Detailed explanation of Apache server for Php learning

Php learning server - detailed explanation of Apache server

IisServer: Mainly serving Microsoft, based on basic Internet services running Microsoft windows

LighttpdServer: Open source software, aiming at high performance, low memory overhead, low CPU usage, not mature enough

Introduction to Apache server

1. Packet capture software: httpwatch.rar, learn about sending and receiving data packets

2. Installation of Apache server

1. Check the installed services in windows and make sure apache is not installed originally

2. Install apache server:

3. Whether the test is really successful. Enter http://localhost/ in the browser to display itworks, indicating that the installation is successful

3. Apache server usage and configuration, start and stop, installation and configuration

1. Refer to the Chinese version of the Apache official website reference manual

2. After Apache is successfully installed, windows runs as a service.

3. In most cases, the apahce server is not local, so it is important to learn to use command line remote management to start or stop it.

Httpd –k start[shutdown"restart] [Note] The httpd application is in the directory of the apache installation file. It is necessary to set environment variables.

4. The default port of Apache is 80: http://localhost:80/. In actual development, it is often used

netstat –an

Check which ports the machine is listening on.

Netstat –anb

Discover which program is listening on the port and use the kill command to shut down the process

5. How to configure apache port:

Apache can listen to multiple ports at the same time. Modify the configuration in the httpd.conf file. We modify the port. After the modification is completed, restart the apache server.

Listen on multiple ports:

Apache implements monitoring of multiple ports at the same time.

6. Detailed analysis of apache directory:

The access method to the site is relatively simple. You can directly access it by following the path of the subdirectory in the directory:

Apache manages functions in the form of modules. When Apache starts, it will read the httpd.conf file to load the modules of various .so files in modules.

If you don’t want it to be loaded (do not use its function), you can comment it out directly (add a # sign in front of the comment). [Note] Under normal circumstances, the loaded modules will not be changed...

The core service of Apache is httpd, and then various services are loaded in sequence. Apache is open source and its source code can be read.

7. apache virtual directory

Requirements: Apache is installed on the c drive, and a folder in the d drive is managed as a site.

Set up to achieve:

1. Modify the httpd.conf file and add a virtual directory node:

2. Modify the httpd.conf file and log out of the documentRoot main directory:

After logging out, you will not be able to directly access the default directory website in the apache installation directory.

3. Restarting can be achieved. (If the written content is wrong, apache will fail to restart and report an error!)

(original file address)

Use (direction after virtual directory)

8. Set up apache’s welcome page

Requirement: Enter http://localhost/myblog directly to get the welcome page [Note] myblog is a folder that stores the website, not a file.

Implementation: Modify virtual directory:

(Add a web page after DirectoryIndex, the current directory, as a welcome interface)

9. About the access permissions of apache server

Set access to where the website is hosted:

Order determines the order of permissions, first consider allow (allow from all in the picture), and then deny (if not written in the picture, it is null)

10. Configuration of virtual host in apache

In fact, it is to set the IP address and virtual domain name for your website, start configuring the virtual host, and then borrow the domain name in the local nds domain name resolution to facilitate domain name access in the browser (domain name access, and then access the local dns resolution, find Otherwise, remote domain name resolution)

1. Enable httpd-vhosts.conf

Uncomment the httpd-vhosts.conf file in httpd.conf to indicate startup

2. Add an entry in httpd-vhosts.conf to configure the virtual host

Find the httpd-vhosts.conf file and add a

Modify it like this:

Local DNS resolution file, add, delete or modify this file to facilitate domain name resolution (actually domain name redirection, easy to be attacked by hackers) file path c:\windowssystem32driversetchosts

Remote DNS domain name resolution server address:

Modify the local DNS resolution file and add an entry to redirect the fake www.sohu.com to the local website.

Details the process of accessing the web page (applicable to php, jsp, asp, asp.net)

Timing diagram:

[Note] If the domain name of the public network (non-127.0.0.1) IP is configured on the intranet, the computer will not adapt it and will also point to 127.0.0.1

The virtual host IP address is the same, otherwise the resolution will be 403 error
