3 Introduction to Apache Apache is a web server package that works under Linux as well as under other operating systems The name Apache comes from the concept of extensive patching of existing code The primary advantage of Apache is that it is generally free or available at modest costs

4 Installing Apache

5 Installing Apache From a CD-ROM If your CD-ROM has Apache and you want to use RPM to install the package, issue this command –rpm –i apache_1_3_4.rpm (substitute the full name of the Apache package)

6 Installing Apache From a Download Place the downloaded files in a location that will be dedicated to the Apache files, such as /usr/apache Uncompress the files using either gzip or tar and compress You must edit the configuration file –You can find more information about this in the Readme file

7 Installing Apache… (con’t) Uncomment all the Modules in the configuration file except –cern_meta_module –msql_auth_module –dld_module Choose either db_auth_module or dbm_auth_module ; they should not be used together

8 Installing Apache… (con’t) Create the configuration file for Linux by issuing the command –Configure Compile Apache by issuing the make command –The most common error message encountered concerns the socket.h library, most likely because TCP/IP is not installed

9 Installing Apache… (con’t) The result of the compilation will be a binary file called httpd Copy this file into /bin or /usr/bin, where it will reside in the path

10 Setting Up the Website

11 Create the home directory for the website, we will use /usr/www/ganesan Create 3 subdirectories under the site directory –conf –htdocs –logs

12 Setting Up the Website (con’t) You will find a subdirectory called conf under the directory where you installed Apache –Copy 3 files ( srm.conf-didst, access.conf-dist, http.conf- dist ) from this directory into /usr/www/ganesan/conf –If you cannot find the 3 files, use the find command to find them

13 Setting Up the Website (con’t) Rename the 3 files you just copied to drop the “-dist ” portion of the name Edit the httpd.conf file to specify –the port number on which your web server responds –the user running the httpd daemon, etc… Specify the server name –ServerName ganesan.com

14 Setting Up the Website (con’t) Add a line that specifies the root directory for your website –DocumentRoot /usr/www/ganesan/htdocs Edit the srm.conf file to set up the web home directory and any special internal command usage Edit the access.conf file to set a basic set of access permissions

15 Setting Up the Website (con’t) In the htdocs directory create an HTML file for the server to read when it starts –This can be any HTML file –The filename should be default.html Start the httpd daemon –httpd –f /usr/www/ganesan/conf

16 Setting Up the Website (con’t) Test the web server by starting a browser and specify the URL http://127.0.0.1/ http://127.0.0.1/ If the system is working properly, you will see a screen with a list of files in the htdocs directory

17 Server Configuration

18 Make sure the ServerType directive is set to “ standalone ” Check the Port device to make sure it is set to the TCP/IP port to which your Apache server listens Set the User directive to either the user ID (UID) or the user name used for all web visitors

19 Server Configuration (con’t) Set the Group directive to either the group ID (GID) or the group name assigned to all web users Modify the ServerAdmin directive to include the e-mail address of the administrator Set the ServerRoot directive to the absolute path to the directory where all Apache resource and configuration files are stored –/usr/apache/conf or /etc/httpd

20 Server Configuration (con’t) Set the ServerName directive to the fully qualified domain name of your server

21 Starting and Stopping Apache

22 If you are running Apache as a standalone server, you need to start and stop Apache manually –Start with httpd –d rootdir –f configs –To stop Apache use ps to detect the httpd daemon’s PID and use the kill command to terminate the process

23 A Note on Starting and Stopping Apache Later versions of Apache include a script that does the start and stop tasks for you

24 Virtual Hosting

25 Virtual Hosts A virtual host is a web server that resides on one domain but acts as if it was on another. For example, suppose you control ganesan.com and cis454.com. Instead of setting up 2 servers, you can set up a single machine that serves both domains. Virtual hosting saves on machinery and allows for a lot of flexibility in setting up web servers

26 Setting Up Virtual Hosting If your network uses a name server for DNS, modify it so that the domain name points to your web server for each domain you’ll host Use the ifconfig command to set up the IP address for each domain on your server –ifconfig eth0:1 xxx.xxx.xxx.xxx

27 Setting Up Virtual Hosting (con’t) Add the route to the network configuration using the route command –route add –host xxx.xxx.xxx.xxx dev eth0:1 Edit the Apache httpd.conf file to set up virtual hosting – DocumentRoot /usr/www/cis454/htdocs TransferLog /usr/www/cis454/logs/access ErrorLog /usr/www/cis454/logs/errors

28 Setting Up Virtual Hosting (con’t) The previous step defines the virtual host for cis454.com and specifies its DocumentRoot, since each virtual host will have different web directories If more than one virtual host is defined, the entries are to be repeated for each

29 A Final Note There are many more configuration options possible with Apache, but they are usually used for commercial sites that require authentication or special handling characteristics

30 Key Terms Apache conf Server Name Virtual Hosting ifconfig
