本文介绍了解决Redis警告中提到的TCP backlog设置问题的方法。通过修改内核参数net.core.somaxconn为2048来提高服务负载能力。

Redis WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

 

内核参数默认128，对于负载很大的服务是不够的。改为2048或者更大

echo 2048 >   /proc/sys/net/core/somaxconn    系统重启后失效

vi /etc/sysctl.conf

net.core.somaxconn = 2048

保存，然后

sysctl -p

启动redis会有如下WARNING 对一个高负载的环境来说tcp设置128这个值，太小了。 想要永久解决该问题， 首先需要关闭redis，然后打开/etc/sysctl.conf sudo vim /etc/sysctl.conf 然后再最后加上net.core.somaxconn= 1024 如图： 之后再执行如下指令sudo sysctl -p进行更新。 再重启redis就可以解决了！ 关于如何重启redis请参考我本篇文章： https://blog.youkuaiyun.com/changyana/ar

下意识得修改了宿主机的 /proc/sys/net/core/somaxconn 文件。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。发现容器并没有启动，于是查看了一下logs。docker ps 查看解决问题了。
