`4`	`/etc/init.d/mysql??????????????#启动脚本`

修改字符集和数据存储路径

配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码utf-8.

[html]?view plaincopy

[client]??
password????????=?123456??
port????????????=?3306??
default-character-set=utf8??
[mysqld]??
port????????????=?3306??
character_set_server=utf8??
character_set_client=utf8??
collation-server=utf8_general_ci??
#(注意linux下mysql安装完后是默认：表名区分大小写，列名不区分大小写；?0：区分大小写，1：不区分大小写)??
lower_case_table_names=1??
#(设置最大连接数，默认为?151，MySQL服务器允许的最大连接数16384;?)??
max_connections=1000??
[mysql]??
default-character-set?=?utf8??

查看字符集

show variables like '%collation%';

show variables like '%char%';
