apache的基本配置

1.修改默认发布文件

<Directory "/westos/www/test">

         Require  all granted

</Directory>

systemctl  restart  httpd

当selinux是enforcing状态

vim  /etc/httpd/conf/httpd.conf

120   DocumentRoot "/westos/www/test"

<Directory "/westos/www/test">

         Require  all granted

</Directory>

systemctl  restart  httpd

semanage  fcontext  -a  -t httpd_sys_content_t  '/westos(/.*)?'

restorecon  RvvF  /westos

3.apache的访问控制

vim  /etc/httpd/conf/httpd.conf    

<Directory  "/var/www/admin">            #允许所有人访问admin目录但拒绝118访问

        Order  Allow,Deny

        Allow  from  All

        Deny from  172.25.254.118

</Directory>

<Directory  "/var/www/admin">            #拒绝所有人访问admin目录但允许118访问

        Order  Deny,Allow

        Allow  from  172.25.254.118

        Deny from  All

</Directory>

4.设定用户的访问

htpasswd  -m  /etc/httpd/accessuser   admin

vim  /etc/httpd/conf/httpd.conf

<Directory  "/var/www/admin">

       AuthUserfile  /etc/httpd/accessuser                   #用户认证文件

       AuthName  "Please  input  your  name  and  password !!"  #用户认证提示信息

       AuthType  basic                                        #认证类型

       Require  valid-user                          #认证用户，认证文件中所有用户都可以通过

</Directory>

4.apache语言支持

php    html   cgi

html语言默认支持

php语言

yum install  php -y

cd  /var/www/html

vim index.php

<?php

             phpinfo();

?>

systemctl   restart  httpd

测试 ：访问172.25.254.118/index.php

cgi语言

mkdir  /var/www/html/cgi

vim  index.cgi

#!/usr/bin/perl

print "Content-type: text/html\n\n";

print `date`;

vim  /etc/httpd/conf/httpd.conf

<Directory  "/var/www/html/cgi">

         Options  +ExecCGI

         AddHandler  cgi-scripts  .cgi

</Directory>

要给index.cgi文件加可执行权限，selinux不再enforcing状态

systemctl  restart httpd

apache的虚拟主机

1.定义

可以让我们的一台apache服务器在被访问不同域名的时候显示不同的主页

2.建立测试页

mkdir  /var/www/virtual

cd  /var/www

mkdir  virtual/money.westos.com/html  -p

mkdir  virtual/news.westos.com/html  -p

echo  "money.westos.com's page" >virtual/money.westos.com/html/index.html

echo  "news.westos.com's page" >virtual/news.westos.com/html/index.html

3.配置

vim  /etc/httpd/conf.d/default.conf       #未指定域名的访问都访问default

<Virtualhost  _default_:80>             #虚拟主机开启的端口

         DocumentRoot   "/var/www/html"   #虚拟主机默认发布目录

        Customlog "logs/default.log" combined    #虚拟主机日志

</Virtualhost>

vim /etc/httpd.conf.d/news.conf         #指定域名news.westos.com的访问到指定默认发布目录中

<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">  #默认发布目录的访问授权

         Require  all  granted

</Directory>

cp /etc/httpd/conf.d/news   /etc/httpd/conf.d/money

vim  /etc/httpd/conf.d/money

:%s/news/money/g

4.测试

在浏览器所在的主机中

vim  /etc/hosts
