1.确认并设置MySql的数据库的编码（注意下面橘色字体） mysql> status -------------- mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1 Connection id: 2 Current database: school Current user: [email protected] SSL: Not in use Current pager: stdout Using outfile: ‘‘ Using delimiter: ; Server version: 5.1.73 Source distribution Protocol version: 10 Connection: Localhost via UNIX socket Server characterset: utf8 Db characterset: utf8 Client characterset: latin1 Conn. characterset: latin1 UNIX socket: /var/lib/mysql/mysql.sock Uptime: 1 min 8 sec Threads: 1 Questions: 13 Slow queries: 0 Opens: 17 Flush tables: 1 Open tables: 10 Queries per second avg: 0.191 --------------
2.修改方法 首先进入数据库mysql -uroot -p123 mysql>use school mysql> alter database school character set utf8; mysql> alter database school character set utf8 collate utf8_general_ci;
mysql> alter table books character set utf8 collate utf8_general_ci; 3.vim /etc/my.conf //编辑修改mysql配置文件 [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 character-set-server = utf8 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [client] default-character-set=utf8 [mysql] default-character-set=utf8 4.以上保存后重启数据库 [[email protected] ~]# /etc/init.d/mysqld restart 停止 mysqld： [确定] 正在启动 mysqld： [确定] 5.进入mysql查看字符集 mysql> show variables like "%char%"; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec) mysql> show variables like "%colla%"; +----------------------+-----------------+ | Variable_name | Value | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database | utf8_general_ci | | collation_server | utf8_general_ci | +----------------------+-----------------+ 3 rows in set (0.00 sec)
mysql> select * from books; +-----+---------------------------------------------------------+---------+-----------------------------------+-------+------------+-----------+-------------+ | bId | bName | bTypeId | publishing | price | pubDate | author | ISBN | +-----+---------------------------------------------------------+---------+-----------------------------------+-------+------------+-----------+-------------+ | 1 | 网站制作直通车 | 2 | 电脑爱好者杂志社 | 34 | 2004-10-01 | 苗壮 | 7505380796 | | 2 | 黑客与网络安全 | 6 | 航空工业出版社 | 41 | 2002-07-01 | 白立超 | 7121010925 | | 3 | 网络程序与设计－asp | 2 | 北方交通大学出版社 | 43 | 2005-02-01 | 王玥 | 75053815x | | 4 | pagemaker 7.0短期培训教程 | 9 | 中国电力出版社 | 43 | 2005-01-01 | 孙利英 | 7121008947 | | 5 | 黑客攻击防范秘笈 | 6 | 北京腾图电子出版社 | 44 | 2003-06-29 | 赵雷雨 | 7120000233 | | 6 | Dreamweaver 4入门与提高 | 2 | 清华大学出版社 | 44 | 2004-06-01 | 岳玉博 | 7505397699 |
一、避免创建数据库及表出现中文乱码和查看编码方法
1、创建数据库的时候：CREATE DATABASE `test`
CHARACTER SET ‘utf8‘
COLLATE ‘utf8_general_ci‘;
2、建表的时候 CREATE TABLE `database_user` (
`ID` varchar(40) NOT NULL default ‘‘,
`UserID` varchar(40) NOT NULL default ‘‘,
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
即建库和建表时都使用相同的编码格式。
查看school数据库的编码格式:
mysql> show create database school; +----------+-----------------------------------------------------------------+ | Database | Create Database | +----------+-----------------------------------------------------------------+ | school | CREATE DATABASE `school` /*!40100 DEFAULT CHARACTER SET utf8 */ | +----------+-----------------------------------------------------------------+ 1 row in set (0.00 sec)
查看books表的编码格式
1 mysql> use school 2 Reading table information for completion of table and column names 3 You can turn off this feature to get a quicker startup with -A 4 5 Database changed 6 mysql> show create table books; 7 +-------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 8 | Table | Create Table | 9 +-------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 10 | books | CREATE TABLE `books` ( 11 `bId` int(4) NOT NULL AUTO_INCREMENT, 12 `bName` varchar(255) DEFAULT NULL, 13 `bTypeId` enum(‘1‘,‘2‘,‘3‘,‘4‘,‘5‘,‘6‘,‘7‘,‘8‘,‘9‘,‘10‘) DEFAULT NULL, 14 `publishing` varchar(255) DEFAULT NULL, 15 `price` int(4) DEFAULT NULL, 16 `pubDate` date DEFAULT NULL, 17 `author` varchar(30) DEFAULT NULL, 18 `ISBN` varchar(255) DEFAULT NULL, 19 PRIMARY KEY (`bId`) 20 ) ENGINE=MyISAM AUTO_INCREMENT=45 DEFAULT CHARSET=utf8 | 21 +-------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 22 1 row in set (0.00 sec)
