docker安装elasticsearch报错AccessDeniedException:/tmp/elasticsearch的解决

docker安装elasticsearch报错

按照elasticsearch的官方文档用docker安装7.7.1版本的es,报错

(顺带说以下，如果我把镜像的版本换成最新的7.12.1，不会报错。用7.7.1的就会报错）

[root@webapi4-app-22-151 workspace]# docker run -p 9200:9200 -p 9300:9300 -e “discovery.type=single-node” docker.elastic.co/elasticsearch/elasticsearch:7.7.1

大概搜了下这个问题,别人的报错都是/usr/share/elasticsearch目录,而我的是/tmp目录,不太一样.

我用别人的解决方法

• 设置环境变量TAKE_FILE_OWNERSHIP=true
• 容器内chown -R 1000:0 /usr/share/elasticsearch/{data,logs}
• 把宿主机的挂载目录权限设置成777

这三种办法不管用,还是报错,所以,使出绝招,进入容器里面排错.

启动一个临时容器,默认执行命令/bin/bash

默认执行命令变成了/bin/bash,而不是docker-entrypoint.sh,容器主进程是/bin/bash所以容器不会遇到错误导致退出

[root@webapi4-app-22-151 workspace]# docker run -itd -e “discovery.type=single-node” docker.elastic.co/elasticsearch/elasticsearch:7.7.1 /bin/bash
5f733625a5808d15c8895cb12ddf94845f5f1b57960edd1d224544cf8da08bab
[root@webapi4-app-22-151 workspace]# docker exec -it 5f7 bash
[root@5f733625a580 elasticsearch]#
#执行es容器的启动脚本,报错
[root@5f733625a580 elasticsearch]# sh /usr/local/bin/docker-entrypoint.sh

就是出现的这个错误，/tmp目录

然后在容器里给/tmp目录授权777，重新执行脚本

[root@5f733625a580 elasticsearch]# chmod 777 /tmp
[root@5f733625a580 elasticsearch]# sh /usr/local/bin/docker-entrypoint.sh

报了新的错误

Error opening log file ‘logs/gc.log’: Permission denied

给容器内的/usr/share/elasticsearch目录设置权限

[root@5f733625a580 elasticsearch]# chown -R 1000:0 /usr/share/elasticsearch/
[root@5f733625a580 elasticsearch]# sh /usr/local/bin/docker-entrypoint.sh

最后elasticsearch服务启动成功

总结: 先配置

chmod 777 /tmp
chown -R 1000:0 /usr/share/elasticsearch/

这两条命令再执行脚本docker-entrypoint.sh

解决问题后

使用docker-compose安装，docker-compose.yml:

version: '2'
services:
  es:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.7.1
    container_name: es
    ports:
    - 9200:9200
    environment:
    - discovery.type=single-node
    - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
    - /data/elk/es/data:/usr/share/elasticsearch/data
    command:
    - /bin/bash 
    - -c 
    - |  
        chmod 777 /tmp
        chown -R 1000:0 /usr/share/elasticsearch/
        sh /usr/local/bin/docker-entrypoint.sh

启动成功

[root@webapi4-app-22-151 workspace]# docker-compose up -d
Creating es … done
[root@webapi4-app-22-151 workspace]# docker ps

目前暂时解决了这个问题，但是应该有更优的解决方法

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
