二进制包安装（推荐安装方式，不用安装依赖包，非常方便）：
1、下载安二进制包：
wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.7/binary/tarball/percona-xtrabackup-2.4.7-Linux-x86_64.tar.gz
2、解压并创建软连接：
# tar zxvf percona-xtrabackup-2.4.7-Linux-x86_64.tar.gz
# mv percona-xtrabackup-2.4.7-Linux-x86_64 /usr/local/xtrabackup
# ln -s /usr/local/xtrabackup/bin/* /usr/bin/
3、查看版本：
# xtrabackup --version
xtrabackup version 2.4.7 based on MySQL server 5.7.13 Linux (x86_64) (revision id: 6f7a799)
源码安装：
1、安装依赖包：
yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bison libtool ncurses-devel
libgcrypt-devel libev-devel libcurl-devel vim-common
libev-devel 包yum安装不上时，可手动RPM包安装
rpm -ivh glibc-2.12-1.166.el6.x86_64.rpm
rpm -ivh libev-4.03-3.el6.x86_64.rpm libev-devel-4.03-3.el6.x86_64.rpm
2、解压源码包：
tar -zxvf percona-xtrabackup-2.3.3.tar.gz
cd percona-xtrabackup-2.3.3
3、编译安装：
cmake -DBUILD_CONFIG=xtrabackup_release -DWITH_MAN_PAGES=OFF && make -j4
make install
4、添加到基本命令：
cp /usr/local/xtrabackup/bin/innobackupex /usr/bin
cp /usr/local/xtrabackup/bin/xtrabackup /usr/bin
yum源安装：
1、安装Percona的库：
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm
2、测试Percona库：
yum list|grep percona
3、安装包：
yum install percona-xtrabackup
