Dependencies

Required

• Glib2
• Eventlog
• Pkg-config

Optional

• TCP Wrappers
• libdbi (Required for SQL Support)
• libnet (Required for Spoof Source)

Non-Multilib

Compile the package:

./configure --prefix=/usr --sysconfdir=/etc/syslog-ng \
    --localstatedir=/var/lib/syslog-ng \
    --enable-ipv6 --enable-tcp-wrapper &&
make

Install the package

make install

Multilib

This package does not provide any libraries so only one installation is needed.

32Bit

Compile the package:

CC="gcc ${BUILD32}" PKG_CONFIG_PATH="${PKG_CONFIG_PATH32}" \
./configure --prefix=/usr --sysconfdir=/etc/syslog-ng \
    --localstatedir=/var/lib/syslog-ng \
    --enable-ipv6 --enable-tcp-wrapper &&
make

Install the package

make install

N32

Compile the package:

CC="gcc ${BUILDN32}" PKG_CONFIG_PATH="${PKG_CONFIG_PATHN32}" \
./configure --prefix=/usr --sysconfdir=/etc/syslog-ng \
    --localstatedir=/var/lib/syslog-ng \
    --enable-ipv6 --enable-tcp-wrapper &&
make

Install the package

make install

64Bit

Compile the package:

CC="gcc ${BUILD64}" PKG_CONFIG_PATH="${PKG_CONFIG_PATH64}" \
./configure --prefix=/usr --sysconfdir=/etc/syslog-ng \
    --localstatedir=/var/lib/syslog-ng \
    --enable-ipv6 --enable-tcp-wrapper &&
make

Install the package

make install

Confuration

Bootscript

Uninstall Sysklogd with the following commands:

rm -v /usr/sbin/{k,sys}logd &&
rm -v /usr/share/man/man5/syslog.conf.5
rm -v /usr/share/man/man8/{sysklogd.8,syslogd.8,klogd.8} &&
rm -v /etc/syslog.conf &&
rm -v /etc/rc.d/*/*sysklogd

Install the init script.

cat > /etc/rc.d/init.d/syslog-ng << "EOF"
#!/bin/sh
# Begin $rc_base/init.d/syslog-ng - Syslog-ng loader 

source /etc/sysconfig/rc
source $rc_functions

case "$1" in
	start)
		echo "Starting System Log..."
	        loadproc /usr/sbin/syslog-ng -f /etc/syslog-ng/syslog-ng.conf
		;;
	stop)
		echo "Stopping System Log..."
		killproc /usr/sbin/syslog-ng
		;;

	restart)
		$0 stop
		sleep 1
		$0 start
		;;

	status)
		statusproc /usr/sbin/syslog-ng
		;;

	*)
		echo "Usage: $0 {start|stop|restart|status}"
		exit 1
		;;
esac

# End $rc_base/init.d/syslog-ng
EOF

Then

for link in /etc/rc.d/rc{{0,1,6}.d/K80,{2,3,4,5}.d/S10}syslog-ng; do
  ln -sfv ../init.d/syslog-ng $link; done

syslog-ng.conf

The following is an example configuration that will work in most situations:

mkdir -pv /etc/syslog-ng &&
cat > /etc/syslog-ng/syslog-ng.conf << "EOF"
# Begin /etc/syslog-ng/syslog-ng.conf

    use_dns (no);
    use_fqdn (no);
    create_dirs (no);
    keep_hostname (yes);
    stats(43200);
    };
