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：

[root@192_168_103_42 yum.repos.d]# 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

[root@192_168_103_42 rpm-gpg]# 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

  [root@192_168_103_42 rpm-gpg]# rpm -e gpg-pubkey-d88e42b4-52371eca
error: "gpg-pubkey-d88e42b4-52371eca" specifies multiple packages
[root@192_168_103_42 rpm-gpg]# rpm -e --allmatches gpg-pubkey-d88e42b4-52371eca
