    sysctl命令用于运行时配置内核参数,这些参数位于/proc/sys/目录,可以使用sysctl修改系统变量,也可以通过编辑/etc/sysctl.conf文件来修改系统变量。

    sysctl (选项) (参数)
    选项
    -n:打印值时不打印关键字;
    -e:忽略未知关键字错误;
    -N:仅打印名称;
    -w:当改变sysctl设置时使用此项;
    -p:从配置文件“/etc/sysctl.conf”加载内核参数设置;
    -a:打印当前所有可用的内核参数变量和值;
    -A:以表格方式打印当前所有可用的内核参数变量和值。
    参数
    变量=值:设置内核参数对应的变量值。sysctl变量的设置通常是字符串、数字或者布尔型。

    临时改变某个系统参数的值,如果系统重启,或执行了 service network restart命令,所设置的值即会丢失。例如想启用IP路由转发功能,

    #echo 1 > /proc/sys/net/ipv4/ip_forward

    或者

    #sysctl -w net.ipv4.ip_forward=1

    永久保留配置,可以修改/etc/sysctl.conf文件,并重新加载系统参数sysctl -p

    net.ipv4.ip_forward=1

    Sysctl命令用来配置与显示在/proc/sys目录中的内核参数。如果想使参数长期保存,可以通过编辑/etc/sysctl.conf文件来实现。

    命令格式

    名字
           sysctl - 在运行时配置内核参数
    
    语法
           sysctl [options] [variable[=value]] [...]
           sysctl -p [file or regexp] [...]
    
    描述
           sysctl 可以在运行时配置内核参数。所有可用参数都位于 /proc/sys/ 目录下。
    
    参数与选项
           variable
                  要读取其值的变量,比如"kernel.ostype"。[提示]"."也可以用"/"代替。
    
           variable=value
                  要设置变量及相应的值。必须同时使用 -w 选项。
                  如果值中含有特殊意义的shell字符或引号,那么你最好使用双引号进行界定。
    
           -n, --values
                  显示变量值的同时不显示变量名
    
           -e, --ignore
                  忽略不正确的变量名而不报错
    
           -N, --names
                  仅显示变量名。常用于脚本中。
    
           -q, --quiet
                  不在 stdout 上显示变量值
    
           -w, --write
                  如果你想修改变量的值,就必须使用此选项
    
           -p[FILE], --load[=FILE]
                  从指定文件(默认 /etc/sysctl.conf)中加载已经设置好的一系列变量值。
                  如果使用 - 作为文件名,那么表示从 stdin 读取配置。
                  FILE 还可以是一个正则表达式,以匹配多个文件。
    
           -a, --all
                  显示所有当前的变量名
    
           --deprecated
                  在 --all 的输出中包含已被反对使用的参数
    
           -b, --binary
                  打印值时不添加换行标记
    
           --system
                  从所有下列配置文件中加载系统设置
                  /run/sysctl.d/*.conf
                  /etc/sysctl.d/*.conf
                  /usr/local/lib/sysctl.d/*.conf
                  /usr/lib/sysctl.d/*.conf
                  /lib/sysctl.d/*.conf
                  /etc/sysctl.conf
    
           -r, --pattern pattern
                  仅应用与正则表达式匹配的文件中的设置。
    
           -h, --help
                  显示帮助信息后退出
    
           -V, --version
                  显示版本信息后退出
    例:

    # echo 1 > /proc/sys/net/ipv4/ip_forward
    # 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

    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 <filename> (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
