centos7查看端口状态 centos74查看端口

关于centos7查看端口状态，centos7.4查看端口这个很多人还不知道，今天小周来为大家解答以上的问题，现在让我们一起来看看吧！

1、SELinux status: enabled上一共配置了两张万兆两口的网卡和一张千兆四口的网卡，其中不同万兆卡上，两端口做Bonding，同时千兆卡上也挑了间隔的两口做Bonding，大概如下情况：、Policy MLS status: enabled0,1,2,3千兆端口，4,5,6,7是万兆端口，这时经常紊乱是3,4的端口，两端口变更，使得做了bonding的端口无法生效CentOS7的端口命名规则a.编辑文件vi /etc/sysconfig/grubGRUB_TIMEOUT=5GRUB_DEFAULT=sedGRUB_DISABLE_SUBMENU=trueGRUB_TERMINAL_OUTPUT="console"GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 net.ifnames=0 biosdevname=0 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet"GRUB_DISABLE_RECOVERY="true"“以上标红色的值是修改为的基础”b.执行命令生效grub2-mkconfig -o /boot/grub2/grub.cfgc.增加规划文件vi /etc/udev/rules.d/70-persistent-net.rulesSUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="78:2b:cb:xx:xx:01", ATTR{type}=="1", KERNEL=="", NAME="0"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="78:2b:cb:xx:xx:02", ATTR{type}=="1", KERNEL=="", NAME="1"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="78:2b:cb:xx:xx:03", ATTR{type}=="1", KERNEL=="", NAME="2"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="78:2b:cb:xx:xx:04", ATTR{type}=="1", KERNEL=="", NAME="3"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="00:1b:21:xx:xx:a1", ATTR{type}=="1", KERNEL=="", NAME="4"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="00:1b:21:xx:xx:a0", ATTR{type}=="1", KERNEL=="", NAME="5"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="00:60:6e:xx:xx:f6", ATTR{type}=="1", KERNEL=="", NAME="6"SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="00:60:6e:xx:xx:f7", ATTR{type}=="1", KERNEL=="", NAME="7"。
