Modifying the UForge IP

Note

This procedure is only valid for mono node UForge platforms. For an example of modify the IP in a multi-node environment, refer to Modifying the UForge IP in a Multi-Node Environment.

To modify the UForge IP you will need to:

  1. Stop the following services:

    service tomcat stop
service oar-server stop
service squid stop
service rabbitmq-server stop
service eventcontroller stop

  2. Clean the squid cache as follows:

    [root@db ~]# grep cache_dir /etc/squid/squid.conf
cache_dir ufs /data/proxy 10000 16 256
[root@db ~]# rm -rf /data/proxy/*

  3. Modify all occurences of the old IP to the new IP in the following files:

    • /etc/UShareSoft/uforge/uforge.conf
    • /var/opt/UShareSoft/uforge-client/gwt/uforge/templates/forge-config.xml
    • /etc/httpd/conf.d/uforge-ui.conf
    • /etc/squid/squid.conf

For example:

sed -i.bak "s/192\.168\.2\.177/192.168.2.200/g" /etc/UShareSoft/uforge/uforge.conf /var/opt/UShareSoft/uforge-client/gwt/uforge/templates/forge-config.xml /etc/httpd/conf.d/uforge-ui.conf /etc/squid/squid.conf

  1. Modify all occurences of the old IP to the new IP in the following files:

    • /etc/sysconfig/network-scripts/ifcfg-ens160
    • /etc/hosts

For exemple:

sed -i "s/192\.168\.2\.177/192.168.2.200/g" /etc/sysconfig/network-scripts/ifcfg-ens160 /etc/hosts

  1. Restart the network service:

    service network restart

Note

You will need to open a new terminal and connect to the machine using the new IP.

  1. Restart the services as follows:

    $ /opt/UShareSoft/uforge/tools/update_scripts/uforge_update.sh
$ /opt/UShareSoft/uforge-client/bin/uforge_ui_update.sh
$ service oar-server start

Note

While oar-server is down, root user may receive emails with an error message about UForge cron execution.

Modifying the UForge IP in a Multi-Node Environment

The following is an example of modifying the UForge IP in a multi-node environment. This example should be modified to correspond to your platform configuration.

The environment in this example has four nodes:

  • Node 1 for the UI
  • Node 2 for the Web Service
  • Node 3 for the DB with the OAR service Manager, RabbitMQ and UForge Event Controller
  • Node 4 for the Compute Node

Old DB IP: 10.1.2.180

New DB IP: 10.1.2.25

  1. Stop the following services:

    On the WS node and UI node run:

    $ service tomcat stop

    On the DB node run:

    $ service oar-server stop
$ service squid stop
$ service rabbitmq-server stop
$ service eventcontroller stop

  2. Clean the Squid cache as follows:

    Search and delete the cache directory in the DB node

    $ grep cache_dir /etc/squid/squid.conf
 cache_dir ufs /data/proxy 10000 16 256
$ rm -rf /data/proxy/*

  3. Modify all occurences of the old IP to the new IP in the following files:

    Modify uforge.conf and squid.conf modification in all nodes:

    $ sed -i.bak "s/10.1.2.180/10.1.2.25/g" /etc/UShareSoft/uforge/uforge.conf
$ sed -i.bak "s/10.1.2.180/10.1.2.25/g" /etc/squid/squid.conf

    If the IP of the UI node or WS node was changed, the following files have to be modified on UI node:

    • /var/opt/UShareSoft/uforge-client/gwt/uforge/templates/forge-config.xml
    • /etc/httpd/conf.d/uforge-ui.conf

  4. Modify all occurences of the old IP to the new IP in the following files:

    Modify ifcfg-ens160 only on the node which IP will be changed

    $ sed -i  "s/10.1.2.180/10.1.2.25/g" /etc/sysconfig/network-scripts/ifcfg-ens192

    Modify /etc/hosts on all nodes

    $ sed -i  "s/10.1.2.180/10.1.2.25/g" /etc/hosts for each node

  5. Restart the network service only for the node where the IP has been changed:

    $ service network restart

  6. Restart the services as follows:

    1. Execute uforge_update.sh script on all nodes in the next order:

      • Compute node
      • DB node
      • WS node
      • UI node
    $ /opt/UShareSoft/uforge/tools/update_scripts/uforge_update.sh

    1. Start oar-server in the DB node:

      $ service oar-server start

    2. If the IP of the UI node or WS node was changed, the next script has to be executed in the UI node:

      $ /opt/UShareSoft/uforge-client/bin/uforge_ui_update.sh
