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

时间：2021-10-13 17:20:28
  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. 本案例针对Xtra缺少依赖包的情况进行安装分析解决
  3. 1.本实验环境
  4. [root@master ~]# uname  -r

  37. 3.安装排错步骤
  38. 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
  39. [root@master ~]# rpm -ivh percona-xtrabackup-2.3.4-1.el6.x86_64.rpm
  40. warning: percona-xtrabackup-2.3.4-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
  41. error: Failed dependencies:

  43. perl(DBD::mysql) is needed by percona-xtrabackup-2.3.4-1.el6.x86_64
  44. 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
  45. [root@master ~]# yum install  libev.so.4
