問(wèn)題
docker安裝并啟動(dòng)elasticsearch時(shí)內(nèi)存不足
系統(tǒng)centos8（阿里云ecs服務(wù)器）
[root@iZ2zeczvvb79boy368xppwZ ~]# cat /etc/redhat-release CentOS Linux release 8.1.1911 (Core)
安裝過(guò)程
docker pull elasticsearch:6.4.0
修改虛擬機(jī)內(nèi)存（貌似沒(méi)有效果）
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查看容器并沒(méi)有啟動(dòng)
[root@iZ2zeczvvb79boy368xppwZ ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES edfc400862eb rabbitmq:3.7.15 "docker-entrypoint.s…" 14 hours ago Up 14 hours 0.0.0.0:4369->4369/tcp, 0.0.0.0:5671-5672->5671-5672/tcp, 0.0.0.0:15671-15672->15671-15672/tcp, 0.0.0.0:25672->25672/tcp rabbitmq 2ae2f3f8dc1f nginx:1.10 "nginx -g 'daemon of…" 2 weeks ago Up 2 weeks 0.0.0.0:80->80/tcp, 443/tcp nginx 164e4e7561df redis:3.2 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:6379->6379/tcp redis eeabe57f1f21 mysql:5.7 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:3306->3306/tcp, 33060/tcp mysql
docker ps -a 查看容器確實(shí)創(chuàng)建了
[root@iZ2zeczvvb79boy368xppwZ ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 767829ae1d7c elasticsearch:6.4.0 "/usr/local/bin/dock…" About a minute ago Exited (1) About a minute ago elasticsearch edfc400862eb rabbitmq:3.7.15 "docker-entrypoint.s…" 14 hours ago Up 14 hours 0.0.0.0:4369->4369/tcp, 0.0.0.0:5671-5672->5671-5672/tcp, 0.0.0.0:15671-15672->15671-15672/tcp, 0.0.0.0:25672->25672/tcp rabbitmq 2ae2f3f8dc1f nginx:1.10 "nginx -g 'daemon of…" 2 weeks ago Up 2 weeks 0.0.0.0:80->80/tcp, 443/tcp nginx 164e4e7561df redis:3.2 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:6379->6379/tcp redis eeabe57f1f21 mysql:5.7 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:3306->3306/tcp, 33060/tcp mysql
查看日志docker logs -f elasticsearch命令查看日志發(fā)現(xiàn)jvm內(nèi)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. # An error report file with more information is saved as: # logs/hs_err_pid1.log
解決方法
修改jvm.options文件配置
首先查找jvm.options文件位置（每個(gè)服務(wù)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進(jìn)入文件修改虛擬機(jī)最小內(nèi)存
[root@iZ2zeczvvb79boy368xppwZ ~]# vim /var/lib/docker/overlay2/d399872a3517b4d4acb0d2f70d0625c0f38251ffe5819a1cea00f8213de3e7f5/diff/usr/share/elasticsearch/config/jvm.options
找到-Xms屬性，修改成512m（我的elasticsearch:6.4.0默認(rèn)為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進(jìn)入編輯模式，按ESC退出編輯模式，按：進(jìn)入命令模式，然后在底部命令行輸入w為保存，q為退出，q!為強(qiáng)制退出。
再次啟動(dòng)容器，docker ps查看容器啟動(dòng)成功
[root@iZ2zeczvvb79boy368xppwZ ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f5c4ed61196b elasticsearch:6.4.0 "/usr/local/bin/dock…" 15 minutes ago Up 15 minutes 0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp elasticsearch edfc400862eb rabbitmq:3.7.15 "docker-entrypoint.s…" 15 hours ago Up 15 hours 0.0.0.0:4369->4369/tcp, 0.0.0.0:5671-5672->5671-5672/tcp, 0.0.0.0:15671-15672->15671-15672/tcp, 0.0.0.0:25672->25672/tcp rabbitmq 2ae2f3f8dc1f nginx:1.10 "nginx -g 'daemon of…" 2 weeks ago Up 2 weeks 0.0.0.0:80->80/tcp, 443/tcp nginx 164e4e7561df redis:3.2 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:6379->6379/tcp redis eeabe57f1f21 mysql:5.7 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:3306->3306/tcp, 33060/tcp mysql
