mysql-5.6.25免安裝版配置方法
一、首先要下載mysql-5.6.25-winx64，這裡就不提供下載了
二、解壓在“D:\Mysql“，可以根據自己實際情況選擇，MySQL的全路徑即為：“D:\Mysql\mysql-5.6.25-winx64”
三、配置my.ini檔案，將下面的配置儲存成my.ini，放在“D:\Mysql\mysql-5.6.25-winx64”下
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default locationduring install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[client]
port=3306
default-character-set=utf8
[mysqld]
port=3306
character_set_server=utf8
# 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
# These are commonly set, remove the # and set as required.
basedir = D:\Mysql\mysql-5.6.25-winx64
datadir = D:\Mysql\mysql-5.6.25-winx64\data
# port = .....
# server_id = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[WinMySQLAdmin]
D:\Mysql\mysql-5.6.25-winx64\bin\mysqld.exe
對於上面的配置路徑，要根據實際情況進行變化
四、配置環境變數
（1）右鍵單擊我的電腦->屬性->高階系統設定(高階)->環境變數
新建系統變數：MYSQL_HOME
值為MySQL的解壓路徑：D:\Mysql\mysql-5.6.25-winx64
（2）編輯環境變數path
在path的最前面加"%MYSQL_HOME%\bin;"，然後確定
注意如果新增在path的前面，要注意後面的分號，一定要有；如果新增path的前面，要注意前面一定要有分號
五、註冊MySQL服務
（1）以管理員身份執行命令提示符，切換到MySQL的解壓路徑下的bin目錄，D:\Mysql\mysql-5.6.25-winx64\bin>
（2）註冊服務：D:\Mysql\mysql-5.6.25-winx64\bin>mysqld install MySQL--defaults-file="D:\Mysql\mysql-5.6.25-winx64\my.ini"
（3）啟動MySQL服務
以管理員身份執行命令提示符，然後執行：net start mysql
六、修改MySQL root的密碼
C:\Users\user>mysql–uroot
mysql>show databases;
mysql>use mysql;
mysql>UPDATE user SET password=PASSWORD("123456")WHERE user='root';
mysql>FLUSH PRIVILEGES;
mysql>QUIT
七、幫助
（1）如果要解除安裝MySQL服務，D:\Mysql\mysql-5.6.25-winx64\bin>mysqld remove
（2）停止MySQL服務：net stop mysql
（3）在啟動MySQL服務的時候可能會遇到1067 的錯誤，可以檢查向下碟符配置的是否正確，或者更換路徑
