDPRESS_DB_HOST=mysql-master - WORDPRESS_DB_USER=wordpress - WORDPRESS_DB_PASSWORD=wordpress - WORDPRESS_DB_NAME=wordpress deploy: replicas: 2 phpmyadmin: image: phpmyadmin/phpmyadmin:latest ports: - 8888:80 environment: - PMA_HOST=mysql-master
上面的代碼是一個MySQL Swarm部署示例。該示例包含一個MySQL主節(jié)點、兩個MySQL從節(jié)點、兩個WordPress節(jié)點和一個phpMyAdmin節(jié)點。在這個示例中,MySQL主節(jié)點管理MySQL集群,并將其數(shù)據(jù)同步到從節(jié)點。WordPress節(jié)點提供WordPress服務(wù),而phpMyAdmin節(jié)點提供數(shù)據(jù)庫管理工具。通過使用Docker Swarm,可以輕松實現(xiàn)MySQL集群的自動化部署和管理。
