Linux上最大套接字数

Question

似乎服务器限制在~32720个套接字......我已经尝试了每个已知的变量来提高这个限制.但服务器仍然限制在32720打开套接字,即使仍然有4Go的空闲内存和80%的空闲cpu ...

这是配置

net.netfilter.nf_conntrack_max = 999999
net.ipv4.netfilter.ip_conntrack_max = 999999
net.nf_conntrack_max = 999999

有什么想法吗 ？

如果您正在处理openssl和线程，请检查/ proc / sys / vm / max_map_count并尝试提高它。
