rhel5.4中导入pubkey报错及解决方法
在rhel5系统中导入V4的KEY的时候出现如下错误：
# rpm --import https://packages.elasticsearch.org/GPG-KEY-elasticsearch
error: https://packages.elasticsearch.org/GPG-KEY-elasticsearch: import read failed(-1).
解决方法： wget https://packages.elasticsearch.org/GPG-KEY-elasticsearch
rpm --import GPG-KEY-elasticsearch
yum install logstash -y
报错：
error: rpmts_HdrFromFdno: Header V4 RSA/SHA1 signature: BAD
原因：
v4 signature are used by default in Centos 6, but Centos 5 only supports v3.
查看pubkey情况：
1、rpm -q gpg-pubkey
2、rpm -qi gpg-pubkey-d88e42b4-52371eca
当多次导入重复的pubkey时
# rpm -q gpg-pubkey-d88e42b4-52371eca
gpg-pubkey-d88e42b4-52371eca
gpg-pubkey-d88e42b4-52371eca
可以进行清除，但必须加上--allmatches参数
# rpm -e gpg-pubkey-d88e42b4-52371eca
error: "gpg-pubkey-d88e42b4-52371eca" specifies multiple packages
# rpm -e --allmatches gpg-pubkey-d88e42b4-52371eca
