Percona XtraDB是 InnoDB 存储引擎的增强版，被设计用来更好的使用更新计算机硬件系统的性能，同时还包含有一些在高性能环境下的新特性。XtraDB 存储引擎是完全的向下兼容，于是完全可以使用XtraDB来替代InnoDB存储引擎。

Percona XtraDB 包含有所有 InnoDB's 健壮性，可依赖的 ACID 兼容设计和高级 MVCC 架构。XtraDB 在 InnoDB 的坚实基础上构建，使 XtraDB 具有更多的特性，更好调用，更多的参数指标和更多的扩展。

尤其是，XtraDB 被设计用来在多核心的条件下更有效的使用内存和更加方便，更加可用。也解除了InnoDB的很多限制；提供了比InnoDB更多的配置和性能监控参数。

Percona XtraDB engine包含在Percona Server and MariaDB中。

Installing Percona Server on Red Hat Enterprise Linux

Percona Server跟MySQL一样有多种安装方法：yum Repositories、rpm、Binary Tarball、Source Tarball、Git Source Tree等，可以根据实际环境选择，具体安装步骤请参考官方文档。下文主要以rpm包在RHEL 6上的安装为例说明主要步骤

InstallingPercona Server using rpm packages

1下载软件包

wget https://www.percona.com/downloads/Percona-Server-5.6/Percona-Server-5.6.29-76.2/binary/redhat/6/x86_64/Percona-Server-5.6.29-76.2-rddf26fe-el6-x86_64-bundle.tar

2解压tar包

]# tar -xvf Percona-Server-5.6.29-76.2-rddf26fe-el6-x86_64-bundle.tar

]# ls *.rpm

Percona-Server-56-debuginfo-5.6.29-rel76.2.el6.x86_64.rpm

Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64.rpm

Percona-Server-tokudb-56-5.6.29-rel76.2.el6.x86_64.rpm

Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64.rpm

Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64.rpm

Percona-Server-devel-56-5.6.29-rel76.2.el6.x86_64.rpm

Percona-Server-test-56-5.6.29-rel76.2.el6.x86_64.rpm

3安装Percona Server

]#rpm -ivh Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64.rpm \

Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64.rpm \

Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64.rpm

#以上三个rpm包仅仅为了完成Percona server的安装

#若需要（包含debugging, testing,etc等）,则直接安装所有的rpm包即可

]#rpm -ivh *.rpm

附：RHEL6上安装报错：libcrypto.so.10和libssl.so.10

error: Failed dependencies:

        libcrypto.so.10(libcrypto.so.10)(64bit) is needed by Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64

        libssl.so.10(libssl.so.10)(64bit) is needed by Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64

        libcrypto.so.10(libcrypto.so.10)(64bit) is needed by Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64

        libssl.so.10(libssl.so.10)(64bit) is needed by Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64

#RedHat EL6自带openssl-1.0.0版本，对于Percona-Server应该安装openssl-1.0.1的版本，安装新版本后，问题解决

]# rpm -ivh openssl10-libs-1.0.1e-1.ius.el6.x86_64.rpm --force

warning: openssl10-libs-1.0.1e-1.ius.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 9cd4953f: NOKEY

4配置文件

Percona Server默认的数据文件路径在/var/lib/mysql/下

#编辑配置文件/etc/my.cnf

]# cat /etc/my.cnf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

log-error=/var/log/mysqld.log

innodb_buffer_pool_size = 128M

注：配置文件有很多选项，具体的根据实际需求配置，此处只是简单配置了下而已

5运行Percona Server

1. Starting the service

]# /etc/init.d/mysql start

Starting MySQL (Percona Server).............[  OK  ]

2. Confirming that service is running

]# /etc/init.d/mysql status

MySQL (Percona Server) running (3369)[  OK  ]

3. Stopping the service

]# /etc/init.d/mysql stop

Shutting down MySQL (Percona Server)..[  OK  ]

4. Restarting the service

]# /etc/init.d/mysql restart

Shutting down MySQL (Percona Server)..[  OK  ]

Starting MySQL (Percona Server).....[  OK  ]

6查看log

]# tail -f /var/log/mysqld.log

7卸载Percona Server

1. Stop thePercona Server service

]# /etc/init.d/mysql stop

Shutting down MySQL (Percona Server)..[  OK  ]

2. Remove the packages

]# rpm -qa|grep -i percona

Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64

Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64

Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64

]# rpm -e Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64 \

 Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64 \

 Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64

]# rpm -qa|grep -i percona

3. Remove the data and configuration files

]# rm -rf /var/lib/mysql/ /etc/my.cnf

注：这里将删除所有的数据文件（databases, tables, logs, etc.），可能你环境中的datafile的位置并不是默认的/var/lib/mysql，而是其他的目录，卸载的时候根据实际情况删除文件
