CentOS 9 Stream的固定IP配置

HostName="hbase01"
NetworkConfPath="/etc/NetworkManager/system-connections"
NetCardName=$(ip a | grep "2: e" | grep -oE "e.*(n*).*:")
NetCardName=$(echo  ${NetCardName%*:})

IPV4MD="121"
IPV4ED="139"
IPV4="${IPV4ST}.${IPV4MD}.${IPV4ED}"
GatwayED="2"
Gatway="${IPV4ST}.${IPV4MD}.${GatwayED}"
Address1="${IPV4}/${Gatway}"
DNS1="114.114.114.114"
Possition1="\[ipv4\]"
Label1="address1="
Label2="DNS="

sed -i "/${Possition1}/a${Label1}${Address1}" ${NetworkConfFilePath}
sed -i "/${Possition1}/a${Label2}${Address1}" ${NetworkConfFilePath}
sed -i "/uuidn=/cuuidn=`uuidgen`" ${NetworkConfFilePath}

nmcli c reload
nmcli c up ens33

hostnamectl set-hostname $HostName

在hbase01上克隆两台虚拟机
vi /root/test.sh
chmod +x /root/test.sh
