1.故障现象:
阿里云ECS服务器:Welcome to Ubuntu 22.04.2 LTS (GNU/Linux 5.15.0-73-generic x86_64)
上用docker部署elasticsearch服务。
因为偷懒直接用的 snap软件包管理器安装的docker。安装docker的版本信息为:
部署es或者redis等服务时,发现用docker挂载一直比较奇怪。要么是报错:
docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/data/redis/conf/redis.conf" to rootfs at "/etc/redis/redis.conf": mount /data/redis/conf/redis.conf:/etc/redis/redis.conf (via /proc/self/fd/6), flags: 0x5000: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type
大概意思是:把文件/data/redis/conf/redis.conf挂载到目录上 /etc/redis/redis.conf
docker把挂载文件解析成了目录(/etc/redis/redis.conf),或者反向:把/data/redis/conf/redis.conf 解析成目录,/etc/redis/redis.conf解析成文件。所以报错,目录不能挂载到文件上。
要么是elasticsearch启动时报错:

另附运行脚本:
docker run -d --name es -e "ES_JAVA_OPTS=-Xms4096m -Xmx4096m" -e "discovery.type=single-node" -v /data/elasticsearch/data:/usr/share/elasticsearch/data:rw -v /data/elasticsearch/plugins:/usr/share/elasticsearch/plugins:rw --privileged -p 9200:9200 -p 9300:9300 elasticsearch:6.4.3
2. 问题解决:
百度后做过各种尝试都没成功:
- /data/elasticsearch/data 修改目录权限 777
- 关闭 selinux
- 将挂载文件 改为挂载目录
各种尝试都失败后怀疑是es版本问题。修改es版本后结果问题依旧。文章来源:https://www.toymoban.com/news/detail-719714.html
最终解决:找了个其他环境的docker版本:23.0.2 【问题解决】文章来源地址https://www.toymoban.com/news/detail-719714.html
