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!
2.解压缩文件夹到本地磁盘
我把文件放在了
C:Program_Filesmysql-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_Filesmysql-5.7.10-winx64 datadir=C:Program_Filesmysql-5.7.10-winx64data 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%in;
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:Windowssystem32>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. 2015-12-25T03:01:33.140732Z 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 2015-12-25T03:01:34.775606Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2015-12-25T03:01:34.872089Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: ceb98c90-aab3-11e5-8ca7-b870f4733564. 2015-12-25T03:01:34.872089Z 0 [Warning] Gtid table is not ready to be used. 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
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:Windowssystem32>mysqld -install Service successfully installed. C:Windowssystem32>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:Windowssystem32>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:Windowssystem32>mysql -uroot -p你的密码 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or g.

好了,到这里全部完成了,开始你的mysql之旅吧!
