linux远程日志rsyslog服务端和客户端安装

用rsyslog的缘由：

#指定安装目录  
./configure --prefix=/Application/rsyslog  
 
#编译  
make  
 
#安装  
make install  
#添加lib  
echo "/Application/rsyslog/lib/rsyslog" >> /etc/ld.so.conf  
#更新lib  
ldconfig  
 
#产生配置文件  
cp /etc/syslog.conf /etc/rsyslog.conf 

#!/bin/bash  
#  
# rsyslog Starts rsyslogd/rklogd.
