elasticsearch-5.1.1 安装的问题

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:使用心得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。
