You can find the components' current version numbers by querying the Gentics Mesh demo instance https://demo.getmesh.io/api/v2/ or your local instance http://localhost:8080/api/v2/.

Run with Docker

Alternatively you can start Gentics Mesh using Docker via:

The mesh-demo image contains Gentics Mesh together with demo content and our demo application.

docker run -p 8080:8080 gentics/mesh-demo

The mesh image contains an empty Gentics Mesh server without any demo content.

docker run -p 8080:8080 gentics/mesh
or
docker run \
 -v mesh-graphdb:/graphdb \
 -v mesh-uploads:/uploads \
 -p 8080:8080 \
 gentics/mesh

Run with JAR File

Good news: there is no dedicated installation procedure for Gentics Mesh!

All you need is to download the Gentics Mesh JAR file and start by executing

java -jar mesh-demo-X.X.X.jar

Gentics Mesh comes with OrientDB, an embedded graph database, and Elasticsearch. There are no external dependencies besides Java Runtime 11. On first startup, Gentics Mesh will create the data folder and subfolders, set a password for the keystore file and provide the configuration files mesh.yml and mesh-ui-config.js. See Installation Directory for a detailed discussion on Gentics Mesh files & folders.

Command Line Arguments

Various command line arguments can be used to override or supplement previously configured settings.

usage: mesh.jar
 -clusterName <name>              Override the cluster name. Setting a
                                  cluster name will also enable
                                  clustering.
 -disableElasticsearch            Flag which can be used to disable the
                                  Elasticsearch integration.
 -elasticsearchUrl <url>          Elasticsearch URL to be used.
 -help                            This output
 -httpPort <port>                 Override the configured server HTTP
                                  port.
 -initCluster                     Flag which can be used to initialise the
                                  first instance of a cluster. This is
                                  usually only used for testing or setup
                                  of fresh cluster instances.
 -nodeName <name>                 Override the configured node name.

                                  to change the password once again after
                                  the reset has been performed. The
                                  command will also recreate the admin
                                  user if it can't be found in the system.

Installation Directory

On first startup, Gentics Mesh will create all files and folders.

data
   binaryFiles                # Folder for uploads
   binaryImageCache           # Folder for resized and cached images
   graphdb                    # Main Graph Database storage which contains all contents
   tmp                        # Temporary directory

   security.json              # OrientDB security configuration
   mesh-ui-config.js          # Configuration of the Mesh UI

Gentics Mesh ships with two configuration files:

  1. The main configuration file mesh.yml contains all settings for configuring the Gentics Mesh server. All settings are explained in the Configuration & Settings section.

  2. User interface related settings can be changed in mesh-ui-config.js.

All data of your Gentics Mesh instance can be found in the respective subfolders of data.

The folder binaryFiles contains all media assets of your projects including images and other files. binaryImageCache keeps resized versions of requested images. The OrientDB graph data is stored within the graphdb folder. tmp is used by Vert.x and other components e.g. for file uploads.

This folder structure is the default. All paths can be configured in the main configuration file mesh.yml.

The keystore file, by default, is named keystore.jceks. On first startup, a password for the keystore file is created randomly and stored in mesh.yml.

The elasticsearch folder contains the included Elasticsearch installation which will be started by default.

System Requirements

Server Requirements

Gentics Mesh comes with OrientDB, an embedded graph database. There are no external dependencies besides Java Runtime 11.

Production servers must be run on Linux. Windows is not supported. You can however run Gentics Mesh on Windows via Docker Windows.

GraphDB Storage Requirements

The underlying storage filesystem for the Graph Database must support DirectIO.

Filesystem Supported

Ext4

Yes

XFS

Yes

NFS

No

GlusterFS

No

Ceph

No

ZFS

No

Amazon EFS

No

Amazon EBS

Yes

Storage solutions which provide one of the supported filesystems by the means of iSCSI or Fiberchannel are supported.

Gentics Mesh will periodically check the available disk space. If less disk space is available than defined as warn threshold, a warning will be logged. If less disk space is available than defined as read-only threshold, the Mesh instance (in cluster mode all Mesh instances) will be set read-only, so mutating requests will all fail with an appropriate message.

The thresholds can be configured with the configuration settings storage.diskQuota.warnThreshold and storage.diskQuota.readOnlyThreshold either as percentage of the total disk space (e.g. 10%) or as absolute disk space (e.g. 10M). The check interval can be configured with storage.diskQuota.checkInterval (in ms). Setting this to 0 will disable the check.

Cluster Requirements

  • Each Gentics Mesh instance needs at least 1.5 GB heap memory.

  • A shared filesystem needs to be provided for the upload folder. This folder needs to be shared among all cluster instances. Using NFS is a typical choice for these folders.

System Configuration

The maximum open file limit on Linux has to be raised on most Linux systems since the embedded graph database and Elasticsearch server often exceed the amount of concurrent open files.

The limits need to be configured specific to your execution environment.

  • Docker: Limits can be specified during startup or inside the docker-compose.yaml.

  • Systemd: Limits can be specified within the startup service file.

  • K8S/Openshift: Limits need to be configured in the deployments. The commercial helm chart already includes these.

  • sysvinit: The limits can be configured in the /etc/security/limits.conf

Edit /etc/security/limits.conf and add these two lines:

mesh   soft    nofile  60000
mesh   hard    nofile  60000

Edit /etc/pam.d/su and uncomment or add the following line:

session    required   pam_limits.so
This change may require a logout and login.

Client Requirements

The Gentics Mesh user interface has been designed mobile-first and does not impose any specific requirements other than enabled JavaScript. It can be used with any "modern" browser, i.e. IE11+ and latest versions of Chrome, Firefox, and Safari.

General Settings

Configuration Type Default Description

updateCheck

Flag

true

An update check to the Gentics Mesh update server will be invoked during startup if this flag is set to true.

defaultLanguage

String

en

Default language which serves as a fallback when no language has been specified within a request.

verticles

List

-

List of Vert.x java verticle classes which will be loaded during startup.

tempDirectory

Path

data/tmp

Path to the main temporary filesystem directory.

languagesFilePath

Path

-

startInReadOnly

Flag

false

If true, Gentics Mesh will be started in read only mode.

versionPurgeMaxBatchSize

Number

10

The maximum amount of node versions that are purged before the database transaction is committed.

Custom Language

By default Gentics Mesh already contains all ISO 639-1 (two letter) language codes. By using the languagesFilePath setting it is possible to provide a custom languages file which can include additional language definitions.

{
    "sq-KS": {
        "name": "Albanian (Kosovo)",
        "nativeName": "Shqip (Kosovo)"
    }
}
Please note that the contentLanguages property in the mesh-ui2-config.js file also needs to be updated in order to show the language in the UI.
The mesh-compose project contains a full example configuration which shows how to add a custom language.

Memory Settings

Memory settings can be defined using the JAVA_TOOL_OPTIONS environment variable.

Setting Description

-Xmx

Maximum heap size of the Gentics Mesh Java process

-Xms

Initial heap size of the Gentics Mesh Java process

-Xss

Stack size. A larger stack size may be required when deleting deep datasets. The default value is 1MB.

-XX:MaxDirectMemorySize

Maximum direct memory limit. Direct memory is mostly used for IO buffers.

-Dstorage.diskCache.bufferSize

Disk buffer size in megabytes used for the graph database. The disk cache will make use of direct memory that is independent of the above setting.

The total amount of required memory is the roughly sum of heap memory + direct memory + disk cache + (stack size * thread count) + 256 MB (OrientDB + JVM base memory).

Admin Access

By default an admin user will be created during initial startup. The password of this user will be printed in the log. It is mandatory to update the admin password during the first login.

For demo installations the password is admin.

Additional admin users can be created by setting the admin flag the users.

The admin access can be restored via the use of the resetAdminPassword mesh server argument.

Backup & Recovery

There are currently fours components which can be included in a backup:

  • Graph Database - The graph database contains the main content of Gentics Mesh. The DB can be backed up on demand via /api/v2/admin/graphdb/backup endpoint or via the OrientDB backup job using automatic-backup.json. This will automatically create a full backup. Note that both backup processes will block the application. The graph database backup process will write a backup file to the configured backup location (see [Storage Location]).

  • Binary files - Binaries are currently stored in the filesystem and need to be backed up separately data/binaryFiles)

  • Elasticsearch Index - Optionally you can also backup the Elasticsearch index. The index can also be re-created anytime using the POST /api/v2/search/sync endpoint.

  • Configuration - The Gentics Mesh configuration files should be part of a backup. Especially the keystore.jks file is important since it contains the cryptographic keys which are needed to authenticate issued tokens which includes also the API key. The mesh.yaml file contains the autogenerated password for the keystore file. The keystore file and the password to open it are required by Gentics Mesh to authenticate tokens.

The POST /api/v2/admin/graphdb/restore endpoint can be used to restore created backups. The endpoint will utilize the latest backup found in the backup directory.

Invoking the backup/restore endpoints will block all execution and request processing. Reverse proxies may return a timeout error when the request takes too long.
The backup endpoint will only create a backup of the graph database. The other components need to be handled separately.
The restore operation can’t be executed on Mesh instances which have clustering enabled.

If you already run Gentics Mesh in a cluster you can start a dedicated backup instance which can run the backup process without interference of the other nodes.

Take a look at our docker-compose example for a documented setup.

Import & Export

The POST /api/v2/admin/graphdb/export and POST /api/v2/admin/graphdb/import endpoints can be used to generate Graph Database export files which are gzipped json files. A large database can be exported and reimported again to reduce the sparse file size.

Debug Information

The debug info endpoint (GET /api/v2/admin/debuginfo) starts a zip download containing various useful data about the system.

The documentation below lists all files that are included in the zip.

Per default everything except the consistency check is included in the zip. You can use the ?include query parameter to include or exclude specific parts. For example /api/v2/admin/debuginfo?include=-backup,consistencyCheck will exclude the database backup and include the consistency checks.

Active Config

Query name: activeConfig

The effective configuration that is currently used in the system. This includes overrides by command line argument and environment variables.

Binary Disk Usage

Query name: binaryDiskUsage

The total file size of all stored binaries and cached images.

Configurations

Query name: config

The following files from the config folder:

  • mesh.yml

  • hazelcast.xml

  • logback.xml

  • default-distributed-db-config.xml

  • orientdb-server-config.xml

Consistency Check

Query name: consistencyCheck

Performs a consistency check and includes the result.

Database Backup

Query name: backup

Including this will cause the database to be in read only mode for the duration of the backup.

Performs a Graph database backup and includes the files.

Entities

Query name: entities

Includes the following entities as json:

  • All jobs

  • All Schemas

  • All Microschemas

  • All Projects

  • All Branches

Log

Query name: log

Includes the latest debug log output of Gentics Mesh. Check the debug info options for more options.

Query name: migrationStatus

Includes the schema migration status and mircoschema migration status for every branch of every project.

Plugins

Query name: plugins

Includes the currently deployed plugins.

Status

Query name: status

Includes the version, cluster status and elastic search status.

System Information

Query name: systemInfo

Contains the following informations about the system:

  • System load average

  • JVM memory usage

  • JVM arguments

  • Disk space usage (of the file system where Gentics Mesh is running)

Thread Dump

Query name: threadDump

A dump of all threads including all stack traces.

Read Only Mode

Gentics Mesh can be put into read only mode. In this mode, all requests that would change data (create, update, delete) are not allowed and return a `405ยด status code instead.

This is useful in cluster situations when having instances as replicas or when performing rolling updates.

Activating Read Only Mode

Read only mode can be activated in one of the following ways:

  • Setting the entry startInReadOnly to true in the configuration file before starting will start Gentics Mesh in read only mode.

  • Setting the environment variable MESH_START_IN_READ_ONLY to true before starting will start Gentics Mesh in read only mode.

  • Using the REST API. Changing read only mode in this way will take immediate effect.

Changelog

Update handling

Updating Gentics Mesh is very simple. You stop the current instance and start it again using the new version. A process is invoked which will check whether any automatic changes need to be applied.

Downgrading

Downgrading is possible but not recommended. You can however downgrade your Gentics Mesh instance if the database revision hash of the current database matches up with the revision which is required by the version which is being started. You can check your current database revision via the /api/v2 endpoint.

Database Revisions

This list contains an overview over Gentics Mesh releases and the their database revisions. The database revision is different if the used Graph Database version was updated or if the database structure was altered due to an automatic change.

Database Consistency

It is possible to verify the database integrity via the GET /api/v2/admin/consistency/check endpoint.

The response contains information about the found inconsistencies and whether they have a repair action.

{
  "outputTruncated" : false,
  "result" : "INCONSISTENT",
  "repairCount" : { },
  "inconsistencies" : [ {
    "description" : "A dangling field container has been found.",
    "severity" : "LOW",
    "elementUuid" : "c5ac82fa1a9c43b6ac82fa1a9ca3b61c",
    "repaired" : false,
    "repairAction" : "DELETE"
  } ]
}

The POST /api/v2/admin/consistency/repair endpoint can be used to invoke a check and repair of repairable inconsistencies.

The repaired property will be set to true if the inconsistency could be fixed.

{
  "outputTruncated" : false,
  "result" : "INCONSISTENT",
  "repairCount" : { },
  "inconsistencies" : [ {
    "description" : "A dangling field container has been found.",
    "severity" : "LOW",
    "elementUuid" : "c5ac82fa1a9c43b6ac82fa1a9ca3b61c",
    "repaired" : true,
    "repairAction" : "DELETE"
  } ]
}

Filesystem support

The filesystem ZFS (ZFS on Linux) does currently not support Direct IO on Linux.

When using ZFS it is thus required to turn off direct IO usage of OrientDB. Please use the -Dstorage.wal.allowDirectIO=false setting in this case.

The direct IO support will be included in ZFS 0.8
