##################################################### # pha - Perl High Availability Toolkit # ##################################################### Software to keep scriptable service(s) alive on one of two nodes. In this development example it is an virtual IP and the http service scripted trough the shell scripts in ./res/. folders & files: ./README # pha configuration file ./etc/config # programms ./bin/pha-cli.pl ./bin/pha-supervise.pl ./bin/pha-receiver.pl ./bin/pha-sender.pl # Libary with common functions, used by pha-*.pl ./lib/pha.pm # pids and logs ./var/run/ ./var/log.* # ressource scripts, look into test for an example what they must provide! (start, stop, check) ./res/ ./res/service ./res/ipaddr ./res/test # # set a nice shell prompt status indicator: # # this one would work with bash, place it in your profile, # may be .bashrc, .profile or .bash_profile # # or even global in /etc/bashrc or /etc/profile # getPromptStatus() { ls /opt/pha/var/run/{receiver,sender,supervise} >/dev/null 2>&1 if [ $? != 0 ]; then status='NOTRUNNING' else if [ "$(/opt/pha/bin/getst.pl 2>/dev/null)" == "ONLINE" ]; then status='Active' else status='Standby' fi fi echo $status } # the PS1 is to set somewhere in bashrc or profile, some examples: # debian # PS1="${debian_chroot:+($debian_chroot)}\u@\h:[\$(getPromptStatus)] \w\$ " # RHEL 5 like # PS1="[\u@\h:\$(getPromptStatus)] \W \\$ "
