Installing lamp and webmin on raspbian

Another writeup on installing a lamp server setup on a Raspberry Pi.  Probably need a 3 or 3+ to have any real justification, YMMV

sudo groupadd -f -g33 www-data
sudo apt-get update
sudo apt-get install apache2 php5 libapache2-mod-php5
sudo apt-get install mysql-server mysql-client php5-mysql
sudo apt-get  install  phpmyadmin
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl \

libpam-runtime libio-pty-perl apt-show-versions python 

webmin:

mkdir webmin
cd webmin
wget http://prdownloads.sourceforge.net/webadmin/webmin-1.580.tar.gz
gunzip webmin-1.580.tar.gz
tar xf webmin-1.580.tar
cd webmin-1.580
sudo ./setup.sh /usr/local/webmin

This discusses after the fact addition of SSL to webmin.  Installation and support may already be present.

Secure Connection Failed when accessing webmin

Webmin may have 1024 SSL certificates.

SSL_ERROR_WEAK_SERVER_CERT_KEY

Upgrade Webmin certificate to 2048 bit

You can replace your webmin certificate with a new one by running this command:

file=/etc/webmin/miniserv.pem
openssl req -x509 -newkey rsa:2048 -keyout $file  -out $file \
 -days 3650 -nodes -subj \
 "/C=US/ST=Denial/L=Springfield/O=Dis/CN=www.example.com" 
openssl x509 -x509toreq -in $file -signkey $file >> $file
/etc/init.d/webmin restart

This command will create a 'pem' file with both the private key and self-signed certificate in the same file.  -nodes will let you create the file without a passphrase.  The -subj option saves you having to manually enter certificate details.
