1.设置

/etc/security/limits.conf

/etc/sysctl.conf

linux 修改端口范围

echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range

客户端

net.ipv4.tcp_mem = 262144 524288 786432 net.ipv4.tcp_wmem = 1024 1024 2048 net.ipv4.tcp_rmem = 1024 1024 2048 fs.file-max = 1048576 net.ipv4.tcp_max_orphans = 16384

服务端

net.ipv4.tcp_mem = 252144 524288 786432 net.ipv4.tcp_wmem = 1024 1024 2048 net.ipv4.tcp_rmem = 1024 1024 2048 fs.file-max = 1048576 net.nf_conntrack_max = 1048576 net.netfilter.nf_conntrack_tcp_timeout_established = 1200

sudo modprobe ip_conntrack

然后sysctl -p

其他命令：

dmesg
