I'm attempting to install Nagios plugins on a Zimbra 8.0.2 server running CentOS 6.4, but have run into the following error when I run yum install nagios-plugins-all

Error: Package: nagios-plugins-mysql-1.4.15-2.el5.x86_64 (epel)
           Requires: libmysqlclient.so.15()(64bit)
Error: Package: nagios-plugins-pgsql-1.4.15-2.el5.x86_64 (epel)
           Requires: libpq.so.4()(64bit)
Error: Package: nagios-plugins-mysql-1.4.15-2.el5.x86_64 (epel)
           Requires: libmysqlclient.so.15(libmysqlclient_15)(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

How can I install these libraries (libmysqlclient.so.15 & libpq.so.4)?

Will installing these libraries possibly break Zimbra?

  • These should already be available in the base repositories. What changes have been made to them on this server? Jun 29, 2013 at 1:33
  • None that I'm aware of. I installed Zimbra 8.0.2 on a fresh CentOS 6.3 install (which has been updated to 6.4 now). And also installed nrpe. I've also installed the EPEL repo. Jun 29, 2013 at 1:39

Looks like I had to remove some cached packages:

Resolved this by running:

yum clean all


yum clean metadata

the latest version of nagios-plugins (1.4.16-5.el6.x86_64.rpm) was then available via the epel repo when running yum install nagios-plugins-all

  • nice, this answer fixed the same issue in centos 7
