發(fā)現(xiàn)問題
最近一段時(shí)間學(xué)習(xí)Django，在進(jìn)行與MySQL數(shù)據(jù)聯(lián)合使用的插入數(shù)據(jù)的時(shí)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～！～！

這時(shí)候繼續(xù)插入就沒有任何問題了。
如果真的是這樣簡(jiǎn)單就好了，因?yàn)檫@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
|
1
|
sudo gedit /etc/mysql/my.cnf |
在my.cnf文件的對(duì)應(yīng)節(jié)點(diǎn)添加一下信息：
|

6
|
[client]default-character-set=utf8[mysqld]default-character-set=utf8[mysql]default-character-set=utf8 |
然后重啟MySQL：
|
1
|
/etc/init.d/mysql start |
如果能重啟那么再次查看數(shù)據(jù)庫編碼：

如果真的時(shí)這樣就好了，事情的發(fā)生總是不像想象的那么簡(jiǎn)單：
在重啟MySQL服務(wù)的時(shí)候發(fā)現(xiàn)一直處于等待狀態(tài)（PS：猜測(cè)發(fā)生了死鎖什么的），這個(gè)時(shí)候執(zhí)行 ：
|
1
|
mysql -u root -p |
則會(huì)拋出異常：
|
1
|
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) |
我就是想修改一下編碼而已，為什么這么苦->->->->->!!!
解決這個(gè)問題的時(shí)候試過好多方法（重啟，恢復(fù)）。。。。。
|
1
|
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
繼續(xù)找ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)的解決辦法。
答案：
[ mysqld ] 下的 default-character-set=utf8' 改成character_set_server=utf8
好了，終于可以重啟MySQL了，并且重啟后設(shè)置的編碼依舊生效。
當(dāng)然之前創(chuàng)建的數(shù)據(jù)庫需要重新創(chuàng)建T_T
因?yàn)?show create database bangjob;展示之前創(chuàng)建的數(shù)據(jù)編碼依舊是latin1
總結(jié)
以上就是這篇文章的全部?jī)?nèi)容了，希望本文的內(nèi)容對(duì)大家的學(xué)習(xí)或者工作能帶來一定的幫助，如果有疑問大家可以留言交流。
