__Scripts to copy [Rocks Clusters](http://www.rocksclusters.org) roll isos to a generic (linux) webserver for faster local hosting__ Purpose: Rocks 7.0 frontends require a web server to have rolls "installed" to download. Sometimes distance or other issues indicate that a local copy on an existing (non-Rocks) web-server would be much better. The scripts in this repository help with that. There are four scripts defined in this roll * rollcopy.sh - copy a roll iso contents for web serving * index.cgi - cgi to present roll directory in a standard format * httpdconf.sh (optional) - defines a virtual server httpd configuration file * unpack-guides (optional) - unpacks roll users guides into a web-servable directory __0. Preparation__ * clone this repository `git clone https://github.com/rocksclusters/roll-server.git` * download the roll isos from UCSD. __I. Copy Roll(s) to a web directory__ For this example, will assume the `/var/www/html/rocks/7.0` is the (already created) parent directory into which you want to copy rolls. The `rollcopy.sh` script will create the subdirectory `install/rolls`. to copy the iso file, `CentOS-7.4.1708-0.x86_64.disk1.iso` to the the release directory: ``` # rollcopy.sh CentOS-7.4.1708-0.x86_64.disk1.iso /var/www/html/rocks/7.0 ``` Repeat the above for each roll iso that you want to copy __II. Make certain that the supplied `index.cgi` script gives the directory listing__ ``` # cp index.cgi /var/www/html/rocks/7.0/install/rolls ``` You will probably need to add something like the following in your Apache configuration, so that the directory index is given via the index.cgi ``` # allow all access to the rolls RPMS AddHandler cgi-script .cgi Options FollowSymLinks Indexes ExecCGI DirectoryIndex /rocks/7.0/install/rolls/index.cgi Allow from all ``` (See below for an example of how to test and verify that your index.cgi is being called properly) __III. (Optional) provide a virtual httpd server__ The script `httpdconf.sh` will write to standard output a reasonable stanza for Apache web server configuration. Suppose that you wanted the virtual server to be called `rocks-7.my.org` and have it used the directory above. Then ``` httpdconf.sh rocks-7-0.my.org /var/www/html/rocks/7.0 ``` will generate an httpds conf file. It is your responsibility to place this on the appropriate directory and restart your webserver. __IV. (Optional) unpack the userguides__ You can unpack userguides ``` unpack-guides.sh /var/www/html/rocks/7.0/install/rolls /var/www/html/rocks/7.0 ``` __V. Verifying that your output is correct (that is, index.cgi is being called)__ try ``` wget -O - http://central-7-0-x86-64.rocksclusters.org/install/rolls ``` and compare the output of the rocks central server listing of rolls to your website, something like ``` wget -O - http://rocks-7-0.my.org/install/rolls ``` You should see output very similar to ``` TTP request sent, awaiting response... 200 OK Length: 877 [text/html] Saving to: ‘STDOUT’ 0% [ ] 0 --.-K/s 100%[======================================>] 877 --.-K/s in 0s ``` __VI. Verifying that rolls directories can be listed__ The rolls themselves need be listed. Try the following ``` wget -O - http://central-7-0-x86-64.rocksclusters.org/install/rolls/base/7.0/x86_64 ``` and verify that when you use your roll server instead that you get the same output __VII. Other items to check__ The following may need to be checked/changed for your setup: * Firewall needs modifying on your web server to allow http access (platform sepcific) * SELinux may need to be modified or turned off (e.g., ```setenforce Permissive```)
