數據庫mysql實現讀寫分離應用

參考：http://www.cnblogs.com/DavidYan/articles/2531181.html

1,建立用戶

grant replication slave on . to 'rep1'@'192.168.%.%' identified by 'fuhan'

2，定義日誌

主服務器「

在[mysqld]下面增長下面幾行代碼

server-id=1 //給數據庫服務的惟一標識，通常爲你們設置服務器Ip的末尾號

log-bin=master-bin

log-bin-index=master-bin.index

查看日誌

show master status

次服務器：1 [mysqld]

server-id=2

relay-log-index=slave-relay-bin.index

relay-log=slave-relay-bin

change master to master_host='192.168.242.1',

master_user='rep1',

master_password='fuhan',

master_log_file='mysql-bin.000002',

master_log_pos=1168;

單次修改：CHANGE MASTER TO MASTER_LOG_FILE='master-bin.000004',MASTER_LOG_POS=120;

查看配置

show slave status\G

報錯:

Slave can not handle replication events with the checksum that master is configured to log;

解決，主機mysqld裏面設置:

flush logs;

binlog_checksum =none
