I installed syslog-ng on an offline CentOS 6.x machine by first downloading all required rpms using this command: 

yumdownloader --resolve syslog-ng

There were two files needed, that did not download and I downloaded them separately using:

yumdownloader eventlog-0.2.13-1.el6.x86_64.rpm

and:

yumdownloader libnet-1.1.6-7.el6.x86_64.rpm

These are the files I moved to the offline server:

17,684 eventlog-0.2.13-1.el6.i686.rpm

17,804 eventlog-0.2.13-1.el6.x86_64.rpm

122,940 gamin-0.1.10-9.el6.i686.rpm

1,738,964 glib2-2.28.8-9.el6.i686.rpm

4,570,040 glibc-2.12-1.209.el6_9.2.i686.rpm

117,400 libgcc-4.4.7-18.el6.i686.rpm

60,464 libnet-1.1.6-7.el6.i686.rpm

59,196 libnet-1.1.6-7.el6.x86_64.rpm

111,688 libselinux-2.0.94-7.el6.i686.rpm

309,920 libstdc++-4.4.7-18.el6.i686.rpm

161,168 nss-softokn-freebl-3.14.3-23.3.el6_8.i686.rpm

201,096 pcre-7.8-7.el6.i686.rpm

452,548 syslog-ng-3.2.5-4.el6.i686.rpm

451,092 syslog-ng-3.2.5-4.el6.x86_64.rpm

63,536 tcp_wrappers-libs-7.6-58.el6.i686.rpm

74,284 zlib-1.2.3-29.el6.i686.rpm

Once I moved all these files to the offline server into their own folder, I ran: 

rpm –ivh *.rpm

to install.

I then checked the config file, made a couple of tweaks, then started syslog-ng using:

service syslog-ng start

I got the following errors:

Plugin module not found in 'module-path'; module-path='/lib64/syslog-ng', module='afsql'

Plugin module not found in 'module-path'; module-path='/lib64/syslog-ng', module='afsql'

[ OK ]

Syslog-ng was now running, just with these two errors.

A quick google pointed to the problem, syslog-ng is looking for the sql plugin and the solution:

yum install syslog-ng-libdbi

But when I tried to run

yumdownloader syslog-ng-libdbi

I got

"Nothing to download"

And when I tried

yum install --downloadonly syslog-ng-libdbi

I got

"Nothing to do"

So here are my questions:

1.       Will syslog-ng run just fine receiving udp and sending udp with those errors and without that module?  If, so, I don’t care if I don’t get that module.

2.       Is it possible to run syslog-ng and disable that module in the run command?

3.       Can I remove syslog-ng and re-install disable that module on install?

4.       I’d rather not recompile if I don’t have to, but I found instructions for how to do that.  Any tips would be appreciated.

Thanks.
