MySQL对libaio库有依赖关系，如果没有这个包，数据目录初始化和接下来的服务启动会失败。
yum install libaio

创建软件安装目录
mkdir /mysql_software_57

下载软件
Percona官网的下载页面有两个二进制Tar包，分别对应不同的发行版本
ssl100 - Debian/Ubuntu
ssl101 - for CentOS 6 and CentOS 7
cd /mysql_software
wget https://www.percona.com/downloads/Percona-Server-5.7/Percona-Server-5.7.17-11/binary/tarball/Percona-Server-5.7.17-11-Linux.x86_64.ssl101.tar.gz

解压安装包
[root@localhost mysql_software_57]# tar xvfz Percona-Server-5.7.17-11-Linux.x86_64.ssl101.tar.gz
[root@localhost mysql_software_57]# ls

[root@localhost mysql_software_57]# rmdir Percona-Server-5.7.17-11-Linux.x86_64.ssl101/

创建mysql用户
[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -r -g mysql -s /bin/false mysql

创建数据目录和日志目录
[root@localhost mysql_software_57]# mkdir /mysql_data_57
[root@localhost mysql_software_57]# mkdir /mysql_log_57

[root@localhost mysql_software_57]# chmod 750 /mysql_data_57/

[root@localhost mysql_software_57]# chown -R mysql.mysql /mysql_data_57/
[root@localhost mysql_software_57]#chown -R mysql.mysql /mysql_log_57/
