rsyslog

1   自定义一个rsyslog服务配置项

[root@localhost rsyslog.d]# pwd
/etc/rsyslog.d
[root@localhost rsyslog.d]# cat jkktest.conf 
if ($programname == 'jkktest')
then -/var/log/jkktest.log

使用 logger -it jkktest   "loginfo"  就能向 jkktest 的日志/var/log/jkktest.log 中写入日志信息了

[root@localhost rsyslog.d]# logger -it jkktest  "123456789"
[root@localhost rsyslog.d]# cat /var/log/jkktest.log 
Nov 28 22:24:58 localhost jkktest[10617]: 123456789

丰富相关配置项，例如日志转储等

[root@localhost log]# cat /etc/logrotate.d/jkktest 
/var/log/jkktest.log
{
    missingok
    size 1k
    rotate 5
    postrotate
    service rsyslog restart
    endscript
}
