测试了个简单的PHP程序返回500异常。
测试了个简单的PHP程序返回500错误。。。
操作系统为UBUNTU12,APACHE2安装无误
PHP是APT-EGT安装的PHP5,安装过程我都仔细瞅了,没提示错误.
弄好了之后就按照国际惯例,HELLOWORLD了一下,结果:
CHROME提示:
=================================================================
服务器错误
网站在检索 http://192.168.1.107/helloworld.php 时遇到错误。 该网站可能关闭进行维护或配置不正确。
=================================================
IE提示:此错误(HTTP 500 内部服务器错误)意味着你正在访问的网站出现了服务器问题,此问题阻止了该网页的显示。
====================================
PHP代码如下:
echo "hello world";
?>
PHP5重新安装了也一样,求教为什么。。。
------解决方案--------------------
PHP没有解析?
------解决方案--------------------
就算解析了,也要这样——浏览器啊
echo "
";<br>echo "hello world";<br>?><br><br><br><font color="#FF8000">------解决方案--------------------</font><br><pre class='brush:php;toolbar:false;'><?php<br />phpinfo();<br />?>
这个打印得出吗?
------解决方案--------------------
你重新apt-get install 一次吧 把 apache linux mysql 都给装上,现在在ubuntu 下装这个比在win下简单多了。基本上正常安装的话不会存在有什么问题。有问题的基本上都是自己编译的部分
------解决方案--------------------
777是错的
问题在于你执行php的进程的权限
请检查你用哪个用户执行的php
然后
chown username:username php_dir -R
------解决方案--------------------
777是最大权限
针对不同的用户的
rwx rwx rwx 你在linux直接看是这样的 分别对应 所有者权限user 用户组权限group 其他人权限other
r-读 w-写 x-执行
rwx都有为4+2+1=7
假设r-w 即没有写的权限 4+0+1=5
一般情况744
即 rwx r-- r--
------解决方案--------------------
将属主指定给apache的执行用户,
一般默认为apache就可以了。
chown apache:apache helloword.php
------解决方案--------------------
如果是加载so模式使用php,那么
ps -ef
------解决方案--------------------
grep httpd
------解决方案--------------------
grep -v grep
然后看最左一列,就是用户名
------解决方案--------------------
你不做服务器这块,linux 了解一些就好,真要做了,你会发现linux 挺有意思的, 我反而觉得windows 的产品烂,低效,折腾着麻烦。 上次就设置一个sql 的密码,硬是折腾半天~
