mysql 简单的管理命令:
启动mysql sudo start mysql
停止mysql sudo stop mysql
允许远程访问的设置:
<code class="hljs bash">sudo vi /etc/mysql/my.cnf 注释掉 bind-address = 127.0.0.1</code>
增加新用户:
<code class="hljs bash"><code class="hljs sql">GRANT ALL PRIVILEGES ON *.* TO gino@'%' IDENTIFIED BY "123456"; </code></code>
<code class="hljs bash"><code class="hljs sql"><code class="hljs sql">GRANT命令说明: ALL PRIVILEGES 是表示所有权限,你也可以使用select、update等权限。 ON 用来指定权限针对哪些库和表。 *.* 中前面的*号用来指定数据库名,后面的*号用来指定表名。 TO 表示将权限赋予某个用户。 jack@'localhost' 表示jack用户,@后面接限制的主机,可以是IP、IP段、域名以及%,%表示任何地方。注意:这里%有的版本不包括本地,以前碰到过给某个用户设置了%允许任何地方登录,但是在本地登录不了,这个和版本有关系,遇到这个问题再加一个localhost的用户就可以了。 IDENTIFIED BY 指定用户的登录密码。 WITH GRANT OPTION 这个选项表示该用户可以将自己拥有的权限授权给别人。注意:经常有人在创建操作用户的时候不指定WITH GRANT OPTION选项导致后来该用户不能使用GRANT命令创建用户或者给其它用户授权。 备注:可以使用GRANT重复给用户添加权限,权限叠加,比如你先给用户添加一个select权限,然后又给用户添加一个insert权限,那么该用户就同时拥有了select和insert权限。</code></code></code>
<code class="hljs bash"><code class="hljs sql"><code class="hljs sql"><code class="hljs sql">使用这个命令使权限生效,尤其是你对那些权限表user、db、host等做了update或者delete更新的时候。以前遇到过使用grant后权限没有更新的情况,只要对权限做了更改就使用FLUSH PRIVILEGES命令来刷新权限。 flush privileges;</code></code></code></code>

The root user is a user with unrestricted system administrative rights. He has permissions to access and modify files, user management, software installation and removal, and system configuration changes.

The root user can execute important system commands and edit system files, which ordinary users cannot do. In this guide, I'll explore the Ubuntu root user, how to log in as root, and how it differs from a normal user. Notice

sudo (superuser execution) is a key command in Linux and Unix systems that allows ordinary users to run specific commands with root privileges. The function of sudo is mainly reflected in the following aspects: Providing permission control: sudo achieves strict control over system resources and sensitive operations by authorizing users to temporarily obtain superuser permissions. Ordinary users can only obtain temporary privileges through sudo when needed, and do not need to log in as superuser all the time. Improved security: By using sudo, you can avoid using the root account during routine operations. Using the root account for all operations may lead to unexpected system damage, as any mistaken or careless operation will have full permissions. and
