=== Plugin and packaging changes
|
|
|
|
|
|
|
|
|
|
==== Symbolic links and paths
|
|
|
|
|
|
|
|
|
|
Elasticsearch 2.0 runs with the Java security manager enabled and is much more
|
|
|
|
|
restrictive about which paths it is allowed to access. Various paths can be
|
|
|
|
|
configured, e.g. `path.data`, `path.scripts`, `path.repo`. A configured path
|
|
|
|
|
may itself be a symbolic link, but no symlinks under that path will be
|
|
|
|
|
followed (with the exception of `path.scripts`, which does follow symlinks).
|
|
|
|
|
|
|
|
|
|
==== Running `/bin/elasticsearch`
|
|
|
|
|
|
|
|
|
|
The command line parameter parsing has been rewritten to deal properly with
|
|
|
|
|
spaces in parameters. All config settings can still be specified on the
|
|
|
|
|
command line when starting Elasticsearch, but they must appear after the
|
|
|
|
|
built-in "static parameters", such as `-d` (to daemonize) and `-p` (the PID path).
|
|
|
|
|
|
|
|
|
|
For instance:
|
|
|
|
|
|
|
|
|
|
[source,sh]
|
|
|
|
|
-----------
|
|
|
|
|
/bin/elasticsearch -d -p /tmp/foo.pid --http.cors.enabled=true --http.cors.allow-origin='*'
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
For a list of static parameters, run `/bin/elasticsearch -h`
|
|
|
|
|
|
|
|
|
|
==== `-f` removed
|
|
|
|
|
|
|
|
|
|
The `-f` parameter, which used to indicate that Elasticsearch should be run in
|
|
|
|
|
the foreground, was deprecated in 1.0 and removed in 2.0.
|
|
|
|
|
|
|
|
|
|
==== `V` for version
|
|
|
|
|
|
|
|
|
|
The `-v` parameter now means `--verbose` for both `bin/plugin` and
|
|
|
|
|
`bin/elasticsearch` (although it has no effect on the latter). To output the
|
|
|
|
|
version, use `-V` or `--version` instead.
|
|
|
|
|
|
|
|
|
|
==== Plugin manager should run as root
|
|
|
|
|
|
|
|
|
|
The permissions of the `config`, `bin`, and `plugins` directories in the RPM
|
|
|
|
|
and deb packages have been made more restrictive. The plugin manager should
|
|
|
|
|
be run as root otherwise it will not be able to install plugins.
|
|
|
|
|
|
|
|
|
|
==== Support for official plugins
|
|
|
|
|
|
|
|
|
|
Almost all of the official Elasticsearch plugins have been moved to the main
|
|
|
|
|
`elasticsearch` repository. They will be released at the same time as
|
|
|
|
|
Elasticsearch and have the same version number as Elasticsearch.
|
|
|
|
|
|
|
|
|
|
Official plugins can be installed as follows:
|
|
|
|
|
|
|
|
|
|
[source,sh]
|
|
|
|
|
---------------
|
|
|
|
|
sudo bin/plugin install analysis-icu
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
Community-provided plugins can be installed as before.
|
|

|
|
==== Repository naming structure changes
|
|
|
|
|
|
|
|
|
|
Elasticsearch 2.0 changes the way the repository URLs are referenced. Instead
|
|
|
|
|
of specific repositories for both major and minor versions, the repositories will
|
|
|
|
|
use a major version reference only.
|
|
|
|
|
|
|
|
|
|
The URL for apt packages now uses the following structure;
|
|
|
|
|
|
|
|
|
|
[source,sh]
|
|
|
|
|
---------------
|
|
|
|
|
deb http://packages.elastic.co/elasticsearch/2.x/debian stable main
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
And for yum packages it is;
|
|
|
|
|
|
|
|
|
|
[source,sh]
|
|
|
|
|
---------------
|
|
|
|
|
baseurl=http://packages.elastic.co/elasticsearch/2.x/centos
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
The <<setup-repositories, repositories>> page details this change.
