<强>查看和设置MySQL数据库字符集
Liunx下修改MySQL字符集:
1。查找MySQL的cnf文件的位置
查找/- iname安全性的* .cnf
/usr/share/MySQL/my-innodb-heavy-4G.cnf
/usr/share/MySQL/my-large.cnf
/usr/share/MySQL/my-small.cnf
/usr/share/MySQL/my-medium.cnf
/usr/share/MySQL/my-huge.cnf
/usr/share/texmf/web2c/texmf.cnf
/usr/share/texmf/web2c/mktex.cnf
/usr/share/texmf/web2c/fmtutil.cnf
/usr/share/texmf/特克斯/xmltex xmltexfmtutil.cnf
/usr/share/texmf/特克斯/jadetex jadefmtutil.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-innodb-heavy-4G.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-large.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-small.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-medium.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-huge.cnf
2。拷贝small.cnf、my-medium.cnf my-huge.cnf, my-innodb-heavy-4G.cnf其中的一个到/etc下,命名
为my . cnf中所做cp/usr/share/mysql/my-medium.cnf/etc/my.cnf
3。
修改my . cnf中所做vi/etc/my.cnf
在[客户]下添加
default-character-set=utf8
在(mysqld)下添加
default-character-set=utf8
4。重新启动MySQL
root@bogon ~ #/etc/rc.d/init.d/mysql重启
关闭mysql(确定]
启动mysql。[确定]
[root@bogon ~) # mysql - u root - p
输入密码:
欢迎mysql的班长。命令结尾;或g。
你的MySQL连接id 1
服务器版本:5.1.22-rc-community-log MySQL Community Edition (GPL)
类型“帮助;”或“h”寻求帮助。“c”型缓冲。
5。查看字符集设置
mysql> show variables like 'collation_%';
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database | utf8_general_ci |
| collation_server | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.02 sec)
mysql> show variables like 'character_set_%';
+--------------------------+----------------------------+
| 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 (0.02 sec)
mysql>
其他的一些设置方法：
修改数据库的字符集
mysql>use mydb
mysql>alter database mydb character set utf-8;
创建数据库指定数据库的字符集
mysql>create database mydb character set utf-8;
通过配置文件修改:
修改/var/lib/mysql/mydb/db.选择
default-character-set=latin1
中的一个默认校对=latin1_swedish_ci
为
default-character-set=utf8
默认校对=utf8_general_ci
重起MySQL:
root@bogon ~ #/etc/rc.d/init.null
