试了以上方法，然而并没有什么卵用！

试了以下终极方法：

查看端口监听：

[donald@testDesktop]$netstat-ntlp

(Notallprocessescouldbeidentified,non-ownedprocessinfo

willnotbeshown,youwouldhavetoberoottoseeitall.)

ActiveInternetconnections(onlyservers)

ProtoRecv-QSend-QLocalAddressForeignAddressStatePID/Programname

tcp00192.168.122.1:530.0.0.0:*LISTEN-

tcp000.0.0.0:220.0.0.0:*LISTEN-

tcp00127.0.0.1:6310.0.0.0:*LISTEN-

tcp600:::3306:::*LISTEN-

tcp600:::22:::*LISTEN-

tcp6在监控

[donald@testDesktop]$sudovim/etc/default/grub

修改如下

GRUB_TIMEOUT=5

GRUB_DEFAULT=saved

GRUB_DISABLE_SUBMENU=true

GRUB_TERMINAL_OUTPUT="console"

GRUB_CMDLINE_LINUX="ipv6.disable=1rd.lvm.lv=centos/rootrd.lvm.lv=centos/swapcrashkernel=autorhgbquiet"

GRUB_DISABLE_RECOVERY="true"

编译

[donald@testDesktop]$sudogrub2-mkconfig-o/boot/grub2/grup.cfg

重启

[donald@testDesktop]$reboot

再次查看端口：

[donald@testDesktop]$netstat-ntlp

(Notallprocessescouldbeidentified,non-ownedprocessinfo

willnotbeshown,youwouldhavetoberoottoseeitall.)

ActiveInternetconnections(onlyservers)

ProtoRecv-QSend-QLocalAddressForeignAddressStatePID/Programname

然并卵。。。。。。。。。。。
