我正在尝试mysql，但收到以下错误：

sudo /etc/init.d/apache2 start
 * Starting web server apache2                                                                                                                                                                               * 
ubuntu@ip-172-31-19-47:/var/www/html/anunciolocal$ sudo /etc/init.d/mysql start
 * /etc/init.d/mysql: ERROR: The partition with /var/lib/mysql is too full!

当我检查我的记忆时：

ubuntu@ip-172-31-19-47:~$ df -h

怎么解决？
