1.搭建web服务实现多个虚拟主机

RHEL6 httpd-2.2.15 RHEL7 httpd-2.4.6-
关键配置如下：
要使用虚拟主机功能需要打开下面参数，只要将主配置文件中的选项前的#号去掉即可。

NameVirtualHost *:80 创建虚拟主机< VirtualHost *:80> 网站根目录位置    DocumentRoot /var/www/test123.com  虚拟主机名    ServerName www.test123.com 错误日志存放位置    ErrorLog logs/test123.com-error_log 访问日志存放位置    CustomLog logs/test123.com-access_log common< /VirtualHost>

==========
详细步骤：
[root@rhel6 conf.d]# rpm -q httpd
httpd-2.2.15-29.el6_4.x86_64
[root@rhel6 ~]# yum install -y elinks
[root@rhel6 ~]# vim /etc/httpd/conf/httpd.conf
[root@rhel6 ~]# cd /etc/httpd/conf.d
[root@rhel6 conf.d]# ls
mod_dnssd.conf README welcome.conf
[root@rhel6 conf.d]# vim test123.conf
[root@rhel6 conf.d]# mkdir /var/www/test123.com
[root@rhel6 conf.d]# echo this is www.test123.com > /var/www/test123.com/index.html
[root@rhel6 conf.d]# cp test123.conf xiaoming.conf
[root@rhel6 conf.d]# vim xiaoming.conf
[root@rhel6 conf.d]# mkdir /var/www/xiaoming.com
[root@rhel6 conf.d]# echo this is www.xiaoming.com > /var/www/xiaoming.com/index.html
[root@rhel6 conf.d]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: apr_sockaddr_info_get() failed for rhel6
httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ]
[root@rhel6 conf.d]# vim /etc/hosts
[root@rhel6 conf.d]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.25.0.11 www.test123.com
172.25.0.11 www.xiaoming.com
[root@rhel6 conf.d]# links www.test123.com
[root@rhel6 conf.d]# links www.xiaoming.com

2.项目要求：基于主机的访问控制

允许所有主机访问www.test123.com，除了172.25.0.10这台主机

<Directory "/var/www/test123.com">Order allow,denyAllow from allDeny from 172.25.0.10</Directory>

Order参数实现主机访问控制，allow from 允许谁能访问，all代表所有主机
deny from 不允许谁访问，172.25.0.10是需要禁止访问的主机的ip地址，如果要跟多个，可以用空格分割。

注意，主机的访问控制是对目录实现的

详细步骤

[root@rhel6 conf.d]# vim test123.conf <VirtualHost *:80>    DocumentRoot /var/www/test123.com    ServerName www.test123.com    ErrorLog logs/test123.com-error_log    CustomLog logs/test123.com-access_log common</VirtualHost><Directory "/var/www/test123.com">    Order allow,deny    Allow from all    Deny from 172.25.0.10</Directory>

[root@rhel6 conf.d]# service httpd restartStopping httpd:                                            [  OK  ]Starting httpd: httpd: apr_sockaddr_info_get() failed for rhel6httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName                                                           [  OK  ]

1. 在网站根目录下创建子目录

2. 设定子目录的主机访问控制

3. 测试

[root@rhel6 ~]# cd /var/www[root@rhel6 www]# lltotal 24drwxr-xr-x. 2 root root 4096 Aug  2  2013 cgi-bindrwxr-xr-x. 3 root root 4096 Jul  2  2015 errordrwxr-xr-x. 2 root root 4096 Sep 28 10:18 htmldrwxr-xr-x. 3 root root 4096 Jul  2  2015 iconsdrwxr-xr-x. 2 root root 4096 Sep 28 10:40 test123.comdrwxr-xr-x. 2 root root 4096 Sep 28 10:42 xiaoming.com[root@rhel6 www]# cd test123.com/[root@rhel6 test123.com]# mkdir test[root@rhel6 test123.com]# touch test/file{1..10}[root@rhel6 test123.com]# lltotal 8-rw-r--r--. 1 root root   26 Sep 28 10:40 index.htmldrwxr-xr-x. 2 root root 4096 Sep 28 11:30 test[root@rhel6 conf.d]# vim test123.conf <VirtualHost *:80>    DocumentRoot /var/www/test123.com    ServerName www.test123.com    ErrorLog logs/test123.com-error_log    CustomLog logs/test123.com-access_log common</VirtualHost><Directory "/var/www/test123.com">    Order allow,deny    Allow from all    Deny from 172.25.0.10</Directory>*针对子目录test做的主机访问控制*<Directory "/var/www/test123.com/test">    Options Indexes     Order allow,deny    Allow from all</Directory>[root@rhel6 conf.d]# service httpd reloadReloading httpd:

rhel7作为客户端进行测试

=================================
3.项目要求，基于用户访问控制 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
对www.test123.com/test设置用户和密码jack和tom密码都是test123

1）修改配置文件，添加用户认证相关的配置
2）通过htpasswd创建用户和密码
3）重启服务
4）客户端测试

详细步骤：

[root@rhel6 ~]# vim /etc/httpd/conf.d/test123.conf<Directory "/var/www/test123.com/test">Options Indexes MultiViews FollowSymLinksAllowOverride AuthConfig#仅有网页认证 ( 账号密码 ) 可覆写 ;AuthName "student"#在要你输入账号与密码的对话窗口中 , 出现的『提示字符』AuthType basic# 认证的类型AuthUserFile "/etc/httpd/test"# 这个目录所使用的账号密码配置文件Require valid-user# 后面接可以使用的账号 , 此处是让该密码文件内的用户都能够登入Order allow,denyAllow from all</Directory>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[root@rhel6 conf.d]# htpasswd -cmb   /etc/httpd/test tom test123Adding password for user tom[root@rhel6 conf.d]# htpasswd -mb /etc/httpd/test jack test123 Adding password for user jack[root@rhel6 conf.d]# cat /etc/httpd/testtom:$apr1$ODWlTN5b$BspUhjoyT6RexJGv7aqaL/jack:$apr1$kx5gyFtP$eEnmSGfSOJxzuK7g/frPd/[root@rhel6 conf.d]# service httpd restartStopping httpd:      [  OK  ]Starting httpd: httpd: apr_sockaddr_info_get() failed for rhel6httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName     [  OK  ]

htpasswd 创建网页用户认证的用户名和密码工具    -c  新建保存用户名和密码的文件    -m  通过md5来加秘密    -b  将密码放在终端行中显示第一次创建使用-c参数，当已经存在test文件时，就不需要再使用-c参数了#注意在配置文件中通过 AuthUserFile 指定的文件一定要和你用htpasswd创建的文件名一致 "/etc/httpd/test"

综合项目：

通过APACHE搭建两个虚拟主机 www.batmanX.com www.supermanX.com
要求
1.访问网址 www.batmanX.com/justice 时需要用户认证，用户batman，密码test123可以访问
2.访问网址 www.supermanX.com 时，只允许172.25.0.10访问，其他主机都不允许
