Mysql-winx64 安装教程

3.配置my.ini文件

在解压根目录新建一个my.ini的文件

1.  
   # For advice on how to change settings please see
2.  
   # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
3.  
   # *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the
4.  
   # *** default location during install, and will be replaced if you
5.  
   # *** upgrade to a newer version of MySQL.
6.  
    
7.  
   [mysqld]
8.  
    
9.  
   # Remove leading # and set to the amount of RAM for the most important data
10.  
    # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
11.  
    # innodb_buffer_pool_size = 128M
12.  
     
13.  
    # Remove leading # to turn on a very important data integrity option: logging
14.  
    # changes to the binary log between backups.
15.  
    # log_bin
16.  
     
17.  
    # These are commonly set, remove the # and set as required.
18.  
    basedir = "D:\\Program Files\mysql-5.7.21-winx64"
19.  
    datadir = "D:\\Program Files\mysql-5.7.21-winx64\data"
20.  
    port = 3306
21.  
    character_set_server = utf8
22.  
     
23.  
    # server_id = .....
24.  
     
25.  
     
26.  
    # Remove leading # to set options mainly useful for reporting servers.
27.  
    # The server defaults are faster for transactions and fast SELECTs.
28.  
    # Adjust sizes as needed, experiment to find the optimal values.
29.  
    # join_buffer_size = 128M
30.  
    # sort_buffer_size = 2M
31.  
    # read_rnd_buffer_size = 2M
32.  
     
33.  
    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

4.管理员方式启动命令提示窗符

进入mysql解压目录到bin目录下

如：D:\Program Files\mysql-5.7.21-winx64\bin

分别执行：

（1）初始化：mysqld -initialize-insecure

如果报错failed to set datadir to 则 执行一下  mysqld --initialize --user=mysql --console，再执行（1）；

正确之后会在Mysql解压根目录生成data文件夹以及相关文件

（2）mysqld -install

*如提示Install/Remove of the Service Denied，说明不是已管理员的方式进入的命令提示符

（3）启动服务：net start mysql

（4）登陆，改密码 mysql -u root -p 

【成功登陆的直接到（5）】

我的出现了

在my.ini中增加

重启服务，成功登陆

（5）执行改密码语句 （正常登陆的使用set password= password(‘新密码’);）

update user set authentication_string = password("新密码") where user=‘root‘;

（6）exit;  net stop mysql

(7)登陆成功的忽略这一步

到my.ini中注释掉

重启进入之后set password= password(‘新密码’);

到此就可以正常使用了。

（8）测试 show databases;

5.写两个bat文件用于启动和关闭mysql服务

（1）启动mysql服务

1.  
   @echo off
2.  
   echo 确定要启动MySQL服务吗？
3.  
   pause
4.  
   net start mysql
5.  
   echo 启动MySQL服务完成，请确认有没有错误发生。
6.  
   Pause
