ElasticSearch启动报错,常规解决方法

启动检查没有通过
[2017-07-30T13:54:23,964][INFO ][o.e.b.BootstrapChecks    ] [Z3aG6HQ] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks
ERROR: [2] bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

解决：

[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

编辑 /etc/security/limits.conf
在文件最后添加
* soft nofile 65536
* hard nofile 65536
保存

此文件修改后需要重新登录用户，才会生效

[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

1、切换到root用户修改配置sysctl.conf

3、并执行命令：
