- 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 repofor this purpose. In fact, I used it yesterday to update my php install to the latest 5.4.0RC6 version on my CentOS6 box.
- Once you've setup the repo it's a simple matter of running
sudo yum install php-gd - Of course, the usual things apply: make sure you restart apache after installing, etc.
- 您需要找到一个提供与您当前 php 版本匹配的 GD 库的存储库。为此，我使用Remi Collet 的 repo取得了巨大的成功。事实上，我昨天使用它在我的 CentOS6 机器上将我的 php 安装更新到最新的 5.4.0RC6 版本。
- 一旦你设置了 repo，它就是一个简单的运行问题
sudo yum install php-gd - 当然，通常的事情适用：确保在安装后重新启动apache等。

With CentOS 6.5+ and PHP 5.5:
使用 CentOS 6.5+ 和 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
