在/etc/sysconfig/network-scripts/中新建文件ifcfg-eth0-range0
vi /etc/sysconfig/network-scripts/ifcfg-eth0-range0
#输入以下文件内容格式：

ONBOOT=yes
BOOTPROTO=static
IPADDR_START=起始IP地址

debian
编辑保存 vi /etc/network/ipboot.sh
以下不用配置主ip
for i in {195..222};do ip addr add 156.226.120.$i/27 dev eno1;done
for i in {226..254};do ip addr add 156.226.121.$i/27 dev eno1;done
for i in {2..30};do ip addr add 156.226.122.$i/27 dev eno1;done
for i in {34..62};do ip addr add 156.226.123.$i/27 dev eno1;done
for i in {66..94};do ip addr add 156.226.124.$i/27 dev eno1;done
for i in {98..126};do ip addr add 156.226.125.$i/27 dev eno1;done
for i in {130..158};do ip addr add 156.226.126.$i/27 dev eno1;done
for i in {162..190};do ip addr add 156.226.127.$i/27 dev eno1;done
编辑保存vi /etc/rc.local 复制以下
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. cd ./etc/network/ bash ipboot.sh exit 0
然后执行
chmod 777 /etc/network/ipboot.sh chmod 777 /etc/rc.local systemctl restart rc-local 然后重启 reboot
