Build your own yum warehouse, add your own rpm package to your yum source. The server configuration of yum warehouse is as follows:

1. Create a yum warehouse directory

Mkdir-p / data/yum_data/

Cd / data/yum_data/

# you can upload rpm packages to this directory, and folders can also be included under this directory

two。 Install createrepo softwar

[root@yum yum_data] # yum-y install createrepo 3. Initialize the repodata index file

Createrepo-pdo / data/yum_data/ / data/yum_data/

4. Provide yum services

# you can use Apache or nginx to provide web service, which is suitable for private network environment

Yum Source configuration based on HTTP

Install apache softwar

[root@yum yum_data] # yum install-y httpd

[root@yum yum_data] # / etc/init.d/httpd start

Starting httpd: [OK]

[root@yum yum_data] # netstat-lntup | grep httpd

Tcp 0 0: 80: * LISTEN 6403/httpd

# configure according to your server ip address

[root@yum yum_data] # echo "192.168.30.130 yum.nulige.com" > > / etc/hosts

[root@yum yum_data] # tail-1 / etc/hosts

192.168.30.130 yum.nulige.com

# add hosts parsing to window system

192.168.30.130 yum.nulige.com

# visit the website

Enter: yum.nulige.com in the browser

# modify configuration file / etc/httpd/conf/httpd.conf

Point the default www directory to the locally created yum repository directory

[root@YUM] # yum-- enablerepo=localyum-- disablerepo=base,extras,updates,epel list

# permanent use requires modifying the configuration file to close the default repo file

Cd / etc/yum.repos.d/

Vi CentOS-Base.repo# is enabled at each startup source with the addition of # enabled=0 # to 1, and is enabled without this parameter. [base]. Enabled=0 [updates]. Enabled=0 [extras]. Enabled=0

Note: there are other open warehouses that use this method to close.

Or

Use the following method to move all the repo ending files under / etc/yum.repos.d/ to other directories.

1 mkdir-p / home/nulige/yum_backup 2 3 cd / etc/yum.repos.d 4 5 mv * / home/nulige/yum_backup synchronous Mirror Public Network Image YumSource configuration method

But there is also a kind of enterprise demand, to be more specific, usually everyone downloads yum installation software from the public network and takes up bandwidth, so set up an intranet yum server in the company, but also take into account that if the database file repodata of yum software is different, there will be a problem. So the solution I can think of is to directly use the repodata of the public network yum source. Mirror synchronization public network yum source

The upstream yum source must support the rsync protocol, otherwise rsync cannot be used for synchronization.

Http://mirrors.ustc.edu.cn/status/

Official standard source of CentOS: rsync://mirrors.ustc.edu.cn/centos/

Epel source: rsync://mirrors.ustc.edu.cn/epel/

Synchronization command:

# use rsync to synchronize yum sources. In order to save bandwidth, disk and download time, I only synchronized CentOS6 rpm packages, so that all rpm packages take up only 21G, and all synchronization takes about 300G.

# synchronize base feeds, tips. The CD image of our installation system contains some rpm packages, about 3G, so you don't have to download them again.

# create four directories to synchronize public network yum sources

Mkdir-p / data/yum_data/centos/6/os/x86_64/

Mkdir-p / data/yum_data/centos/6/extras/x86_64/

Mkdir-p / data/yum_data/centos/6/updates/x86_64/

Mkdir-p / data/yum_data/epel/6/x86_64/

# if the following four commands are copied and executed at the same time, you will start to synchronize the yum source to the local official website.

/ usr/bin/rsync-av rsync://mirrors.ustc.edu.cn/centos/6/os/x86_64/ / data/yum_data/centos/6/os/x86_64/ / usr/bin/rsync-av rsync://mirrors.ustc.edu.cn/centos/6/extras/x86_64/ / data/yum_data/centos/6/extras/x86_64/ / usr/bin/rsync-av rsync://mirrors.ustc.edu.cn/centos/ 6/updates/x86_64/ / data/yum_data/centos/6/updates/x86_64/ / usr/bin/rsync-av-- exclude=debug rsync://mirrors.ustc.edu.cn/epel/6/x86_64/ / data/yum_data/epel/6/x86_64/

Fault handling:

Error:

ERROR: max connections (20) reached-- try again later

Rsync error: error starting client-server protocol (code 5) at main.c (1503) [receiver=3.0.6]

Solution:

The yum source server exceeds the maximum number of connections. Please try again later. (try a few more times and you will succeed.)

Error:

# rsync: getaddrinfo: mirrors.ustc.edu.cn 873: Name or service not known

Solution:

DNS cannot be parsed, add mobile DNS
