A lot of clients prefer centos 7 and centos 8. you should try to upgrade to that.
Try to update is first clean all, second update glibc, yum, rpm and python packages and then update other packages like following:
yum clean all
yum update glibc* yum* rpm* python*
yum update
You can try this: CentOS 6.6 is old and the normal update will go to the latest 6.x version. To get exactly 6.6, you need to use a specific repository or ISO for 6.6.
Steps:
Backup your data.
Change your repo files to point to CentOS 6.6 vault repo. Example: http://vault.centos.org/6.6/os/x86_64/.
Run yum clean all.
Run yum update again.
This should update your system to 6.6 only.
Be aware that CentOS 6 is end of life and not supported anymore.
If you want, I can write exact repo file content for 6.6. Do you want me to do that?
