CentOS：在 PHP 安装中启用 GD 支持

Question

我如何在 CentOS 安装中启用 GD 支持？

Answer 1

The thing that did the trick for me eventually was:

yum install gd gd-devel php-gd

and then restart apache:

service httpd restart

Answer 2

1. You need to find a repo that offers a GD lib matching your current php version. I've had great success using Remi Collet's repo for this purpose. In fact, I used it yesterday to update my php install to the latest 5.4.0RC6 version on my CentOS6 box.
2. Once you've setup the repo it's a simple matter of running sudo yum install php-gd
3. Of course, the usual things apply: make sure you restart apache after installing, etc.

Answer 3

With CentOS 6.5+ and PHP 5.5:

yum install php55u-gd
service httpd restart

If you get an error like: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0 , it could be because you don't have a swap file. I suggest you take a look at the tutorial mentioned in this answer: https://stackoverflow.com/a/20275282/828366
