获得空白的PHP页面上的Apache [英] Getting blank PHP page over Apache

问题描述

在新设置的digitalOcean云服务器（CentOS的），我已经安装了PHP和Apache。 Web服务器正在运行的罚款：

In a newly setup digitalOcean cloud server (CentOS), I have installed php and Apache. The webserver is running fine:

[root@a2m5cent01 httpd]# service httpd status
httpd (pid  11232) is running...
[root@a2m5cent01 httpd]# php --version | head -1
PHP 5.3.3 (cli) (built: Dec 11 2013 03:29:57) 

不过，浏览器显示，如果我尝试访问任何PHP页面空白页（白页）。

But browser is showing blank pages (white page) if I try to visit any php page.

这是我迄今所做的解决：

Here is what I have done so far to troubleshoot:

1. 创建一个页面，内容如下：<？code>＆LT; PHP的phpinfo（）; ？＆GT; 。它显示从浏览器中查看时，一个空白页。


2. 只是为了确保，Apache是​​指向正确的目录中，放置一个静态的.html 页那里，看到它有浏览器了罚款，所以Apache是​​工作，目录是正确的。


3. 在 /etc/php.ini中，修改的display_errors 指令在。还是空白页


4. 在Apache的配置文件（ /etc/httpd/conf/httpd.conf中）发现，这一行包括conf.d / *。CONF 。在 conf.d 目录中，有包含行 php.conf 文件：
   的LoadModule php5_module模块/ libphp5.so 。确保这个.so文件在这个地方确实存在。


5. 在同一个文件中我有这两条线，以及： AddHandler的PHP5脚本的.php 和将AddType text / html的.PHP


6. 执行的从CLI PHP页面，它工作正常 - 所以PHP是在本地工作

1. Created a page with following content: <?php phpinfo(); ?>. It displays a blank page when viewed from browser.
2. Just to ensure, apache is pointing to the correct directory, placed a static .html page there, and saw it comes out fine in browser, so apache is working and directory is correct.
3. In /etc/php.ini, changed display_errors directive to On. Still blank page
4. In Apache config file (/etc/httpd/conf/httpd.conf) found this line Include conf.d/*.conf. Inside conf.d directory, there is a php.conf file containing the line: LoadModule php5_module modules/libphp5.so. Ensured that this .so file actually exists in this place.
5. In the same file I have these two lines as well: AddHandler php5-script .php and AddType text/html .php
6. Executed the php page from CLI, it works fine - so php is working locally.

那么为什么它总是显示一个空白/白页在浏览器？还有什么我缺少什么？

Then why is it always shows a blank/white page over the browser? What else am I missing?

根据建议，由@Nathan，

EDIT Based on suggestions from @Nathan,

1. 我检查Apache的错误日志文件，看不出任何错误是
   有报道


2. 我的 /etc/php.ini中说，PHP error_log中的位置如日志。所以，我检查的/ var / log / messages中，但找不到任何PHP错误信息


3. 接下来，我把一些正常的 HTML 包含的phpinfo（）调用PHP文件。有趣的是，我发现，即使是正常的HTML文本也不会来。它的还是的生产空白页。


4. 然后我检查的Apache 访问日志。惊喜！没有任何PHP文件我试图在浏览器中加载的任何 GET 请求。但是获取所有的非PHP 请求文件有200回报code。

1. I checked Apache error log file, could not see any error being reported there.
2. My /etc/php.ini says, php error_log is located as syslog. So I checked /var/log/messages but could not find any PHP error message
3. Next I put some normal HTML in the php file containing phpinfo() call. Interestingly I found that even the normal HTML texts are also not coming. It still produces blank page.
4. Then I checked Apache access log. Surprise! There is no GET request for any of the PHP files I tried to load in the browser. But GET request for all the non-php files are there with 200 return code.

Apache是​​的不可以即使日志记录PHP文件的访问请求。任何想法，为什么会发生呢？

Apache is not even logging any access request for PHP files. Any idea why would that happen?

推荐答案

我觉得你的PHP的安装与Apache故障。这就是为什么你不能看到任何PHP页面在你的网络服务器。清洁删除所有现有的应用程序，像httpd，PHP，PHP-FPM，PHP-CLI等，并尝试清洁6.在安装按照此顺序

I think your php installation with apache is faulty. Thats why you can not see any php page in your webserver. Clean remove all the existing apps, like httpd,php,php-fpm,php-cli etc. and try to clean isntall in this order

yum install httpd -y
yum install php php-common php-cli php-gd php-curl php-fpm -y

然后确保你重新启动httpd的YOUT服务器。

then make sure you restart yout httpd server.

service httpd restart

安装的mod_fastcgi：

Install mod_fastcgi:

yum install  mod_fastcgi

启动服务：

service php-fpm start

重启Apache：

Restart Apache:

service httpd restart

5。阿帕奇与PHP-FPM配置

打开fastcgi.conf文件：

Open the fastcgi.conf file:

nano /etc/httpd/conf.d/fastcgi.conf

这添加到该文件的末尾：

Add this to the end of the file:

<IfModule mod_fastcgi.c>
                DirectoryIndex index.html index.shtml index.cgi index.php
                AddHandler php5-fcgi .php
                Action php5-fcgi /php5-fcgi
                Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi
                FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -host 127.0.0.1:9000 -pass-header Authorization
</IfModule>

在FastCgiWrapper后搜索，并确保它被设置为关闭，然后保存文件。

After that search after "FastCgiWrapper" and make sure it's set to "off" then save the file.

在/ usr / lib目录/ cgi-bin目录/目录必须存在的，所以我们创建它：

The /usr/lib/cgi-bin/ directory must exist, so we create it:

mkdir /usr/lib/cgi-bin/ 

如果已安装并启用mod_php的，我们需要禁用的/etc/httpd/conf.d/php.conf这么打开配置：

If mod_php is installed and enabled, we need to disable it so open the configuration at /etc/httpd/conf.d/php.conf:

nano /etc/httpd/conf.d/php.conf

注释掉的AddHandler和将AddType行，这样它看起来像在这里：

Comment out the AddHandler and AddType lines so it looks like here:

#
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
#
<IfModule prefork.c>
  LoadModule php5_module modules/libphp5.so
</IfModule>
<IfModule worker.c>
  LoadModule php5_module modules/libphp5-zts.so
</IfModule>
#
# Cause the PHP interpreter to handle files with a .php extension.
#
#AddHandler php5-script .php
#AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php
#
# Uncomment the following line to allow PHP to pretty-print .phps
# files as PHP source code:
#
#AddType application/x-httpd-php-source .phps

保存文件并重新启动Apache：

Save the file and restart Apache:

service httpd restart
