Build a network source in CentOS 6.4

When your Linux system can connect to the network, I think you will not need to install local and rpm software. The network source is to install the software you want through the resources on the network, in this way, the system can be updated and maintained in a timely manner.

1. Ensure that your server can connect to the Internet
[Root @ CentOS ~] # Ifconfig eth0
Eth0 Link encap: Ethernet HWaddr 08: 00: 27: 56: AA
Inet addr: 2.2.2.145 Bcast: 2.20.255.255 Mask: 255.0.0.0
Inet6 addr: fe80: a00: 27ff: fe56: aaaa/64 Scope: Link
Up broadcast running multicast mtu: 1500 Metric: 1
RX packets: 424 errors: 0 dropped: 0 overruns: 0 frame: 0
TX packets: 95 errors: 0 dropped: 0 overruns: 0 carrier: 0
Collisions: 0 FIG: 1000
RX bytes: 36395 (35.5 KiB) TX bytes: 12020 (11.7 KiB)
[Root @ centos ~] # Ping www.baidu.com
PING www.a.shifen.com (115.239.210.27) 56 (84) bytes of data.
64 bytes from 115.239.210.27: icmp_seq = 1 ttl = 54 time = 18.1 MS
64 bytes from 115.239.210.27: icmp_seq = 1 ttl = 54 time = 17.9 MS

2. Edit the yum library file (using the official source)

[Root @ RedHat1 ~] # Cd/etc/yum. repos. d/
[Root @ redhat1 ~] # Vim CentOS-Base.repo-with the official source (remove all baseurl before)
[Base]
Name = CentOS-$ releasever-Base
Using list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = OS
Baseurl = http://developer.centos.org/centos/?releasever/ OS /?basearch/
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
# Released updates
[Updates]
Name = CentOS-$ releasever-Updates
Using list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = updates
Baseurl = http://developer.centos.org/centos/?releasever/updates/?basearch/
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
# Additional packages that may be useful
[Extras]
Name = CentOS-$ releasever-Extras
Using list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = extras
Baseurl = http://developer.centos.org/centos/?releasever/extras/?basearch/
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
# Additional packages that extend functionality of existing packages
[Centosplus]
Name = CentOS-$ releasever-Plus
Using list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = centosplus
Baseurl = http://developer.centos.org/centos/?releasever/centosplus/?basearch/
Gpgcheck = 1
Enabled = 1 -- enable Repository
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
# Contrib-packages by Centos Users
[Contrib]
Name = CentOS-$ releasever-Contrib
Using list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = contrib
Baseurl = http://developer.centos.org/centos/?releasever/contrib/?basearch/
Gpgcheck = 1
Enabled = 1 -- enable Repository
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

3. Use Netease's network source (the same is true for other open-source image sites)
[Root @ centos1 ~] # Cd/etc/yum. repos. d/-- enter the root directory of the repository.
[Root @ centos1 yum. repos. d] # ll
