Windows下压缩包安装Mysql

1. 下载mysql压缩包

2. 解压到指定目录，例如D:Program Filesmysql-5.7.25-winx64

3. 在目录下创建配置文件my.ini

[mysqld]
port = 3306
basedir=D:/Program Files/mysql-5.7.25-winx64
datadir=D:/Program Files/mysql-5.7.25-winx64/data 
max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[mysql]
default-character-set=utf8

4. 安装命令

D:Program Filesmysql-5.7.25-winx64in>mysqld -install

Service successfully installed.//安装成功

5. 初始化命令

D:Program Filesmysql-5.7.25-winx64in>mysqld --initialize-insecure --user=mysql

成功没有提示，失败有相应提示。

6. 启动命令

D:Program Filesmysql-5.7.25-winx64in>net start mysql

MySQL 服务正在启动 .

MySQL 服务已经启动成功。

7. 修改密码

D:Program Filesmysql-5.7.25-winx64in>mysqladmin -u root -p password 123456 //123456就是设置的密码
Enter password: //由于默认没有密码，直接回车即可

8. 一个典型的问题

在执行步骤4的时候，提示已经安装

D:Program Filesmysql-5.7.25-winx64in>mysqld -install

The service already exists!
The current server installed: "D:Program Filesmysql-5.7.23-winx64inmysqld" MySQL

此时需要执行以下命令：

8.1 确认Mysql服务是否已经注册

D:Program Filesmysql-5.7.25-winx64in>sc query mysql

SERVICE_NAME: mysql
TYPE : 10 WIN32_OWN_PROCESS
STATE : 1 STOPPED
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x7d0

8.2 删除注册服务

D:Program Filesmysql-5.7.25-winx64in>sc delete mysql

[SC] DeleteService 成功

可以重新安装了mysqld -install
