原因：修改mysql的默認(rèn)編碼不是UTF-8的
修改辦法：修改mysql的默認(rèn)字符集為utf8
方法：
1,檢查默認(rèn)安裝的mysql的字符集
mysql> show variables like '%char%';
+--------------------------+--------------------------------------------------------+
| Variable_name ? ? ? ? ? ?| Value ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?|
+--------------------------+--------------------------------------------------------+
| character_set_client ? ? | utf8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |
| character_set_connection | utf8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

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(huì)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(jìn)程，不然會(huì)遇到mysql的sock不能連接的問題。
2，關(guān)閉mysqld后臺(tái)進(jìn)程
系統(tǒng)偏好設(shè)置里面控制mysqld，避免了去找mysqld安裝位置的麻煩。
點(diǎn)擊 Stop MySQL Server
3，查看一下support-files文件夾(Finder下"前往文件夾";路徑:/usr/local/mysql/support-files) 里面有沒有my-default.cnf或my.cnf文件...如果有則直接打開添加
在[client] 在下面添加
default-character-set=utf8 默認(rèn)字符集為utf8
在[mysqld] 添加
default-character-set=utf8 默認(rèn)字符集為utf8
init_connect='SET NAMES utf8' （設(shè)定連接mysql數(shù)據(jù)庫時(shí)使用utf8編碼，以讓mysql數(shù)據(jù)庫為utf8運(yùn)行）
修改好后，重新啟動(dòng)mysql查看當(dāng)前數(shù)據(jù)編碼格式。

若終端出現(xiàn)如上樣式則OK了,否則繼續(xù)往下看:
3.2 support-files文件夾里面沒有my-default.cnf或my.cnf文件,那么就要在/etc下新建my.cnf
$ cd /etc
$ sudo vim my.cnf
3.3 進(jìn)行完上步操作后會(huì)進(jìn)入vim模式,此時(shí)復(fù)制(***文本)的內(nèi)容粘貼進(jìn)去,,(不包含 ? ***文本 );
3.4 粘貼成功后注意看vim的第一行"#"有沒有丟掉(本人就丟過~~哈哈~),都OK的話點(diǎn)esc退出編輯,
:wq!?--保存后強(qiáng)制退出.[附幾個(gè)編輯命令:dd?刪除光標(biāo)所在行;dw?刪除一個(gè)字(word);x?刪除當(dāng)前字符].

# Replication Slave (comment out master section to use this)??
#??
# To configure this host as a replication slave, you can choose between??
# two methods :??
#??
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -??
# the syntax is:??
#??
# CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,??
# MASTER_USER=, MASTER_PASSWORD= ;??
#??
# where you replace , , by quoted strings and??
# by the master's port number (3306 by default).??
#??
# Example:??
#??
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,??
# MASTER_USER='joe', MASTER_PASSWORD='secret';??
#??
# OR??
#??
# 2) Set the variables below. However, in case you choose this method, then??
# start replication for the first time (even unsuccessfully, for example??
# if you mistyped the password in master-password and the slave fails to??
# connect), the slave will create a master.info file, and any later??
# change in this file to the variables' values below will be ignored and??
# overridden by the content of the master.info file, unless you shutdown??
# the slave server, delete master.info and restart the slaver server.??
# For that reason, you may want to leave the lines below untouched??
# (commented) and instead use CHANGE MASTER TO (see above)??
#??
# required unique id between 2 and 2^32 - 1??
# (and different from the master)??
