docker安裝elasticsearch內存修改

用docker 安裝的elasticsearch默認堆內存最大設置的2G或者1G

可以通過如下方法修改

[root@nova-92 logs]# find /var/lib/docker/ -name jvm.options

/var/lib/docker/overlay2/f394fa1197ace3d592bb37738b95335fc722950c6a39167a0106586f0d2f2382/diff/etc/elasticsearch/jvm.options
/var/lib/docker/overlay2/1bda3723143784e9db1324180f741dc2532addf41f9224248ade99964966cf18/merged/etc/elasticsearch/jvm.options

 

然后 vim /var/lib/docker/overlay2/f394fa1197ace3d592bb37738b95335fc722950c6a39167a0106586f0d2f2382/diff/etc/elasticsearch/jvm.options

 

修改里面

-Xms4g
-Xmx4g

 

然后保存，

 

然后重啟docker 里的 elasticsearch 容器

docker restart elasticsearch
