Troubleshooting Linux under Root run Elasticsearch exception

Run Elasticsearch 2.3 on CentOS 6.5 with the following exceptions:

ExceptioninchThread"Main"Java.lang.RuntimeException:don ' tRunElasticsearch asRoot. atOrg.elasticsearch.bootstrap.Bootstrap.initializeNatives (Bootstrap.java: the) atOrg.elasticsearch.bootstrap.Bootstrap.setup (Bootstrap.java:144) atOrg.elasticsearch.bootstrap.Bootstrap.init (Bootstrap.java: the) atOrg.elasticsearch.bootstrap.Elasticsearch.main (Elasticsearch.java: *) Refer to  the Log  forCompleteErrorDetails.

The exception is described as unable to run Elasticsearch with root privileges. The workaround is to add parameters at run time:

bin/elasticsearch -Des.insecure.allow.root=true

or modify Bin/elasticsearch, plus the Es_java_opts property:

ES_JAVA_OPTS="-Des.insecure.allow.root=true"

Restart Elasticsearch after saving.
