How-to install and configure the Boa Web server on your Armadeus board

Boa.png


Installation

  • Launch Buildroot's configuration:
 $ make menuconfig
  • Select: 
...
Package Selection for the target  --->
    [*]   Show packages that are also provided by busybox
        ...
    [*] Networking  --->
            ...
        [*]   boa
  • Save the configuration
  • Then build the binaries and the default filesystem. This will be useful later to perform the configuration:
 $ make

Configuration

Generalities

To apply a permanent configuration, be sure not to change anything on the board filesystem: that would be erased the next time you reflash the rootfs.
Instead, do all changes on the filesystem located on the Host, i.e. on buildroot/project_build_armv4t/apf9328/root/ for the APF9328 or buildroot/project_build_armv5te/apf27/root/ for the APF27.

The Boa configuration file is located in /etc/boa/boa.conf on the board; this means that to permanently change the configuration, you need to edit the file buildroot/project_build_armvXX/apfXX/root/etc/boa/boa.conf on the Host.

As the root directory name is dependent of the target, there is a way to find it automatically: 

$ make shell_env && source armadeus_env.sh

Then the directory can be accessed with $ARMADEUS_ROOTFS_DIR.

Create a Dummy page

  • By default, DocumentRoot is set to /var/www, so let's add a dummy file here to test our configuration:
$ mkdir $ARMADEUS_ROOTFS_DIR/var/www
$ vim $ARMADEUS_ROOTFS_DIR/var/www/index.html
  • And fill the file with:
<html>
    <head>
        <title> Welcome on the Armadeus Board </title>
    </head>
    <body>
        <nowiki><h1> Welcome on the Armadeus Board </h1></nowiki>
    </body>
</html>

Enable hostname resolution

  • Boa has to be able to resolve the hostname to work, so let's do:
$ echo "127.0.0.1 `cat $ARMADEUS_ROOTFS_DIR/etc/hostname`" >> $ARMADEUS_ROOTFS_DIR/etc/hosts

Create the access log directory

  • By default, Boa logs will be stored in /var/log/boa/. If you didn't not change this setting, you will need to perform the following :
$ ls -l $ARMADEUS_ROOTFS_DIR/var/log
  • If it's a link to /tmp, then 
$ rm -f $ARMADEUS_ROOTFS_DIR/var/log && mkdir $ARMADEUS_ROOTFS_DIR/var/log/
  • Then, create the boa directory :
$ mkdir $ARMADEUS_ROOTFS_DIR/var/log/boa

Why shoud I delete the symbolink link?
This is because during the filesystem creation, mkfs.jffs2 will keep the link from /var/log to /tmp on the board. Thus, once on the board, you will have: 

 # ls -l /var/log
 lrwxrwxrwx    1 root     root            4 Apr 15  2007 /var/log -> /tmp

With such a behavior, even if you fill the directory $ARMADEUS_ROOTFS_DIR/var/log/ on your host (which actually fill /tmp on your host), nothing will be saved once the filesystem will be flashed on your board.

Test the result

  • Create the final rootfs:
$ make

 # boa
  • To access your web page, use a browser:
http://<your board's IP Address>/

You should see the page !
If not, check the file /var/log/boa/error_log on your board

Boa welcome.png

Working with cgi

  • First, check the boa.conf file. Once more, you should use the one located on your host before changing anything.
$ vi $ARMADEUS_ROOTFS_DIR/etc/boa/boa.conf
  • Be sure to have an uncommented line like this:
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
  • Now, let's write a dummy cgi:
$ mkdir $ARMADEUS_ROOTFS_DIR/usr/lib/cgi-bin
$ vim $ARMADEUS_ROOTFS_DIR/usr/lib/cgi-bin/get_ipconfig.sh
  • And add the following :
#!/bin/sh
echo -e "Content-type: text/html\r\n\r\n";
echo -e `/sbin/ifconfig  eth0 | grep 'inet addr'`;

The script have to be executable: 

$ chmod a+x $ARMADEUS_ROOTFS_DIR/usr/lib/cgi-bin/get_ipconfig.sh
  • Then change your index.html page to add a link to the cgi:
$ vi $ARMADEUS_ROOTFS_DIR/var/www/index.html

<html>
    <head>
        <title> Welcome on the Armadeus Board </title>
    </head>
    <body>
        <h1> Welcome on the Armadeus Board </h1>
        <br> <br>
        <a href=http://<Your board IP Address>/cgi-bin/get_ipconfig.sh> Get the board ip config </a>
        <br>
    </body>
</html>
  • Create the new rootfs:
$ make

You can now access to the new web page and click on the cgi link !
