linxu下Mysql 修改默认的字符集

rpm包安装的Mysql在/etc/my.cnf中会有mysql的主配置信息项·  如果该文件被修改的乱七八糟的可以从/usr/share/mysql下根据机器的内存拷贝相应的my-xxx.cnf文件到/etc下,并重命名为my.cnf

 

 

 # The following options will be passed to all MySQL clients
[client]
#password       = your_password
port            = 3306
socket          = /var/lib/mysql/mysql.sock

default-character-set = utf8  (新加入的)

 

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port            = 3306
socket          = /var/lib/mysql/mysql.sock

default-character-set = utf8  (新加入的)
skip-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K

 

 保存文件退出，重启mysql;

 

service mysql restart;

 

进入mysql执行如下命令；

 

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
