Linux环境下默认登录mysql之后show variables like
Linux环境下默认登录mysql之后show variables like '%character%', 出现
mysql> show variables like '%character%';
-------------------------- ----------------------------
| Variable_name | Value |
修改/etc/mysql/my.cnf
在[client]下增加default-character-set=utf8
在[mysqld]下增加default-character-set=utf8
同时加上init_connect='SET NAMES utf8' (设定连接mysql数据库时使用utf8编码，以让mysql数据库为utf8运行)
重新启动mysql，执行:sudo /etc/init.d/mysql stop 然后sudo /etc/init.d/mysql start
mysql> show variables like '%character%';
-------------------------- ----------------------------
| 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/ |
-------------------------- ----------------------------
即使做了以上修改如果直接数据库再创建表，然后存入中文，取出来的会是问号。解决的办法是：
创建数据库的时候指明默认字符集为utf8，如：
create database test default character set utf8;
