【问题描述】:
我尝试设置 Linux 内核。编辑 /etc/sysctl.conf 并执行sysctl -p
它显示错误
Invalid argument" setting key "net.core.somaxconn"
Linux 发行版:Ubuntu 12.04.4 LTS、x86_64、3.2.0-60-generic
$ cat /etc/sysctl.conf
net.ipv4.conf.eth0.arp_notify = 1
vm.swappiness = 0
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096 16384 4194304
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.core.somaxconn = 262144
net.core.netdev_max_backlog = 262144
fs.file-max = 1048576
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 1200
net.ipv4.tcp_max_syn_backlog = 409600
net.ipv4.ip_local_port_range = 1024 65000
net.ipv4.tcp_max_orphans = 262144
我可以将net.core.somaxconn 增加到262144 吗?
