so you see server2 says the latest version is 1.8.* server 1 says 1.9.* is

they differ in base, epel, extras mirrors,

how can i load the same version on server2 ?

Answer 1

The different servers are using different CentOS mirrors, one of which may not (yet) be completely in sync with upstream.

Your yum repository configuration by default uses the mirrorlist=http://mirrorlist.centos.org/... directive, which non-deterministically determines a good mirror. Another server can and will often use an alternate mirror.

You can point both to the same mirror by using the baseurl= directive in your yum repository instead of using mirrorlist.

Answer 2

The packages you try to update seems to be different as per the output.. web2 shows mod-pagespeed-beta where as web shows mod-pagespeed-stable. Make sure you are updating the correct package. Instead you can try "yum update mod-pagespeed-stable".
