有几个与此问题类似的问题,例如:
Redis is configured to save RDB snapshots, but it is currently not able to persist on disk - Ubuntu Server
MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled
但是这些都不能解决我的问题。
问题是我在docker-compose中运行我的redis,只是无法理解如何在docker-compose启动时解决此问题。
redis docs说这是解决方法:
当Redis安装在docker之外时,这可以工作。但是如何使用docker-compose运行此命令?
我尝试了以下方法:
1)添加命令:
services:
cache:
image: redis:5-alpine
command: ["echo", "1", ">", "/proc/sys/vm/overcommit_memory", "&&", "redis-server"]
ports:
- ${COMPOSE_CACHE_PORT:-6379}:6379
volumes:
- cache:/data
这不起作用:
docker-compose up
Recreating constructor_cache_1 ... done
Attaching to constructor_cache_1
cache_1 | 1 > /proc/sys/vm/overcommit_memory && redis-server
constructor_cache_1 exited with code 0
2)挂载
/proc/sys/vm/
目录。失败:证明我无法挂载到/ proc /目录。
3)覆盖入口点:
custom-entrypoint.sh:
#!/bin/sh
set -e
echo 1 > /proc/sys/vm/overcommit_memory
# first arg is `-f` or `--some-option`
# or first arg is `something.conf`
if [ "${1#-}" != "$1" ] || [ "${1%.conf}" != "$1" ]; then
set -- redis-server "$@"
fi
# allow the container to be started with `--user`
if [ "$1" = 'redis-server' -a "$(id -u)" = '0' ]; then
find . \! -user redis -exec chown redis '{}' +
exec su-exec redis "$0" "$@"
fi
exec "$@"
docker-compose.yml:
services:
cache:
image: redis:5-alpine
ports:
- ${COMPOSE_CACHE_PORT:-6379}:6379
volumes:
- cache:/data
- ./.cache/custom-entrypoint.sh:/usr/local/bin/custom-entrypoint.sh
entrypoint: /usr/local/bin/custom-entrypoint.sh
这也行不通。
如何解决这个问题?
最佳答案
TL; DR 您的redis不安全
更新:
使用expose而不是ports
,以便该服务仅可用于链接的服务
原始答案:
长答案:
这可能是由于不安全的redis-server
实例所致。 Docker容器中的默认Redis镜像是不安全的。
我只用redis
就可以连接到我的Web服务器上的redis-cli -h <my-server-ip>
为了解决这个问题,我经历了this DigitalOcean article和许多其他事件,并能够关闭端口。
redis
部分更新为(相应地更新文件路径)redis:
restart: unless-stopped
image: redis:6.0-alpine
command: redis-server /usr/local/etc/redis/redis.conf
env_file:
- app/.env
volumes:
- redis:/data
- ./app/conf/redis.conf:/usr/local/etc/redis/redis.conf
ports:
- "6379:6379"
redis.conf
和command
中volumes
的路径应匹配redis-cli -h <my-server-ip>
进行验证(已停止为我工作)关于docker - docker:MISCONF Redis配置为保存RDB快照,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/60743175/
