系统性部署系统母盘【rhel7和rhel9】

rhel9版：

首先vim /usr/bin/vmset.sh   写入

#!/bin/bashifconfig $1 &> /dev/null || {echo "net device $1 is not exist"exit
}ping -c1 -w1 $2 &> /dev/null && {echo "$2 is exist"exit
}grep $1 -r /etc/NetworkManager/system-connections/ | awk -F : '{system("rm -fr $"1)}'cat >/etc/NetworkManager/system-connections/$1.nmconnection <<EOF
[connection]
id=$1
type=ethernet
interface-name=$1
[ipv4]
method=manual
address1=$2/24,172.25.254.2
dns=8.8.8.8
EOFchmod 600 /etc/NetworkManager/system-connections/$1.nmconnection
nmcli connection reload
nmcli connection up $1hostnamectl hostname $3grep -e "$2\t$3" /etc/hosts || {echo -e "$2\t$3" >> /etc/hosts
}

再添加执行权限 chmod +x /usr/bin/vmset.sh

接下来配置软件仓库

vim /etc/rc.d/rc.local进行挂载mount /dev/sr0 /rhel9

chmod +x etc/rc.d/rc.local

cd etc/yum.repos.d/

vim  rhel9.repo

写入

[AppStream]
name = AppStream
baseurl = file:///rhel9/AppStream
gpgcheck =0[BaseOS]
name = AppStream
baseurl = file:///rhel9/BaseOS
gpgcheck =0

mount  /dev/sr0  /rhel9/

dnf search nginx

检查是否成功

cd etc/NetworkManager/

cd system-connerctions/

rm -rf ens160.nmconnection

接下来临时解除 SELinux 的安全限制​​，以确保网络配置和主机名修改能够顺利完成

# 执行示例：为 eth0 配置 IP 192.168.1.100，主机名为 servera

./vmset.sh eth0 192.168.1.100 servera

rhel7版

vim /usr/bin/vmset.sh   写入

#!/bin/bashifconfig $1 &> /dev/null || {echo "net device $1 is not exist"exit
}ping -c1 -w1 $2 &> /dev/null && {echo "$2 is exist"exit
}grep $1 -r /etc/sysconfig/network-scripts/ | awk -F : '{system("rm -fr "$1)}'cat >/etc/sysconfig/network-scripts/ifcfg-$1 <<EOF
DEVICE=$1
NAME=$1
BOOTPROTO=none
IPADDR0=$2
PREFIX0=24
GATEWAY0=172.25.254.2
DNS1=8.8.8.8
ONBOOT=yes
EOFnmcli connection reload
nmcli connection up $1hostnamectl set-hostname $3grep -e "$2\t$3" /etc/hosts || echo -e "$2\t$3" >> /etc/hosts

再添加执行权限 chmod +x /usr/bin/vmset.sh

接下来配置软件仓库

vim /etc/rc.d/rc.local进行挂载mount /dev/sr0 /rhel9

chmod +x etc/rc.d/rc.local

cd etc/yum.repos.d/

vim  rhel7.repo

写入

[rhel7]
name = rhel7
baseurl = file:///rhel7
gpgcheck = 0

yum list nfs-utils查看是否成功

接下来删除没用的文件

cd /etc/sysconfig/network-scripts/

rm -fr ifcfg-ens33

接下来临时解除 SELinux 的安全限制​​，以确保网络配置和主机名修改能够顺利完成

执行如rhel9及可
