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 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. [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%';
