Question

我有一个java程序，我想在fedora机器上登录/ var / log / messages文件。我在log4j SyslogAppender中使用但是它无效。

我的log4j属性文件包含

# Set root category priority to INFO and its only appender to CONSOLE.
log4j.rootCategory=INFO, CONSOLE, SYSLOG
#log4j.rootCategory=INFO, CONSOLE, LOGFILE

# Set the enterprise logger priority to DEBUG
log4j.logger.com.locaid=INFO, CONSOLE, LOGFILE, SYSLOG

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=/home/dev/app.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=[%d{dd/MM/y HH:mm:ss}][%t][%1p] %c - %m%n

log4j.appender.SYSLOG=org.apache.log4j.net.SyslogAppender
log4j.appender.SYSLOG.syslogHost=localhost
log4j.appender.SYSLOG.layout=org.apache.log4j.PatternLayout
log4j.appender.SYSLOG.layout.conversionPattern=%d{ISO8601} %-5p [%t] %c{2} %x - %m%n
log4j.appender.SYSLOG.Facility=LOCAL1
log4j.appender.SYSLOG.Threshold=debug
log4j.appender.SYSLOG.FacilityPrinting=true

在/etc/rsyslog.conf我有

local1.*      /var/log/app.log

/ etc / sysconfig / rsyslog中的

有

SYSLOGD_OPTIONS="-r -m 0 -c 4"

在重新启动rsyslog服务时，会创建app.log文件，但不会附加任何日志。虽然logger -p LOCAL1.info cmd正在运行并将日志附加到app.log，但我还尝试使用默认的USER工具。需要帮助。

Answer 1

我在log4j端看不到任何错误，但我的/etc/default/rsyslog（在Ubuntu上）说

# Options for rsyslogd
# -m 0 disables 'MARK' messages (deprecated, only used in compat mode < 3)
# -r enables logging from remote machines (deprecated, only used in compat mode < 3)
# -x disables DNS lookups on messages received with -r
# -c compatibility mode
# See rsyslogd(8) for more details

表明-r和-m 0无法与-c 4结合使用。您应该编辑/etc/rsyslogd.conf并添加（或取消注释）

，而不是尝试在此处设置远程访问权限

$ModLoad imudp
$UDPServerRun 514

看看这是否可以帮助你，因为它运行正常！问候阿南德巴特

Answer 3

这里的问题是

SYSLOGD_OPTIONS="-r -m 0 -c 4"

应该是

SYSLOGD_OPTIONS="-r -m 0"

这些选项无法一起使用

SyslogAppender无法正常工作
