发现问题 最近一段时间学习Django,在进行与MySQL数据联合使用的插入数据的时候遇到下边的问题: /usr/local/lib/python2.7/dist-packages/Django-1.11.dev20170117002028-py2.7.egg/django/db/backends/mysql/base.py:109: Warning: Incorrect string value: '\xE6\x88\x90\xE5\x8A\x9F...' for column 'json' at row 1 return self.cursor.execute(query, args) [07/Feb/2017 12:15:21] "GET /index/ HTTP/1.1" 200 250 中文无法插入MySQL数据库~!~! 查看数据库编码 mysql> show create database bangjob; +----------+--------------------------------------------------------------------+ | Database | Create Database | +----------+--------------------------------------------------------------------+ | bangjob | CREATE DATABASE `bangjob` /*!40100 DEFAULT CHARACTER SET latin1 */ | +----------+--------------------------------------------------------------------+ 1 row in set (0.00 sec) mysql> show variables like'%char%'; +--------------------------+----------------------------+ | 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 | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec) 修改数据库编码 mysql> set character_set_database=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_server=utf8; Query OK, 0 rows affected (0.00 sec) 查看修改后的结果 mysql> show variables like'%char%'; +--------------------------+----------------------------+ | 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) 这时候继续插入就没有任何问题了。 如果真的是这样简单就好了,因为这样的修改作者在重启MySQL的后设置失效!!! 继续寻找其它方法 sudo gedit /etc/mysql/my.cnf 在my.cnf文件的对应节点添加一下信息: [client] default-character-set=utf8 [mysqld] default-character-set=utf8 [mysql] default-character-set=utf8 然后重启MySQL: /etc/init.d/mysql start 如果能重启那么再次查看数据库编码: mysql> show variables like "%char%"; +--------------------------+----------------------------+ | 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 (0.01 sec) 如果真的时这样就好了,事情的发生总是不像想象的那么简单: 在重启MySQL服务的时候发现一直处于等待状态(PS:猜测发生了死锁什么的),这个时候执行 : mysql -u root -p 则会抛出异常: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) 我就是想修改一下编码而已,为什么这么苦->->->->->!!! 解决这个问题的时候试过好多方法(重启,恢复)。。。。。 sudo /etc/init.d/mysql status 查看mysql的状态: 这些方式不能解决问题,还是从日志开始吧… 找到日至文件 /var/log/mysql/error.log 继续找 答案: [ mysqld ] 下的 好了,终于可以重启MySQL了,并且重启后设置的编码依旧生效。 当然之前创建的数据库需要重新创建T_T 因为 总结 以上就是这篇文章的全部内容了,希望本文的内容对大家的学习或者工作能带来一定的帮助,如果有疑问大家可以留言交流。 |
