  • mysql8.0 windows10 源码安装

    1)mysql官网下载源码 https://dev.mysql.com/downloads/mysql/

    2)安装与配置文件

    在解压后的mysql包中新建 my.ini文件

     my.ini文件中需要添加的内容如下:

    [client]
    port=3306
    default-character-set=utf8
     
    [mysql]
    default-character-set=utf8
     
    [mysqld]
    #端口
    port=3306
    # 软件路径
    basedir="F:/Program Files/mysql-8.0.15-winx64"
    # 数据保存位置
    datadir="F:/Program Files/mysql-8.0.15-winx64/Data"
    # 允许最大连接数
    max_connections=5
    # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
    max_connect_errors=3
    # 服务端使用的字符集默认为UTF8
    character-set-server=utf8
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB
    # 默认使用“mysql_native_password”插件认证
    default_authentication_plugin=mysql_native_password

    3)数据库初始化

    以管理员身份运行命令提示符,进入MySQL安装目录的 bin 目录下执行命令:mysqld --initialize --console,不知道怎么进入bin目录,可以去百度,这里就不详细说明

    F:Program Filesmysql-8.0.15-winx64in>mysqld --initialize --console
    [Server] C:Program FilesMySQLinmysqld.exe (mysqld 8.0.11) initializing of server in progress as process 4984
    [Server] A temporary password is generated for root@localhost: fQaP#D1RFMeF

    4)安装和启动数据库服务

    PS F:Program Filesmysql-8.0.15-winx64in> mysqld --install
    Service successfully installed.
    PS F:Program Filesmysql-8.0.15-winx64in> net start mysql
    MySQL 服务正在启动 ..
    MySQL 服务已经启动成功。

    5)登陆和更换密码

    在MySQL安装目录的 bin 目录下执行命令:mysql -u root -p,然后输入初始化时的到密码,进入成功之后,在MySQL中执行命令:ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码';,如下图所示,成功修改密码

    PS F:Program Filesmysql-8.0.15-winx64in> mysql -uroot -p
    Enter password: ************
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 8
    Server version: 8.0.15

    Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.
     
    mysql> use mysql;
    ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
    mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'test123';
    Query OK, 0 rows affected (0.08 sec)
     
    mysql>

    可以用 命令查看一下默认安装的数据库:show databases

    mysql> show databases
        -> ;
    +--------------------+
    | Database           |
    +--------------------+
    | information_schema |
    | mysql              |
    | performance_schema |
    | sys                |
    +--------------------+
    4 rows in set (0.00 sec)
