php相关配置（总结）

php路径没有加载图1 ：
图二禁用php.info的结果

[root@chy ~]# /usr/local/php/bin/php -i
(查看php的路径)
[root@chy 111.com]# vim index.php

错误日志的小案例

[root@chy php-5.6.30]# vim /data/wwwroot/111.com/2.php (写一个2.php)
[root@chy php-5.6.30]# curl -A "c" -x127.0.0.1:80 http://www.111.com/2.php -I

(状态码为500，为500的原因是2.php的语法故意写错了)

网站隔离（A,B网站互不影响,当一个网站被黑了，另一个网站没有影响）open_basedir

[root@chy php-5.6.30]# vim /usr/local/php/etc/php.ini 
open_basedir =/data/wwwroot/111.com/tmp/
(在php.ini下定义的是整个的网站并达不到需要的效果，如果需要实现每个网站都隔离需要在apache的虚拟配置文件里进行配置）
[root@chy php-5.6.30]# vi /usr/local/apache2.4/conf/extra/httpd-vhosts.conf 

    DocumentRoot "/data/wwwroot/111.com"
    ServerName www.111.com
    ServerAlias www.exaple.com 222.com
    #
     #
      #AllowOverride AuthConfig
      #AuthName "111.com user auth"
        #AuthType Basic
        #AuthUserFile /data/.htpasswd
       #require valid-user
      #
      #
      php_admin_value open_basedir "/data/wwwroot/111.com:/tmp/"
（针对不同的虚拟主机设置open_basedir,php_admin_value open_basedir "/data/wwwroot/111.com:/tmp/"主要配置）
