These are not different ways to start Arango. These are different tools that can be used with Arango 

<a href="https://www.arangodb.com/docs/stable/programs-arangosh.html" rel="nofollow noreferrer">arangosh</a> is a shell tool that an be used to administer the DB as well as running ad-hoc queries. It does not start a server, it only starts the shell that connects to a server

<a href="https://www.arangodb.com/docs/stable/programs-arangod.html" rel="nofollow noreferrer">arangod</a>: This is the deamon that runs when you start Arangodb. In fact, to start the server you usually run (at least on Mac) <code>/usr/local/Cellar/arangodb/3.4.0/sbin/arangod</code> 

<a href="https://www.arangodb.com/docs/stable/installation-mac-osx.html" rel="nofollow noreferrer">arangodb</a>: This is the db install package. For example, in the Mac you would run <code>brew install arangodb</code> to install arangodb on your machine

arangocli: This is simply a cli tool to run ad-hoc queries.

<code>arangod</code> starts a single ArangoDB server, which is sufficient to run a Single Instance deployment. To run more complex deployments (e.g. Cluster, Active Failover) multiple <code>arangod</code> processes are required.

For example a Cluster with 3 agents, 2 dbservers and 2 coordinators requires 8 <code>arangod</code> processes in total. More can be found in the <a href="https://www.arangodb.com/docs/stable/deployment-cluster-manual-start.html#local-tests" rel="nofollow noreferrer">Cluster - Manual Start</a> documentation.

In order to simplify the deployment it is recommended to use the <code>arangodb</code> starter tool. The execution of <code>arangodb</code> initializes an <code>arangod</code> process for each dbserver, coordinator and agent. E.g. using <code>arangodb --starter.local</code> to start a local 3 node cluster starts 9 <code>arangod</code> processes internally: 3 dbservers, 3 coordinators and 3 agents. The running <code>arangod</code> processes can be checked with <code>ps auxw | grep arangod</code>.

An exemplary output can be seen below:

When specifying an option with the starter <code>arangodb</code> as <code>--server.storage-engine rocksdb</code>, this option is passed to all the starter's <code>arangod</code> processes.

A detailed overview for various deployment modes can be found in the documentation's <a href="https://www.arangodb.com/docs/stable/deployment.html" rel="nofollow noreferrer">Deployment</a> chapter.

I am evaluation ArangoDB and figured there are at least 3 ways to start the DB.

<ol>
<li>arangosh</li>
<li>arangod</li>
<li>arangodb</li>
<li>arangocli - this one would fall into a different category</li>
</ol>

This is all very confusing, can someone provide visibility about the different options and what is the best way to start the engine.

Thank you

Why so many different ways to start a ArangoDB

数据库

服务器

我正在评估ArangoDB，我认为至少有3种方法可以启动数据库。arangosharangodarangodbarangocli -这将属于不同的类别这一切都非常令人困惑，有人可以提供不同选项的可见性，以及启动引擎的最佳方式。谢谢
