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 | +------------+ 1 row in set (0.00 sec) 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 --2016-05-17 12:42:14-- 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 Resolving www.percona.com... 74.121.199.234 Connecting to www.percona.com|74.121.199.234|:443... connected.
