Following are examples of commands that create and delete a logical load balancer group.
When creating a logical load balancer group, a service IP address is usually on a public network.
C:\> ioexec creategroup logicalloadbalancer -s example-io-service -l
LogicalLoadBalancer:00000000-0000-0000-0000-000000000000 -g http-group
-P http -a 10.1.100.10 -p 80 -H example-website -U "/" -t 6000 -O
JSESSIONID -u administrator
C:\> ioexec deletegroup logicalloadbalancer -s example-io-service -l
LogicalLoadBalancer:00000000-0000-0000-0000-000000000000 -g http-group
-u administrator
where:
-s example-io-service
IO service name in which to add the logical load balancer
group
-l LogicalLoadBalancer:
00000000-0000-0000-0000-000000000000 Logical load balancer ID, located on the on the Services
tab. To view the ID, select a service and click Details, then
select the Load Balance tab
-g http-group Name of the group to be added to the load balancer. This
is an arbitrary name specified by an administrator for easy
recognition
-P http Type of protocol the application service will use
-a 10.1.100.10 IP address to be used for incoming requests
-p 80 Port on which the load balancer listens
-H example-host.com Host name of the application service to be load balanced
-U "/" URI path of the service to be load balanced. Specifying “/”
(the root path) does not restrict access. To restrict access,
specify a path such as “/mystore”. In this case, a request
to http://host/ will not succeed, but a request to
http://host/mystore/mydepartment will succeed
-t 6000 Session timeout, in seconds
-O JSESSIONID Name or ID of an http(s) cookie to store session information
-u administrator user name for the ioexec CLI
NOTE: The SSL certificate for an https create load balancer group request must be
an X.509 certificate in DER format, with the private key included. The administrator generates this
certificate and ensures that it is signed:
F5 SSL Certificate
Adding and removing group members from a logical load balancer group
After deploying a service and creating a logical load balancer group, IO administrators can use
the following ioexec commands to add and remove servers from a logical load balancer group.
Table 3 ioexec add and remove load balancer group commands
Description ioexec command
Adds a member to a logical load balancer group addgroupmember logicalloadbalancer
Removes a member from a logical load balancer group removegroupmemger
logicalloadbalancer
In the following examples, the ioexec addgroupmember logicalloadbalancer command
adds one server to the load balancer. The options are similar to the options in the creategroup
