关于percona-xtrabackup 安装的小纠结

今天本来打算小装一个percona的xtrabackup来测试一把MySQL热备的实验，然后就在percona官网下载了一个最新版的2.4.6版本的xtrabackup

然后先在Redhat 6.4系统上进行安装，将包传上去以后解压安装，然而报了

然后就在Google上查了一下：

https://bugs.launchpad.net/percona-xtrabackup/+bug/1526636

中介绍了关于xtrabackup安装的一个bug

Bug Description

When installing the latest release of percona-xtrabackup (2.3.2-1) from the percona repo, it encounters a missing dependency for libev.so.

Error: Package: percona-xtrabackup-2.3.2-1.el6.x86_64 (percona)
           Requires: libev.so.4()(64bit)

This can be resolved by installing an external repo such as EPEL, but probably should be included in the percona repo. Alternatively switching to AnyEvent (if EV is not a hard requirement) would allow for EV or the internal loop if EV is not installed on a system.

Have not tested this issue with other releases of CentOS.

所以就在Google上找了一个相关的依赖包：libev-4.15-1.el6.rf.x86_64.rpm

安装完毕以后还是报了如下的依赖包的错：

[root@server2 software]# rpm -ivh percona-xtrabackup-24-2.4.6-2.el6.x86_64.rpm

但是在/usr/lib64的目录下是有这两个文件的啊

[root@cxqtest ~]# ls /usr/lib64/|grep -e ssl.so -e crypto.so
libcrypto.so.10
libcrypto.so.1.0.1e
libnss_compat_ossl.so.0
libnss_compat_ossl.so.0.0.0
libssl.so.10
libssl.so.1.0.1e

查了各种资料，重新安装了openssl依赖包，然而并没有什么卵用。

索性换了一台虚机是centos 6.5的系统再一次尝试：

然后就ok了！
