  • ubuntu 18.04 安装 MySql,并配置远程连接

    1.安装MySQL

    在Ubuntu中,默认情况下,只有最新版本的MySQL包含在APT软件包存储库中,要安装它,只需更新服务器上的包索引并安装默认包apt

    #命令1
    sudo apt-get update
    #命令2
    sudo apt-get install mysql-server

    2.配置MySQL

    2.1 初始化配置

    sudo mysql_secure_installation

    配置选项如下:

    #1
    VALIDATE PASSWORD PLUGIN can be used to test passwords...
    Press y|Y for Yes, any other key for No: N (我的选项)
    
    #2
    Please set the password for root here...
    New password: (输入密码)
    Re-enter new password: (重复输入)
    
    #3
    By default, a MySQL installation has an anonymous user,
    allowing anyone to log into MySQL without having to have
    a user account created for them...
    Remove anonymous users? (Press y|Y for Yes, any other key for No) : N (我的选项)
    
    #4
    Normally, root should only be allowed to connect from
    'localhost'. This ensures that someone cannot guess at
    the root password from the network...
    Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y (我的选项)
    
    #5
    By default, MySQL comes with a database named 'test' that
    anyone can access...
    Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N (我的选项)
    
    #6
    Reloading the privilege tables will ensure that all changes
    made so far will take effect immediately.
    Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y (我的选项)

    2.2 检查mysql服务状态

    systemctl status mysql.service

    3.配置远程访问

    在Ubuntu下MySQL缺省是只允许本地访问的,使用workbench连接工具是连不上的;
    如果你要其他机器也能够访问的话,需要进行配置;

    sudo mysql -uroot -p

    输入密码;然后输入命令:

    GRANT ALL PRIVILEGES ON *.* TO 'root'@"%" IDENTIFIED BY "123456"; 

    root为账户,123456为账户密码。

    然后更新 PRIVILEGES

    FLUSH PRIVILEGES;

    重启mysql:

    sudo systemctl restart mysql.service
    #或者
    sudo
    /etc/init.d/mysql restart

    #开启mysql命令
    sudo systemctl start mysql.service

    #关闭mysql命令
    sudo systemctl stop mysql.service

    修改配置文件,把127.0.0.0 的那一行前面加个#号,:wq保存

    sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf #打开这个文件

    该努力的时候努力 该休息的时候休息
