apache的虚拟主机加密和apache的网页重写

关闭火墙，配置好加密证书

[root@desktop upload]# cd /etc/httpd/conf.d/

[root@desktop conf.d]# ls

autoindex.conf manual.conf php.conf ssl.conf userdir.conf

default.conf news.conf README tmprequest welcome.conf

[root@desktop conf.d]# vim news.conf ##在vim 中sp /etc/httpd/conf.d/ssl.conf打开俩个窗口，用ctrl+w进行选择

ServerName news.westos.com

RewriteEngine on

RewriteRule ^(/.*)$ https://%{HTTP_HOST}$1 [redirect=301]

</Virtualhost>

Require all granted

</Directory>

serverName news.westos.com

DocumentRoot /var/www/virtual/news/html

Customlog logs/news-443.log combined

SSLEngine on

SSLCertificateFile /etc/pki/tls/certs/www.westos.com.crt##证书目录

SSLCertificateKeyFile /etc/pki/tls/private/www.westos.com.key

</Virtualhost>

[root@desktop conf.d]# vim default.conf

DocumentRoot /var/www/html

CustomLog logs/default.log combined

</Virtualhost>

[root@desktop conf.d]# mkdir -p /var/www/virtual/news/html/

[root@desktop conf.d]# vim /var/www/virtual/news/index.html

hello word

测试 http://news.westos.com 自动变为https://news.westos.com/

PHP：

cd /var/www/html/

vim index.php

<?php

phpinfo ();php检测页面

vim /etc/httpd/conf/httpd.conf

163 <IfModule dir_module>

164 DirectoryIndex index.php index.html优先读取php

yum install php -y安装php

systemctl restart httpd重启服务

CGI网络配置（http://172.25.254.126/manual选择CGI查看需要添加的参数配置）

yum install httpd-manual -y

cd /etc/httpd/conf.d/

cd /var/www/html/

mkdir cgi

cd cgi/

vim index.cgi

#!/usr/bin/perl

print "Content-type: text/html\n\n";##网页显示时间

print `date`;

perl index.cgi ##检测CGI是否可用

vim /etc/httpd/conf.d/default.conf

在后面加入

<Directory "/var/www/html/cgi">##读取文件

Options +ExecCGI##有执行权限

AddHandler cgi-script .cgi

</Directory>

cd /var/www/

[root@desktop cgi]# cd /var/www/

[root@desktop www]# ls -Zd cgi-bin/

drwxr-xr-x. root root system_u:object_r:httpd_sys_script_exec_t:s0 cgi-bin/

[root@desktop www]# semanage fcontext -a -t httpd_sys_script_exec_t '/var/www/html/cgi(/.*)?'##更改安全上下文

[root@desktop www]# cd html/

[root@desktop html]# cd cgi/

[root@desktop cgi]# ls

index.cgi

[root@desktop cgi]# chmod +x index.cgi##给index.cgi权限

火墙和selinux要关掉

测试http://172.25.254.126/cgi/index.cgi

[root@desktop html]# yum install mariadb -y

[root@desktop html]# yum install php-mysql.x86_64 -y

[root@desktop html]# yum install mariadb-server.x86_64

[root@desktop html]# systemctl start mariadb

[root@desktop html]# mysql_secure_installation

[root@desktop upload]# yum install php

[root@desktop cgi]# mv Discuz_X3.2_SC_UTF8.zip /var/www/html/

[root@desktop cgi]# cd /var/www/html/

[root@desktop html]# ls

cgi Discuz_X3.2_SC_UTF8.zip index.php

[root@desktop html]# unzip Discuz_X3.2_SC_UTF8.zip

[root@desktop html]# ls

cgi Discuz_X3.2_SC_UTF8.zip index.php readme upload utility

[root@desktop html]# chmod 777 upload/ -R##给upload目录权限

[root@desktop html]# setenforce 0

[root@desktop ~]# systemctl restart httpd.service

正向代理

代理方：

yum install squid -y安装服务

vim /etc/squid/squid.conf

56 http_access allow all允许所有访问

62 cache dir ufs /var/spool/squid 100 16 256

systemctl start squid开启服务

被代理方进行测试

反向代理

服务端：

yum install squid安装服务（需要没有http）

vim /etc/squid/squid.conf修改配饰文件

56 http_access allow all允许所有人访问

58 # Squid normally listens to port 3128

59 http_port 80 vhost vport使用80端口（虚拟主机虚拟端口）

60 cache_peer 172.25.254.25 parent 80 0 no-query访问ip 父级端口邻居端口不使用邻居端口

61 # Uncomment and adjust the following to add a disk cache directory.

62 cache_dir ufs /var/spool/squid 100 16 256缓存位置

轮询

vim /etc/squid/suid.conf

56 http_access allow all

58 # Squid normally listens to port 3128

59 http_port 80 vhost vport

60 cache_peer 172.25.254.25 parent 80 0 no-query originserver round-robin name =web1轮询一ip

61 cache_peer 172.25.254.24 parent 80 0 no-query originserver round-robin name =web2轮询二ip

62 cache_peer_domain web1 web2 www.westos.com 轮询所对应的域名

63 # Uncomment and adjust the following to add a disk cache directory.

64 cache_dir ufs /var/spool/squid 100 16 256
