Elasticsearch installation

As per the install wiki [https://www.elastic.co/guide/en/elasticsearch/reference/current/zip-targz.html#install-targz] I have the elasticsearch-5.4.3 installed.

./bin/elasticsearch gave the following error :

    Elasticsearch requires at least Java 8 but your Java version    
    from /usr/bin/java does not meet this requirement

So I have downloaded the latest version of java as well in the same directory as that of elasticsearch.

But running the following command still errors out

    ./jre1.8.0_151/bin/java ./elasticsearch-5.4.3/bin/elasticsearch

with error message : 

    Error: Could not find or load main class ..elasticsearch-5.4.3.bin.elasticsearch

What could be the remedy for this ?

Possibility 1: don't start with java, run elasticsearch directly

step 1: set the $JAVA_HOME to your latest 1.8 java installation

step 2: run the command ./bin/elasticsearch

Possibility 2: permission issue

step 1: set SELinux to permissive mode

step 2: run the installation command from the same user from which you have downloaded and extracted the elasticsearch packages.

first install your java (version 8+) and set $JAVA_HOME variable or download java. use update-alternative to set default java.

update-alternatives: warning: /etc/alternatives/java is dangling

then, install elasticsearch from rpm file and config /etc/elasticsearch/elasticsearch.yml.

now, you can start elasticseach service by executing :

service elasticsearch start
