RedHat CentOS system source

RedHat cannot use the official update source. Therefore, you have to replace the RedHat official source with the CentOS open source. The procedure is as follows:

1. Replace the RedHat yum program:

[Plain] view plaincopy

1. [Root @ leekwen] # cat/etc/issue
2. RedHatEnterpriseLinuxServerrelease5.5 (Tikanga)
3. Kernel \ ronan \ m
5. [Root @ leekwen] # rpm-qa | grepyum
6. [Root @ leekwen] # rpm-eyum-3.2.22-20.el5 -- nodeps
7. [Root @ leekwen] # rpm-eyum-updatesd-0.9-2.el5 -- nodeps
8. [Root @ leekwen] # rpm-eyum-security-1.1.16-13.el5 -- nodeps
9. [Root @ leekwen] # rpm-eyum-metadata-parser-1.1.2-3.el5 -- nodeps
10. [Root @ leekwen] # rpm-eyum-rhn-plugin-0.5.4-13.el5 -- nodeps

2. Download The CentOS yum Program (My 32bit server is here. If the 64-bit server is used, modify the download path on your own ):

1. [Root @ leekwen] # wget-chttp: // logs
2. [Root @ leekwen] # wget-chttp: // logs
3. [Root @ leekwen] # wget-chttp: // logs

3. Install the CentOS yum program:

1. [Root @ leekwen] # rpm-ivhyum-3.2.22-40.el5.centos.noarch.rpmyum-fastestmirror-1.1.16-21.el5.centos.noarch.rpmyum-metadata-parser-1.1.2-4.el5.i386.rpm

4. Modify the yum source of CentOS:
