四、配置主从数据库(master库A在192.168.1.223上，slave库B在192.168.1.222上，slave库C在192.168.1.224)
1、登录master，增加slave用的用户
GRANT REPLICATION SLAVE ON *.* TO 'slave_a'@'192.168.1.222' IDENTIFIED BY '123456'
GRANT REPLICATION SLAVE ON *.* TO 'slave_b'@'192.168.1.224' IDENTIFIED BY '123456'
注：开放master的端口，允许slave远程连接
# vi /etc/sysconfig/iptables
============================
在icmp-host-prohibited前增加：-A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
============================
# service iptables restart
2、修改MySQL配置文件
a)master
# vi /etc/my.cnf
=============
[mysqld]
server-id = 1
log_bin = mysql-bin
read-only = 0
binlog-do-db = test # 多个写多行
binlog-ignore-db = mysql #多个写多行
binlog-ignore-db = information_schema
=============
b)slave，配置每个slave
# vi /etc/my.cnf
[mysqld]
server-id = 2
log_bin = mysql-bin
read-only = 1
replicate-do-db = test
replicate-ignore-db = mysql
replicate-ignore-db = information_schema
=============
3、启动slave后执行(各台slave操作类似)：
CHANGE MASTER TO MASTER_HOST = '192.168.1.223', MASTER_USER = 'slave_a', MASTER_PASSWORD = '123456', MASTER_LOG_FILE = 'mysql-bin.000001', MASTER_LOG_POS = 107; 通过在master上SHOW MASTER STATUS 来得到MASTER_LOG_FILE和MASTER_LOG_POS的值
SLAVE START;
SHOW SLAVE STATUS \G; 查看是否同步上
4、登录master，增删改数据后看下各slave是否正常同步到
五、测试
1、简单测试
在主从库上都建立账号mysqlproxyadm
# GRANT SELECT ON *.* TO 'mysqlproxyadm'@'192.168.1.224' IDENTIFIED BY '123456' # GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,ALTER ON *.* TO 'mysqlproxyadm'@'192.168.1.224' IDENTIFIED BY '123456' # GRANT SELECT ON *.* TO 'mysqlproxyadm'@'192.168.1.224' IDENTIFIED BY '123456' 执行读写操作简单测试是否读写分离(观察主从库日志文件，需要打开my.cnf的log = log-filename) ./mysql -h192.168.1.224 -umysqlproxyadm -p123456 -P4040
