ASLO Node

While discussing activities.sugarlabs.org maintainability with Dogi this afternoon, he suggested that instead of thinking about web, proxy, and database nodes we create a standard ALSO node which we can adopt and tune via configs.

Components

Install Emacs

I just like it:) 

apt-get install emacs

Setup Network

Set the IP address for the each nic 

emacs /etc/networks/interfaces

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 10.0.0.101
        netmask 255.255.255.0
        network 10.0.0.0
        broadcast 10.0.0.255
        gateway 10.0.0.1

#auto eth1
iface eth1 inet static
        address 10.0.0.201
        netmask 255.255.255.0
        network 10.0.0.0
        broadcast 10.0.0.255
        gateway 10.0.0.1

restart the network 

sudo /etc/init.d/networking restart

Install Database

Install needed packages

apt-get install mysql-client-5.0 mysql-server-5.0

Log Rotate

/etc/logrotate.d/mysql-server 

# - I put everything in one block and added sharedscripts, so that mysql gets  
#   flush-logs'd only once. 
#   Else the binary logs would automatically increase by n times every day. 
# - The error log is obsolete, messages go to syslog now. 
/var/log/mysql.log /var/log/mysql/mysql.log /var/log/mysql/mysql-slow.log { 
        daily 
        rotate 7 
        missingok 
        create 640 mysql adm 
        compress 
        sharedscripts 
        postrotate 
                test -x /usr/bin/mysqladmin || exit 0 
 
                # If this fails, check debian.conf!  
                MYADMIN="/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf" 
                if [ -z "`$MYADMIN ping 2>/dev/null`" ]; then 
                  # Really no mysqld or rather a missing debian-sys-maint user? 
                  # If this occurs and is not a error please report a bug. 
                  if ps cax | grep -q mysqld; then 
                    exit 1 
                  fi  
                else 
                  $MYADMIN flush-logs 
                fi 
        endscript 
}

Turn off database by default

sudo update-rc.d -f mysql remove
