sysctl命令用于运行时配置内核参数，这些参数位于/proc/sys目录下。sysctl配置与显示在/proc/sys目录中的内核参数．可以用sysctl来设置或重新设置联网功能，如IP转发、IP碎片去除以及源路由检查等。用户只需要编辑/etc/sysctl.conf文件，即可手工或自动执行由sysctl控制的功能。 命令格式： sysctl [-n] [-e] -w variable=value sysctl [-n] [-e] -p (default /etc/sysctl.conf) sysctl [-n] [-e] -a 常用参数的意义： -w 临时改变某个指定参数的值，如 sysctl -w net.ipv4.ip_forward=1 -a 显示所有的系统参数 -p 从指定的文件加载系统参数，如不指定即从/etc/sysctl.conf中加载 如果仅仅是想临时改变某个系统参数的值，可以用两种方法来实现,例如想启用IP路由转发功能： 1) #echo 1 > /proc/sys/net/ipv4/ip_forward 2) #sysctl -w net.ipv4.ip_forward=1 以上两种方法都可能立即开启路由功能，但如果系统重启，或执行了 # service network restart 命令，所设置的值即会丢失，如果想永久保留配置，可以修改/etc/sysctl.conf文件 将 net.ipv4.ip_forward=0改为net.ipv4.ip_forward=1 1, sysctl命令的作用 在运行时配置内核参数 2,用法举例: -w 用此选项来改变一个sysctl设置 例:sysctl -w net.ipv4.ip_forward=1 -p 载入sysctl配置文件 如-p后未指定路径，则载入 /etc/sysctl.conf 例: sysctl -p /etc/sysctl.conf 001 了解这些内核参数的意义对于解决问题会很有帮助。 002 sh-# sysctl -a 003 kernel.sched_child_runs_first = 0 004 kernel.sched_min_granularity_ns = 750000 005
