实例主机：
dbasky=192.168.1.120
dbaskyback=192.168.1.121
目的：dbaskyback的主机去同步dbasky主机test库上的数据
安装mysql
| 以下是代码片段： [root@dbasky]#wget ftp://ftp.cronyx.ru/pub/FreeBSD/ports/distfiles/mysql-5.0.45.tar.gz [root@dbasky]#cd /usr/local/mysql-5.0.45 [root@dbasky]#groupadd mysql [root@dbasky]#useradd -g mysql mysql [root@dbasky]#mkdir /opt/mysql-data [root@dbasky]#CFLAGS="-O3 " CXX=gcc CXXFLAGS="-O3 -felide-constructors \\ -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local/mysql --enable-assembler --with-charset=utf8 --with-extra-charsets=gbk,gb2312,latin1 --localstatedir=/opt/mysql-data --with-mysqld-user=mysql --enable-large-files --with-big-tables --without-debug --enable-thread-safe-client --with-fast-mutexes --with-innodb [root@dbasky]#make [root@dbasky]#make install [root@dbasky]#cd /etc [root@dbasky]#rz my.cnf [root@dbasky]#chown -R mysql .

在dbasky机器上
建立用户
| 以下是代码片段： mysql>create database test; mysql>grant all on *.* to xu@\’192.168.1.121\’ identified by \’123456\’; [root@dbasky]#vi /etc/my.cnf server-id=1 #为master log-bin=/var/log/mysql/mysql.log |
添加
| 以下是代码片段： binlog-do-db=test #要同步的数据库名字 |
重新启动mysql
用 mysql>show master status 查看
在dbaskyback机器上
| 以下是引用片段： dbaskyback#vi /etc/my.cnf server-id=2 #为slave master-host=192.168.1.120 master-user=xu master-password=123456 master-port=3306 master-connect-retry=60 #间隔60秒重新设置 replicate-do-db=test |
用mysql>show slave status 看同步情况，如果有错误也可以看得出来.
