最近一段時間學習Django，在進行與MySQL數(shù)據(jù)聯(lián)合使用的插入數(shù)據(jù)的時候遇到下邊的問題：

/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

中文無法插入MySQL數(shù)據(jù)庫～！～！

查看數(shù)據(jù)庫編碼

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)

修改數(shù)據(jù)庫編碼

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)

查看修改后的結(jié)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)

這時候繼續(xù)插入就沒有任何問題了。如果真的是這樣簡單就好了，因為這樣的修改作者在重啟MySQL的后設(shè)置失效?。?！

繼續(xù)尋找其它方法

sudo gedit /etc/mysql/my.cnf

在my.cnf文件的對應(yīng)節(jié)點添加一下信息：

[client]default-character-set=utf8[mysqld]default-character-set=utf8[mysql]default-character-set=utf8

然后重啟MySQL：

/etc/init.d/mysql start

如果能重啟那么再次查看數(shù)據(jù)庫編碼：

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)

如果真的時這樣就好了，事情的發(fā)生總是不像想象的那么簡單：在重啟MySQL服務(wù)的時候發(fā)現(xiàn)一直處于等待狀態(tài)（PS：猜測發(fā)生了死鎖什么的），這個時候執(zhí)行mysql -u root -p則會拋出異常ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)。我就是想修改一下編碼而已，為什么這么苦->->->->->!!!

解決這個問題的時候試過好多方法（重啟，恢復）。。。。。

sudo /etc/init.d/mysql status

查看mysql的狀態(tài)：mysql respawn/post-start, (post-start) PRocess 55665

這些方式不能解決問題，還是從日志開始吧… 找到日至文件 /var/log/mysql/error.log 某一段日志內(nèi)容.png
