HTTP installation Configuration _ Learning Notes

Apache:

Ncsa,httpd

A patchy Server = = Apache

Fsf:gnu, GPL

Asf:apache Software Foundation (Apache Software Foundation)

Web:httpd

Tomcat

Hadoop

HTTPD: (1.3, 2.0, 2.2, 2.4)

Web Server,open Source (0.9, 1.0, 1.1 1.1 adds cache capability, supports long connections)

1. Create a process beforehand

2, adaptive on-demand maintenance process (minimum maximum idle process)

3, modular process, the core is small, function by adding modules to implement (including PHP)

4. Support Virtual host configuration in various ways

Single host single Web program, can provide multiple different Web sites

IP-based virtual host

Port-based virtual host

Domain-based virtual host

Supported Features:

HTTPS function (MOD_SSL)

User authentication: Simple authentication, Digest authentication, form authentication

Support for IP-or domain-based ACLs

Support for per-Directory access control

Support for URL rewriting

/USR/SBIN/HTTPD (Mem:prefork)

Httpd:root,root-led process (processes smaller than port 1024 require root boot), responsible for maintaining the worker process

Httpd:apache,apache Work Process

Port: (80/TCP), (SSL 443/tcp)

/ETC/HTTPD Working root directory

/etc/httpd/conf Configuration file Directory

/ETC/HTTPD/CONF/HTTPD.CONF Master configuration file

/etc/httpd/conf.d/*.conf Secondary configuration file

/etc/httpd/modules

/etc/httpd/logs-/VAR/LOG/HTTPSD

Log file: Access log (access_log), error log (Err_log)

/var/www/

HTML static Web page file path

Cgi-bin the path used to provide dynamic content

Cgi:common Gateway Interface (Universal Gateways Interface)

CLIENT-->HTTPD (index.cgi)-->spwan Process (index.cgi)-->httpd--client

FastCGI

Programs: Directives and data

Data: Database Services

HTTPD Service:

Configuration file:

Directive values

Directives are case-insensitive

Values are likely to be differentiated as needed

Professional tools for testing Web services: LoadRunner

Mpm:mutil Path Modules (multi-channel processing module)

Mpm_winnt:windows dedicated (Windows itself supports multithreading)

Prefork: A request is processed with a process

Worker: A request that responds with one thread, initiates multiple processes, starts multiple threads per process, and has a lock mechanism for resource expropriation

Event: A process handles multiple requests, 2.2 does not support such a mechanism, and 2.4 uses this type of request mode by default

Options:

Indexes: Allow index directory

None: No options are supported

FollowSymLinks: Allow access to the file that the symbolic link points to

Includes: Allows execution of server-side containing related documents and scripts

EXECCGI: Running CGI scripts

All: Enable all

Order: Used to define host-based access control

Order Allow,deny

Allow from all

Deny from Deny

For example: Only 192.168.0.1 access is allowed:

Order Allow,deny

Allow from 192.168.0.1

HTTP-T detecting configuration file Syntax format

ELinks Http://host/source/to/path Display text page

-dump exiting interactive mode

-source Display Source code

Set up Web Authentication login:

First, modify the allowoverride value in <directory> to Authconfig

Then configure:

AuthType Basic

AuthName "This is Auth Web ..."

authuserfile/etc/httpd/conf/htpasswd

Authgroupfile/etc/httpd/conf/htgroup

Require Group Mygrp

Require Valid-user

Require User Test

The group file was created manually: Mygrp:test1 test2

Then establish the authentication file, add, delete the user:

htpasswd

-C use when first adding a password file

-M Add user

-D Delete User

Htpasswd-c-m/etc/httpd/conf/htpasswd Test1

Virtual Host:

Apache Services:

Service to multiple different sites

Apache:

Central host

Virtual Host

Based on IP

Ip1:80

Ip2:80

Port-based

Ip:80

ip:8080

Domain-based

Ip:80

Host name is different

Www.test1.com

Www.test2.com

Www.test3.com

To require your host to take effect, you need to note the central host, method: Note DocumentRoot can

Configuration file Contents:

<virtualhost host> Host Definition: Three ways to base your virtual host

ServerName

Serveralias

DocumentRoot "/www/test1/"

<directory "/www/test1" > here is a property definition relative to the file system directory

Options

Allowoverrdie

</Directory>

Alias

Errorlog

Customlog

<location "/first" > here is a property definition for the URL link directory

Defining Request Methods

</Location>

Scriptalias

</VirtualHost>

Dynamic classification:

Client dynamic

Service-Side dynamic
