cd mysql-repl
chmod a+x install.sh
./install.sh

查看数据库是否启动程序

docker ps

查看数据库日志信息

docker logs -f repl    #查看实例repl1
docker logs -f rep2    #查看实例repl2

说明

主服务器实例名为 查看实例repl1,端口为3316
主服务器实例名为 查看实例repl2,端口为3317
mysql 的root 密码在docker-compose.yml文件中MYSQL_ROOT_PASSWORD 定义
mysql的my.cnf 文件在 repl1或者repl2目录下面

连接到数据库命令

• 连接到主库上

mysql -h 127.0.0.1 -P 3316 -p

• 连接到备库上

mysql -h 127.0.0.1 -P 3317 -p

• 连接到备库查看同步状态
