 Creating your own websites can be fun and SDF gives webspace to all its validated users, so the moment you become validated you can begin creating your own websites straight away. Creating your own websites can be fun and SDF gives webspace to all its validated users, so the moment you become validated you can begin creating your own websites straight away.

-''mkhomepg'' - This command needs to be executed before you can start building your web pages. When you execute this program, it will create a directory in which you can put all your web files. This directory is sym-linked into your home directory, under the name //html//. (A sym-link is sort of like a shortcut in Microsoft Windows.)You will be prompted to select a URL for your website. This URL is what other internet users type into their web browser to view your web pages. If you're not an ARPA member then you may only use url's in the form of '"<your login>.freeshell.org"'. For instance, my web pages are stored at '"alterego.freeshell.org"'. If you're an ARPA member, there are many different domains you may use.+''mkhomepg'' - This command needs to be executed before you can start building your web pages.

 +==== More Pages ==== 
 +Okay, now that you have your first web page up, here are some [[resources_for_website_builders|Resources for Developing Your Website]] 
 + 
 +An important thing: your website files need to be set to particular user permissions in order to be viewable by the world. When you add pages or subdirectories to your web site, the easiest way to make sure it will all continue to work is to **remember, after you are done with your changes**, to run the command <code> 
 + mkhomepg -p 
 +</code> 
 + The ''-p'' flag sets appropriate permissions for your //~/html//, //~/public_html/// directories on the cluster, including your VHOSTS, as well as your //~/html/<username>// directory on the [[metaarray|The MetaArray]]. 
 + 
 + 
 + 
 +Here are all the options for the mkhomepg command, which you can see by running it with the ''h'' flag: 
 + 
 +<code> $ mkhomepg -h 
 +usage:  mkhomepg            (initial setup) 
 +        mkhomepg -p         (set appropriate file permissions) 
 +        mkhomepg -a         (set or unset your custom URL) 
 +        mkhomepg -d         (set or unset http://sdf.org/~username) 
 +        mkhomepg -t         (toggles SDF cluster/MetaArray hosting) 
 + 
 +</code> 
 + 
 +===== Web Page Locations ===== 
 + 
 +As you can see above with the ''mkhomepg'' command, there are several places your web page files can be: 
 +  * **Standard Site:** By default, your web site files go in your user folder on the cluster in the ''html'' subfolder. These files are then viewable  at //<your login>.freeshell.org//, or what other domain you set as a custom url with mkhomepg or from the ''maint'' command 
 +  * **'Tilde' Site:** You may, if you first run ''mkhomepg -d'' also (or instead) place files in your ''public_html'' folder, and they will be accessible at your old school "tilde site" at //sdf.org/~<your login>// 
 +  * **Virtual Host:** If you have a [[vhost]], you should place files for it in your //<nowiki>/html/vhost_name</nowiki>// folder, and they will appear from your properly configured VHOST, if you have signed up for this [[membership_levels|membership]] 
 +  * **[[metaarray|The MetaArray]]:** If you want to host from the unlimited storage of the MetaArray, after you use ''mkhomepg -t'' to toggle your main web page from the cluster to the MetaArray, you should put your files on the metaarray at //~/html/<username>//, and as with the cluster, these will be accessible at //<your login>.freeshell.org//, or what other domain you set as a custom url with mkhomepg or from the ''maint'' command
  
 ===== Problems ===== ===== Problems =====
  
-The most important thing you need to have is **patience**. Sometimes updates when running "mkhomepg" may take a few hours to complete, sometimes they will occur almost immediately. By using the higher functions of your brain and **patience** you will solve a lot of the problems you may meet!+The most important thing you need to have is **patience**.

 In case a page is not found on your site, the client may be forwarded to a page of sdf.org or redmartian, which can be confusing (but which is in fact completely reasonable, as all the domains belong to one entity). If you want to prevent this also for broken links, you have to set up error handler documents. Please consult the FAQ, [[https://sdf.org/?faq?WEB?07|"CAN I DEFINE MY OWN 403, 404 and 405 ERRORDOCUMENTS?"]] item for this! In case a page is not found on your site, the client may be forwarded to a page of sdf.org or redmartian, which can be confusing (but which is in fact completely reasonable, as all the domains belong to one entity).

-===== Diagnose =====+==== Diagnose ====
  
-If your site is hosted on sdf.org (you are an ARPA member) then you can grep inside the httpd log file in ///var/log//directory. For example:+One way to try to figure out what is going wrong when you HTTP requests are made to your site is to look at http access logs. 
 + 
 +=== Finding Your Logs on the Main Cluster === 
 + 
 +If your site is hosted on sdf.org (you are an ARPA member) then you can grep inside the httpd log file in ///var/log// directory. For example:
  
   $ grep abc123.sdf.org /var/log/httpd/*.log   $ grep abc123.sdf.org /var/log/httpd/*.log
 +  
 +=== Finding Your Logs on the Metaarray ===
  
-If your site is hosted on ma.sdf.org (you are a MetaARPA member) then your can look inside the log file for your web site in "/meta/log". For example:+If your site is hosted on ma.sdf.org (you are a MetaARPA member) then you can look inside the log file for your web site in ///meta/log//. For example:
  
   $ less /meta/log/abc123.sdf.org   $ less /meta/log/abc123.sdf.org
 +
 +=== Finding Your Logs for VHOSTs ===
 +If your site is VHOSTed, then you can access your site's own log file by ssh-ing to the ''norge'' server using your {LOGNAME}@{VHOSTDOMAIN} with your normal LOGNAME password, then your log files are ///var/log/nginx/{VHOSTDOMAIN}// and ///var/log/nginx/{VHOSTDOMAIN}.err//. ex: 
 +  $ ssh peteyboy@irulecomputers.com
 +  ... (login stuff)
 +  $ less /var/log/nginx/irulecomputers.com
 +  
 +==== Web Server Details ====
 +Problems you may be having may relate to what web server your pages are running on. That depends, as above, on where you are storing the pages:
 +
 +^Host      ^Web Server Software    ^Web sites hosted^
 +| sdf     | Apache                |user sites |
 +| faeroes | Apache                |ARPA user sites|
 +| iceland | Apache                |MetaARPA user sites|
 +| norge   | nginx                 |VHOST sites|
 +| mab     | nginx                 |MetaArray IVB (MetaARPA)|
