今天使用 innobackupex备份初始化环境时报错如下：
-bash-4.1$ innobackupex -help
Can't locate Time/HiRes.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 /data/mysql/tool/percona-xtrabackup-2.2.10-Linux-x86_64/bin/innobackupex line 24.
BEGIN failed--compilation aborted at /data/mysql/tool/percona-xtrabackup-2.2.10-Linux-x86_64/bin/innobackupex line 24.

解决方法：
1.挂载光驱，
2.配置yum源为本地
[root@centos1 yum.repos.d]# pwd
/etc/yum.repos.d
[root@centos1 yum.repos.d]# more CentOS-Media.repo
# CentOS-Media.repo
#
#  This repo can be used with mounted DVD media, verify the mount point for
#  CentOS-6.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c6-media [command]
# 
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=c6-media [command]
 
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cdrom/
gpgcheck=0
enabled=1
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
[root@centos1 yum.repos.d]#

3.安装 perl-Time-HiRes

[root@centos1 Packages]# yum install perl-Time-HiRes

5.查看是否正常：

-bash-4.1$ ./innobackupex -help
Options:
    --apply-log
        Prepare a backup in BACKUP-DIR by applying the transaction log file
        named "xtrabackup_logfile" located in the same directory. Also,
        create new transaction logs. The InnoDB configuration is read from
        the file "backup-my.cnf".

    --backup-locks
        This option controls if backup locks should be used instead of FLUSH
        TABLES WITH READ LOCK on the backup stage. The option has no effect
        when backup locks are not supported by the server. This option is
