How is the apache virtual host configured? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Apache virtual host is to configure multiple virtual hosts on the apache server, so that one server can provide multi-site service implementation. In popular terms, it is to access different directories on the same server.

Apache name-based virtual host settings

In this way, virtual hosts share the same Apache, so when CGI programs are running, the security is not high. When setting up this virtual host, you only need to set information similar to the following for each virtual host, NameVirtualHost 111.222.33.44; receive the service ServerName www.company1.com DocumentRoot/www/ company1 ServerNamewww.company2.comDocumentRoot/www/company2 of the virtual host at this IP address

Advantages: only one IP address can provide a large number of virtual hosting services.

Disadvantages: poor security. The configuration file needs to be changed when maintaining these virtual hosts, and the Apache process needs to be restarted to work. Therefore, it is not suitable for large-scale virtual space services.

Apache virtual host setting based on IP address

The first step is to set a separate IP address for each virtual host on the server. These IP addresses can be accomplished by adding multiple network cards or setting multiple IP addresses on one network card. Once you have multiple IP addresses, you can set up Apache in two ways.

1. Run a copy of Apache for each web space in this way, each Apache program can be run as a separate user, so the virtual hosts do not affect each other. When setting up such a virtual host, you only need to set a set of configuration files for each Apache, and you must use the "Listen" statement to force each Apache to receive service requests only on its own IP address.

Advantages: each virtual host does not interfere with each other and has high security. Disadvantages: take up a lot of system resources.

2. Multiple virtual hosts share the same Apache, so there is a certain influence among virtual hosts, especially when executing CGI programs, it may bring some serious security problems. When setting up this kind of virtual host, you only need to set information similar to the following for each virtual host to DocumentRoot / home/company1.

Advantages: it takes up less system resources than the previous method. Disadvantages: low security, each virtual host still needs to occupy an IP address.

When users have high requirements for security, virtual hosts based on IP addresses can be used, and each virtual host is served by a separate Apache process. In other cases, the virtual hosting service can be set up according to the actual requirements.

After reading the above, have you mastered how to configure the apache virtual host? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
