查看mysql數(shù)據(jù)編碼
登錄mysql服務(wù)，查看mysql數(shù)據(jù)庫(kù)默認(rèn)的編碼
mysql> show variables like 'character%';
+--------------------------+-------------------------------------------------+

+--------------------------+-------------------------------------------------+
| character_set_client | gbk |
| character_set_connection | gbk |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | gbk |
| character_set_server | latin1 |

可以看出database和server都采用了latin1編碼，不支持中文，我們需要把它修改為utf-8。
除了這兩個(gè)，其它的如下
| 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 | E:\0Develop\mysql-5.7.15-winx64\share\charsets\

設(shè)置mysql數(shù)據(jù)庫(kù)編碼
在mysql安裝目錄下，將 my-default.ini 復(fù)制一分保存為 my.ini
做如下修改
主要看紅色框里的內(nèi)容
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
[mysql]
default-character-set = utf8
[mysql.server]
default-character-set = utf8
[mysqld_safe]
default-character-set = utf8
[client]
default-character-set = utf8

然后刪除你當(dāng)前的mysql服務(wù)，再重新注冊(cè)mysql服務(wù)
注：一定要以管理員的權(quán)限運(yùn)行dos命令，且cd到mysql安裝目錄下的bin目錄，再注冊(cè)mysql服務(wù)
C:\Windows\system32>sc delete mysql
[SC] DeleteService 成功
C:\Windows\system32>e: cd
E:\>cd E:\0Develop\mysql-5.7.15-winx64\bin
E:\0Develop\mysql-5.7.15-winx64\bin>mysqld --install mysql --defaults-file="E:\0Develop\mysql-5.7.15-winx64\my.ini"
The service already exists!
The current server installed: E:\0Develop\mysql-5.7.15-winx64\bin\mysqld MySQL
E:\0Develop\mysql-5.7.15-winx64\bin>net stop mysql
MySQL 服務(wù)正在停止..服務(wù)名無(wú)效。
請(qǐng)鍵入 NET HELPMSG 2185 以獲得更多的幫助。
E:\0Develop\mysql-5.7.15-winx64\bin>mysqld --install mysql --defaults-file="E:\0Develop\mysql-5.7.15-winx64\my.ini"
Service successfully installed.

結(jié)果
啟動(dòng)服務(wù)，查看編碼
C:\Windows\System32>net start mysql
mysql 服務(wù)正在啟動(dòng) .
mysql 服務(wù)已經(jīng)啟動(dòng)成功。
C:\Windows\System32>mysql -u root

二、重新啟動(dòng)MySql服務(wù)即可
三、查看mysql字符集 (默認(rèn)情況下，mysql的字符集是latin1)
1. 啟動(dòng)mysql后，以root登錄mysql
2. 輸入命令
show variables like 'character%';
