What is apache2?

The Apache2 Software Foundation (ASF) is a non-profit organization that provides Supported by open source software projects from the Apache community.

There are now three versions of Apache HTTP, 1.3 2.0 and 2.2

In its 1.X version era, although Apache has been stable and powerful enough and achieved a pivotal position, it still exists Some non-full-featured WEB servers have gained market share in areas that it cannot cover.

This situation has been greatly improved in 2.X, and compilation and installation have become simpler. Apache uses the standard GNU automatic configuration tool. For Windows platforms, it also provides graphical installation interface.

In terms of settings, the new version has removed some confusing instructions, but most of the work is still based on a file settings file. It may be a bit troublesome for users who are used to graphical interface configuration tools.

The setting tools are separated from the core release package. Some such as ApacheConf can be obtained for free or at a very low price. These tools can be used to easily perform various settings on Apache.

From an operational perspective, the Apache2.X version is more powerful and more scalable than the old version.

A hybrid multi-thread/multi-process module allows it to fully exploit the performance of hosts of all sizes (from a typical X86 server running only a small site to a large host running multiple virtual instances simultaneously), This is exactly what Apache1.3 lacks. The new version provides support for some specific platforms and several general modules in the form of plug-ins. Official support for IPV6 is ready for Internet upgrades, and support for HTTP 1.1 improves proxy server performance.

In addition, the new version of the core release package adds several modules to enhance security and manageability:

mod_auth_ldap introduces authentication based on LDAP (Lightweight Directory Access Protocol), and the mod_autoindex module can be easily Conveniently generate directory listings for visitors, and the mod_deflate module allows content to be compressed before sending to save bandwidth.
