1.sysctl 命令

         功能：用于在内核运行时动态地修改内核的运行参数，可用的内核参数在目录“/proc/sys”

         特点：它包含一些TCP/ip堆栈和虚拟内存系统的高级选项，用sysctl可以读取设置超过五百个系统变量。

         参数生效：sysctl命令对内核参数的修改仅在当前生效，重启系统后参数丢失。参数永久生效可以修改配置文件“/etc/sysctl.conf”。

 2.sysctl 命令使用规范

1.语法：
    sysctl(选项)(参数)
    
2.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。
    
3.参数
    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。（布尔型用 1 来表示'yes'，用 0 来表示'no'）。

4.修改变量的情况
1）临时改变某个指定参数的值：
    sysctl -w key=values
2）永久生效：
    vim /etc/sysctl.conf
        key=values
    :wq

5.任何修改，都需要执行以下操作，使其不关机下生效：
    /sbin/sysctl -p
    /sbin/sysctl -w net.ipv4.route.flush=1
 

3.sysctl 案例

1.查看所有可读变量：
    sysctl -a
2. 读取指定的一个变量
    sysctl net.netfilter.nf_conntrack_helper
    net.netfilter.nf_conntrack_helper = 1
3.修改指定变量的值
    sysctl net.ipv6.neigh.lo.locktime=1
    net.ipv6.neigh.lo.locktime = 1

4.屏蔽别人 ping 你的主机，则加入以下代码：
    vim /etc/sysctl.conf
    net.ipv4.icmp_echo_ignore_all = 1

5.启用IP路由转发功能，临时生效
    sysctl -w net.ipv4.ip_forward=1
    或者
    echo 1 > /proc/sys/net/ipv4/ip_forward
 

4、内核参数解析

重要参数解析：待整理完善

fs.file-max = 999999：这个参数表示进程（比如一个worker进程）可以同时打开的最大句柄数，这个参数直线限制最大并发连接数，需根据实际情况配置。
net.ipv4.tcp_max_tw_buckets = 6000 #这个参数表示操作系统允许TIME_WAIT套接字数量的最大值，如果超过这个数字，TIME_WAIT套接字将立刻被清除并打印警告信息。该参数默认为180000，过多的TIME_WAIT套接字会使Web服务器变慢。
注意：主动关闭连接的服务端会产生TIME_WAIT状态的连接
net.ipv4.ip_local_port_range = 1024 65000 #允许系统打开的端口范围。
net.ipv4.tcp_tw_recycle = 1 #启用timewait快速回收。和下面这个是一对
net.ipv4.tcp_tw_reuse = 1 #开启重用。允许将TIME-WAIT 
sockets重新用于新的TCP连接。这对于服务器来说很有意义，因为服务器上总会有大量TIME-WAIT状态的连接。
net.ipv4.tcp_keepalive_time = 30：这个参数表示当keepalive启用时，TCP发送keepalive消息的频度。默认是2小时，若将其设置的小一些，可以更快地清理无效的连接（不是说的软件keepalive，是比如nginx的 keepalive参数）。
net.ipv4.tcp_syncookies = 1 #开启SYN Cookies，当出现SYN等待队列溢出时，启用cookies来处理。
net.core.somaxconn = 40960 #web 应用中 listen 函数的 backlog 默认会给我们内核参数的 net.core.somaxconn 限制到128，而nginx定义的NGX_LISTEN_BACKLOG 默认为511，所以有必要调整这个值。
注：对于一个TCP连接，Server与Client需要通过三次握手来建立网络连接.当三次握手成功后,我们可以看到端口的状态由LISTEN转变为ESTABLISHED,接着这条链路上就可以开始传送数据了.每一个处于监听(Listen)状态的端口,都有自己的监听队列.监听队列的长度与如somaxconn参数和使用该端口的程序中listen()函数有关；   somaxconn参数:定义了系统中每一个端口最大的监听队列的长度,这是个全局的参数,默认值为128，对于一个经常处理新连接的高负载 web服务环境来说，默认的 128 太小了。大多数环境这个值建议增加到 1024 或者更多。大的侦听队列对防止拒绝服务 DoS 攻击也会有所帮助。
net.core.netdev_max_backlog = 262144 #每个网络接口接收数据包的速率比内核处理这些包的速率快时，允许送到队列的数据包的最大数目。
net.ipv4.tcp_max_syn_backlog = 262144#这个参数标示TCP三次握手建立阶段接受SYN请求队列的最大长度，默认为1024，将其设置得大一些可以使出现Nginx繁忙来不及accept新连接的情况时，Linux不至于丢失客户端发起的连接请求。
net.ipv4.tcp_rmem = 10240  87380  12582912#这个参数定义了TCP接受缓存（用于TCP接受滑动窗口）的最小值、默认值、最大值。
net.ipv4.tcp_wmem = 10240 87380 12582912：这个参数定义了TCP发送缓存（用于TCP发送滑动窗口）的最小值、默认值、最大值。
net.core.rmem_default = 6291456：这个参数表示内核套接字接受缓存区默认的大小。
net.core.wmem_default = 6291456：这个参数表示内核套接字发送缓存区默认的大小。
net.core.rmem_max = 12582912：这个参数表示内核套接字接受缓存区的最大大小。
net.core.wmem_max = 12582912：这个参数表示内核套接字发送缓存区的最大大小。
net.ipv4.tcp_syncookies = 1：该参数与性能无关，用于解决TCP的SYN攻击。
 

5.内存的参数优化：

s.aio-max-nr = 65536    # io读写参数
fs.file-max = 6553600    # 最大打开文件数
kernel.shmall = 18446744073692774399    # 共享内存参数
kernel.shmmax = 18446744073692774399    # 共享内存参数最大值
kernel.shmmni = 4096    # 共享内存参数最小值
kernel.sem = 250 32000 32 128#
net.ipv4.ip_local_port_range = 32768    60999    # 本机允许对外的端口映射范围
net.core.rmem_default = 262144    # 接收套接字缓冲区大小的默认值(以字节为单位)
net.core.rmem_max = 4194304        # 接收套接字缓冲区大小的最大值(以字节为单位)
net.core.wmem_default = 262144    # 发送套接字缓冲区大小的最大值(以字节为单位)。
net.core.wmem_max = 1048586        # 用来限制监听(LISTEN)队列最大数据包的数量，超过这个数量就会导致链接超时或者触发重传机制
