對(duì)于mysql中文mysql（我的是ubuntu系統(tǒng)），在網(wǎng)上看了很多解決方案，期間也走了不少?gòu)澛罚韵胫鶕?jù)自己的解決之路寫(xiě)一篇文章分享給有需要的朋友們，所以這篇文章主要介紹了如何解決ubuntu下mysql中文亂碼問(wèn)題的相關(guān)資料,需要的朋友可以參考借鑒。
發(fā)現(xiàn)問(wèn)題
最近一段時(shí)間學(xué)習(xí)mysql，在進(jìn)行與MySQL數(shù)據(jù)聯(lián)合使用的mysql的時(shí)候遇到下邊的問(wèn)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:?'xE6x88x90xE5x8Ax9F...'? 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(wú)法插入MySQL數(shù)據(jù)庫(kù)～！～！
查看數(shù)據(jù)庫(kù)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(kù)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(shí)候繼續(xù)插入就沒(méi)有任何問(wèn)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
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：
[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(kù)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(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mysql（PS：猜測(cè)發(fā)生了死鎖什么的），這個(gè)時(shí)候執(zhí)行 ：
mysql?-u?root?-p
則會(huì)mysql：
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(wèn)題的時(shí)候試過(guò)好多方法（重啟，恢復(fù)）。。。。。
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(wèn)題，還是從日志開(kāi)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(kù)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)
