系统centos7及以上版本

　　

安装依赖包：

yum install perl-IO-Socket-SSL perl-DBD-MySQL perl-Time-HiRes socat nc -y

yum install –y openssl openssl-develxtrabackup

如果提示已经安装，可以使用

#updatedb

#locate libssl.so 看看能不能找到 然后用

# ldd /usr/local/mysql/bin/mysqld 查看还有那些依赖需安装安装：

rpm -qa|grep openssl

yum localinstall percona-xtrabackup-24-2.4.9-1.el6.x86_64.rpm

vim /etc/ld.so.conf.d/mysql.conf
