重裝系統之后準備安裝mysql,看到官網上有mysql 5.7.10可以下載就點了,然后就開始了漫長的安裝路程,總共折騰差不多一個多小時,最后終于安裝成功了,這里把安裝過程寫下來,給自己做個筆記,也給后來人一個安裝提示.

1.下載安裝包

直接點擊或者復制之后就可以下載了,不嫌麻煩或者想體驗其他版本的也可以去官網下載,但是請注意,筆記只在5.7.10這個版本下運行成功,其他版本(僅供參考)需要參考官方的安裝文檔!

2.解壓縮文件夾到本地磁盤

我把文件放在了

C:\Program_Files\mysql-5.7.10-winx64

3.復制my-default.ini為my.ini

建議復制一份,或者直接把my-default.ini重命名為my.ini

4.填寫my.ini相關內容

basedir=C:\Program_Files\mysql-5.7.10-winx64

datadir=C:\Program_Files\mysql-5.7.10-winx64\data

port=3306

路徑請替換成自己實際路徑!

5.環境變量

新增環境變量,如下圖

修改path,注意是修改,增加的是后面我選中的部分

%MYSQL_HOME%\bin;

6.管理員權限運行[命令提示符]

盡量使用管理員權限運行,否則,可能出現無法安裝或者無法啟動服務等問題!

7.執行mysql初始化data

mysqld --initialize --console

結果如下:

C:\Windows\system32>mysqld --initialize --console2015-12-25T03:01:33.140732Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation formore details).2015-12-25T03:01:33.140732Z 0 [Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode ina future release.2015-12-25T03:01:33.140732Z 0 [Warning] 'NO_AUTO_CREATE_USER' sql mode was not set.2015-12-25T03:01:34.614085Z 0 [Warning] InnoDB: New log files created, LSN=45790

Table 'mysql.gtid_executed'cannot be opened.2015-12-25T03:01:34.891376Z 1 [Note] A temporary password is generated for root@localhost: +>><=Gs,0spF

請注意,最后一句包含我們所需要的初始化密碼!!!!

8.安裝mysql服務,并啟動

C:\Windows\system32>mysqld -install

Service successfully installed.

C:\Windows\system32>net start mysql

MySQL 服務正在啟動 .

MySQL 服務已經啟動成功。

9.登錄mysql并修改密碼

請注意,我下面的密碼和上面的那個初始化密碼不一樣了,因為我有重新卸載了服務然后重新執行了一遍 7和8 ,因為上面的密碼提示我無法登錄,"

C:\Windows\system32>mysql -uroot -pih.sQWazK9*7

mysql> set password for 'root'@'localhost'="你的密碼";

Query OK,0 rows affected (0.00 sec)

好了,現在退出

mysql>exit

Bye

10.修改遠程登錄

到上面9 的時候本機已經可以正常使用mysql的功能了,不過如果需要遠程登錄mysql的話需要下面的設置

C:\Windows\system32>mysql -uroot -p你的密碼

mysql: [Warning] Using a password on the command lineinterfacecan be insecure.

好了,到這里全部完成了,開始你的mysql之旅吧!
