12 、实现一个 web 服务器
在server0上配置一个站点http://server0.example.com，然后执行以下步骤：
　　从http://classroom.example.com/materials/station.html下载文件，并且
　　将文件重命名为index.html,绝对不能修改此文件的内容。
　　将index.html拷贝到你的web服务器的DocumentRoot目录下。
　　来自example.com域的客户端可以访问此web站点。
　　来自my133t.org域的客户端拒绝访问此web站点。
　　备注： 网站的DocumentRoot如果题目没有指定，那么随意。

[root@server0 ~]# yum install httpd -y
[root@server0 ~]# rpm -ql httpd
/etc/httpd/conf/httpd.conf          主配置文件
/usr/share/doc/httpd-2.4.6/httpd-vhosts.conf    子配置文件
/usr/share/doc/httpd-2.4.6/httpd-manual.conf

[root@server0 ~]# cp /usr/share/doc/httpd-2.4.6/httpd-vhosts.conf /etc/httpd/conf.d/    重命名下
[root@server0 ~]# cp /usr/share/doc/httpd-2.4.6/httpd-manual.conf /etc/httpd/conf.d/

[root@server0 conf.d]# vim vhost.conf
<Directory "/var/www/html">
    <RequireAll>
        Require all granted
        Require not host .my133t.com
    </RequireAll>
</Directory>

<VirtualHost 172.25.0.11:80>           #直接写ip：port
    DocumentRoot "/var/www/html"
    ServerName server0.example.com
</VirtualHost>

[root@server0 ~]# cd /var/www/html/
[root@server0 html]# wget http://classroom.example.com/materials/station.html
[root@server0 html]# mv station.html index.html                                #只能cat 该文件， 检测:md5值匹配

[root@server0 conf.d]# firewall-cmd --permanent --add-service=http
[root@server0 conf.d]# firewall-cmd --permanent --add-rich-rule='rule family=ipv4 source address=172.25.0.0/24 service name=http accept'
[root@server0 conf.d]# firewall-cmd --permanent --add-rich-rule='rule family=ipv4 source address=172.17.10.0/24 service name=http reject'
[root@server0 conf.d]# firewall-cmd --reload 

[root@server0 ~]# systemctl enable httpd
[root@server0 ~]# systemctl restart httpd

[root@server0 ~]# firefox server0.example.com

　　

13 、配置安全 web 服务
站点http://server0.example.com配置TLS加密。
　　一个已经签名证书从http://classroom.example.com/pub/tls/certs/server0.crt获取
　　此证书的密钥从http://classroom.example.com/pub/tls/private/server0.key获取
　　此证书的授权信息从http://classroom.example.com/pub/example-ca.crt获取

[root@server0 ~]# yum install mod_ssl -y
[root@server0 ~]# rpm -ql mod_ssl
/etc/httpd/conf.d/ssl.conf

[root@server0 ~]# cat /etc/httpd/conf.d/ssl.conf   参考
100 SSLCertificateFile /etc/pki/tls/certs/localhost.crt
107 SSLCertificateKeyFile /etc/pki/tls/private/localhost.key
122 #SSLCACertificateFile /etc/pki/tls/certs/ca-bundle.crt

[root@server0 ~]# vim /etc/httpd/conf.d/vhost.conf
<Directory "/var/www/html">
    <RequireAll>
        Require all granted
        Require not host .my133t.com
    </RequireAll>
</Directory>

<VirtualHost 172.25.0.11:80>
    DocumentRoot "/var/www/html"
    ServerName server0.example.com
    SSLCertificateFile /etc/pki/tls/certs/server0.crt            3行直接添加到
    SSLCertificateKeyFile /etc/pki/tls/private/server0.key
    SSLCACertificateFile /etc/pki/tls/certs/example-ca.crt
</VirtualHost>

[root@server0 ~]# wget -O /etc/pki/tls/certs/server0.crt http://classroom.example.com/pub/tls/certs/server0.crt
[root@server0 ~]# wget -O /etc/pki/tls/private/server0.key http://classroom.example.com/pub/tls/private/server0.key
[root@server0 ~]# wget -O /etc/pki/tls/certs/example-ca.crt http://classroom.example.com/pub/example-ca.crt

[root@server0 ~]# firewall-cmd --permanent --add-service=https    加密服务https
[root@server0 ~]# firewall-cmd --reload 

[root@server0 ~]# systemctl restart httpd.service
[root@server0 ~]# systemctl enable httpd.service

[root@server0 ~]# firefox https://server0.example.com

　　

14 、配置虚拟主机
在server0上扩展你的web服务器，为站点http://www0.example.com创建一个虚拟主机，然后执行以下步骤：
　　设置DocumentRoot为/var/www/virtual
　　从http://classroom.example.com/materials/www.html下载文件并重命名为index.html，
　　不要对文件index.html内容做任何修改。
　　将index.htm文件放到虚拟主机的DocumentRoot目录下
　　确保floyd用户能够在/var/www/virtual目录下创建文件
　　注意：原始站点http://server0.example.com必须仍然能够访问。
　　站点的所用的域名网络中已有DNS服务器解析。

[root@server0 ~]# mkdir -pv /var/www/virtual

[root@server0 ~]# cd /var/www/virtual
[root@server0 virtual]# wget http://classroom.example.com/materials/www.html
[root@server0 virtual]# mv  www.html index.html

[root@server0 ~]# id floyd
[root@server0 ~]# useradd floyd
[root@server0 ~]# setfacl -m u:floyd:rwx /var/www/virtual/
[root@server0 ~]# getfacl /var/www/virtual/

[root@server0 ~]# vim /etc/httpd/conf.d/vhost.conf 

<Directory "/var/www/html">
    <RequireAll>
        Require all granted
        Require not host .my133t.com
    </RequireAll>
</Directory>

<VirtualHost 172.25.0.11:80>
    DocumentRoot "/var/www/html"
    ServerName server0.example.com
    SSLCertificateFile /etc/pki/tls/certs/server0.crt
    SSLCertificateKeyFile /etc/pki/tls/private/server0.key
    SSLCACertificateFile /etc/pki/tls/certs/example-ca.crt
</VirtualHost>

<VirtualHost 172.25.0.11:80>          添加虚拟主机www0
    DocumentRoot "/var/www/virtual"
    ServerName www0.example.com
</VirtualHost>

[root@server0 ~]# systemctl restart httpd.service
[root@server0 ~]# systemctl enable httpd.service
[root@server0 ~]# firefox http://www0.example.com

　　

15 、配置 web 内容的访问
在你的server0上的web服务器的DocumentRoot目录下创建一个名为private的目录，要求如下：
　　从http://classroom.example.com/materials/private.html下载一个文件副本到这个目录，并且重命名为index.html。
　　不要对这个文件的内容作任何修改。
　　从system1上，任何人都可以浏览private的内容，但是从其他系统就不能访问这个目录的内容。
　　（注意题目要求谁可以访问，灵活变化）
　　备注：此题目是接着上一题，所以这里的DocumentRoot指的就是上面的/var/www/virtual/。

[root@server0 ~]# mkdir -pv /var/www/virtual/private
[root@server0 ~]# cd /var/www/virtual/private

[root@server0 private]# wget http://classroom.example.com/materials/private.html
[root@server0 private]# mv private.html index.html

[root@server0 private]# vim /etc/httpd/conf/httpd.conf   主配置参考文件

[root@server0 private]# vim /etc/httpd/conf.d/vhost.conf
<Directory "/var/www/html">
    <RequireAll>
        Require all granted
        Require not host .my133t.com
    </RequireAll>
</Directory>

<VirtualHost 172.25.0.11:80>
    DocumentRoot "/var/www/html"
    ServerName server0.example.com
    SSLCertificateFile /etc/pki/tls/certs/server0.crt
    SSLCertificateKeyFile /etc/pki/tls/private/server0.key
    SSLCACertificateFile /etc/pki/tls/certs/example-ca.crt
</VirtualHost>

<VirtualHost 172.25.0.11:80>
    DocumentRoot "/var/www/virtual"
    ServerName www0.example.com
</VirtualHost>

<Directory "/var/www/virtual/private">         #### 添加
    Require all denied                    全部拒绝
    Require local                             本地访问
</Directory>

[root@server0 private]# systemctl restart httpd
[root@server0 private]# systemctl enable httpd
[root@server0 private]#
[root@server0 private]# firefox http://www0.example.com/private/index.html

　　

16 、实现动态 Web容 内容 [ [ 新版题库已经没有这题] ]
在server0上配置提供动态web内容，要求如下：
　　动态内容由名为webapp0.example.com的虚拟主机提供虚拟主机监听在端口8908
　　从http://classroom.example.com/materials/webinfo.wsgi下载一个脚本，然后放在适当的位置，
　　无论如何不要修改此文件的内容。客户端访问http://webapp0.example.com:8908/时应该接收到动态生成的web页面。
　　此站点http://webapp0.example.com:8908/。必须能够被example.com域内的所有系统访问。

[root@server0 ~]# mkdir -pv /var/www/webapp
[root@server0 ~]# cd /var/www/webapp
[root@server0 webapp]# wget http://classroom.example.com/materials/webinfo.wsgi

[root@server0 ~]# semanage port -l |grep http
[root@server0 ~]# semanage port -a -t http_port_t -p tcp 8908          注册selinux端口  （可以图形界面policycoreutils-gui包，命令：system-config-selinx）
Full path required for exclude: net:[4026532647].
Full path required for exclude: net:[4026532647].
[root@server0 ~]# semanage port -l |grep http

[root@server0 ~]# firewall-cmd --permanent --add-rich-rule='rule family=ipv4 source address=172.25.0.0/24 port port=8908 protocol=tcp accept'   #防火墙
success
[root@server0 ~]# firewall-cmd --reload 

[root@server0 ~]# yum install mod_wsgi.x86_64 -y
[root@server0 ~]# rpm -ql mod_wsgi
/usr/share/doc/mod_wsgi-3.4/README

[root@server0 ~]# vim /usr/share/doc/mod_wsgi-3.4/README
 WSGIScriptAlias /wsgi/ /usr/local/wsgi/scripts/

[root@server0 ~]# vim /etc/httpd/conf.d/vhost.conf

    <RequireAll>
        Require all granted
        Require not host .my133t.com
    </RequireAll>
</Directory>

<VirtualHost 172.25.0.11:80>
    DocumentRoot "/var/www/html"
    ServerName server0.example.com
    SSLCertificateFile /etc/pki/tls/certs/server0.crt
    SSLCertificateKeyFile /etc/pki/tls/private/server0.key
    SSLCACertificateFile /etc/pki/tls/certs/example-ca.crt
</VirtualHost>

    DocumentRoot "/var/www/virtual"
    ServerName www0.example.com
</VirtualHost>

<Directory "/var/www/virtual/private">
    Require all denied
    Require local
</Directory>

Listen 8908             #添加  监听8908端口
<VirtualHost 172.25.0.11:8908>
    DocumentRoot "/var/www/webapp"
    ServerName webapp0.example.com
    WSGIScriptAlias / /var/www/webapp/webinfo.wsgi
</VirtualHost>

[root@server0 ~]# systemctl restart httpd
[root@server0 ~]# systemctl enable httpd
[root@server0 ~]# firefox http://webapp0.example.com:8908/
