mysql安装后添加gbk字符集的方法

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

3、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

4、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：
/usr/local/mysql/bin/mysql -u root -p
