apache

一，apache信息
1.apache默認發佈文件
  /var/www/html/index.html

2.apache配置文件
  /etc/http/conf/httpd.conf          ##主配置文件
  /etc/http/conf.d/*.conf            ##子配置文件

3.apache默認發佈目錄
  /var/www/html
4.apache默認端口
  80端口

二，apache基本配置
1.修改默認發佈文件
vim /etc/http/conf/httpd.conf
  164      DirectoryIndex westos.html
systemctl restart httpd

2.修改默認發佈目錄
vim /etc/http/conf/httpd.conf
  120 DocumentRoot "westos/www/test"
  <Directory "westos/www/test">
        Require all granted
  </Directory>
systemctl restart httpd

3.apache的訪問設定
***設定IP的訪問***
vim /etc/httpd/conf/httpd.conf
  <Directory "/var/www/html/admin">                 ##允許所有人訪問admin目錄但拒絕240主機
        Order Allow,Deny
      Allow from All
    Deny from 172.25.254.240
  </Directory>
systemctl restart httpd

vim /etc/httpd/conf/httpd.conf
  <Directory "/var/www/html/admin">                 ##只允許240主機訪問admin目錄
        Order Deny,Allow
      Allow from 172.25.254.240
    Deny from All
  </Directory>
systemctl restart httpd
***設定用戶的訪問***
記着原密碼
htpassword -m /etc/httpd/accessuser admin
忘記原密碼
vim /etc/httpd/conf/httpd.conf
  <Directory "/var/www/html/admin">
        AuthUserFile /etc/httpd/accessuser                 ##用戶認證文件
    AuthName "Please input your name and password!!"   ##用戶認證提示信息
    AuthType basic                                     ##認證類型
    Require valid-user                                 ##認證用戶，認證文件中所有用戶都可以通過
    [Require user admin]                               ##只允許認證文件中的admin用戶訪問【二選一】
  </Directory>

三，apache語言支持（php html cgi）
*****html*****
默認支持

*****php*****

[root@localhost html]# yum install php -y

Loaded plugins: langpacks
rhel_dvd                                                 | 4.1 kB     00:00     
Package php-5.4.16-21.el7.x86_64 already installed and latest version
Nothing to do
[root@localhost html]# systemctl restart httpd
測試：訪問172.25.254.240/index.php

*****cgi*****
[root@localhost html]# mkdir cgi
[root@localhost html]# ls
admin.html  cgi  index.php  mysqladmin  westos.html
[root@localhost html]# cd cgi
[root@localhost cgi]# vim index.cgi
  #!/usr/bin/perl
  print "Content-type: text/html\n\n";
  print `date`;

[root@localhost cgi]# vim /etc/httpd/conf/httpd.conf
  <Directory "/var/www/html/cgi">
        Options +ExecCGI
        AddHandler cgi-script .cgi
  </Directory>
  173 <IfModule dir_module>
  174     DirectoryIndex index.cgi westos.html index.html
  175 </IfModule>

[root@localhost cgi]# getenforce
Enforcing
[root@localhost cgi]# setenforce 0
[root@localhost cgi]# chmod +x index.cgi
[root@localhost cgi]# systemctl restart httpd
測試：訪問172.25.254.240/cgi

四，apache虛擬主機
apache虛擬主機可以讓我們的一臺apache服務器在被訪問不同域名的時候顯示不同主頁
*****服務端*****
[root@localhost ~]# cd /var/www
1.建立測試頁
[root@localhost www]# mkdir virtual/news.westos.com/html -p             
[root@localhost www]# echo "<h1>news.westos.com's page" >virtual/news.westos.com/html/index.html
2.編寫配置文件
[root@localhost www]# cd /etc/httpd/conf.d
[root@localhost conf.d]# ls
autoindex.conf  php.conf  README  userdir.conf  welcome.conf
[root@localhost conf.d]# vim default.conf
   <Virtualhost _default_:80>                                       ##虛擬主機開啓的端口
    DocumentRoot "/var/www/html"                              ##虛擬主機的默認發佈目錄
    CustomLog "logs/default.log" combined                  ##虛擬主機日誌存放目錄
   </Virtualhost>

[root@localhost conf.d]# vim news.conf                     ##指定域名news.westos.com的訪問到指定默認發佈目錄中
   <Virtualhost *:80>
    ServerName "news.westos.com"
    DocumentRoot "/var/www/virtual/news.westos.com/html"
    Customlog "logs/news.log" combined
   </Virtualhost>
   <Directory "/var/www/virtual/news.westos.com/html">        ##默認發佈目錄的訪問授權
    Require all granted
   </Directory>

[root@localhost conf.d]# systemctl restart httpd
*****測試端*****
[root@localhost conf.d]# vim /etc/hosts
   172.25.254.240 news.westos.com www.westos.com

訪問：news.westos.com 或者 www.westos.com

五，https

https是HTTP的安全版，HTTPS的安全基礎是SSL，因此加密的詳細內容就需要SSL。

yum install mod_ssl -y                        
yum install crypto-utils -y                  

genkey www.westos.com                ##

這個進度條完了還會有第二個進度條，此時在shell中輸入字符（隨意輸）直到進度條完

vim /etc/httpd/conf.d/login.conf

   <Virtualhost *:443>
        ServerName "login.westos.com"
        DocumentRoot "/var/www/virtual/login.westos.com/html"
        CustomLog "logs/login.log" combined
        SSLEngine on
        SSLCertificateFile /etc/pki/tls/certs/www.westos.com.crt
        SSLCertificateKeyFile /etc/pki/tls/private/www.westos.com.key
   </Virtualhost>
   <Directory "/var/www/virtual/login.westos.com/html">
        Require all granted
   </Directory>
   <Virtualhost *:80>
        ServerName "login.westos.com"
        RewriteEngine on
        RewriteRule ^(/.*)$ https://%{HTTP_HOST}$1 [redirect=301]
   </Virtualhost>

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

#^(/.*)$                              ##客戶在地址欄中輸入的所有字符，不包括換行符

#https://                            ##定向成爲的訪問協議

#%{HTTP_HOST}             ##客戶請求主機

#$1                                  ##$1的值就是^(/.*)$的值

#[redirect=301]                ##臨時重定向（302表示永久重定向）

mkdir /var/www/virtual/login.westos.com/html -p

vim /var/www/virtual/login.westos.com/html/login.westos.com

   <h1>login.westos.com's page<h1>

vim /etc/httpd/conf/httpd.conf

    164    DirectoryIndex   login.westos.com  

測試：訪問login.westos.com時，其網址自動切換爲：https://login.westos.com
