1. 服务器端：
在 /etc/syslog-ng/syslog-ng.conf中配置：
#
# configuration file for syslog-ng, customized for remote logging
#
options {
use_fqdn(yes);
chain_hostnames(off);
keep_hostname(off);
sync(0);
# The default action of syslog-ng 1.6.0 is to log a STATS line
# to the file every 10 minutes. That's pretty ugly after a while.
# Change it to every 12 hours so you get a nice daily update of
# how many messages syslog-ng missed (0).
stats(43200);
create_dirs(yes);
};

2，重新启动 syslog服务：
rcsyslog restart
3.客户端配置：在配置文件syslog-ng.conf中加入两行：
destination d_udp { udp("服务端IP" port(514)); };
log { source(src); destination(d_udp); };’
重新启动syslog-ng服务
rcsyslog restart
或者：/etc/init.d/syslog-ng restart
