Gateway Configuration

1.Remove openvswitch

rmmod openvswitch

2.安裝相關套件

yum install -y kmod-iovisor-1.0.6_32_g9c1753e-0.3.10.0_327.el7.x86_64.el7.x86_64.rpm
yum install -y plumgrid-lxc-5.2-0.b8.20160902.053233.x86_64.rpm
yum install -y plumgrid-pythonlib-5.2-0.b8.x86_64.rpm

3.Install the PLUMgrid networking module

yum install -y python-pip
pip install networking-plumgrid==2016.1.1.2

NOTE: 你也可以直接到Pypi下載plumgrid-2016.1.1.2.tar.gz 安裝。

4.Enable IPv4 forwarding:

$ sysctl -w net.ipv4.ip_forward=1

5.Edit /etc/sysctl.conf and add the following content to it:

net.ipv4.ip_forward=1

6.Create the file, /etc/sudoers.d/ifc_ctl_sudoers and add the following content to it:

nova ALL=(root) NOPASSWD: /opt/pg/bin/ifc_ctl_pp *

Modify permissions for /etc/sudoers.d/ifc_ctl_sudoers

chown root:root /etc/sudoers.d/ifc_ctl_sudoers 
chmod 644 /etc/sudoers.d/ifc_ctl_sudoers

Configure PLUMgrid Services on Gateway nodes

1.Create /var/lib/libvirt/filesystems/plumgrid-data/conf/pg/plumgrid.conf and add the following content:

plumgrid_ip=<Management IP address of PLUMgrid Director> 
plumgrid_port=8001 
mgmt_dev=<Management Interface> 
label=<HOSTNAME OF THE MACHINE> 
plumgrid_rsync_port=2222 
plumgrid_rest_addr=0.0.0.0:9180 
fabric_mode=host 
plumgrid_syslog_ng_ip= 
plumgrid_syslog_ng_port= 
plumgrid_monitor_interval= 
start_plumgrid_iovisor=yes 
start_plumgrid=`/opt/pg/scripts/pg_is_director.sh $plumgrid_ip` 
location=

2.Add hostname of the Gateway node to the file /var/lib/libvirt/filesystems/plumgrid-data/conf/etc/hostname. NOTE: Create the file, if it does not exist. The hostname of the node can be found by running the command.

hostname -f

3.Create the file /var/lib/libvirt/filesystems/plumgrid-data/conf/etc/hosts and add the following content to it:

127.0.0.1   localhost 
127.0.1.1   <FQDN> <Hostname>

4.Create the file, /var/lib/libvirt/filesystems/plumgrid-data/conf/pg/ifcs.conf and add the following content to it:

<fabric_interface e.g. br-fabric> = fabric_core host 
<external access interface e.g. ens4> = access_phys

5.Restart the PLUMgrid service:

service plumgrid start
