*WARNING: windows admin trying to drive linux!*

hey all,
Can someone give me a hand sorting this problem i've got with installing rsyslog, please? I've got a CentOS 4.2 box I've installed running Apache & MySQL at the moment with the aim of creating a centralised logging server for our windows environment...... but i'm having issues installing rsyslog.
so far i've followed the step by step guide and it all goes fine up untill "make" then it all goes slightly Pete Tong and I see this:

Code: Select all

make: *** [syslogd] Error 1

any ideas what i've done wrong? i've tried it with both 0 and 1 set in the Makefile as I suspect it's a MySQL problem..... which is something else i'm trying to learn! lol

any help would be appreciated and earn virtual beer tokens

• Custom written rsyslog.conf?
• Maintenance Contract?
• Installation support?

I suspect its a missing MySQL development package. Typically this package is named mysql-dev. Check that you have it.

Then, set the MySQL feature in makefile to 1. Run "make clean" and then make. If there is an error, please post the output of these two make runs.

thanks for the speedy answer, Rainer!

I've had a look through and the MySQL development package was partly installed. I'm going to remove and reinstall it afresh and see what that does.

I'll post again once i've got a result lol

Right, I'm back again! I've managed to reinstall the mysql bits and pieces and have learnt a lot in just doing that lol

anyway, i now get:

Code: Select all

[root@box1 linux]# nano Makefile
[root@box1 linux]# make
cc -s -lpthread -o syslogd syslogd.o pidfile.o template.o outchannel.o stringbuf.o srUtils.o parse.o -lmysqlclient -L/usr/local/lib/mysql
[root@box1 linux]# make install
install ../rfc3195d.8 /usr/share/man/man8/rfc3195d.8
install ../rsyslogd.8 /usr/share/man/man8/rsyslogd.8
install ../rsyslog.conf.5 /usr/share/man/man5/rsyslog.conf.5
install -b -s syslogd /usr/sbin/rsyslogd
[root@box1 linux]#


which i think is good so i'm onto the next step in the world domination via centralised logging plan
