centos5 gforge 5.6 简易安装过程

首先到gforge官方下载安装源码。链接为http://gforgegroup.com/es/download.php。下载得install-gforge-as-561-src.zip安装包，这是高级版，另外有install-gforge-ce-561-src.zip社区版。安装方法差不多。

解压

# unzip install-gforge-as-561-src.zip

# cd gforge-as-561-src

# more INSTALL 查看安装说明。

# yum install php

-=# Welcome to GForge Pre-Installer v5.0 #=-

Done.
GForge5 has been successfully installed and configured.

然后查看README.PERFORMANCE文件
#cat README.PERFORMANCE

==============================================
The ioncube-encoded version of GForge AS can be sped up significantly
by pre-loading the ioncube loaders. This can increase performance by
up to 50-75% and is noticeable on slower or busy servers. To do this,
go to the ioncube directory in gforge5 like this:

cd /opt/gforge5/ioncube

And run the loader-helper script.

php ioncube-loader-helper.php

Type 1 to get the instructions for the line that you need to be placed
into your php.ini. Place the line as directed and restart apache.

/etc/init.d/httpd restart

Usually, adding a line like this to your php.ini will be correct, but
verify using the script above:

zend_extension = /opt/gforge5/ioncube/ioncube_loader_lin_5.1.so

OTHER NOTES
-----------

Q: GForge AS Seems slow, what can I do?

A: GForge AS is written almost entirely in object-oriented code and
requires a fairly decent CPU to rip through it quickly and generate
pages.

1) If you are on a vmware server, make sure the CPU of the base
server is not saturated. If there are too many interrupts and/or
the CPU is saturated, it will take longer to serve up the complex
pages for GForge.

2) Use the installer to install gforge on a real machine and be
sure to follow the README.PERFORMANCE document in the doc root. Any
reasonably modern server should easily handle GForge when it's
installed directly on the server instead of in a vmware image.

3) Make sure enough memory is allocated to your system. If you're
running vmware, make sure the guaranteed memory is at least 768MB
or some swapping can occur and that will really kill performance.

4) If you're running an older vmware server product, the
downloadable vmware image may not perform well in compatibility
mode. You'll probably want to create a new vm on your server with
centos5 and use the GForge installer.
===============================================

根据以上信息：

# cd /opt/gforge5/ioncube

# php ioncube-loader-helper.php

提示后选1 ，看到如下信息

==================
ionCube Loader Install Assistant
--------------------------------

Analysis of your system configuration shows:

To install the Loader in your php.ini file, edit or create the file

/etc/php.ini

and add the following line before any other zend_extension lines:

zend_extension = //ioncube_loader_lin_5.1.so

where // is where you've installed the loader, e.g. /usr/local/ioncube/

If there are no zend_extension lines already, you can put the
line at any point in the file.

Finally, stop and restart your web server software for the changes to
take effect.

Installing the Loader for run-time loading
------------------------------------------

To install for runtime loading, create a directory called ioncube
at or above the top level of your encoded files, and ensure that the directory
contains the ioncube_loader_lin_5.1.so loader. If run-time install of
the Loader is possible on your system then encoded files should automatically
install the loader when needed.
=======================================
由红色部分内容可知 php.ini 需要添加：

# vim /etc/php.ini

如果存在zend_extension ='……'，在前面添加 zend_extension = /opt/gforge5/ioncube/ioncube_loader_lin_5.1.so，否则在最后添加此句。

保存退出。

重启apache:

# /etc/init.d/httpd restart
