The Apache HTTP Server ('httpd') was launched in 1995 and it has been the most popular web server on the Internet since April 1996. It has celebrated its 25th birthday as a project in February 2020. The Apache HTTP Server is a project of The Apache Software Foundation. Apache httpd 2.4.46 Released 2020-08-07 ¶. Apache is not a web browser (client), it's a web server. Subject to other pre-requisites (e.g. PHP installed), Apache is used to host a web site. If Apache says that it's running, then it's running. Please clarify what you are trying to do? First go to in configure httpd.conf folder in apache and open change the port value 80 instead of 8080 ( two place u need to check in code ). Then go to services (click ur start button and type this in ' search programs and file ') and then search for 'Web Deployment Agent Service'and stop it. Then go and restart ur apache. Then ur local host will start work.
Apache logs can be analyzed through a Web browser using free scripts, such as AWStats/W3Perl or Visitors. Virtual hosting allows one Apache installation to serve many different websites. For example, one computer with one Apache installation could simultaneously serve example.com, example.org, test47.test-server.example.edu, etc.
The Apache HTTP Server Project is an effort to develop and maintain anopen-source HTTP server for modern operating systems including UNIX andWindows. The goal of this project is to provide a secure, efficient andextensible server that provides HTTP services in sync with the current HTTPstandards.

Apache Is Most Popular Web Browser
The Apache Software Foundation and the Apache HTTP Server Project arepleased toannounce therelease of version 2.4.46 of the Apache HTTP Server ('httpd').
This latest release from the 2.4.x stable branch represents the best availableversion of Apache HTTP Server.
Apache HTTP Server version 2.4.43 or newer is required in order to operate a TLS 1.3 web server with OpenSSL 1.1.1.

As previously announced, the Apache HTTP Server Project has discontinuedall development and patch review of the 2.2.x series of releases.
The Apache HTTP Server Project had long committed to provide maintenancereleases of the 2.2.x flavor through June of 2017. The final release 2.2.34was published in July 2017, and no further evaluation of bug reports orsecurity risks will be considered or published for 2.2.x releases.
Great! We have updated our download page in an effort tobetter utilize our mirrors. We hope that by making it easier to use our mirrors, we will be able to provide a better download experience.

Awesome! Have a look at our current 'Help Wanted' listings then:

What Is the Hive Web Interface
The Hive Web Interface is an alternative to using the Hive command line interface. Using the web interface is a great way to get started with Hive.
The Hive Web Interface, abbreviated as HWI, is a simple graphical user interface (GUI).
Version
HWI is only available in Hive releases prior to 2.2.0. It was removed by HIVE-15622.
WebHCat API
Another web interface that can be used for Hive commands is WebHCat, a REST API (not a GUI). With WebHCat, applications can make HTTP requests to access the Hive metastore (HCatalog DDL) or to create and queue Hive queries and commands, Pig jobs, and MapReduce or YARN jobs (either standard or streaming). WebHCat was formerly named Templeton. See these documents for more information:
- Using WebHCat in the WebHCat manual
- Using HCatalog in the HCatalog manual
Features of HWI
Schema Browsing
An alternative to running 'show tables' or 'show extended tables' from the CLI is to use the web-based schema browser. The Hive metadata is presented in a hierarchical manner allowing you to start at the database level and click to get information about tables including the SerDe, column names, and column types.

Detached Query Execution
A power user issuing multiple Hive queries simultaneously would have multiple CLI windows open. The Hive Web Interface manages the session on the web server, not from inside the CLI window. This allows a user to start multiple queries and return to the web interface later to check the status.
No Local Installation
Any user with a web browser can work with Hive. This has the usual web interface benefits. In particular, a user wishing to interact with Hadoop or Hive requires access to many ports. A remote or VPN user would only require access to the Hive Web Interface running by default on 0.0.0.0 tcp/9999.
Configuration
Hive Web Interface made its first appearance in the 0.2 branch. If you have Hive release 0.2 or later, or the SVN trunk, then you already have it.
You should not need to edit the defaults for the Hive Web Interface. HWI uses:
You probably want to set up HiveDerbyServerMode to allow multiple sessions at the same time.
Start Up
When initializing
Jetty requires Apache Ant to start HWI. You should define ANT_LIB as an environment variable or add that to the
hive
with no arguments, the CLI is invoked. Hive has an extension architecture used to start other hive
demons.Jetty requires Apache Ant to start HWI. You should define ANT_LIB as an environment variable or add that to the
hive
invocation.Java has no direct way of demonizing. In a production environment you should create a wrapper script.
If you want help on the service invocation or list of parameters you can add
Authentication
Hadoop currently uses environmental properties to determine user name and group vector. Thus Hive and Hive Web Interface cannot enforce more stringent security then Hadoop can. When you first connect to the Hive Web Interface you are prompted for a user name and groups. This feature was added to support installations using different schedulers.
If you want to tighten up security you are going to need to patch the source Hive Session Manager or you may be able to tweak the JSP to accomplish this.
Accessing HWI
In order to access the Hive Web Interface, go to <Hive Server Address>:9999/hwi on your web browser.
Tips and Tricks
Result File
The result file is local to the web server. A query that produces massive output should set the result file to /dev/null.
Debug Mode
Debug mode is used when the user is interested in having the result file contain not only the result of the Hive query but also the other messages.
Set Processor
In the CLI a command like 'SET x=5' is not processed by the the Query Processor, it is processed by
the Set Processor. Use the form 'x=5', not 'set x=5'.
