I tried to start by switching to another user and tried sudo ./elasticsearch and got the same error. How to start elasticity search as root user?

You cannot run elasticsearch as root. This is not allowed and is very dangerous.

Read the installation guide to understand how to properly install it depending on your host.

The root cause of this problem is: ElasticSearch is not allowed to run from the root owner. There is another possibility for this problem: "The Java path is set for the root user, not only for all other users." The solution to this problem:

Step 1: Change the ownership of the elasticSearch directory from root to another user at the command. $ sudo chown -R current_User: Group_Name elasticsearch-5.5.0

Setp 2: Check Java installed in the classpath for the current user [not just root]. If the command: $ java -version or echo $ The JAVA_HOME command gives an empty result. This means that we must install Java in the classpath [system env varible] for the current user, and then perform step 3. otherwise, start the elasticsearch service.

Step 3: edit / etc / profile and add two lines according to your system. export JAVA_HOME = "Location of Java dir"

export PATH = $ JAVA_HOME / bin: $ PATH Running $ source source / etc / profile

After that, the flexibleSearch service starts. It worked great for me.

I had the same problem and had to contact another user. But first, I had to give him permission to perform a bin / elastics search.

This was previously set for ES2 ( How to start Elasticsearch 2.1.1 as root user in a Linux machine )

The same solution can work at 5.

As stated earlier, you probably shouldn't do this.
