如何解決centos下root運行Elasticsearch異常
在CentOS 6.5 上運行Elasticsearch 2.3,異常如下:
?
1 2 3 4 5 6 Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root. at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:93) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:144) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:270) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35) Refer to the log for complete error details.異常描述為不能以root權限運行Elasticsearch.解決辦法是運行時加上參數:
?
1 bin/elasticsearch -Des.insecure.allow.root=true或者修改bin/elasticsearch,加上ES_JAVA_OPTS屬性:
?
1 ES_JAVA_OPTS="-Des.insecure.allow.root=true"保存之後重啟Elasticsearch。
