重装系统之后准备安装mysql,看到官网上有mysql 5.7.10可以下载就点了,然后就开始了漫长的安装路程,总共折腾差不多一个多小时,最后终于安装成功了,这里把安装过程写下来,给自己做个笔记,也给后来人一个安装提示.

　　1.下载安装包

　　直接点击或者复制之后就可以下载了,不嫌麻烦或者想体验其他版本的也可以去官网下载,但是请注意,笔记只在5.7.10这个版本下运行成功,其他版本(仅供参考)需要参考官方的安装文档!

　　http://120.192.95.132/cache/dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.10-winx64.zip?ich_args=33a24030fa5191a36f50adaf2a0329c5_1_0_0_5_9c71accd314cb3f9f9f6e66f07ef13e42dd4f7c2bf4ea27f34b88c04e33f0945_80de45f03e1c6ffbe40617244bdec41b_1_0&ich_ip=

　　2.解压缩文件夹到本地磁盘

　　我把文件放在了

C:\Program_Files\mysql-5.7.10-winx64

　　3.复制my-default.ini为my.ini

建议复制一份,或者直接把my-default.ini重命名为my.ini

　　4.填写my.ini相关内容

basedir=C:\Program_Files\mysql-5.7.10-winx64
datadir=C:\Program_Files\mysql-5.7.10-winx64\data
port=3306

路径请替换成自己实际路径!

　　5.环境变量

新增环境变量,如下图

修改path,注意是修改,增加的是后面我选中的部分

%MYSQL_HOME%\bin;

　　6.管理员权限运行[命令提示符]

尽量使用管理员权限运行,否则,可能出现无法安装或者无法启动服务等问题!

　　7.执行mysql初始化data

mysqld --initialize --console

结果如下:

C:\Windows\system32>mysqld --initialize --console
2015-12-25T03:01:33.140732Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more 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 in a future release.

2015-12-25T03:01:34.891376Z 1 [Note] A temporary password is generated for [email protected]: +>><=Gs,0spF

请注意,最后一句包含我们所需要的初始化密码!!!!

　　8.安装mysql服务,并启动

C:\Windows\system32>mysqld -install
Service successfully installed.

C:\Windows\system32>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

　　9.登录mysql并修改密码

请注意,我下面的密码和上面的那个初始化密码不一样了,因为我有重新卸载了服务然后重新执行了一遍 7和8 ,因为上面的密码提示我无法登录,"<"无法识别!!!不知道有没有人知道是为什么?难道随机的密码太随机了?

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

mysql>  set password for ‘root‘@‘localhost‘="你的密码";
Query OK, 0 rows affected (0.00 sec)

好了,现在退出

mysql> exit
Bye

　　10.修改远程登录

到上面9 的时候本机已经可以正常使用mysql的功能了,不过如果需要远程登录mysql的话需要下面的设置

C:\Windows\system32>mysql -uroot -p你的密码
mysql: [Warning] Using a password on the command line interface can be insecure.
