4. 配置

4.1 配置/etc/elasticsearch/elasticsearch.yml

vim /etc/elasticsearch/elasticsearch.yml 

取消註釋：node.name: node-1

修改網路和埠，取消註釋master節點，單機只保留一個node

4.2 配置 /etc/elasticsearch/config/jvm.options

vim /etc/elasticsearch/config/jvm.options
-Xms512m
-Xmx512m

4.3 配置sysctl.conf

# vim /etc/sysctl.conf
末尾新增：vm.max_map_count=655360

讓其生效
# sysctl -p

4.4 配置/etc/security/limits.conf

vim /etc/security/limits.conf
*               soft    nofile          65536
*               hard    nofile          65536
*               soft    nproc           4096
*               hard    nproc           4096
