XtraBackup backup appears "Can't locate Digest/MD5.pm in @ INC", xtrabackupm5.pm

 

Xtrabackup 2.4.5 (innobackupex version 2.4.5 Linux (x86_64) (revision id: e41c0be) is installed on CentOS 7 )), the following error message "Can't locate Digest/MD5.pm in @ INC (@ INC contains: /usr/local/lib64/perl5/usr/local/share/perl5/usr/lib64/perl5/vendor_perl/usr/share/perl5/vendor_perl/usr/lib64/perl5/usr /share/perl5 .) at-line 693 ". The error message is as follows:

IMPORTANT: Please check that the backup run completes successfully.

           At the end of a successful backup run innobackupex

           prints "completed OK!".

This error occurs because the perl-Digest-MD5 component is not installed when Xtrabackup 2.4.5 is installed. Percona official information does not include the latest Percona XtraBackup 2.4 Documents, only Percona XtraBackup 2.2 Documentation, Release 2.2.13. This document does not require installation of components. I only installed the following components.

[root@DB-Server ~]# yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bzr \

                    bison libtool ncurses5-devel

[root@DB-Server ~]# yum -y install perl perl-devel perl-Time-HiRes perl-DBD-MySQL

After installing the perl-Digest-MD5, the problem can be solved.

[root@DB-Server ~]# yum -y install perl-Digest-MD5
