打包/data/mysql-5721下的所有文件拷贝到节点2，然后启动mysql,并修改server_id
创建mysql复制特性：
创建复制用户：mysql中的slave若想获取二进制日志，它是得主动连接master节点去请求数据。因为slave节点将关于master的配置都保存在master.info文件中，该文件明文记录连接master节点的所有配置，包括连接的用户名、密码。所以最好在主库单独建个复制账户保证安全性。
MASTER：
grant replication slave on *.* to 'repl' @'20.58.8.%' identified by 'xxxxxx';
FLUSH PRIVILEGES;
删除slave端data下的auto.cnf
rm /mysql/data/auto.cnf
SLAVE：
启动slave服务并配置slave到master的连接：
change master to master_host='20.58.8.61',master_port=23306,master_user='repl',master_password='xxxxxx',master_auto_position=1;
start slave;
测试：在从库上执行
show global variables like "%server%";
show master status;
create database jason;
create table jason.jason_v2(id int);
