Dear John,
I used syslog-ng_1.6.x , there has a startup script (maybe init.d.RedHat-7.3 ) in install directory . So I can start or stop it very easy . But in syslog-ng_1.9.5 , I haven't found the startup script , there is not convenience. I used logrotate.d separate log files . when the logrotate.d finished , it will restart the syslog-ng service . if there haven't startup script , I must added a script in logrotate.conf :
Why not use the syslog-ng-1.6.x startup script?
postrotate /usr/bin/killall -HUP /usr/local/syslog-ng/sbin/syslog-ng 2> /dev/null || true endscript
above script always killed the syslog-ng process and not startup syslog-ng process .I don't know the reason.
This indeed is a bit strange as -HUP should not kill the process per se with regard to syslog-ng. I've just tested this and and if I do it by hand the syslog-ng process is indeed killed by this, although not all the time. Some short time digging reveiled following:
webphish:~ # ulimit -c unlimited webphish:~ # /sbin/syslog-ng-1.9.5 -v -d -d -F
[in another terminal send a /usr/bin/killall -HUP /sbin/syslog-ng-1.9.5]

No time to further dig into this yet.
when i used syslog-ng_1.6.x , I can use a easy script instead of above script :
postrotate service syslog-ng restart endscript
Check out the contrib directory of the syslog-ng-1.6.x source tree and there you'll find all the startup scripts needed. They should also work for the 1.9.x drop of syslog-ng.
Bazsi, do you think that copying the contrib directory from 1.6.x to 1.9.x would make sense?
Could you give me a suggestion ! thanks .
