4、建立httpd服务器(基于编译的方式进行),要求:

     提供两个基于名称的虚拟主机:

   (a)www1.stuX.com,页面文件目录为/web/vhosts/www1;错误日志为/var/log/httpd/www1.err,访问日志为/var/log/httpd/www1.access;

   (b)www2.stuX.com,页面文件目录为/web/vhosts/www2;错误日志为/var/log/httpd/www2.err,访问日志为/var/log/httpd/www2.access;

   (c)为两个虚拟主机建立各自的主页文件index.html,内容分别为其对应的主机名;

   (d)通过www1.stuX.com/server-status输出httpd工作状态相关信息,且只允许提供帐号密码才能访问(status:status);

5、为第4题中的第2个虚拟主机提供https服务,使得用户可以通过https安全的访问此web站点;

  (1)要求使用证书认证,证书中要求使用的国家(CN)、州(HA)、城市(ZZ)和组织(MageEdu);

  (2)设置部门为Ops,主机名为www2.stuX.com,邮件为admin@stuX.com;

6、在LAMP架构中,请分别以php编译成httpd模块形式和php以fpm工作为独立守护进程的方式来支持httpd,列出详细的过程。

1.一次完整的http请求处理过程:

         (1)建立或处理连接:接收请求或拒绝请求;

         (2)接收请求:接收来自于网络上的主机请求报文中对某特定资源的一次请求的过程;

         (3)处理请求:对请求报文进行解析,获取客户端请求的资源及请求方法等相关信息;

         (4)访问资源:获取请求报文中请求的资源;

         (5)构建响应报文:

         (6)发送响应报文:

         (7)记录日志:

2.httpd所支持的处理模型有哪些,他们的分别使用于哪些环境。

         prefork:多进程模型,每个进程响应一个请求;

                   一个主进程:负责生成子进程及回收子进程;负责创建套接字;负责接收请求,并将其派发给某子进程进行处理;

                   n个子进程:每个子进程处理一个请求;

                   工作模型:会预先生成几个空闲进程,随时等待用于响应用户请求;最大空闲和最小空闲

         worker:多进程多线程模型,每线程处理一个用户请求;

                   一个主进程:负责生成子进程;负责创建套接字;负责接收请求,并将其派发给某子进程进行处理;

                   多个子进程:每个子进程负责生成多个线程;

                   每个线程:负责响应用户请求;

                   并发响应数量:m*n

                            m:子进程数量

                            n:每个子进程所能创建的最大线程数量;

         event:事件驱动模型,多进程模型,每个进程响应多个请求;

                   一个主进程 :负责生成子进程;负责创建套接字;负责接收请求,并将其派发给某子进程进行处理;

                   子进程:基于事件驱动机制直接响应多个请求;

3.源码编译安装LAMP环境(基于wordpress程序),并写出详细的安装、配置、测试过程。

4、建立httpd服务器(基于编译的方式进行),要求: 提供两个基于名称的虚拟主机:

   (a)www1.stuX.com,页面文件目录为/web/vhosts/www1;错误日志为/var/log/httpd/www1.err,访问日志为/var/log/httpd/www1.access;

   (b)www2.stuX.com,页面文件目录为/web/vhosts/www2;错误日志为/var/log/httpd/www2.err,访问日志为/var/log/httpd/www2.access;

   (c)为两个虚拟主机建立各自的主页文件index.html,内容分别为其对应的主机名;

   (d)通过www1.stuX.com/server-status输出httpd工作状态相关信息,且只允许提供帐号密码才能访问(status:status);

[root@localhost ~]# mkdir -pv/web/vhosts/{www1,www2}                          ###创建文件目录

[root@localhost ~]# mkdir -pv/var/log/httpd

[root@localhost ~]# echo"

www1.stuX.com

" > /web/vhosts/www1/index.html                   ###主页文件内容

[root@localhost ~]# echo"

www2.stuX.com

                   Requireall granted

 

        

        

                   SetHandlerserver-status

                   AuthTypeBasic

                   AuthName"Enter username and password"

                   AuthUserFile"/etc/httpd24/.htpasswd"

                   Requireuser status

        

 

 

    

         ServerNamewww2.stux.com

         DocumentRoot"/web/vhosts/www2"

         ErrorLog"/var/log/httpd/www2.err"

总结:编译安装的2.4虚拟主机配置文件与2.2有所区别

对于基于IP的访问控制做了修改,不再支持使用order, allow, deny这些机制,而是统一使用require进行

基于主机名的虚拟主机不再需要NameVirtualHost指令

注意:任意目录下的页面只有显式授权才能被访问;

5、为第4题中的第2个虚拟主机提供https服务,使得用户可以通过https安全的访问此web站点;

  (1)要求使用证书认证,证书中要求使用的国家(CN)、州(HA)、城市(ZZ)和组织(MageEdu);

  (2)设置部门为Ops,主机名为www2.stuX.com,邮件为admin@stuX.com;

###测试用,CA与httpd位于同一主机

###首先,创建私有CA,在服务器创建证书签署请求以及CA签证

[root@localhost ~]# rpm -q openssl

openssl-1.0.1e-57.el6.x86_64

[root@localhost ~]# (umask 077;opensslgenrsa -out /etc/pki/CA/private/cakey.pem 4096)                 ###创建私钥
