    在CentOS 7上安装了Xtrabackup 2.4.5(innobackupex version 2.4.5 Linux (x86_64) (revision id: e41c0be)),然后做备份时遇到下面错误信息“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”。 具体错误提示信息如下:

170222 10:57:29 innobackupex: Starting the backup operation

 

IMPORTANT: Please check that the backup run completes successfully.

           At the end of a successful backup run innobackupex

           prints "completed OK!".

xtrabackup:   innodb_log_files_in_group = 2

xtrabackup:   innodb_log_file_size = 50331648

 

出现这个错误是因为安装Xtrabackup 2.4.5时,没有安装 perl-Digest-MD5组件。Percona官方文档里面介绍了使用yum、apt等安装方式,没有详细介绍使用rpm安装方式。这个文档里并没有要求安装组件perl-Digest-MD5。而我只安装了下面一些组件。

[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

安装了perl-Digest-MD5后,问题即可解决。

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