1、使用rpm命令安裝keepalived時，得到error提示如下
[root@localhost ~]# rpm -i keepalived-1.3.5-1.el7.x86_64.rpm
warning: keepalived-1.3.5-1.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
error: Failed dependencies:

libnetsnmpmibs.so.31()(64bit) is needed by keepalived-1.3.5-1.el7.x86_64
2、使用yum安裝net-snamp
[root@localhost ~]# yum install net-snmp
