实验：httpd

虚拟主机

httpd-2.4示例步骤：

1. 进行规划虚拟主机
192.168.209.8:80,192.168.209.10:80
www.10linux.com,www.iounix.com
/var/www/html/10linux,/var/www/html/iounix

2.
]# mkdir /var/www/html/{10linux,iounix}
~]# vim /var/www/html/iounix/index.html
    <h1>iounix.com</h1>
~]# vim /var/www/html/10linux/index.html
    <h1>10linux.com</h1>
    <h2>welcome here</h2>

3. 编辑配置文件
/etc/httpd/conf.d/10linux.conf
<VirtualHost 192.168.209.8:80>
        ServerName www.10linux.com
        DocumentRoot "/var/www/html/10linux"
        <Directory "/var/www/html/10linux">
                Options None
                AllowOverride None
                Require all granted
        </Directory>
        CustomLog "logs/10linux_access_log"
</VirtualHost>

/etc/httpd/conf.d/iounix.conf
<VirtualHost 192.168.209.10:80>
        ServerName www.iounix.com
        DocumentRoot "/var/www/html/iounix"
        <Directory "/var/www/html/iounix">
                Options None
                AllowOverride None
                Require all granted
        </Directory>
        CustomLog "logs/iounix_access_log" combined
</VirtualHost>

4.
httpd -t
systemctl restart httpd.service

5. 验证：不同IP，相同端口
    ip addr add 192.168.209.10/24 dev eth0
6. 验证：相同IP，不同端口
    需在配置文件中添加Listen 10080,修改IP地址; 使IP相同，port不同
    ip addr del 192.168.209.10/24 dev eth0

7. 验证：相同IP，相同端口，不同主机名
    可搭建DNS解析验证

问题：重启httpd服务Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

httpd内建的状态页面

httpd-2.4示例：

1
vim /etc/httpd/conf.d/10linux.conf
<VirtualHost 192.168.209.8:80>
        ServerName www.10linux.com
        DocumentRoot "/var/www/html/10linux"
        <Directory "/var/www/html/10linux">
                Options None
                AllowOverride None
                Require all granted
        </Directory>
        CustomLog "logs/10linux_access_log"
        <Location /server-status>
            SetHandler server-status
            <RequireAll>
                Require ip 172.16
            </RequireAll>
        </Location>    
</VirtualHost>

如要做认证：
<Location /server-status>
    SetHandler server-status
    AuthType ...
    ...
