Solve the problem of "Header V4 DSA/SHA1 Signature\\" when installing xtrabackup

If you need to install the xtrabackup tool, the fastest way is to install it directly with the official rpm. Anyway, the official choice should correspond to the system version of your own server. Do not choose debian when installing centos. System Files. Snail has previously recorded the problem of "solving the problem of "libev.so.4()(64bit) is needed" when installing XtraBackup. The main reason is the lack of necessary component support.

However, when continuing the installation, an error message such as "Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEYerror: Failed dependencies:\\" appeared. There should still be a lack of necessary component support.

rpm -ivh percona-xtrabackup-24-2.4.9-1.el6.x86_64.rpmwarning: percona-xtrabackup-24-2.4.9-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEYerror: Failed dependencies:percona-xtrabackup conflicts with percona-xtrabackup-24-2.4.9-1.el6.x86_64[[email protected] ~]#

The way to solve the problem is to install all the necessary environmental components found online in Gulu, and then execute the rpm installation.

yum install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL -y
