Cluster reform

- Support for dynamic cluster nodes:

Previous versions of OpenACS required to know the IP addresses of

the cluster nodes in advance, which is a show-stopper for many cloud

applications.

The new functionality allows arbitrary nodes to register as client

nodes at the canonical server, provided that these know a shared

secret. All messages of the intra-cluster talk are now

cryptographically signed using this shared secret.

In the current version, the shared secret key has to be specified in

the NaviServer configuration file (ClusterSecret). Later versions

will support the use of other measures such as generated keys, kept

as files.

Also in the new version it is still possible to use static peer

addresses (which do not have to register during startup).

- Support for multiple protocols for intra-cluster talk

Previous version of OpenACS required the communication of the

intra-cluster talk over HTTP. With these changes, multiple protocols

are supported. Most prominently HTTPS can be used, which is required

by some organization for all web communication, especially for cloud

applications. Other protocols might be added later (e.g. UDP).

- Nodes (such as the canonical server) can be specified via URL

locations. These location specifier have the following advantages

over classical IP address and port.

* support different protocols (http, https, udp)

* support of IP addresses or DNS names

* when DNS names map to multiple IP addresses

(e.g. multiple IPv4 and/or multiple IPv6 addresses)

the new parameter PreferredLocationRegexp can be use

to select the wanted. When this regexp does not match

any of the addresses, the first address is used.

* ports are now optional (except UDP)

* for location specifier: https://openacs.org

- Support for cluster communication statistics

(requires xotcl-request-monitor)

These statistics show the amount of intra-server

communication. The following statistics are collected

per node:

- number of broadcast operations

- number of send operations (active flushes)

- number of receive operation (passive flushes)

For N cluster nodes, the send operations are

basically the number of broadcast operations times

the number of nodes minus one.

These statistics can also be used prior to cluster

enabling, to obtain the number of potential broadcast

operations.

Kernel Parameters

CanonicalServer : location of the canonical server

ClusterAuthorizedIP : obsolete

ClusterEnabledP : unchanged

ClusterPeerIP : obsolete

EnableLoggingP : unchanged

PreferredLocationRegexp : new

DynamicClusterPeers : new, no not edit

Differences between old and new value for "CanonicalServer":

old:

- specify IP address with port

- example: 137.208.116.31:443

new:

- specify URL location

- support different protocols (http, https, udp)

- support of IP address or domain name

- when domain name maps to different IP addresses

(e.g. multiple IPv4 and/or multiple IPv6 addresses)

PreferredLocationRegexp can be use to select the wanted.

When the provided regexp does not match any of

the addresses, take the first address.

- port is optional

- example: https://openacs.org

Sample setup

Old:

CanonicalServer : 137.208.116.31:443

ClusterAuthorizedIP : 137.208.116.31

ClusterPeerIP : 137.208.116.31:443 137.208.116.31:8443

ClusterEnabledP : 1

EnableLoggingP : 1

New:

CanonicalServer : https://openacs.org

PreferredLocationRegexp : https://

ClusterEnabledP : 1

EnableLoggingP : 1

#

# Cluster secret for intra-cluster communications in NaviServer

# configuration file. Clustering will not be enabled if no value is

# provided.

#

ns_section ns/server/$server/acs {

# ...

ns_param ClusterSecret "please change me"

}

#-----------------------------------------------------------------------

# Support for munin statistics

#

# 1) install munin plugins for naviserver (munin-plugins-ns.git)

# 2) add link to the munin plugins (replace "openacs" by the name

# of your server in the munin configuration)

# /etc/munin/plugins/naviserver_openacs_count_cluster -> /usr/share/munin/plugins/naviserver_count

# 3) in the plugin plugin configuration (e.g., etc/munin/plugin-conf.d/naviserver)

# add a section like the following (again, replace "openacs" by the server name you used)

#

# [naviserver_openacs_count_cluster]

# env.title Cluster

# env.vars cluster:broadcast cluster:sent cluster:received

#

# 4) restart munin
