Installing ArangoDB on Linux
============================
To install ArangoDB on Linux:
- Visit the official [Download](https://www.arangodb.com/download) page of the
ArangoDB web site and download the correct package for your Linux distribution.
You can find binary packages for the most common distributions there.
- Follow the instructions to use your favorite package manager for the
major distributions. After setting up the ArangoDB repository you can
easily install ArangoDB using _yum_, _aptitude_, _urpmi_ or _zypper_.
- Debian based packages will ask for a password during installation. For an
unattended installation for Debian, see [below](#unattended-installation).
Red-Hat based packages will set a random password during installation.
For other distributions or to change the password, run
`arango-secure-installation` to set a root password.
- Alternatively, see [Compiling](Compiling.md) if you want to build ArangoDB
yourself.
After installation, the ArangoDB Server can be started with a command like the
following:
1. Visit the official [Download](https://www.arangodb.com/download) page of the
ArangoDB web site and download the correct package for your Linux distribution.
You can find binary packages for the most common distributions there. Linux Mint:
please use the corresponding Ubuntu or Debian packages.
2. Follow the installation instructions on the _Download_ page to use your
favorite package manager for the major distributions. After setting up the ArangoDB
repository you can easily install ArangoDB using _yum_, _aptitude_, _urpmi_ or _zypper_.
unix> /etc/init.d/arangod start
The above command will start the server, and do that as well at system boot time.
{% hint 'info' %}
In addition to installation packages (distribution dependent) a `tar.gz` archive
is available starting from version 3.4.0.
{% endhint %}
To stop the server you can use the following command:
After installation, you may start ArangoDB in several ways. The exact start-up command
depends on your Linux distribution, as well as on the type of ArangoDB deployment you
are interested in (_Single Server_, _Master-Slave_, _Active Failover_, _Cluster_, _DC2DC_).
unix> /etc/init.d/arangod stop
Please refer to the [_Deployment_](../Deployment/README.md) chapter for details.
The exact commands depend on your Linux distribution.
You may require root privileges to execute these commands.
Securing your Installation

### Debian / Ubuntu
Please use the corresponding Ubuntu or Debian packages.
Debian based packages will ask for a password during installation.
Unattended Installation
-----------------------
#### Securing Unattended Installations on Debian
Debian based package will ask for a password during installation.
For unattended installation, you can set the password using the
[debconf helpers](http://www.microhowto.info/howto/perform_an_unattended_installation_of_a_debian_package.html).
For unattended installations, you can set the password using the
[debconf helpers](http://www.microhowto.info/howto/perform_an_unattended_installation_of_a_debian_package.html):
```
echo arangodb3 arangodb3/password password NEWPASSWORD | debconf-set-selections
echo arangodb3 arangodb3/password_again password NEWPASSWORD | debconf-set-selections
```
The commands should be executed prior to the installation.
The commands above should be executed prior to the installation.
Red-Hat based packages will set a random password during installation.
If you want to force a password, execute
### Red-Hat / CentOS
Red-Hat based packages will set a random password during installation. The generated
random password is printed during the installation. Please write it down somewhere,
or change it to a password of your choice by executing:
```
ARANGODB_DEFAULT_ROOT_PASSWORD=NEWPASSWORD arango-secure-installation

The command should be executed after the installation.
Non-Standard Installation
-------------------------
### Other Distributions
If you compiled ArangoDB from source and did not use any installation
package or using non-default locations and/or multiple ArangoDB
instances on the same host you may want to start the server process
manually. You can do so by invoking the arangod binary from the command
line as shown below:
For other distributions run `arango-secure-installation` to set a _root_ password.
```
unix> /usr/local/sbin/arangod /tmp/vocbase
20ZZ-XX-YYT12:37:08Z [8145] INFO using built-in JavaScript startup files
20ZZ-XX-YYT12:37:08Z [8145] INFO ArangoDB (version 1.x.y) is ready for business
20ZZ-XX-YYT12:37:08Z [8145] INFO Have Fun!
```
To stop the database server gracefully, you can
either press CTRL-C or by send the SIGINT signal to the server process.
On many systems this can be achieved with the following command:
unix> kill -2 `pidof arangod`
Once you started the server, there should be a running instance of *_arangod_* -
the ArangoDB database server.
unix> ps auxw | fgrep arangod
arangodb 14536 0.1 0.6 5307264 23464 s002 S 1:21pm 0:00.18 /usr/local/sbin/arangod
If there is no such process, check the log file
*/var/log/arangodb/arangod.log* for errors. If you see a log message like
2012-12-03T11:35:29Z [12882] ERROR Database directory version (1) is lower than server version (1.2).
2012-12-03T11:35:29Z [12882] ERROR It seems like you have upgraded the ArangoDB binary. If this is what you wanted to do, please restart with the --database.auto-upgrade option to upgrade the data in the database directory.
2012-12-03T11:35:29Z [12882] FATAL Database version check failed. Please start the server with the --database.auto-upgrade option
make sure to start the server once with the *--database.auto-upgrade* option.
Note that you may have to enable logging first. If you start the server
in a shell, you should see errors logged there as well.
{% hint 'danger' %}
Please be aware that running `arango-secure-installation` on your ArangoDB Server will remove
all current database users but root.
