  • Redhat Server 5.7 安装配置PHP

    PHP的简介

           PHP于1994年由Rasmus Lerdorf创建,刚刚开始是Rasmus Lerdorf 为了要维护个人网页而制作的一个简单的用Perl语言编写的程序。这些工具程序用来显示 Rasmus Lerdorf 的个人履历,以及统计网页流量。后来又用C语言重新编写,包括可以访问数据库。他将这些程序和一些表单直译器整合起来,称为 PHP/FI。PHP/FI 可以和数据库连接,产生简单的动态网页程序.......[参考百科]

    PHP安装配置

         首先去官网http://cn2.php.net/downloads.php下载最新版的安装包或你需要的版本,本次实验的系统环境为Red Hat Enterprise Linux Server release 5.7 64bit。这篇文章是安装配置nagios的过程

    报错“configure: error: xml2-config not found. Please check your libxml2 installation.”是因为缺少libxml2相关的包libxml2-devel, 如下所示,先检查已经安装了那些libxml2相关的包

    clip_image012

    接下来配置Apache服务,关于Apache的安装,可以参考我的博客Linux系统安装Appach 2.4.6

    PHP环境配置

    Step 1: Apache环境配置

    首先找到Apache的配置文件配置文件/usr/local/apache/conf/httpd.conf (我Apache服务安装目录为/usr/local/apache)

    找到

    #User daemon

    #Group daemon

    修改为

    User nagios

    Group nagios

    另外找到ServerName www.example.com:80 ,在下面增加ServerName添加服务器的IP地址

    clip_image014

    另外找到下面配置,增加index.php

    <IfModule dir_module>

    DirectoryIndex index.html

    </IfModule>

    clip_image016

    接下来找到<IfModule mime_module>,在后面增加配置信息AddType application/x-httpd-php .php,如下所示

    clip_image018

    出于安全考虑,一般访问nagios的安全监控界面必须经过授权才能访问(不要那么,安装配置PHP是安装配置nagios的过程,如果大家只是为了安装配置PHP环境,完全可以跳过下面),这需要增加验证配置,即在httpd.conf 文件最后添加如下信息:

    clip_image020

    Step 2:创建apache目录验证文件

    [root@getlnx05 conf]#  /usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd kerry

    clip_image022

    这样就在/usr/local/nagios/etc 目录下创建了一个htpasswd 验证文件,当通过http://192.168.xx.xxx/nagios/ 访问时就需要输入用户名和密码了。当然验证文件的密码是加密过的,如下所示:

    [root@getlnx05 conf]# cat /usr/local/nagios/etc/htpasswd

    kerry:$apr1$H1bHFvhH$q.bsSARuh4Ns2Z5G9hmQN.

    [root@getlnx05 conf]#

    image

    Step 3:重启Apache服务

    [root@getlnx05 conf]# /usr/local/apache/bin/apachectl restart

    AH00526: Syntax error on line 515 of /usr/local/apache/conf/httpd.conf:

    AuthUserFile takes one argument, text file containing user IDs and passwords

    [root@getlnx05 conf]#

    用vi打开/usr/local/apache/conf/httpd.conf文件,定位到515行(下面红色的哪一行),后面的哪一行汉字注释变成导致,如下图所示:

    Code Snippet
    1. #setting for nagios
    2.  
    3. ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
    4.  
    5. <Directory "/usr/local/nagios/sbin">
    6.  
    7. AuthType Basic
    8.  
    9. Options ExecCGI
    10.  
    11. AllowOverride None
    12.  
    13. Order allow,deny
    14.  
    15. Allow from all
    16.  
    17. AuthName "Nagios Access"
    18.  
    19. AuthUserFile /usr/local/nagios/etc/htpasswd //用于此目录访问身份验证的文件
    20.  
    21. Require valid-user
    22.  
    23. </Directory>
    24.  
    25. Alias /nagios "/usr/local/nagios/share"
    26.  
    27. <Directory "/usr/local/nagios/share">
    28.  
    29. AuthType Basic
    30.  
    31. Options None
    32.  
    33. AllowOverride None
    34.  
    35. Order allow,deny
    36.  
    37. Allow from all
    38.  
    39. AuthName "nagios Access"
    40.  
    41. AuthUserFile /usr/local/nagios/etc/htpasswd
    42.  
    43. Require valid-user
    44.  
    45. </Directory>

    clip_image024

    将这一行注释清除后,重启Apache服务,OK,问题解决,打开http://192.168.7.223/nagios/进入网站,点击其它页面发现乱码,这是因为Apache没有开启cgi脚本的缘故。进入apache的主配置文件httpd.conf将#LoadModule cgid_module modules/mod_cgid.so前的注释符号去掉,重启Apache服务即可解决问题

    clip_image026
