12、实现一个web服务器

[root@server0 ~]# yum install httpd -y
[root@server0 ~]# rpm -ql httpd      查看httpd产生的配置文件
/usr/share/doc/httpd-2.4.6/httpd-manual.conf
/usr/share/doc/httpd-2.4.6/httpd-vhosts.conf


[root@server0 ~]# vim /etc/httpd/conf.d/vhost-server0.conf
<Directory "/var/www/html">               网页文件存放的目录
        <RequireAll>                      控制特定主机（HOSTNAME）访问
                Require all granted                    允许所有主机访问
                Require not host .my133t.com           允许所有主机访问             
  
        </RequireAll>
</Directory>
<VirtualHost *:80>               虚拟主机，基于域名的,监听80端口
        DocumentRoot "/var/www/html"
        ServerName server0.example.com
</VirtualHost>


[root@server0 ~]# wget -O /var/www/html/index.html http://classroom.example.com/materials/station.html

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

[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 

　　

测试，浏览器访问server0.example.com
[root@server0 ~]# lab examrhce grade
[root@server0 ~]# firefox server0.example.com

　　

13、配置安全web服务 (https协议，mod_ssl服务)

[root@server0 ~]# yum install mod_ssl -y                


[root@server0 ~]# rpm -ql mod_ssl           查看mod_ssl生成的文件
/etc/httpd/conf.d/ssl.conf

[root@server0 ~]# cd /etc/httpd/conf.d/
[root@server0 conf.d]# cp ssl.conf ssl.conf.bak   备份配置文件

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

107 SSLCertificateFile /etc/pki/tls/certs/server0.crt
115 SSLCertificateKeyFile /etc/pki/tls/private/server0.key
129 SSLCACertificateFile /etc/pki/tls/certs/example-ca.crt


查看密钥证书的保存路径后，再到目录下载文件
[root@server0 ~]# cd /etc/pki/tls/
[root@server0 tls]# ll
[root@server0 tls]# cd certs/
[root@server0 certs]# wget http://classroom.example.com/pub/tls/certs/server0.crt
[root@server0 certs]# wget http://classroom.example.com/pub/example-ca.crt

[root@server0 certs]# cd ..
[root@server0 tls]# cd private/
[root@server0 private]# wget http://classroom.example.com/pub/tls/private/server0.key



[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 conf.d]# systemctl restart httpd.service 
[root@server0 conf.d]# systemctl enable httpd.service
[root@server0 ~]# firewall-cmd --permanent --add-service=https    https协议安全
[root@server0 ~]# firewall-cmd --reload 

　

小技巧：
如果配置文件没有备份，配置文件不能还原，写的乱七八糟
删除配置文件，remove服务httpd ，重新安装，
就会生成新的配置文件

　　

　

14、配置虚拟主机

[root@server0 ~]# mkdir /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 conf.d]# cp vhost-server0.conf vhost-www0.conf
[root@server0 ~]# vim /etc/httpd/conf.d/vhost-www0.conf
<Directory "/var/www/virtual">          注意virtual
        <RequireAll>
                Require all granted
                Require not host .my133t.com
        </RequireAll>
</Directory>
<VirtualHost *:80>
        DocumentRoot "/var/www/virtual"   注意virtual
        ServerName www0.example.com       注意www0.example
</VirtualHost>


[root@server0 ~]# systemctl restart httpd
[root@server0 ~]# firefox www0.example.com

　　

15、配置web内容的访问

[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 ~]# vim /etc/httpd/conf.d/vhost-www0.conf 
###追加以下内容
<Directory "/var/www/virtual/private">               注意virtual
	Require all denied　　　　　　　　　　　　　　注意没有<Requireall>
	Require local
</Directory>

[root@server0 ~]# systemctl restart httpd

[root@server0 ~]# firefox www0.example.com/private/index.html

　　

16、实现动态Web内容 

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


[root@server0 webapp]# getenforce   #selinux
Enforcing
[root@server0 webapp]# semanage port -l | grep http                    查看80端口设置
[root@server0 webapp]# semanage port -a -t http_port_t -p tcp 8908   注册端口失败（内存不足，server0内存设置为2G）
Killed

关机 shutdown 安全关机  shutdown -c （立即关机）
　　  init 0 
reboot 重启


[root@server0 ~]# semanage port -a -t http_port_t -p tcp 8908
Full path required for exclude: net:[4026532575].
Full path required for exclude: net:[4026532575].
[root@server0 webapp]# semanage port -l | grep 8908


[root@server0 conf.d]# rpm -ql mod_wsgi 
/usr/share/doc/mod_wsgi-3.4/README                 #参考文档
    WSGIScriptAlias /wsgi/ /usr/local/wsgi/scripts/ 

[root@server0 conf.d]# cat vhost-server0.conf

[root@server0 ~]# vim /etc/httpd/conf.d/vhost-webapp0.conf

Listen 8908                                    注意listen
<Directory "/var/www/webapp">    注意webapp
                Require all granted
</Directory>
<VirtualHost *:8908>
        DocumentRoot "/var/www/webapp"
        ServerName webapp0.example.com
        WSGIScriptAlias / /var/www/webapp/webinfo.wsgi    注意格式
</VirtualHost>


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

[root@server0 webapp]# firefox http://webapp0.example.com:8908/

 

图形界面配置端口  （内存设置2G，注册成功）
[root@server0 ~]#  yum install policycoreutils-gui.x86_64 -y
[root@server0 ~]# system-config-selinux
