ElasticSearch外网访问9200端口

第一步、修改ElasticSearch根目录下的config文件夹下的elasticsearch.yml文件，如图

　　现在启动服务你会发现出现3个错误

elasticsearch 5.1 安装过程中遇到了一些问题做一些记录。

问题一：警告提示
[2016-12-20T22:37:28,543][INFO ][o.e.b.BootstrapCheck     ] [elk-node1] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks
[2016-12-20T22:37:28,552][ERROR][o.e.b.Bootstrap          ] [elk-node1] node validation exception
bootstrap checks failed
max number of threads [1024] for user [elasticsearch] is too low, increase to at least [2048]
[2016-12-20T22:37:28,560][INFO ][o.e.n.Node               ] [elk-node1] stopping ...
[2016-12-20T22:37:28,628][INFO ][o.e.n.Node               ] [elk-node1] stopped
[2016-12-20T22:37:28,629][INFO ][o.e.n.Node               ] [elk-node1] closing ...
[2016-12-20T22:37:28,677][INFO ][o.e.n.Node               ] [elk-node1] closed

报了一大串错误，其实只是一个警告。

解决：使用新的linux版本，就不会出现此类问题了。

问题二：ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]
解决：切换到root用户，编辑limits.conf 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

问题三：max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

解决：切换到root用户，进入limits.d目录下修改配置文件。
vi /etc/security/limits.d/90-nproc.conf
修改如下内容：

* 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]

解决：切换到root用户修改配置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。

然后在本机上输入本机ip:9200测试即可
