App Start on Boot
- Install Script:
/usr/bin/crontab -l > apache-crontab; cat >> apache-crontab << 'EOF' @reboot /var/hda/web-apps/appname/html/startup.sh EOF /usr/bin/crontab apache-crontab; rm -rf apache-crontab;
- Uninstall Script:
/usr/bin/crontab -l > apache-crontab; sed -i '/appname/d' apache-crontab; /usr/bin/crontab apache-crontab; rm -rf apache-crontab;
Find and Rename .htaccess Files:

Add Server (Service) Feature
- Install Script:
cat > installscript.sh << 'EOF' install -m 755 appname /etc/init.d/; /sbin/chkconfig appname on; /sbin/service appname start; EOF chmod 755 installscript.sh; sudo ./installscript.sh; cd ..; rm -rf elevated;
- Uninstall Script:
mkdir elevated; cd elevated; cat > uninstallscript.sh << 'EOF' /sbin/service appname stop; /sbin/chkconfig appname off; rm -f /etc/init.d/appname; EOF chmod 755 uninstallscript.sh; sudo ./uninstallscript.sh; cd ..; rm -rf elevated;
- Example Init Scripts (services)
- Change service run level, start, and stop priority:
Edit the service, i.e. /etc/init.d/adito and change the parameters (Run level: 0-6, start priority: 1-99, and stop priority: 1-99).
# chkconfig: 2345 56 26
Execute the following command as root user:
/sbin/chkconfig adito resetpriorities
Custom Webapp Options

RewriteEngine On RewriteCond %{SERVER_PORT} 80 RewriteRule ^(.*)$ https://webmin.olympus.com:10000/$1 [R,L]

- Arch (32- or 64-bit):
export MACHINE_TYPE=`uname -m`; echo $MACHINE_TYPE > arch.txt; if [ ${MACHINE_TYPE} == 'x86_64' ]; then # 64-bit else # 32-bit fi
- HDA IP Address:
export HDAIP=`ifconfig eth0 | grep "inet addr" | awk '{ print $2 }' | awk 'BEGIN { FS=":" } { print $2 }'`;
- First Admin User:
export FUSER=`/var/hda/platform/html/script/first-admin`
