I thank you for your help.

yum clean && yum check-update

[esbbbr]

Thank you.
I tested this method , Not working
my idea : download all package from repo and create local repo and instal zabbix from local repo

[Firm]

You don't need to create repo. Just download rpms and install them with rpm -i <rpm> [<rpm>]

[varnav]

yum clean all

not

yum clean

As described here:

https://www.zabbix.com/documentation/3.0/manual/installation/install_from_packages#red_hat_enterprise_linuxcentos

# rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
# yum install zabbix-agent

and similar issue:

 One of the configured repositories failed (Zabbix Official Repository - x86_64),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable zabbix

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=zabbix.skip_if_unavailable=true

failure: repodata/primary.xml.gz from zabbix: [Errno 256] No more mirrors to try.

Few days ago i have managed to install successfully few agents. It seems like repo misconfiguration on server site.

Thank you for your help.
