rsyslog不會發送任何信息

Question

今天是個好日子！

我正在嘗試使用rsyslog將日志文件從一個基於Red Hat的服務器發送到另一個Graylog服務器。 所以我不能這樣做，因為rsyslog不發送任何東西。 如果有人幫忙，我真的很感激！

Graylog通過以下方式接收消息：

echo "Hello Graylog, let's be friends." | nc -w 1 -u "my-graylog-ip" 13101

我配置了rsyslog.config：

# rsyslog configuration file

# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html

#### MODULES ####

# The imjournal module bellow is now used as a message source instead of imuxsock.
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imjournal # provides access to the systemd journal
#$ModLoad imklog # reads kernel messages (the same are read from journald)
#$ModLoad immark  # provides --MARK-- message capability

# Provides UDP syslog reception
#$ModLoad imudp
#$UDPServerRun 514

# Provides TCP syslog reception
#$ModLoad imtcp
#$InputTCPServerRun 514


#### GLOBAL DIRECTIVES ####

# Where to place auxiliary files
$WorkDirectory /var/lib/rsyslog

# 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

# Include all config files in /etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf

# Turn off message reception via local log socket;
# local messages are retrieved through imjournal now.
$OmitLocalLogging on

# File to store the position in the journal
$IMJournalStateFile imjournal.state


#### RULES ####

# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.*                                                 /dev/console

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure

# Log all the mail messages in one place.
mail.*                                                  -/var/log/maillog


# Log cron stuff
cron.*                                                  /var/log/cron

# Everybody gets emergency messages
*.emerg                                                 :omusrmsg:*

# Save news errors of level crit and higher in a special file.
uucp,news.crit                                          /var/log/spooler

# Save boot messages also to boot.log
local7.*                                                /var/log/boot.log


# ### begin forwarding rule ###
# The statement between the begin ... end define a SINGLE forwarding
# rule. They belong together, do NOT split them. If you create multiple
# forwarding rules, duplicate the whole block!
# Remote Logging (we use TCP for reliable delivery)
#
# An on-disk queue is created for this action. If the remote host is
# down, messages are spooled to disk and sent when it is up again.
#$ActionQueueFileName fwdRule1 # unique name prefix for spool files
#$ActionQueueMaxDiskSpace 1g   # 1gb space limit (use as much as possible)
#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown
#$ActionQueueType LinkedList   # run asynchronously
#$ActionResumeRetryCount -1    # infinite retries if host is down
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
*.* @http://"my-graylog-ip":13101
# ### end of the forwarding rule ###

然后重新啟動rsyslog

systemctl restart rsyslog

在/etc/rsyslog.d/中找到grid.conf：

# File 1 
$ModLoad imfile 
$InputFileName /home/ucp/current-envelope/log/envelope.log 
$InputFileTag def-grid101-envelope
$InputFileFacility local0
$InputRunFileMonitor
# File 2 
ModLoad imfile 
$InptFileName /home/ucp/current-envelope/log/envelope-err.log 
$InputFileTag def-grid101-envelope
$InputFileFacility local0 
$InputRunFileMonitor
# File 3 
$ModLoad imfile 
$InputFileName /home/ucp/current-envelope/log/performance.log 
$InputFileTag def-grid101-envelope
$InputFileFacility local0 
$InputRunFileMonitor

journalctl -b | grep rsyslog顯示下一條消息：

Mar 23 10:24:01 grid101 kernel: type=1130 audit(1490253841.179:135915): pid=1 uid=0 auid=4294967295 ses=4294967295 msg='unit=rsyslog comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success'

Answer 1

IP:port配置不正確。 對於TCP，必須將其更改為類似的內容：

*.* @@my-graylog-ip:13101

我想知道你的Graylog服務器為什么使用13101 TCP端口。 我猜，它背后是NAT或類似的東西。 我也想知道你為什么要在你的配置中使用http://東西。
