Docker启动Redis容器时报错WARNING: The TCP backlog setting of 511 cannot be enforced

正常使用命令

docker pull redis

之后启动        

docker run --name m-redis -p 8379:6379 -v /data/redis/redis.conf:/usr/local/etc/redis/redis.conf -d redis

发现容器并没有启动，于是查看了一下logs 

[root@localhost redis]# docker logs m-redis
1:C 25 Sep 2023 04:03:47.852 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

下意识得修改了宿主机的 /proc/sys/net/core/somaxconn 文件

echo 511 > /proc/sys/net/core/somaxconn

发现并没有什么卵用。考虑是镜像内的文件， 于是修改创建容器命令为

docker run -p 8379:6379 --name m-redis \
--sysctl net.core.somaxconn=1024 \
-v /data/docker/m-redis/data:/data \
-v /data/docker/m-redis/conf/redis.conf:/usr/local/etc/redis/redis.conf \
-e TIME_ZONE="Asia/Shanghai" \
-e TZ="Asia/Shanghai" \
-d --restart=always \
--privileged=true \
redis

docker ps 查看解决问题了

[root@localhost redis]# docker ps
