1、查看当前字符集：
SHOW CHARACTER SET;
2、删除mysql相关目录
rm -rf /usr/local/mysql/*     安装目录
rm -rf /var/lib/mysql/mysql   数据库目录
2、重新编译
./configure --prefix=/usr/local/mysql --sysconfdir=/etc --localstatedir=/var/lib/mysql --with-charset=gbk --with-collation=gbk_chinese_ci --with-extra-charsets=complex
make clean
make
make install
3、安装后工作：

停止mysql服务。

Pkill -9 mysql

cd /var/lib/mysql/

先把master.info和relay有关的日志全部删掉

rm –rf *.bin 

rm -rf mysql-bin.*

/usr/local/mysql/bin/mysql_install_db
chown -R mysql /var/lib/mysql
cp /usr/local/src/mysql-5.1.55/support-files/my-medium.cnf /etc/my.cnf
/usr/local/mysql/bin/mysqld_safe &
/usr/local/mysql/bin/mysqladmin -u root -p password '123456' 登录mysql试试：
