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 <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"> 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/
