This article shows you how to install centos7 in vmware14. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

In general, you can minimize the installation, if you need to install Oracle, WebLogic and so on, select "GNOME Desktop", otherwise it is very difficult to install.

How to connect to the Internet

The default Nic is not active.

Modify the file / etc/sysconfig/network-scripts/ifcfg-ens33 (where ens33 is random, but all start with en) and change ONBOOT=no to ONBOOT=yes.

# modify this item to access the Internet # ONBOOT=noONBOOT=yesDNS1=202.101.224.68DNS2=202.101.224.69# if you need to specify IP, you also need to modify or add the following configuration, and change the network of the virtual machine to bridge mode. # BOOTPROTO=dhcpBOOTPROTO=staticGATEWAY=192.168.0.1IPADDR=192.168.0.240NETMASK=255.255.255.0

Then run systemctl restart network to restart the network card and you can surf the Internet. You can use the ping command to check.

You can also use ip addr to view the configuration of the network card. The ifconfig command cannot be used at this time because the installation is minimized.

Install the yum source

Use the yum source of 163s. Http://mirrors.163.com/

There is no wget command for minimizing installation, use the curl command instead.

Mv / etc/yum.repos.d/CentOS-Base.repo / etc/yum.repos.d/CentOS-Base.repo.backup#wget-O / etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repocurl-o / etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repoyum clean allyum makecache installs common software # downloads software Yum install wget# Editor yum install vim# Network tools Such as ifconfigyum install net-tools shuts down SELinux

Check to see if SELinux is enabled:

Getenforce

Turn off SELinux:

Open the SELinux configuration file

Vim / etc/selinux/config

Modify the following, and the configuration file will take effect the next time you restart

SELINUX=disabled

Temporarily shut down SELinux

Setenforce 0 enlarges file handle

Sets the number of files that can be opened simultaneously. If this value is too small, it will affect server performance, such as opening a database connection requires opening a file.

The Centos7 default value is 1024. Tencent Cloud CentOS7 server is set to 100001 by default.

Execution

Ulimit-a

Where open files (- n) 1024 is the maximum value of the file handle.

Execution

Vi / etc/security/limits.conf

Modify

*-nofile 100001

Or

@ users soft nofile 100001@users hard nofile 100002@root soft nofile 100001@root hard nofile 100002

Restart the system after modification to see if the modification takes effect.

Reduce the waiting time for the startup interface

When CentOS7 starts, a selection interface appears. The first option is normal startup, and the second option is safe mode startup. The default wait time is 5 seconds. It's a waste of time. It can be changed to 1 second.

Vi / boot/grub2/grub.cfg

Change 5 to 1

If [x$feature_timeout_style = xy]; then set timeout_style=menu # change 5 to 1 set timeout=5# Fallback normal timeout code in case the timeout_style feature is# unavailable.else # here change 5 to 1 set timeout=5fi update system

Update the system to the latest version.

Yum update install VMware Tools

Now click Virtual Machine on the virtual machine menu-reinstall VMware Tools and set up the shared directory.

Mkdir / mnt/cdrommount-t iso9660 / dev/cdrom / mnt/cdromcd / mnt/cdromtar-zxvf VMwareTools-*.tar.gz-C / tmpcd / tmp/vmware-tools-distribumount / mnt/cdromrm-rf / mnt/cdromyum update kernelyum install perl gcc kernel-devel./vmware-install.pl

Press enter by default all the time. You can enter the shared directory when you are finished.

Cd / mnt/hgfs/ switching terminal

Ctrl + Alt + F1 to Ctrl + Alt + F6 can switch different terminals.

Restart and shutdown

Restart: shutdwon-r now or reboot

Shutdown: shutdwon-h now or halt
