MySQL5.5读写分离配置

摘要:很早之前搭建过mysql读写分离架构,然后今天研究mysql数据库主从不同步的问题,要再搭一套这样的环境,发现按照之前写的怎么搭都不成功。经度娘,原来Mysql版本从5.1.7以后开始就不支持“master-host”等参数,于是就只有再记录一套了~
很早之前搭建过mysql读写分离架构(原文:http://www.webyang.net/Html/web/article_89.html),然后今天研究mysql数据库主从不同步的问题,要再搭一套这样的环境,发现按照之前写的怎么搭都不成功。经度娘,原来Mysql版本从5.1.7以后开始就不支持“master-host”等参数,于是就只有再记录一套了~

一、服务器配置
主库:192.168.204.132
vim /etc/my.cnf
server-id= 1
log-bin=mysql-bin
binlog_format=mixed
#需要同步的二进制数据库名
binlog-do-db=test
#不同步的二进制数据库名
binlog-ignore-db=mysql
binlog-ignore-db=performance_schema
#可选参数
sync-binlog = 1
#日志保留天数
expire_logs_days = 7
从库:192.168.204.134
vim /etc/my.cnf
server-id=2
log-bin=mysql-bin
binlog_format=mixed
#不需要复制的数据库
replicate-ignore-db=mysql
replicate-ignore-db=performance_schema
#需要复制的数据库
replicate-do-db=test
#可选参数
sync-binlog = 1
expire_logs_days = 7
二、设置主从
主库:
mysql> SHOW MASTER STATUS;
+------------------+----------+--------------+--------------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB         |
+------------------+----------+--------------+--------------------------+
| mysql-bin.000026 |      302 | test         | mysql,performance_schema |
+------------------+----------+--------------+--------------------------+
mysql>GRANT REPLICATION SLAVE ON *.* TO 'root'@'192.168.204.134' IDENTIFIED BY '123456';
mysql>FLUSH PRIVILEGES;

从库:
mysql> CHANGE MASTER TO MASTER_HOST='192.168.204.132',MASTER_USER='root', MASTER_PASSWORD='123456',MASTER_LOG_FILE='mysql-bin.000026',MASTER_LOG_POS=302;
#上面参数注意对照主库
mysql> slave stop;
mysql> slave start;
mysql> show slave status \G;
