以下的文章主要介绍的是ubuntu 彻底删除MySQL数据库,以及删除MySQL数据库之后对MySQL的重装与删除MySQL的实际操作步骤,如果你对其实际操作感兴趣的话,你就可以浏览以下的文章了。
<ol class="dp-xml"> <li class="alt"><span>sudo apt-get autoremove --purge MySQL-server-5.0 </span></li> <li> <span>sudo apt-get remove </span>MySQL<span>-server </span> </li> <li class="alt"> <span>sudo apt-get autoremove </span>MySQL<span>-server </span> </li> <li> <span>sudo apt-get remove </span>MySQL<span>-common </span> </li> </ol>
这个很重要上面的其实有一些是多余的。
清理残留数据
<ol class="dp-xml"><li class="alt"><span><span>dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P </span></span></li></ol>
安装 MySQL数据库
<ol class="dp-xml"><li class="alt"> <span>sudo apt-get install MySQL-serversudo apt-get install </span>MySQL<span>-clientsudo apt-get install php5-</span>MySQL<span> </span> </li></ol>
安装php5-MySQL数据库 是将php和MySQL连接起来一旦安装完成,MySQL 服务器应该自动启动。您可以在终端提示符后运行以下命令来检查 MySQL 服务器是否正在运行:sudo netstat -tap | grep MySQL
当您运行该命令时,您可以看到类似下面的行:
<ol class="dp-xml"><li class="alt"><span>tcp 0 0 localhost.localdomain:MySQL *:* LISTEN - </span></li></ol>
如果服务器不能正常运行,您可以通过下列命令启动它:
<ol class="dp-xml"><li class="alt"><span>sudo /etc/init.d/MySQL restart </span></li></ol>
进入MySQL
$MySQL -uroot -p 管理员密码
配置 MySQL数据库 的管理员密码:
<ol class="dp-xml"><li class="alt"><span>sudo MySQLadmin -u root password newpassword </span></li></ol>
以上的相关内容就是对ubuntu 彻底删除 MySQL数据库 然后重装 MySQL删除 MySQL的介绍,望你能有所收获。

Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.
