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~!~!

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
1
|
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:
1
|
/etc/init.d/mysql start |
如果能重启那么再次查看数据库编码:

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 :
1
|
mysql -u root -p |
则会抛出异常:
1
|
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)。。。。。
1
|
sudo /etc/init .d /mysql status |
查看mysql的状态:mysql respawn/post-start, (post-start) process 55665
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ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
的解决办法。
答案:
[ mysqld ] 下的 default-character-set=utf8'
改成character_set_server=utf8
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 show create database bangjob;
展示之前创建的数据编码依旧是latin1
