plone.recipe.zeoserver 3.0.0

Options

The following options all affect the generated zeo.conf. If you want to have full control over the configuration file, see the zeo-conf option in the advanced options.

Process

zeo-address

Give a port for the ZEO server (either specify the port number only (with ‘127.0.0.1’ as default) or you use the format host:port). Defaults to 8100.

effective-user

The name of the effective user for the ZEO process. Defaults to not setting an effective user. This causes the process to run under the user account the process has been started with.

socket-name

The filename where ZEO will write its socket file. Defaults to var/zeo.zdsock.

Storage

storage-number

The number used to identify a storage. Defaults to 1.

file-storage

The filename where the ZODB data file will be stored. Defaults to var/filestorage/Data.fs.

blob-storage

The folder where the ZODB blob data files will be stored. Defaults to var/blobstorage.

Logging

zeo-log

The filename of the ZEO log file. Defaults to var/log/${partname}.log.

zeo-log-level

Control the logging level in the eventlog. Defaults to info.

zeo-log-max-size

Maximum size of ZEO log file. Enables log rotation.

zeo-log-old-files

Number of previous log files to retain when log rotation is enabled. Defaults to 1.

zeo-log-format

Format of logfile entries. Defaults to %(asctime)s %(message)s.

zeo-log-custom

A custom section for the eventlog, to be able to use another event logger than logfile. zeo-log is still used to set the logfile value in the runner section.

Authentication

authentication-database

The filename for a authentication database. Only accounts listed in this database will be allowed to access the ZEO server.

The format of the database file is:

realm <realm>
<username>:<hash>

Where the hash is generated via:

import sha
string = "%s:%s:%s" % (username, realm, password)
sha.new(string).hexdigest()

authentication-realm

The authentication realm. Defaults to ZEO.

Packing

pack-days

How many days of history should the zeopack script retain. Defaults to one day.

pack-gc

Can be set to false to disable garbage collection as part of the pack. Defaults to true.

pack-keep-old

Can be set to false to disable the creation of *.fs.old files before the pack is run. Defaults to true.

pack-user

If the ZEO server uses authentication, this is the username used by the zeopack script to connect to the ZEO server.

pack-password

If the ZEO server uses authentication, this is the password used by the zeopack script to connect to the ZEO server.

ZRS

First off, you’ll need to specify the recipe to install zc.zrs. To do so, just slightly change the way the recipe option is specified in your zeoserver buildout part:

[zeoserver]
recipe = plone.recipe.zeoserver[zrs]
...

replicate-to

host:port combination this ZRS should listen to as a primary. ZRS Secondaries connect here to get replication data.

replicate-from

host:port combination of a ZRS primary this ZRS should connect to as a secondary. This ZRS replicates the data it gets from the primary.

keep-alive-delay

In some network configurations, TCP connections are broken after extended periods of inactivity. This may even be done in a way that a client doesn’t detect the disconnection. To prevent this, you can use the keep-alive-delay option to cause the secondary storage to send periodic no-operation messages to the server.

Monitoring

monitor-address

The address at which the monitor server should listen. The monitor server provides server statistics in a simple text format.

Performance

invalidation-queue-size

The invalidation-queue-size used for the ZEO server. Defaults to 100.

Customization

var

Used to configure the base directory for all things going into var. Defaults to ${buildout:directory}/var.

zeo-conf-additional

Give additional lines to zeo.conf. Make sure you indent any lines after the one with the parameter. This allows you to use generated zeo.conf file but add some minor additional lines to it.

eggs

Set if you need to include other packages as eggs e.g. for making application code available on the ZEO server side for performing conflict resolution (through the _p_resolveConflict() handler).

extra-paths

Specify additional directories which should be available to the control scripts. Use this only for non-eggified Python packages.

zeo-conf

A relative or absolute path to a zeo.conf file. This lets you provide a completely custom configuration file and ignore most of the options in this recipe.

repozo

The path to the repozo.py backup script. A wrapper for this will be generated in bin/repozo, which sets up the appropriate environment for running this. Defaults to using the repozo script from the ZODB egg. Set this to an empty value if you do not want this script to be generated.

repozo-script-name

The name of the wrapper script to generate in bin/. Defaults to repozo. Change this option if you have more than one instance of this recipe in the one buildout to create separate scripts and avoid any one script being overwritten.

zeopack

The path to the zeopack.py backup script. A wrapper for this will be generated in bin/zeopack (unless you change zeopack-script-name), which sets up the appropriate environment to run this. Defaults to using the zeopack script from the ZODB egg. Set this option to an empty value if you do not want this script to be generated.

zeopack-script-name

The name of the wrapper script to generate in bin/. Defaults to zeopack. Change this option if you have more than one instance of this recipe in the one buildout to create separate scripts and avoid any one script being overwritten.

relative-paths

Set this to true to make the generated scripts use relative paths. You can also enable this in the [buildout] section.

read-only

Set zeoserver to run in read-only mode

Usage

zeopack

A zeopack script will be generated for you in the buildout bin directory, unless you change the zeopack-script-name option, in which case the script will be called the name you specify. If you’d like to use this script to pack a different mount point, you’ll need to specify -S mount_name. You can also specify a -B option to not use the default blob directory. You may override the pack-days by adding “-D #” to the command line where “#” is the number of days to keep.

• Fix custom zeo.conf support under windows. [rossp]

1.2.1 - 2011-09-12

1.1.1 - 2010-07-20

• Fixed -B option being required for along with the -S option. [vangheem]

• Added documentation for using the zeopack script with mount points. [vangheem]

1.1 - 2010-07-18

• No changes.

1.1b1 - 2010-07-02

• Implemented Windows support and support for running ZEO as a Windows service. We depend on the new nt_svcutils distribution to provide this support. [baijum, hannosch]

• The FileStorage component of ZODB 3.9 now supports blobs natively, so no need to use BlobStorage proxy for it anymore. [baijum, hannosch]

• Added extra-paths option to add additional modules paths. [baijum]

• Added support for the pack-keep-old option introduced in ZODB 3.9. [hannosch]

1.1a1 - 2010-04-27

• Added support for the pack-gc option introduced in ZODB 3.9. [hannosch]

• Always create a blob-storage by default. [hannosch]
