# Don't log private authentication messages!

$InputFileName         /var/log/webfront/webfront.log      #要监控的日志文件路径
$InputFileTag          webfront-info:                      # 定义文件标签 ，注意最后是冒号：
$InputFileStateFile    state-webfront-info                 #定义状态文件
$InputRunFileMonitor                                       #激活读取，可以设置多组日志读取，每组结束时设置本参数

# ### 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

# ### end of the forwarding rule ###

一般默认配置即为发送系统日志，可以不做修改，注意最后
. @@remote-host:514 修改为目标日志服务器ip

2. 重启rsyslog

方法1：

/etc/init.d/rsyslog restart #修改配置文件后一定要重启rsyslog服务

/etc/init.d/rsyslog status  #可查看服务状态

方法2：

service rsyslog restart #修改配置文件后一定要重启rsyslog服务

service rsyslog status  #查看服务状态

3. 在10.44.85.15上修改/etc/rsyslog.conf

5. 检验日志收集

在日志服务器10.44.85.15上查看通过rsyslog收集的10.44.85.16的日志

日志路径：

cd /var/log/10.44.85.16/
