Use rsync to synchronize the Internet centos Yum source as the local Yum source server

Use rsync to synchronize the Internet centos Yum source as the local Yum source server

1. Install httpd, rsync, and vsftpd.

Yum-y install httpd rsync vsftpd

Mkdir/var/www/html/centos

# Because vsftpd does not support changing directories through soft connections, the following operations are the same

Mount -- bind/var/www/html/centos/var/FTP/pub

Chkconfig httpd on

Chkconfig vsftpd on

Service httpd start

Service vsftpd start

2. The Rsync synchronization script is as follows:

#! /Bin/bash

# Base Value

# Source to be synchronized

Yum_site = "rsync: // mirrors.kernel.org/centos /"

# Local storage directory

Local_path = "/u01/mirrors/centos /"

# For the version to be synchronized, I only need a total of around GB for versions 5, 6, and 7. After removing ISO, there will be fewer

Local_ver = "5 5*6 6*7 7 *"

# Bandwidth limit during Synchronization

Bw_limit = 512

# Recording the script process number

Lock_file = "/var/log/yum_server.pid"

# If Rsync is empty by default.

# Fill in the complete path directly with the rsync tool installed by yourself

Rsync_path = ""

 

# Check update Yum server PID

My_pid =$ $

If [-F $ lock_file]; then

Get_pid = '/bin/CAT $ lock_file'

Get_system_pid = '/bin/PS-Ef | grep-V grep | grep $ get_pid | WC-l'

If [$ get_system_pid-EQ 0]; then

Echo $ my_pid> $ lock_file

Else

Echo "have update Yum server now! "

Exit 1

Fi

Else

Echo $ my_pid> $ lock_file

Fi

 

# Check rsync Tool

If [-Z $ rsync_path]; then

Rsync_path = '/usr/bin/whereis rsync | awk ''' {print $2 }''

If [-Z $ rsync_path]; then

Echo 'not find rsync tool .'

Echo 'use COMM: Yum install-y rsync'

Fi

Fi

 

# Sync Yum Source

For ver in $ local_ver;

Do

# Check whether there are local directory

If [! -D "$ local_path $ Ver"]; then

Echo "create dir $ local_path $ Ver"

'/Bin/mkdir-p $ local_path $ ver'

Fi

# Sync Yum Source

Echo "Start sync $ local_path $ Ver"

$ Rsync_path-avrth -- delete -- bwlimit = $ bw_limit -- exclude "ISOs" $ yum_site $ ver $ local_path

Done

 

# Clean lock file

'/Bin/Rm-RF $ lock_file'

 

Echo 'sync end .'

Exit 1

3. Schedule Tasks

Update every morning

23 59 ***/root/yumrsync

4. Client Configuration

Edit/etc/yum. Repos. d/CentOS-Base.repo

Find/etc/yum. Repos. d/-type F-name "*. Repo"-exec CP {}{}. Bak \;

Find/etc/yum. Repos. d/-name "*. Repo" | xargs sed-I's/# baseurl = http: \ // developer.centos.org/baseurl#http:#/#/192.168.0.100/g'

Run the preceding command to modify the settings. The result is as follows:

# Base
