nano /opt/syslog-ng/etc/syslog-ng.conf

Syslog-ng receives log messages from a source. To define a source you should follow the following syntax:

source <identifier> { source-driver(params); source-driver(params); … };

For example you have to define the following source:

source my_source{ tcp ( port ( 614 ) ); };

In syslog-ng log messages are sent to files. The destination syntax is very similar to sources:

destination <identifier> {destination-driver(params); destination-driver(params); … };

You will be normally logging to a file, but you could log to a different destination-driver: pipe, unix socket, TCP-UDP ports, terminals or to specific programs.

destination my_dest{ file(“/var/log/mylog.txt”); };

GRANT SELECT , INSERT , UPDATE , DELETE , CREATE , DROP , INDEX , ALTER ON `syslog` . * TO ‘syslog’@'localhost’;

SET PASSWORD FOR ‘syslog’@'localhost’ = PASSWORD( ‘syslog’ )

Edit syslog-ng config appropriately; add these rows in the destination section (if you want to use Postgres you have to change mysql to pgsql):

sql(type(mysql)
host(“localhost”)
username(“syslog”)
password(“syslog”)
database(“syslog”)
table(“logs”)
columns(“host”, “facility”, “priority”, “level”, “tag”, “datetime”, “program”, “msg”, “seq”)
values(“$HOST_FROM”, “$FACILITY”, “$PRIORITY”, “$LEVEL”, “$TAG”, “$YEAR-$MONTH-$DAY $HOUR:$MIN:$SEC”, “$PROGRAM”, “$MSG”, “$SEQNUM”)
indexes(“host”, “facility”, “priority”, “datetime”, “program”, “seq”));

Syslog-ng connects sources, filters and destinations with log statements. The syntax is:

log { source(src); filter(f_mail); filter(f_info); destination(mailinfo); };

So you have to connect my_source with my_dest:

log { source( my_source ); destination( my_dest ); };
