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

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)

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：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)。
