Auto-Run Script Upon System Boot Up
From PicOS2.9.1, user can add customized scripts which will run automatically upon system boot up.
The script at /cftmp/auto/pre-nos will be started when Linux booting is over. The script at /cftmp/auto/post-xorplus will be launched when XorPlus is ready. And the script at /cftmp/auto/post-ovs will be launched when OVS is ready.
The files pre-nos/ post-xorplus/ post-ovs are not existing in directory /cftmp/auto defaultly. If user want to run the scripts, they need to create them and make sure they are read and write files.
Example 1:
Run script when Linux booting over.
admin@PicOS-OVS$sudo touch /cftmp/auto/pre-nos admin@PicOS-OVS$sudo chmod 777 /cftmp/auto/pre-nos admin@PicOS-OVS$sudo vi /cftmp/auto/pre-nos echo "####################Start add linux scripts####################" echo "####################Add linux scripts finished####################" admin@PicOS-OVS$sudo reboot ... ...

Example 2:
Run script when OVS is ready.
admin@PicOS-OVS$sudo touch /cftmp/auto/post-ovs admin@PicOS-OVS$sudo chmod 777 /cftmp/auto/post-ovs admin@PicOS-OVS$sudo vi /cftmp/auto/post-ovs echo "Start add ovs scripts" ovs-vsctl del-br br0 ovs-vsctl add-br br0 ovs-vsctl add-port br0 te-1/1/1 ovs-vsctl add-port br0 te-1/1/2 ovs-vsctl add-port br0 te-1/1/3 ovs-ofctl add-group br0 group_id=1,type=select,bucket=output:2,bucket=output:3 ovs-ofctl add-meter br0 meter=1,kbps,stats,band=type=drop,rate=10000 ovs-ofctl add-flow br0 in_port=1,actions=meter:1,group:1 echo "Add ovs scripts finished" admin@PicOS-OVS$sudo systemctl restart picos ..........................
Example 3:
Run script when Xorplus is ready.
admin@XorPlus$sudo touch /cftmp/auto/post-xorplus admin@XorPlus$sudo chmod 777 /cftmp/auto/post-xorplus admin@XorPlus$sudo vi /cftmp/auto/post-xorplus echo "Start add xorplus scripts" /usr/bin/cli -c 'configure; set interface gigabit-ethernet te-1/1/1 crossflow enable true; set interface gigabit-ethernet te-1/1/1 crossflow local-control false; set interface gigabit-ethernet te-1/1/2 crossflow enable true; set interface gigabit-ethernet te-1/1/2 crossflow local-control false; set interface gigabit-ethernet te-1/1/3 crossflow enable true; set xovs enable true; commit' ovs-vsctl del-br br0 ovs-vsctl add-br br0 ovs-vsctl add-port br0 te-1/1/1 ovs-vsctl add-port br0 te-1/1/2 ovs-vsctl add-port br0 te-1/1/3 -- set interface te-1/1/3 type=crossflow ovs-ofctl add-group br0 group_id=1,type=select,bucket=output:2,bucket=output:3 ovs-ofctl add-meter br0 meter=1,kbps,stats,band=type=drop,rate=10000 ovs-ofctl add-flow br0 in_port=1,actions=meter:1,group:1 echo "Add xorplus scripts finished" admin@PicOS-OVS$sudo systemctl restart picos .......................... root@XorPlus> Execute command: configure.
