1. Network configuration
1. Add temporary IP
ifconfig eth0 The first IP address netmask subnet mask up
ifconfig eth0:0 The second IP address netmask subnet mask up
2. Check whether the networkmanager service is started
[root@localhost ~]# systemctl status NetworkManager
uses graphical settings
[root@localhost ~]# nmtui
add modification delete save exit
[root@xuegod61 ~]# systemctl restart network restart service
3. Use command to modify IP
[root@xuegod61 ~]# vi / etc/sysconfig/network-scripts/ifcfg-eno16777736 //Network card configuration file
TYPE="Ethernet" BOOTPROTO
="static"
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes "
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"

Firewall settings [root@xuegod60 ~]# systemctl status firewalld. service # View status [root@xuegod60 ~]# systemctl stop firewalld #Temporary shutdown [root@xuegod60 ~]# systemctl disable firewalld #Automatic shutdown at startup Turn off selinux and set up automatic shutdown at startup //Temporary shutdown [root@xuegod60 ~]# setenforce 0 //Permanently close [root@xuegod60 ~]# vim /etc/sysconfig/selinux 3. The CD is automatically mounted
[root@xuegod60 ~]# echo "/dev/cdrom /mnt iso9660 defaults 0 0 " >> /etc/fstab //similar to vim /etc/fstab and then add
[root@xuegod60 ~]# mount -a / at the end of the file /View the mount
[root@xuegod60 ~]# df -Th //View the mount point
4. The configuration of the local YUM source
must first mount the local CD file (step 3, the mount point here is /mnt)
//View Configured yum source
[root@localhost ~]# ll /etc/yum.repos.d/
[root@localhost ~]# vim /etc/yum.repos.d/rhel.repo
[rhel7-server]
name= rhel7-server
baseurl=file:///mnt
enabled=1
gpgcheck=0
[root@localhost ~]# yum clean all #Empty yum cache
[root@localhost ~]# yum list #Generate cache list
//Ok
