MySQL Master Slave同步配置
环境：
PC：ubuntu 10.10 192.168.1.112（master） 192.168.10.245（slave）
MySQL : 5.1.49-1ubuntu8.1-log
在master中已经存在数据库test
首先修改mysql配置文件：/etc/mysql/my.cnf
[master]

1 #master 同步设置
2 server-id = 1
3 log_bin = /var/log/mysql/mysql-test-bin.log
4 expire_logs_days = 10
5 max_binlog_size = 100M
6 binlog_format =mixed
2 server-id = 1
3 log_bin = /var/log/mysql/mysql-test-bin.log
4 expire_logs_days = 10
5 max_binlog_size = 100M
6 binlog_format =mixed
[slave]

1 server-id = 2
2 replicate-do-db=test
3 replicate-do-db=blog
4 log_bin = /var/log/mysql/mysql-bin.log
5 relay_log =/var/log/mysql/mysql-relay-bin.log
6 expire_logs_days = 10
7 max_binlog_size = 100M
8 #binlog_do_db = test
9 #binlog_ignore_db = include_database_name
10 binlog_format = mixed
2 replicate-do-db=test
3 replicate-do-db=blog
4 log_bin = /var/log/mysql/mysql-bin.log
5 relay_log =/var/log/mysql/mysql-relay-bin.log
6 expire_logs_days = 10
7 max_binlog_size = 100M
8 #binlog_do_db = test
9 #binlog_ignore_db = include_database_name
10 binlog_format = mixed
11 slave-net-timeout=60
12 master-connect-retry=10
接着在master上创建备份帐号
1 grant replication slave,replication client on *.* to 'slave'@'192.168.10.245' identified by '123456';
将master中的数据库 导入到slave中，
先锁表，禁止写入操作
flush tables with read lock;
先从master导出：mysqldump -uroot -p test > /tmp/test.sql
再导入到slave： mysql -uroot -p test < /tmp/test.sql ,记得需要先建库test
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：

最后将master上的表解锁
unlock tables;
