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(xù)創(chuàng)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(guān)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(fā)現(xiàn)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(fù)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(nèi)容

ls?-l?/etc/my.cnf??

查看文件的讀寫權(quán)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(nèi)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)?
