我正在尝试设置我的ec2实例(运行amazon
linux,据我所知是建立在RHEL 5上)来将日志消息转发到loggentries.com,但没有任何东西被转发.作为一个完整性检查,我按照指令
in this article设置另一个ec2实例作为中央服务器,发现没有收到消息.所以我尝试在客户机上执行logger -p cron.info TEST,发现没有添加到/ var / log / cron中！有些东西显然不起作用！但是rsyslogd正在运行：
ps aux | grep rsys
root 25362 0.0 0.0 183768 1328 ? Sl 14:27 0:00 /sbin/rsyslogd -i /var/run/syslogd.pid -c 5
供参考,这里是rsyslog.conf(暂时删除了转发内容,直到我在本地工作)
#### MODULES #### $ModLoad imuxsock.so # provides support for local system logging (e.g. via logger command) $ModLoad imklog.so # provides kernel logging support (prevIoUsly done by rklogd) #$ModLoad immark.so # provides --MARK-- message capability # Provides UDP syslog reception #$ModLoad imudp.so #$UDPServerRun 514 # Provides TCP syslog reception #$ModLoad imtcp.so #$InputTcpserverRun 514 #### GLOBAL DIRECTIVES #### # Use default timestamp format $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat # File syncing capability is disabled by default.

解决方法
您在rsyslog.conf中转发到远程IP地址唯一需要的是
*.* @@192.0.2.25:514;
关于你的其他问题……
I tried executing logger -p cron.info TEST on the client machine and found nothing is added to /var/log/cron!
确保在更改配置后重新启动rsyslogd;你还需要确保/ var / log / cron存在.
编辑
为了演示成功的日志条目是什么样的,我用rsyslogd -c4 -d开始了rsyslogd;这会将所有调试发送到我的ssh会话.我正在将cron.info记录到/ var / log / syslog.在一个不同的ssh会话中,我运行了logger -p cron.info“我的测试再次”…这是我在成功登录到/ var / log / syslog之前看到的…
