mac下修改mysql默认字符集为utf8
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1、首先檢查默認安裝的字符集?
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/local/mysql-5.6.23-osx10.8-x86_64/share/charsets/?|??+--------------------------+--------------------------------------------------------+??8?rows?in?set?(0.00?sec)??
character_set_database和character_set_server依然是latin1的字符集，也就是說mysql后續創建的表都是latin1字符集的，不是utf8，會造成一些麻煩。所以有必要修改my.cnf，在修改my.cnf之前一定要關閉mysql進程，不然會遇到mysql的sock不能連接的問題。

2、查看是否有my.cnf文件在/etc/目錄下
ls?-al?/etc/?? 檢查了一下，發現本機沒有my.cnf，查看了很多資料，他們說可以去/usr/local/mysql的安裝目錄下找到support-files，復制下面格式類似my-**.cnf的文件到/etc/目錄下即可。命令如下：?
cp?/usr/local/mysql/support-files/my-default.cnf?/etc/?? 3、修改/etc/my-default.cnf文件名為my.cnf，并修改里面的配置
cat?/etc/my.cnf?? 查看配置文件的內容
ls?-l?/etc/my.cnf?? 查看文件的讀寫權限，如果為644（rw- r-- r--）則改為(664) (rw- rw- r--)
如果改為(666)(rw- rw- rw-)則修改以后配置文件不會生效。下面詳細講解為什么不會生效。
sudo?chmod?664?/etc/my.cnf?? 輸入密碼即可。?
4、修改配置文件內容
vi?/etc/my.cnf?? 在文件最上面加上?
[client]??default-character-set=utf8? 在[mysqld]下增加
character-set-server=utf8?? 鍵入:wq!保存并退出
5、重新查看編碼集
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/local/mysql-5.6.23-osx10.8-x86_64/share/charsets/?|??+--------------------------+--------------------------------------------------------+??8?rows?in?set?(0.00?sec)?
