遇到问题
1、安装percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm 提示缺少lidev.so.4软件包
[root@lineqi opt]# rpm -ivhpercona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm
warning: percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm : Header V4 RSA/SHA256 Signature, key ID 8507efa5: NOKEY
error: Failed dependencies:
libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm
percona的官方提示信息如下
Warning: Make sure that you have the libev package installed before installing Percona XtraBackup on CentOS6. For this operating system, the libev package is available from the EPEL repositories.
说明：在centos6安装Percona XtraBackup时，需要提前安装libev package，这里在centos7也需要，其原因是因为percona-xtrabackup依赖libev.so.4()(64bit)的包，而这个包只能从EPEL源(Extra Packages for Enterprise Linux，企业版Linux的额外软件包 是Fedora小组维护的一个软件仓库项目，为RHEL/CentOS提供他们默认不提供的软件包)安装 ,所以只要安装了这个包即可解决问题.
