[root@localhost ~]# chkconfig --list | grep mysql
8, MySQL的默认安装位置
/var/lib/mysql/ #数据库目录/usr/share/mysql #配置文件目录/usr/bin #相关命令目录/etc/init.d/mysql #启动脚本

[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
show variables like '%collation%'; 10, 查看字符集
