CentOS7配置httpd虚拟主机教程

本实验旨在CentOS7系统中，httpd-2.4配置两台虚拟主机，主要有以下要求：

(1) 提供两个基于名称的虚拟主机：

　　www1.stuX.com，页面文件目录为/web/vhosts/www1；错误日志为/var/log/httpd/www1/error_log，访问日志为/var/log/httpd/www1/access_log；
　　www2.stuX.com，页面文件目录为/web/vhosts/www2；错误日志为/var/log/httpd/www2/error_log，访问日志为/var/log/httpd/www2/access_log；

(2) 通过www1.stuX.com/server-status输出其状态信息，且要求只允许提供账号的用户访问；

(3) www1不允许192.168.1.0/24网络中的主机访问；

查看系统版本和httpd版本

[root@host ~]$httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:  Nov 14 2016 18:04:44
[root@host ~]$cat /etc/centos-release
CentOS Linux release 7.3.1611 (Core) 

启动httpd，测试能否正常运行

[root@host ~]$systemctl start httpd.service
[root@host ~]$systemctl status httpd.service
● httpd.service - The Apache HTTP Server

使用curl命令访问

[root@host ~]$ip a show ens38  # 查看ip
3: ens38: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
  link/ether 00:0c:29:dc:18:5f brd ff:ff:ff:ff:ff:ff

  inet6 fe80::20c:29ff:fedc:185f/64 scope link
    valid_lft forever preferred_lft forever
[root@host ~]$curl http://192.168.55.128    # 访问
<!DOCTYPE>
<h1>

创建指定文件目录

[root@host conf.d]$mkdir -pv /web/vhosts/www1
[root@host conf.d]$mkdir -pv /web/vhosts/www2
[root@host conf.d]$mkdir -pv /var/log/httpd/www2
[root@host conf.d]$mkdir -pv /var/log/httpd/www1

根据要求填写虚拟主机配置信息

# path /etc/httpd/conf.d/vir.conf   # 配置文件全路径
#virtual host 1  　　# 虚拟主机1的配置
<VirtualHost 192.168.55.128:80>
  ErrorLog "/var/log/httpd/www1/error_log"
  CustomLog "/var/log/httpd/www1/access_log" combined
  <Location /server-status>
    SetHandler server-status
  </Location>
  <Directory /web/vhosts/www1>
    <RequireAll>
    Require all granted
    Require not ip 192.168.1
    </RequireAll>
  </Directory>
</VirtualHost>
# virtual host 2   # 虚拟主机2的配置
<VirtualHost 192.168.55.128:80>
  ServerName www2.stuX.com
  DocumentRoot "/web/vhosts/www2"
  ErrorLog "/var/log/httpd/www2/error_log"
  CustomLog "/var/log/httpd/www2/access_log" combined
  <Directory /web/vhosts/www2>
    <RequireAll>
    　　Require all granted
    </RequireAll>
  </Directory>
</VirtualHost>

创建www1和www2的index页面

[root@host conf.d]$cat /web/vhosts/www1/index.html
welcome to www1
thank you
[root@host conf.d]$cat /web/vhosts/www2/index.html
welcome to www2
thank you

重载httpd配置文件

[root@host conf.d]$httpd -t
Syntax OK
[root@host conf.d]$systemctl reload httpd.service

修改客户端主机的hosts文件，以便能解析域名

hosts在windows环境下的路径为C:\Windows\System32\drivers\etc。在该文件中添加两行

192.168.55.128 www1.stuX.com
192.168.55.128 www2.stuX.com

访问结果

图1、访问www1站点

图2、访问www2站点

图3、查看www1站点的访问状态——正常

图4、查看www2站点的访问状态错误
