如题，mysql数据库的中文显示乱码：
先看下原来数据库里的字符编码：
mysql> show variables like ‘%character_set%‘; -------------------------- ---------------------------- | Variable_name | Value | -------------------------- ---------------------------- | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | latin1 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | -------------------------- ---------------------------- 8 rows in set (0.00 sec)
修改配置文件：
[[email protected]_0_14_centos ~]# vi /etc/my.cnf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 #字符集指定为utf8 character-set-server=utf8 #字符集的校对规则为utf8 collation-server=utf8_general_ci #存储引擎 default-storage-engine=InnoDB [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [client] default-character-set=utf8 [mysql] default-character-set=utf8
标黄的都是新增的配置，接着保存好配置文件，重启mysql让设置生效：
[[email protected] ~]# service mysqld restart Stopping mysqld: [ OK ] Starting mysqld: [ OK ]
登陆mysql，看下存储引擎：
mysql> show variables like ‘%storage_engine%‘; ---------------- -------- | Variable_name | Value | ---------------- -------- | storage_engine | InnoDB | ---------------- -------- 1 row in set (0.00 sec)
再看字符编码：
mysql> show variables like ‘%character_set%‘; -------------------------- ---------------------------- | Variable_name | Value | -------------------------- ---------------------------- | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | -------------------------- ---------------------------- 8 rows in set (0.00 sec)
我们发现还有一个character_set_database是ISO-8859-1，改掉：
mysql> alter database `prize` character set utf8 collate utf8_general_ci; Query OK, 1 row affected (0.00 sec) mysql> show variables like ‘%character_set%‘; -------------------------- ---------------------------- | 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/ | -------------------------- ---------------------------- 8 rows in set (0.00 sec)
现在把老的乱码数据删掉，重新插入就可以展示了：
