= ${infinispan.brand.name} Server ${infinispan.brand.version}

Welcome to ${infinispan.brand.name} Server!

== Requirements
${infinispan.brand.name} Server requires JDK 11 or later.

== Starting servers
Use the `server` script to run ${infinispan.brand.name} Server instances.

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat
----

[TIP]
====
Include the `--help` or `-h` option to view command arguments.
====

== Stopping servers
Use the [command]`shutdown` command with the CLI to perform a graceful shutdown.

Alternatively, enter Ctrl-C from the terminal to interrupt the server process or kill it via the TERM signal.

== Configuration
Server configuration extends ${infinispan.brand.name} configuration with the following server-specific elements:

`cache-container`:: Defines cache containers for managing cache lifecycles.
`endpoints`:: Enables and configures endpoint connectors for client protocols.
`security`:: Configures endpoint security realms.
`socket-bindings`:: Maps endpoint connectors to interfaces and ports.

The default configuration file is `<SERVER_HOME>/server/conf/infinispan.xml`.

`infinispan.xml`:: Provides configuration to run ${infinispan.brand.name} Server using default cache container with statistics and authorization enabled. Demonstrates how to set up authentication and authorization using security realms.

${infinispan.brand.name} provides other ready-to-use configuration files that are primarily for development and testing purposes.

`<SERVER_HOME>/server/conf/` provides the following configuration files:

`infinispan-dev-mode.xml`:: Configures ${infinispan.brand.name} Server specifically for cross-site replication with IP multicast discovery. The configuration provides `BASIC` authentication to connect to the Hot Rod and REST endpoints. The configuration is designed for development mode and should not be used in production environments.
`infinispan-local.xml`:: Configures ${infinispan.brand.name} Server without clustering capabilities.
`infinispan-xsite.xml`:: Configures cross-site replication on a single host and uses IP multicast for discovery.
`infinispan-memcached.xml`:: Configures ${infinispan.brand.name} Server to behave like a default Memcached server, listening on port 11221 and without authentication.
`infinispan-resp.xml`:: Configures ${infinispan.brand.name} Server to behave like a default Redis server, listening on port 6379 and without authentication.
`log4j2.xml`:: Configures ${infinispan.brand.name} Server logging.

Use different configuration files with the `-c` argument, as in the following example that starts a server without clustering capabilities:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh -c infinispan-local.xml
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat -c infinispan-local.xml
----

== Bind address
${infinispan.brand.name} Server binds to the loopback IP address `localhost` on your network by default.

Use the `-b` argument to set a different IP address, as in the following example that binds to all network interfaces:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh -b 0.0.0.0
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat -b 0.0.0.0
----

== Bind port
${infinispan.brand.name} Server listens on port `11222` by default.

Use the `-p` argument to set an alternative port:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh -p 30000
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat -p 30000
----

== Clustering address
${infinispan.brand.name} Server configuration defines cluster transport so multiple instances on the same network discover each other and automatically form clusters.

Use the `-k` argument to change the IP address for cluster traffic:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh -k 192.168.1.100
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat -k 192.168.1.100
----

== Cluster stacks
JGroups stacks configure the protocols for cluster transport.
${infinispan.brand.name} Server uses the `tcp` stack by default.

Use alternative cluster stacks with the `-j` argument, as in the following example that uses UDP for cluster transport:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh -j udp
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat -j udp
----

== Authentication
${infinispan.brand.name} Server requires authentication.

Create a username and password with the CLI as follows:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/cli.sh user create username -p "qwer1234!"
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\cli.bat user create username -p "qwer1234!"
----

== Server home directory

${infinispan.brand.name} Server uses `infinispan.server.home.path` to locate the contents of the server distribution on the host filesystem.

The server home directory, referred to as `<SERVER_HOME>`, contains the following folders:

[source,options="nowrap",subs=attributes+]
----
├── bin
├── boot
├── docs
├── lib
├── server
└── static
----

[%header,cols=2*]
|===
|Folder
|Description

|`/bin`
|Contains scripts to start servers and CLI.

|`/boot`
|Contains `JAR` files to boot servers.

|`/docs`
|Provides configuration examples, schemas, component licenses, and other resources.

|`/lib`
|Contains `JAR` files that servers require internally. +
Do not place custom `JAR` files in this folder.

|`/server`
|Provides a root folder for ${infinispan.brand.name} Server instances.

|`/static`
|Contains static resources for ${infinispan.brand.name} Console.

|===

== Server root directory

${infinispan.brand.name} Server uses `infinispan.server.root.path` to locate configuration files and data for ${infinispan.brand.name} Server instances.

You can create multiple server root folders in the same directory or in different directories and then specify the locations with the `-s` or `--server-root` argument, as in the following example:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh -s server2
----

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat -s server2
----

Each server root directory contains the following folders:

[source,options="nowrap",subs=attributes+]
----
├── server
│   ├── conf
│   ├── data
│   ├── lib
│   └── log
----

[%header,cols=3*]
|===
|Folder
|Description
|System property override

|`/server/conf`
|Contains server configuration files.
|`infinispan.server.config.path`

|`/server/data`
|Contains data files organized by container name.
|`infinispan.server.data.path`

|`/server/lib`
|Contains server extension files. +
This directory is scanned recursively and used as a classpath.
|`infinispan.server.lib.path` +
Separate multiple paths with the following delimiters: +
`:` on Unix / Linux +
`;` on Windows

|`/server/log`
|Contains server log files.
|`infinispan.server.log.path`

|===

== Logging
Configure ${infinispan.brand.name} Server logging with the `log4j2.xml` file in the `server/conf` folder.

Use the `--logging-config=<path_to_logfile>` argument to use custom paths, as follows:

.Unix / Linux

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>/bin/server.sh --logging-config=/path/to/log4j2.xml
----

TIP: To ensure custom paths take effect, do not use the `~` shortcut.

.Windows

[source,options="nowrap",subs=attributes+]
----
<SERVER_HOME>\bin\server.bat --logging-config=path\to\log4j2.xml
----
