领导突然让做主从服务器，mysq让用5.5版本的，以前搭建过5.1，本来感觉很easy，哪知道却有很大区别调试了好长时间，终于弄好了！

mysql5.5安装起来也和以前的大不一样，以前的configure已经习惯了，现在突然来了个cmake。。。。

环境介绍：

centos 5.5系统，mysql版本为mysql-5.5.27

192.168.1.6　　主服务器

192.168.1.4　　从服务器

首先开始主服务器上的操作

标红位置为修改区域

[root@localhost ~]# grep -v ^# /etc/my.cnf |grep -v ^$

[client]

port            = 3306

socket          = /tmp/mysql.sock

[mysqld]

port            = 3306

socket          = /tmp/mysql.sock

skip-external-locking

key_buffer_size = 256M

max_allowed_packet = 1M

table_open_cache = 256

sort_buffer_size = 1M

read_buffer_size = 1M

read_rnd_buffer_size = 4M

myisam_sort_buffer_size = 64M

thread_cache_size = 8

query_cache_size= 16M

thread_concurrency = 8

binlog-do-db=beifen

binlog-do-db=bucuo

binlog-ignore-db=bubeifen

log-bin=mysql-bin

binlog_format=mixed

server-id       = 1

[mysqldump]

quick

max_allowed_packet = 16M

[mysql]

no-auto-rehash

[myisamchk]

key_buffer_size = 128M

sort_buffer_size = 128M

read_buffer = 2M

write_buffer = 2M

[mysqlhotcopy]

interactive-timeout

然后创建一个可以远程登陆到服务器上的一个数据库帐号，赋予权限

mysql> grant replication slave,reload,super on *.* to 'tiger'@'%' identified by '123456';

Query OK, 0 rows affected (0.05 sec)

修改完配置文件后的必要操作，重启服务

[root@localhost ~]# service mysqld restart

Shutting down MySQL.[确定]

Starting MySQL..[确定]

[root@localhost ~]# mysql -uroot -p

主服务器已经配置好了，下面开始从服务器的配置

//然后在主服务器上的beifen数据库中创建一个user表，发现从服务器上的beifen数据库也有了user表，OK，主从服务器搭建成功！
