mrtg安装过程中遇到问题的整理

1.cfgmaker时候，出现--snpo: Skipping ifName scanning because public@172.16.147.21: does not seem to support it

2./usr/bin/mrtg /data1/apache/htdocs/mrtg/121.122.122.21/mrtg.cfg
 出现如下错误
ERROR: Mrtg will most likely not work properly when the environment
       variable LANG is set to UTF-8. Please run mrtg in an environment
       where this is not the case. Try the following command to start:
 
       env LANG=C /usr/bin/mrtg /data1/apache/htdocs/mrtg/121.122.122.21/mrtg.cfg

3.snmpd进程消失，查看日志
/var/log/snmpd.log看到
cat snmpd.log
netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()

解决办法
1，2实际都是客户端snmpd的配置snmpd.conf出问题导致，目前是这样解决，snmpd.conf改为只写一句rocommunity public

3.按网上说法改装5.4.2就不会有问题，实际上现在时改装5.1.4，同样正常了。
