mysql-5.7.12-winx64.zip Windows (x86, 64-bit), ZIP Archive版免安裝配置

 

1、下載免安裝版壓縮包

 

　　下載地址：http://dev.mysql.com/downloads/mysql/

• 選擇符合你的操作系統的版本，點擊download進入下載頁面

• 不用注冊也可以點擊下載連接進行下載

2、安裝

• 解壓下載的壓縮文件到你的mysql安裝目錄（目錄能不能有中文沒測試過，你可以試一下），以下是我的解壓目錄

　

• 復制解壓目錄D:\javaEnvironment\mysql-5.7.12-winx64下的my-default.ini命名為my.ini，打開my.ini添加如下配置、保存：

# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

# Remove leading # to turn on a very important data integrity option: logging

• 設置環境變量，在環境變量path變量中后面添加上上面的mysql解壓目錄的bin路勁D:\javaEnvironment\mysql-5.7.12-winx64\bin，注意添加前加上‘;’號
• win+r,輸入cmd進入windows Dos界面
• 進入解壓的/bin目錄下，（重要）執行命令mysqld --initialize，5.7之后需要初始化生成數據庫文件（根目錄下的data文件），否則后續無法啟動服務
• 執行命令mysqld -install，安裝mysql服務
• 執行命令net start mysql，啟動服務

• 執行命令mysql -uroot -p，會報錯ERROR 1045(28000)，需要設置登錄密碼
• 打開配置文件my.ini，將skip-grant-tables前面的#去掉，然后重啟服務，再次登錄就可略過密碼

• 進入mysql數據庫，依次執行以下命令：

  use mysql;

  update user set authentication_string=password("root") where user="root";     //注意：這里"root"修改為你的密碼，如："123456"

  flush privileges;

  quit;

• 打開配置文件my.ini，在skip-grant-tables前面加上#注釋掉，然后重啟服務，使用設置的密碼再次登錄

• mysql登陸后執行：SET PASSWORD = PASSWORD('123456');    原因參考官網說明：http://dev.mysql.com/doc/refman/5.6/en/alter-user.html。（ps:英文不好，沒看懂，看懂的可以給我指點一下）
• 然后就可以在版本的mysql客戶端SQLyog中連接mysql server了,但是這時候別的機器還不能訪問本機的mysql server，如下三步操作解決問題:

1. use mysql;  //進入mysql數據庫
2. update user set host = '%' where user = 'root';    //可能是你的帳號不允許從遠程登陸，只能在localhost。這個時候只要在localhost的那台電腦，登入mysql后，更改 "mysql" 數據庫里的 "user" 表里的 "host" 項，從"localhost"改稱"%"
3. GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'  WITH GRANT OPTION; //賦予任何主機訪問數據的權限
4. FLUSH PRIVILEGES //修改生效
