解决安装XtraBackup出现"libev.so.4()(64bit) is needed"问题

尝试安装XtraBackup的时候并没有官方提供的文档安装这么顺利，在安装过程中出现各种缺失的组件和模块需要补充安装。其中中有报错”libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.6-2.el6.x86_64″。应该是缺少libev.so.4。

wget http://rpmfind.net/linux/centos/7.5.1804/extras/x86_64/Packages/libev-4.15-7.el7.x86_64.rpm

rpm -ivh libev-4.15-7.el7.x86_64.rpm

yum -y install https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.4/binary/redhat/6/x86_64/percona-xtrabackup-24-2.4.4-1.el6.x86_64.rpm
