This article introduces the relevant knowledge of "Linux red hat server building method". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

This article provides solutions to three problems built by Linux servers.

1. How to use yum to install common software when the server is not connected to the Internet

First mount the Linux system installation disk and put the CD into the server external optical drive. Create a new mount directory

# mkdir / cdrom

# ls-l / dev/sr* confirm the name of the file mounted on the CD, assuming / dev/sr0#

# mount / dev/sr0 / cdrom/ CD-ROM files are mounted to / cdrom

# mkdir / iso create a copy file directory

# cp / cdrom/* / iso copy all the CD files into the iso directory

# cd / etc/yum.repos.d enter the yum configuration file directory

# vi dvd.repo New CD as the yum configuration file from which the software is downloaded

The dvd.repo content is as follows

# yum clean all clears yum cache

Now you can use the yum command to install common software when you are not connected to the Internet, because there will be rpm packages of commonly used software on the Linux installation disk.

Configure the domain name resolution server

Vi / etc/resolv.conf

Nameserver 114.114.114.114

Nameserver 8.8.8.8

Restart the network service to take effect

3. The ftp tool cannot connect to the system

The server that has just configured the network uses the ftp tool to log in, and there is a 500 error message.

Reason: redhat is aimed at enterprises. For the sake of security, a selinux service has been added, which restricts the login of root users to the ftp service.

Solution:

(1) Open / etc/selinux/config with vi editor

(2) change enforcing to disabled save and exit

(3) run the setenforce 0 command to take effect immediately.

If the connection is still unsuccessful

(1) check whether the vsftpd service is enabled

(2) turn off the firewall

(3) whether the user name or password is entered incorrectly
