docker之单机构建mysql5.7主从服务

单独MySQL模式

参考我的上一文章：

http://blog.chinaunix.net/uid-30234663-id-5767316.html

这里部署的mysql5.7

  只需要把docker pull mariadb改成docker pull mysql:5.7即可

开始部署mysql主服务器

docker run -d -e TIMEZONE=Asia/Shanghai -v $PWD/mysql_master:/var/lib/mysql -v $PWD/my.cnf:/etc/mysql/my.cnf -p 3307:3306 -e MYSQL_ROOT_PASSWORD=hanye1311 -e MASTER=1 -e SERVER_ID=1 -e REPLICATION_PASSWORD=hanye131 --name mysql5.7_master mysql:5.7

从服务器

doc run -d --name mysql5.7_slave -e TIMEZONE=Asia/Shanghai -v $PWD/mysql_slave:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=hanye1312 -e SLAVE=1 -e SERVER_ID=3  -e REPLICATION_PASSWORD=hanye131 -e MASTER_LOG_FILE=mysql-bin.000003 -e MASTER_LOG_POS=154 -e MASTER_PORT=3306  -e MASTER_HOST=172.17.0.4 -p 4407:3306  mysql:5.7

然后和配置mysql主从配置一样即可

my.cnf

root@debian:~/mysql# cat my.cnf
