master 192.168.0.9

slave 192.168.0.10

1主备都安装mysql软件

2编辑master /etc/my.conf

[mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysqllog-bin=mysql-binserver-id=1innodb_flush_log_at_trx_commit=1sync_binlog=1# Default to using old password format for compatibility with mysql 3.x# clients (those using the mysqlclient10 compatibility package).old_passwords=1[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.pid

3授权slave

[root@localhost mysql]# mysqlWelcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 6Server version: 5.0.45-log Source distributionType 'help;' or '\h' for help. Type '\c' to clear the buffer.mysql> grant replication slave,reload,super on *.* to 'slave'@'192.168.0.10' identified by '10086';mysql> flush privilegges;

从库登陆测试

mysql -uslave -p10086 -h 192.168.0.9

出现OK成功

4编辑slave /etc/my.cnf文件

[mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysqlserver-id=2master-host=192.168.0.9master-user=slavemaster-password=10086# Default to using old password format for compatibility with mysql 3.x# clients (those using the mysqlclient10 compatibility package).old_passwords=1[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.pid

5、在master上查看主库状态

mysql> show master status;+------------------+----------+--------------+------------------+| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |+------------------+----------+--------------+------------------+| mysql-bin.000001 |     7156 |              |                  |+------------------+----------+--------------+------------------+1 row in set (0.00 sec)

6、查看从库状态

mysql> slave stop;mysql> change master to master_host='192.168.0.9',master_user='slave',master_password='10086',master_log_file='mysql-bin.000001',master_log_pos=7156;mysql> slave startmysql> show slave status\G*************************** 1. row ***************************             Slave_IO_State: Waiting for master to send event                Master_Host: 192.168.0.9                Master_User: slave                Master_Port: 3306              Connect_Retry: 60            Master_Log_File: mysql-bin.000001        Read_Master_Log_Pos: 7156             Relay_Log_File: mysqld-relay-bin.000002              Relay_Log_Pos: 7068      Relay_Master_Log_File: mysql-bin.000001           Slave_IO_Running: Yes          Slave_SQL_Running: Yes            Replicate_Do_DB:        Replicate_Ignore_DB:         Replicate_Do_Table:     Replicate_Ignore_Table:    Replicate_Wild_Do_Table:Replicate_Wild_Ignore_Table:                 Last_Errno: 0                 Last_Error:               Skip_Counter: 0        Exec_Master_Log_Pos: 7156            Relay_Log_Space: 7068            Until_Condition: None             Until_Log_File:              Until_Log_Pos: 0         Master_SSL_Allowed: No         Master_SSL_CA_File:         Master_SSL_CA_Path:            Master_SSL_Cert:          Master_SSL_Cipher:             Master_SSL_Key:      Seconds_Behind_Master: 01 row in set (0.00 sec)

7、测试master建立test10测试库，创建一个abc表，插入数据，查看是否同步到slave上

mysql> create database test10;Query OK, 1 row affected (0.00 sec)mysql> use test10;Database changedmysql> create table abc (name char,age int);Query OK, 0 rows affected (0.01 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.01 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.02 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.01 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.02 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.01 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.01 sec)mysql> insert into abc (name,age) values ('zhang',22);Query OK, 1 row affected, 1 warning (0.01 sec)mysql> insert into abc (name,age) values ('zhang',22);

查看slave是否有相同的信息

mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || test               || test1              || test10             |+--------------------+5 rows in set (0.00 sec)mysql> use test10Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> select * from abc;+------+------+| name | age  |+------+------+| z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 || z    |   22 |+------+------+

成功
