我一直试图在我的Ubuntu 12.04服务器上安装Gitlab很长一段时间,一切顺利,直到我运行bundle install.

它说它无法安装MySQL2,但没有给出任何理由或纠正措施.

我试图读取存储在S3中的700MB文件.我怎么只需要从位置73到1024的字节.

我试图找到一个可用的解决方案,但未能成功.如果有人可以帮助我,那将是一个很大的帮助.

我正在编写一个简单的代码来从我的数据库中名为Plasma的表中获取2个元素.似乎连接正常,但由于未知原因我无法选择任何数据库.

代码:

<?php
$db  = "Plasma"; 
$dbH = "localhost";
$dbU = "plasma";
$dbP = "plasma";
      $dbCon = mysqli_connect($dbH,$dbU,$dbP,$db);
        if(!dbCon){
            echo "Conenction Fail";
        }
        mysqli_select_db($dbCon,$db);
        $qry = "select Mid,Mname from ya_movies order by DOA limit 5;";
        $Response = mysqli_query($dbCon,$qry);
        echo mysqli_error($dbCon);                     ?>

输出是
