Elasticsearch 启动报错参数配置处理 参数配置

1.elasticsearch-6.1.2的具体就不介绍了,详情可以去看Elasticsearch guide

2.为了主机可以访问虚拟机里的ES 开启外部访问

vi config/elasticsearch.yml
 
network.host: 0.0.0.0  #打开此注释,正式环境根据情况指定IP

3.启动elasticsearch报如下错误

./bin/elasticsearch -d

[2018-01-26T03:06:12,987][ERROR][o.e.b.Bootstrap ] [sA_Y-N7] node validation exception
[3] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max number of threads [3884] for user [hadoop] is too low, increase to at least [4096]
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

针对上述错误修改如下:

vi /etc/security/limits.conf
 
* soft nofile 65536
* hard nofile 65536
* soft nproc  4096
* hard nproc  4096
vi /etc/security/limits.d/20-nproc.conf
 
*          soft    nproc     4096
root       soft    nproc     unlimited
vi /etc/sysctl.conf
 
vm.max_map_count=655360

使其生效

sysctl -p

退出shell,重进生效,然后启动ok了

限制多个ip地址 第一个为本机器的内网IP
network.host: 10.181.28.41 10.181.30.11 10.181.30.15 10.181.30.21 10.181.30.51
