ubuntu下向数据库中添加数据乱码

ubuntu中向数据库中添加数据乱码

1.先查看数据库编码格式

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/ |
+--------------------------+----------------------------+

此为正常，一般 character_set_database 和 character_set_server 的编码格式都是latin1

2.如果编码格式不是以上格式

• 打开mysql的my.cnf文件（次文件在/etc/mysql/）

• 在最下面输入一下内容

  [client]
  port = 3306
  socket = /var/lib/mysql/mysql.sock
  default-character-set=utf8
  
  [mysqld]
  port = 3306
  socket = /var/lib/mysql/mysql.sock
  character-set-server=utf8
  
  [mysql]
  no-auto-rehash
  default-character-set=utf8
  

• 在登录mysql，输入SHOW VARIABLES LIKE 'character%';查看数据库编码格式。

mysql> SHOW VARIABLES LIKE 'character%';
