Replication安装配置

1.确保master和slave安装了相同的mysql版本

　　2.在master上创建复制使用的用户,并授予 replication slave权限

　　mysql> grant replication slave on *.* to 'repl'@'192.168.60.4' identified by 'hunter0';

　　Query OK, 0 rows affected (0.01 sec)

　　mysql> flush privileges;

　　Query OK, 0 rows affected (0.00 sec)

　　3.修改master上的my.cnf,开启binlog,并设置server-id

　　# The MySQL server

　　[mysqld]

　　server-id=1

　　port = 3306

　　socket = /var/lib/mysql/mysql.sock

　　datadir = /usr/local/mysql/data

　　log-error = /var/lib/mysql/test2_mysqld.err

　　#log-bin

　　log-bin = /var/lib/mysql/test2_log-bin

　　#query-log

　　#log = /var/lib/mysql/query_log.log

　　#slow-query-log

　　log-slow-queries = /var/lib/mysql/slow_query_log.log

　　skip-innodb

　　...................

　　4.在master上设置读锁定有效

　　mysql> flush tables with read lock;

　　Query OK, 0 rows affected (0.00 sec)

　　5.查看binlog和偏移量值,目的是为了使slave启动后,从这点开始数据恢复操作

　　mysql> show master status;

　　+----------------------+----------+--------------+------------------+

　　| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

　　+----------------------+----------+--------------+------------------+

　　| test2_log-bin.000002 | 311 | | |

　　+----------------------+----------+--------------+------------------+

　　1 row in set (0.00 sec)
