手动安装 php 扩展（从一台服务器复制到另一台服务器）

Question

I am trying to use the following imagick code in my backup server:

<?php

header('Content-type: image/jpeg');

$image = new Imagick('image.jpg');

$image->thumbnailImage(100, 0);

echo $image;

?>

However, this is a backup server which is not having the imagick.so installed. Our office has one primary server (same OS version, same linux distribution) with the imagick.so. Can I manually copy the imagickso to the backup server and make it working?

Answer 1

Normally you should build the PHP extension in your server thru package management (yum install, or apt-get). But if it is not possible then you may try the steps below.

If you have the so file (in your case imagick.so) which is fully functional (and virus free) in a server of EXACTLY the same linux distribution and version. You may try to copy the file to your target server path:

/usr/lib64/php/modules/imagick.so

or, if the server is 32 bit

/usr/lib32/php/modules/imagick.so

then open your php.ini (mostly it is /etc/php.ini) and at the end of the file add the following:

extension=imagick.so

After that, restart your apache and it should be ok. However, please make sure you can access this server for further troubleshooting because in case of any problem you can revert the changes you have made.
