我有一个 java 程序，我想在 fedora 机器上登录 /var/log/messages 文件。我正在使用 log4j SyslogAppender，但它不起作用。

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

在 /etc/sysconfig/rsyslog 中有

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。我也尝试过使用默认的 USER 工具，尽管logger -p LOCAL1.infocmd 正在工作并将日志附加到 app.log，但它不起作用。需要帮忙。

我在 log4j 端看不到任何问题，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

这表明它不能-r与. 而不是尝试在此处设置远程访问，您应该编辑并添加（或取消注释）-m 0-c 4/etc/rsyslogd.conf

看看这是否可以帮助您，因为它对我来说运行良好！问候阿南德·巴特

这里的问题是

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

应该

SYSLOGD_OPTIONS="-r -m 0"

这些选项不能一起使用
