> 部署mysql 5.7 叢集master & slave （僅測試用）
鏡像版本5.7
1、建立overlay 網路
docker network create --driver overlay common-network --attachable
2、編輯兩個設定檔master.cnf 與slave.cnf
!includedir /etc/mysql/conf.d/ !includedir /etc/mysql/mysql.conf.d/ [mysqld] log-bin=mysql-bin server-id=1 gtid-mode=on enforce-gtid-consistency=on
!includedir /etc/mysql/conf.d/ !includedir /etc/mysql/mysql.conf.d/ [mysqld] server-id=2 gtid-mode=on enforce-gtid-consistency=on
3、啟動2 個mysql：mysql-master 、mysql-slave
docker run -d \ --name mysql-master \ --network common-network \ -e mysql_root_password=passw0rd \ -v `pwd`/master.cnf:/etc/mysql/my.cnf \ -p 3306:3306 \ -d mysql:5.7
docker run -d \ --name mysql-slave \ --network common-network \ -e mysql_root_password=passw0rd \ -v `pwd`/slave.cnf:/etc/mysql/my.cnf \ -p 3307:3306 \ -d mysql:5.7
4、新增從庫用於複製的使用者
docker run -it --rm --network common-network mysql mysql -hmysql-master -uroot -ppassw0rd \ -e "create user 'repl'@'%' identified by 'password' require ssl; " \ -e "grant replication slave on *.* to 'repl'@'%';"
5、連接master & slave
docker run -it --rm --network common-network mysql mysql -hmysql-slave -uroot -ppassw0rd \ -e "change master to master_host='mysql-master', master_port=3306, master_user='repl', master_password='password', master_auto_position=1, master_ssl=1;" \ -e "start slave;"
6、驗證slave 狀態
docker run -it --rm --network common-network mysql mysql -hmysql-slave -uroot -ppassw0rd -e "show slave status\g"
如下狀態為正常：
slave_io_running: yes
slave_sql_running: yes
##> 部署mysql 8.0 叢集master & slave（僅測試用#> 部署mysql 8.0 叢集master & slave（僅測試用）
鏡像版本mysql:8.0
1、建立overlay 網路
docker network create --driver overlay common-network --attachable
2、啟動2 個mysql：mysql-master 、 mysql-slave
docker run -d \ --name mysql-master \ --network common-network \ -e mysql_root_password=passw0rd \ -p 3306:3306 \ -d mysql --default-authentication-plugin=mysql_native_password
docker run -d \ --name mysql-slave \ --network common-network \ -e mysql_root_password=passw0rd \ -p 3307:3306 \ -d mysql --default-authentication-plugin=mysql_native_password
3、設定master & slave
docker run -it --rm --network common-network mysql mysql -hmysql-master -uroot -ppassw0rd \ -e "set persist server_id=1;" \ -e "set persist_only gtid_mode=on;" \ -e "set persist_only enforce_gtid_consistency=true; " \ -e "create user 'repl'@'%' identified by 'password' require ssl; " \ -e "grant replication slave on *.* to 'repl'@'%';"
docker run -it --rm --network common-network mysql mysql -hmysql-slave -uroot -ppassw0rd \ -e "set persist server_id=2;" \ -e "set persist_only gtid_mode=on;" \ -e "set persist_only enforce_gtid_consistency=true; "
4、重啟master & slave
docker restart mysql-master mysql-slave
5、連線master & slave
docker run -it --rm --network common-network mysql mysql -hmysql-slave -uroot -ppassw0rd \ -e "change master to master_host='mysql-master', master_port=3306, master_user='repl', master_password='password', master_auto_position=1, master_ssl=1;" \ -e "start slave;"
6、驗證slave 狀態
docker run -it --rm --network common-network mysql mysql -hmysql-slave -uroot -ppassw0rd -e "show slave status\g"
如下狀態為正常：
slave_io_running: yes
slave_sql_running: yes
> 驗證資料同步
在master 建立資料庫anoyi
docker run -it --rm --network common-network mysql mysql -hmysql-master -uroot -ppassw0rd \ -e "create database anoyi default character set utf8mb4 collate utf8mb4_general_ci;"
在slave 檢視資料庫清單
docker run -it --rm --network common-network mysql mysql -hmysql-slave -uroot -ppassw0rd \ -e "show databases;" mysql: [warning] using a password on the command line interface can be insecure. +--------------------+ | database | +--------------------+ | anoyi | | information_schema | | mysql | | performance_schema | | sys | +--------------------+
