• 解决 libev.so.4()(64bit) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64案例

    1.     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  
    2.   
    3. 本案例针对Xtra缺少依赖包的情况进行安装分析解决

    53. 3.安装排错步骤  
    54.   
    55. 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  
    56.   
    57. [root@master ~]# rpm -ivh percona-xtrabackup-2.3.4-1.el6.x86_64.rpm

    62.           
    63.   
    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
