rsyslog 不记录消息

  • 772

我正在尝试设置我的 ec2 实例（运行 amazon linux，据我所知，它是建立在 RHEL 5 上的）将日志消息转发到 loggentries.com，但没有任何内容被转发。作为健全性检查，我按照本文中的说明将另一个 EC2 实例设置为中央服务器，发现没有收到消息。所以我尝试logger -p cron.info TEST在客户端机器上执行，发现/var/log/cron 中没有添加任何内容！显然有些东西不起作用！但是 rsyslogd 正在运行：

ps 辅助 | grep rsys

产出

根 25362 0.0 0.0 183768 1328 ？Sl 14:27 0:00 /sbin/rsyslogd -i /var/run/syslogd.pid -c 5

作为参考，这里是 rsyslog.conf（暂时删除了转发内容，直到我让它在本地工作）

#### 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. This feature is usually not required, 
# not useful and an extreme performance hit
#$ActionFileEnableSync on

    您唯一需要rsyslog.conf转发到远程 IP 地址的是

    *.* @@192.0.2.25:514;

    关于你的另一个问题...

    我尝试在客户端计算机上执行 logger -p cron.info TEST，但发现/var/log/cron 中没有添加任何内容！

    确保在更改配置后重新启动 rsyslogd；您还需要确保它/var/log/cron存在。

    编辑

    为了演示成功的日志条目是什么样的，我rsyslogd从rsyslogd -c4 -d; 这会将所有调试发送到我的 ssh 会话。我登录cron.info到/var/log/syslog. 在另一个 ssh 会话中，我运行了logger -p cron.info "my test again"……这是我在成功登录之前看到的/var/log/syslog……
