Apache

Apache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies.

The Java Servlet and JavaServer Pages specifications are developed under the Java Community Process.

Installation

Apache

The first app we will install is the web server Apache. To get started open your console and type: sudo apt-get install apache2

After you put in your password and accept and a short wait you should have a working installation of Apache. To test it point your web browser to http://localhost

http://www.apache.org/

http://localhost/

Installing Apache Tomcat Server

1. If you do not have Apache Tomcat on your machine, you will first need to download and

unzip Apache Tomcat (this scenario was written using Apache Tomcat version 5.0.28, but other

versions can be substituted). 2. Start the Eclipse WTP workbench.

3. Open Window -> Preferences -> Server -> Installed Runtimes to create a Tomcat installed

runtime. 4. Click on Add... to open the New Server

Runtime dialog, then select your runtime under Apache (Apache Tomcat v5.0 in this example):

Ensure the selected JRE is a full JDK and is of a version that will satisfy Apache Tomcat (this scenario was written using SUN JDK 1.4.2_06). If

necessary, you can click on Installed JREs... to add JDKs to Eclipse.

Click Finish .

Apache Configurations

.

1.AcceptFilter directiveSyntax: AcceptFilter on|off

Default: AcceptFilter on

Context: server config

Status: core

Compatibility: AcceptFilter is available in Apache 1.3.22 and later

AcceptFilter controls a BSD specific filter optimization

3.AccessConfig directiveSyntax: AccessConfig file-path|directory-path|

wildcard-path

Default: AccessConfig conf/access.conf

Context: server config, virtual host

Status: core

Compatibility: The ability to specify a directory, rather than a file name, is only available in Apache 1.3.13 and later. This directive will be eliminated in version 2.0.

This feature can be disabled using: AccessConfig /dev/null

Or, on Win32 servers, AccessConfig nul

Historically, this file only contained <Directory> sections; in fact it can now contain any server directive

allowed in the server config context. However, since Apache version 1.3.4, the default access.conf file which ships with Apache contains only comments.

4.AccessFileName directive

Syntax: AccessFileName filename [filename] ...Default: AccessFileName .htaccessContext: server config, virtual host

Status: coreCompatibility: AccessFileName can accept more

than one filename only in Apache 1.3 and later

For example: AccessFileName .acl

before returning the document /usr/local/web/index.html, the server will

read /.acl, /usr/.acl, /usr/local/.acl and /usr/local/web/.acl for directives, unless they

have been disabled with <Directory />

AllowOverride None </Directory>

The string provided for the AuthName is what will appear in the password dialog provided by most

browsers.

9.AuthDigestRealmSeed directive

Syntax: AuthDigestRealmSeed secret-real-stringContext: directory, .htaccess

This controls the directory to which Apache attempts to switch before dumping core.

17.DefaultType directive

Syntax: DefaultType MIME-type

Default: DefaultType text/plain


Override: FileInfo

Status: core

There will be times when the server is asked to provide a document whose type cannot be determined by its MIME types mappings.

Status: Core.

Compatibility: Available in Apache 1.3 and late

<DirectoryMatch> and </DirectoryMatch> are used to enclose a group of directives which will apply only to the named directory and sub-directories of that directory, the same as <Directory>. However, it takes as an argument a regular expression.

For example:

<DirectoryMatch "^/www/.*/[0-9]{3}">

19.DocumentRoot directive

DocumentRoot directive

Syntax: DocumentRoot directory-path

Default: DocumentRoot /usr/local/apache/htdocs


Status: core

This directive sets the directory from which httpd will serve files.

Unless matched by a directive like Alias, the server appends the path from the requested URL to the document root to make the path to the document.

Example:

DocumentRoot /usr/web

then an access to http://www.my.host.com/index.html refers to /usr/web/index.html.

20.EBCDICConvert

Syntax: EBCDICConvert On|Off[=direction] extension [extension] ...


Status: core

Override: FileInfo

25.IdentityCheck directive

Syntax: IdentityCheck on|off

Default: IdentityCheck off

Context: server config, virtual host, directory

* parameter-name

* !parameter-name

The directives within an IfDefine section are only processed if the test is true. If test is false, everything between the start and end markers is ignored.

The test in the <IfDefine> section directive can be one of two forms:

Access controls are normally effective for all access methods, and this is the usual desired behavior. In the general case, access control directives should not be placed within a <limit> section

30.<LimitExcept> directive

<LimitExcept> directive

Syntax: <LimitExcept method [method] ... > ... </LimitExcept>

Context: any

Status: core

Compatibility: Available in Apache 1.3.5 and later

See the documentation for <Limit> for more details.For example:

<LimitExcept POST GET>

Require valid-user

</LimitExcept>
