1.不能用root启动
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root
解决办法参照：http://blog.csdn.net/lahand/article/details/78954112
2.启动出现警告
java.lang.UnsupportedOperationException: seccomp unavailable: CONFIG_SECCOMP not compiled into kernel, CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER are needed
解决办法：在elasticsearch.yml文件中 添加
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
