#### 内核参数的优化，主要是在Linux系统中针对Nginx应用而进行的系统内核参数优化，常见的优化参数值如下。 下面给出一个优化实例以供参考: net.ipv4.tcp_max_tw_buckets = 6000 net.ipv4.ip_local_port_range = 1024 65000 net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_syncookies = 1 net.core.somaxconn = 262144 net.core.netdev_max_backlog = 262144 net.ipv4.tcp_max_orphans = 262144 net.ipv4.tcp\_max\_syn\_backlog = 262144 net.ipv4.tcp\_synack\_retries = 1 net.ipv4.tcp\_syn\_retries = 1 net.ipv4.tcp_fin\_timeout = 1 net.ipv4.tcp_keepalive_time = 30 将上面的内核参数值加入/etc/sysctl.conf文件中，然后执行如下命令使之生效: \[root@ localhost home\]#/sbin/sysctl -p
