mysql 5.6 win7X64 配置

下載好.zip文件安裝好之後，默認的數據庫格式不是utf8，運行mysql命令，之後運行mysql->show variables like '%char%';出現下面這樣的：

這就是導致jsp頁面utf8編碼但是中文到數據庫就是亂碼的原因。

需要mysql根目錄下複製my-default.ini到本目錄my.ini，之後再裏面增加下面的紅色字體內容：

[mysql]
default-character-set=utf8

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# 設置mysql的安裝目錄
basedir = D:/tools/mysql/mysql-5.6.11-winx64

# 設置mysql數據庫的數據存放目錄
datadir = D:/tools/mysql/mysql-5.6.11-winx64/data
# port = .....
# server_id = .....
character-set-server=utf8

再重新運行上面的指令查看mysql編碼如下：

全部都是utf8了，之後jsp就可以正常提交中文到mysql也能正常顯示了。
