问题一:

  [2016-11-06T16:27:21,712][WARN ][o.e.b.JNANatives ] unable to install syscall filter:   Java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMPandCONFIG_SECCOMP_FILTERcompiledinatorg.elasticsearch.bootstrap.Seccomp.linuxImpl(Seccomp.java:349) ~[elasticsearch-5.0.0.jar:5.0.0]   at org.elasticsearch.bootstrap.Seccomp.init(Seccomp.java:630) ~[elasticsearch-5.0.0.jar:5.0.0]   原因:报了一大串错误,大家不必惊慌,其实只是一个警告,主要是因为你Linux版本过低造成的。   解决方案: 1、重新安装新版本的Linux系统 2、警告不影响使用,可以忽略   问题二: ERROR: bootstrap checks failed   max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]   原因:无法创建本地文件问题,用户最大可创建文件数太小   解决方案: 切换到root用户,编辑limits.conf配置文件, 添加类似如下内容:   vi /etc/security/limits.conf   添加如下内容: *  soft nofile 65536   * hard nofile 131072   * soft nproc 2048   * hard nproc 4096 备注:* 代表Linux所有用户名称(比如 hadoop)   保存、退出、重新登录才可生效   问题三: max number of threads [1024] for user [es] likely too low, increase to at least [2048] 原因:无法创建本地线程问题,用户最大可创建线程数太小 解决方案:切换到root用户,进入limits.d目录下,修改90-nproc.conf 配置文件。   vi /etc/security/limits.d/90-nproc.conf   找到如下内容:   * soft nproc 1024   #修改为   * soft nproc 2048   问题四: max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144] 原因:最大虚拟内存太小 解决方案:切换到root用户下,修改配置文件sysctl.conf   vi /etc/sysctl.conf   添加下面配置:   vm.max_map_count=655360   并执行命令:   sysctl -p   然后重新启动elasticsearch,即可启动成功。   问题五: ElasticSearch启动找不到主机或路由 原因:ElasticSearch 单播配置有问题 解决方案: 检查ElasticSearch中的配置文件 vi  config/elasticsearch.yml 找到如下配置:   discovery.zen.ping.unicast.hosts:["192.168.**.**:9300","192.168.**.**:9300"] 一般情况下,是这里配置有问题,注意书写格式   问题六: org.elasticsearch.transport.RemoteTransportException: Failed to deserialize exception response from stream   原因:ElasticSearch节点之间的jdk版本不一致   解决方案:ElasticSearch集群统一jdk环境   问题七: Unsupported major.minor version 52.0   原因:jdk版本问题太低 解决方案:更换jdk版本,ElasticSearch5.0.0支持jdk1.8.0   问题八: bin/elasticsearch-plugin install license ERROR: Unknown plugin license   原因:ElasticSearch5.0.0以后插件命令已经改变 解决方案:使用最新命令安装所有插件

bin/elasticsearch-plugin install x-pack

 问题九:
