- 在mysql主从同步时经常会用到Xtra, XtraBackup可以说是一个相对完美的免费开源数据备份工具,支持在线无锁表同步复制和可并行高效率的安全备份恢复机制相比mysqldump来说优势较大好处多,在RHEL6中安装XtraBackup时会发生缺少依赖包的现象
- 本案例针对Xtra缺少依赖包的情况进行安装分析解决
- 1.本实验环境
- [root@master ~]# uname -r
- 2.6.32-573.el6.x86_64
- [root@master ~]# cat /etc/redhat-release
- Red Hat Enterprise Linux Server release 6.7 (Santiago)
- mysql> select version();
- +------------+
- | version() |
- +------------+
- | 5.6.28-log |
- +------------+

- 2.安装Xtra
- 进入页面https://www.percona.com/downloads/XtraBackup/LATEST/下载操作系统对应的XtraBackup版本
- [root@master ~]# wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.3.4/binary/redhat/6/x86_64/Percona-XtraBackup-2.3.4-re80c779-el6-x86_64-bundle.tar

- 3.安装排错步骤
- 3.1 在安装过程中发现缺少依赖包lib和perl,原则上能用yum解决的就优先用yum解决,yum解决不掉的可以用网上的yum源或者自己单独下载rpm包进行安装
- [root@master ~]# rpm -ivh percona-xtrabackup-2.3.4-1.el6.x86_64.rpm
- warning: percona-xtrabackup-2.3.4-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
- error: Failed dependencies:
- libev.so.4()(64bit) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64
- perl(DBD::mysql) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64
- 3.2 使用本地yum源安装libev与perl-DBI,但libev.so.4安装失败,是由于本地yum源没有该rpm包,我这里使用网上下载的rpm包进行安装
- [root@master ~]# yum install libev.so.4

- Error: Nothing to do
- 3.3 安装perl-DBD-MySQL 成功完成
