[Solved] Error in installing RPM package in CentOS – no key

Because this machine is newly installed centos7 , NC – netcat is not installed by default, so an RPM package is downloaded. The installation error is as follows:

[cos@localhost Desktop]$ ls
netcat-0.7.1-1.i386.rpm
[cos@localhost Desktop]$ rpm -ivh netcat-0.7.1-1.i386.rpm 
Warning: netcat-0.7.1-1.i386.rpm: Header V3 DSA/SHA1 Signature, key ID b2d79fc1: NOKEY
Error: Dependency detection failed.
    libc.so.6 required by netcat-0.7.1-1.i386
    libc.so.6(GLIBC_2.0) is required by netcat-0.7.1-1.i386
    libc.so.6(GLIBC_2.1) required by netcat-0.7.1-1.i386
    libc.so.6(GLIBC_2.3) required by netcat-0.7.1-1.i386

The GPG key of CentOS was originally required

To   http://centos.ustc.edu.cn/centos/7/os/x86_64 /, download and import the corresponding GPG key to solve the problem（ This machine is rpm-gpg-key-centos-7)

Then import with GPG command:

[cos@localhost Desktop]$ gpg --quiet --with-fingerprint ./RPM-GPG-KEY-CentOS-7 
gpg: A new configuration file '/home/cos/.gnupg/gpg.conf' has been created
gpg: Warning: The options in '/home/cos/.gnupg/gpg.conf' were not used during this run
pub  4096R/F4A80EB5 2014-06-23 CentOS-7 Key (CentOS 7 Official Signing Key) <[email protected]>
Key Fingerprint = 6341 AB27 53D7 8A78 A7C2  7BB1 24C6 A8A7 F4A8 0EB5

 

Import the RPM package of netcat again to succeed:

[cos@localhost Desktop]$ rpm netcat-0.7.1-1.i386.rpm

How to Solve Error: Specifies multiple packages

rpm -qa | grep mysql
mysqlclient10-3.23.58-4.RHEL4.1
mysql-4.1.20-2.RHEL4.1
mysql-4.1.20-2.RHEL4.1
mysqlclient10-3.23.58-4.RHEL4.1

Try uninstalling.

rpm -e mysqlclient10-3.23.58-4.RHEL4.1
error: “mysqlclient10-3.23.58-4.RHEL4.1″ specifies multiple packages

With man rpm, it turns out that -allmatches should fix the problem:.

–allmatches
Remove all versions of the package which match PACKAGE_NAME. Normally an error is issued if PACKAGE_NAME matches
multiple packages.

rpm -e –allmatches mysqlclient10-3.23.58-4.RHEL4.1
rpm -e –allmatches mysql-4.1.20-2.RHEL4.1
warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave

ok, the old version of MySQL that comes with the system is uninstalled.
