Apache2 has growing demand among Linux Hosting consumers. For installing Apache2 you need to enter the following command at a terminal prompt.
sudo apt-get install apache2
Further more you need to place directives in plain text configuration files, these directives are separated between the following shown files and directories
- apache2.conf: This is the main Apache2 configuration file. Contains settings that are global to Apache2.
- conf.d: This contains configuration files which are applicable globally to Apache2 and some other packages which can be used by Apache2 for addition or symlinking files to this directory.
- envvars: Apache2 environment variable are set in this file.
- httpd.conf: Named after the httpd daemon, this was the Apache2 configuration file, it can be used for particular configuration option which globally affects Apache2.
- mods-available: Not only for loading modules but also for their configuration, this file can be utilized. (Only few specific and not all of the modules are included it this file)
- mods-enabled: This file has the ability to hold symlinks of files situated at /etc/apache2/mods-available, and this makes it possible to enable the symlinked file enabled at the next time Apache2 is restarted.
- ports.conf: Herea are the directives which analyze, which TCP ports Apache2 is listening currently.
- sites-available: Configuration files for Apache2 Virtual Hosts can be found in this directory. These virtual hosts permit Apache2 to get configured for more than one website which have their own separate configuration settings.
- Sites-enabled: similar to ‘mods-enabled’ here one can find symlinks at /etc/apache2/sites-available directory, also when a particular configuration file in ‘sites-enabled is found symlinked, the website configured by it can be kept active when the Apache2 is restarted.
As Security is one of the most important concerns in the internet world for webmasters, they should always keep their security system arrangements up to the mark, because hackers are always searching for new possible techniques to control your website and misuse it for their motive. Security measures can be classified in many categories, but a securing a website should cover security of web application as well as security of the web hosting server on which the web applications and website are hosted. Here I would like the share the information over security options on a LAMP (Linux, Apache, MySQL and PHP) as it is the most widely found combination among Linux Hosting Servers.
Instances in which a Web Hosting Server responds to the web browsers which are used by the visitors of the particular website residing on that particular website, that server provides a particular ‘header information’. Apache web servers are known for publishing many details of its environment as well as sometimes PHP also can be found responding in such header parts. Hackers may take advantage of this exposure in such headers of you website. Furthermore if he succeeds in knowing the factors like the type of web hosting services, type of server used, the web hosting platform, the version of scripting engine and other applications then it becomes an easy task for hackers to trace specific bugs or security loopholes. This makes the task easy for hackers to achieve their motives.
But still one can configure both Apache and PHP in such a way that it will remain hidden and will keep the possible attackers in the dark.
Apache Servers are one of the most important web server softwares of Linux hosting services and generally it has no demands from the webmasters opting for Windows Web Hosting services. A patch can be defined as a small application or a program of software designed for fixing the existing problems or drawbacks with it’s current version. This fixing can be in terms of vulnerabilities, bugs, inabilities and uncompetitiveness compared to other similar competing softwares. In short the patch is the difference between the previous version and upgraded version of a software. Similarly Apache patches are designed to improve the performance of Apache within different areas. Official Patches released by Apache can be treated as upgraded versions of Apache. If one has the Apache source product installed then the patches will be installed or updated automatically, otherwise the files will be there in the actual patch and one can find them under any of the ‘reloc’ directories. Being an open source a person can develop a patch as per his requirements and can also share it with others. But though the patches are developed with the purpose of fixing problems and bugs, a wrongly developed patch can affect inversely with the performance of Apache. Few of the developers also have provided the patch management softwares in the market to manage the patches with the ease. Even few of such softwares can update multiple computers at the same time withing multiple networks.
The range of these patches is very wide and one can choose from the basic home editions to ones which can mange high number of commercial computers networks. The choice is available according to the webmaster’s needs to make their web hosting services more suitable for their website.. Patches related to improvising security features are supposed to be most popular patches among webmasters.
