如何在同一端口号上配置两个不同的 Apache 实例，并在单个服务器上使用不同的 IP

Question

Is it possible to configure two different Apache instances on the same port number with different IPs on a single server? Both ports are configured for the same server. httpd.conf of First Apache-

<VirtualHost 10.100.30.50:80>
    DocumentRoot "/www/example-80/pqr"
    ServerName www.example.org
</VirtualHost>

Below configuration is not allowing to start the second Apache instance. httpd2.conf of second Apache-

<VirtualHost 10.100.30.40:80>
    DocumentRoot "/www/example-80/xyz"
    ServerName www.example.org
</VirtualHost>

Second instance is coming up with different IP apart from port 80. Like- 10.100.30.40:8081

getting this error while trying to start second apache

Answer 1

It looks like you have not configured the second IP in any interface on the server. Please configure the IP as virtual interface on the server and try to start apache.
