系统环境:
首先,修改mysql配置文件:/etc/mysql/my.cnf
[master]
#master 同步设置
server-id = 1
log_bin = /var/log/mysql/mysql-test-bin.log
expire_logs_days = 10
max_binlog_size = 100M
binlog_format =mixed
[slave]
server-id = 2
replicate-do-db=test
replicate-do-db=blog
log_bin = /var/log/mysql/mysql-bin.log
relay_log =/var/log/mysql/mysql-relay-bin.log
expire_logs_days = 10
max_binlog_size = 100M
#binlog_do_db = test
#binlog_ignore_db = include_database_name
binlog_format = mixed
slave-net-timeout=6012 master-connect-retry=10
第二步,在master上创建备份帐号
将master中的数据库 导入到slave中,先锁表,禁止写入操作。
先从master导出:
再导入到slave:
进入master上的mysql,查看master状态
进入slave上的Mysql
然后启动salve,并查看状态:
start slave;
mysql> show slave statusG;

最后,解锁master上的表:
