问题

docker安装并启动elasticsearch时内存不足

系统centos8(阿里云ecs服务器)

[root@iZ2zeczvvb79boy368xppwZ ~]# cat /etc/redhat-release
CentOS Linux release 8.1.1911 (Core)

安装过程

?
1
docker pull elasticsearch:6.4.0

修改虚拟机内存(貌似没有效果)

?
1
sysctl -w vm.max_map_count=262144

使用docker run命令跑容器

docker run -p 9200:9200 -p 9300:9300 --name elasticsearch \
-e "discovery.type=single-node" \
-e "cluster.name=elasticsearch" \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
-d elasticsearch:6.4.0

docker ps查看容器并没有启动

docker ps -a 查看容器确实创建了

查看日志docker logs -f elasticsearch命令查看日志发现jvm内存不足

[root@iZ2zeczvvb79boy368xppwZ ~]# docker logs -f elasticsearch
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00007ebf15330000, 549668585472, 0) failed; error='Not enough space' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 549668585472 bytes for committing reserved memory.

解决方法

修改jvm.options文件配置
首先查找jvm.options文件位置(每个服务器的位置可能不同)

?

[root@iZ2zeczvvb79boy368xppwZ ~]# find / -name jvm.options
/var/lib/docker/overlay2/d399872a3517b4d4acb0d2f70d0625c0f38251ffe5819a1cea00f8213de3e7f5/diff/usr/share/elasticsearch/config/jvm.options

vim进入文件修改虚拟机最小内存

?

[root@iZ2zeczvvb79boy368xppwZ ~]# vim /var/lib/docker/overlay2/d399872a3517b4d4acb0d2f70d0625c0f38251ffe5819a1cea00f8213de3e7f5/diff/usr/share/elasticsearch/config/jvm.options

找到-Xms属性,修改成512m(我的elasticsearch:6.4.0默认为1g)

## JVM configuration
 
################################################################
## IMPORTANT: JVM heap size
################################################################
##
## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
## for more information
##
################################################################
 
# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space
 
-Xms512m
-Xmx512m

保存并退出

vim中按i进入编辑模式,按ESC退出编辑模式,按:进入命令模式,然后在底部命令行输入w为保存,q为退出,q!为强制退出。
再次启动容器,docker ps查看容器启动成功
