CentOS7配置httpd虚拟主机的操作步骤：1、查看CentOS7系统版本和httpd版本；2、输入“systemctl start httpd.service ”命令启动httpd；3、使用curl命令访问虚拟主机；4、借助mkdir命令创建指定文件目录；5、打开vir.conf配置文件，根据要求填写虚拟主机配置信息；6、创建两个web测试页面；7、重载httpd配置文件使修改生效；8、 修改客户端主机的hosts文件，让主机能够解析域名；9、在浏览器中访问web测试页面即可查看结果。
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 -vserver version: apache/2.4.6 (centos)

启动httpd，测试能否正常运行
[root@host ~]$systemctl start httpd.service[root@host ~]$systemctl status httpd.service

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>

创建www1和www2的index页面
[root@host conf.d]$cat /web/vhosts/www1/index.htmlwelcome to www1
thank you
[root@host conf.d]$cat /web/vhosts/www2/index.html
welcome to www2
thank you
重载httpd配置文件
[root@host conf.d]$httpd -tsyntax ok
[root@host conf.d]$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
