    作者:天意天雨 栏目:未分类 时间:2020-06-30 10:05:10

    1、解压压缩包

    我的放到:K:\Mysql5.7\mysql-5.7.15-winx64

     

    2、配置环境变量

    新建MYSQL_HOME:
    K:\Mysql5.7\mysql-5.7.15-winx64
    path 添加 :
    %MYSQL_HOME%\bin

     

    3、新建并修改配置文件my.ini

    [mysql]
    # 设置mysql客户端默认字符集
    default-character-set=utf8
    [mysqld]
    #设置3306端口
    port = 3306
    # 设置mysql的安装目录
    basedir=K:\Mysql5.7\mysql-5.7.15-winx64
    # 设置mysql数据库的数据的存放目录 
    datadir
    =K:\Mysql5.7\mysql-5.7.15-winx64\data

    # 允许最大连接数
    max_connections=200 
    # 服务端使用的字符集默认为8比特编码的latin1字符集
    character
    -set-server=utf8
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB

     

    4、初始化数据库

    以管理员的方式打开命令行:
    PS C:\Windows\system32> mysqld --initialize --user=mysql --console 2020-06-30T01:31:27.290738Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2020-06-30T01:31:28.141309Z 0 [Warning] InnoDB: New log files created, LSN=45790 2020-06-30T01:31:28.227364Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2020-06-30T01:31:28.306351Z 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: 6b55a09e-ba71-11ea-b270-b025aa16da03. 2020-06-30T01:31:28.313346Z 0 [Warning] Gtid table is not ready to be used.

    5、安装服务

    去到mysql解压目录:

    PS D:\> K:
    PS K:\> cd .\Mysql5.7\mysql-5.7.15-winx64\bin\
    PS K:\Mysql5.7\mysql-5.7.15-winx64\bin>
    安装服务
    PS K:\Mysql5.7\mysql-5.7.15-winx64\bin> mysqld --install Service successfully installed.

     

    6、修改密码

    启动服务
    net start mysql

    PS K:\Mysql5.7\mysql-5.7.15-winx64\bin> net start mysql
    MySQL 服务正在启动 .
    MySQL 服务已经启动成功。

    PS K:\Mysql5.7\mysql-5.7.15-winx64\bin> mysql -u root -p+NtbdOBdG8fV
    mysql: [Warning] Using a password on the command line interface can be insecure.

    mysql>


    使用初始密码登陆后(上面的初始密码),执行指令 set password for root@localhost=password('你的需要修改的密码');
    mysql> set password for root@localhost=password('mysql');
    Query OK, 0 rows affected, 1 warning (0.00 sec)
    若找不到初始密码可以在my.ini中[mysqld] 添加
    skip-grant-tables
