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  
  4.   
  5. 1.本实验环境  
  6.   
  7. [root@master ~]# uname  -r

  25. 进入页面https://www.percona.com/downloads/XtraBackup/LATEST/下载操作系统对应的XtraBackup版本  
  26.

  52.   
  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  
  58. warning: percona-xtrabackup-2.3.4-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY

  61.         perl(DBD::mysql) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64  
  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  
  65.   
  66. [root@master ~]# yum install  libev.so.4
