一、安装MySQL

  1. 执行如下命令apt install mysql-server 之后会有个提示输入:y。如下
  1. 安装完成之后输入以下命令查看是否成功netstat -tap | grep mysql 显示LISTEN则代表安装成功

二、配置MySQL

  1. 此时可以输入以下命令直接进入mysql,没有密码 mysql -u root -p 输入密码出直接回车,可以查看所有数据库
  1. 接下来退出mysql,执行以下命令对mysql进行配置 mysql_secure_installation 接着的具体选择说明如下: Securing the MySQL server deployment. Connecting to MySQL using a blank password. VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin? == # 要安装验证密码插件吗?== Press y|Y for Yes, any other key for No: N # 这里我选择N Please set the password for root here. New password: # 输入要为root管理员设置的数据库密码 Re-enter new password: # 再次输入密码 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. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : y # 删除匿名账户 Success. 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) : N # 禁止root管理员从远程登录,这里我没有禁止 … skipping. By default, MySQL comes with a database named ‘test’ that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y # 删除test数据库并取消对它的访问权限
    • Dropping test database… Success.
    • Removing privileges on test database… Success.

    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 == # 刷新授权表,让初始化后的设定立即生效== Success. All done!

  2. 检查MySQL服务状态 systemctl status mysql 显示如下则代表正常
  1. 再次登录进入MySQL,使用刚设置的密码
  1. 配置MySQL允许远程访问,编辑以下文件 vim /etc/mysql/mysql.conf.d/mysqld.cnf 注释掉bind-address = 127.0.0.1

然后保存退出

三、进入MySQL数据,执行授权命令

代码语言:javascript
复制
mysql -u root -p

mysql> grant all on *.* to root@'%' identified by '你的密码' with grant option;

mysql> flush privileges;    # 刷新权限

mysql> exit

如下:

重启mysql:

代码语言:javascript
复制
systemctl restart mysql

四、使用Navicat for MySQL连接
