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
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]# tar xvfz Percona-Server-5.7.17-11-Linux.x86_64.ssl101.tar.gz
建立软链接
[root@localhost mysql_software]# ln -s Percona-Server-5.7.17-11-Linux.x86_64.ssl101 data
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
[root@localhost ~]# mkdir /mysql_data
[root@localhost ~]# chmod 750 /mysql_data/
[root@localhost ~]# chown -R mysql /mysql_data/
[root@localhost ~]# chgrp -R mysql /mysql_data/
[root@localhost /]# chown -R mysql /mysql_software/Percona-Server-5.7.17-11-Linux.x86_64.ssl101

[root@localhost /]# chgrp -R mysql /mysql_software/Percona-Server-5.7.17-11-Linux.x86_64.ssl101

初始化MySQL数据库的数据文件路径，并且创建系统表

[root@localhost ~]# cd /mysql_software/Percona-Server-5.7.17-11-Linux.x86_64.ssl101

[root@localhost Percona-Server-5.7.17-11-Linux.x86_64.ssl101]# bin/mysqld --initialize-insecure --user=mysql --basedir=/mysql_software/Percona-Server-5.7.17-11-Linux.x86_64.ssl101 --datadir=/mysql_data

#./bin/mysqld --defaults-file=/opt/mysql_5.7.17/etc/my.cnf --initialize-insecure --user=mysql(配置文件初始化)

查看日志，若没有配置日志，则会将信息输出到屏幕

[root@localhost Percona-Server-5.7.17-11-Linux.x86_64.ssl101]# cat log/mysqld_0.log

如果配置文件中没有指定数据文件的路径，默认路径是/var/lib/mysql
如果在配置文件/etc/my.cnf中指定了数据文件的路径，则会根据这个路径进行生成
