Percona 为 MySQL 数据库服务器进行了改进，在功能和性能上较 MySQL 有着很显著的提升。该版本提升了在高负载情况下的 InnoDB 的性能、为 DBA 提供一些非常有用的性能诊断工具；另外有更多的参数和命令来控制服务器行为。
2、特点 Percona Server 只包含 MySQL 的服务器版，并没有提供相应对 MySQL 的 Connector 和 GUI 工具进行改进。
Percona Server 使用了一些 google-mysql-tools, Proven Scaling, Open Query 对 MySQL 进行改造。
3、版本发布 2012年08月15日，Percona Server 5.6 Alpha 发布。
2012年08月23日，Percona Server 5.5.27-28.0 发布。
2013年04月11日，Percona Server for MySQL 5.5.30-30.2 发布

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h mysql2 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.

Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

二、配置Percona-Server
[root@mysql2 soft]# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[root@mysql2 soft]# vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
explicit_defaults_for_timestamp=true
innodb_buffer_pool_size = 128M
join_buffer_size = 128M
sort_buffer_size = 2M
read_rnd_buffer_size = 2M
启动mysql服务：
[root@mysql2 soft]# service mysql start
/usr/bin/my_print_defaults: /usr/lib/libcrypto.so.10: no version information available (required by /usr/bin/my_print_defaults)
Starting MySQL (Percona Server).....[ OK ]
[root@mysql2 soft]# netstat -an |grep :3306
tcp 0 0 :::3306 :::* LISTEN
修改root密码：
[root@mysql2 soft]# mysqladmin -u root password "oracle"
mysqladmin: /usr/lib/libcrypto.so.10: no version information available (required by mysqladmin)
mysqladmin: /usr/lib/libssl.so.10: no version information available (required by mysqladmin)
Warning: Using a password on the command line interface can be insecure.
连接数据库：
[root@mysql2 soft]# mysql -u root -p
mysql: /usr/lib/libcrypto.so.10: no version information available (required by mysql)
mysql: /usr/lib/libssl.so.10: no version information available (required by mysql)
Enter password:

MySQL conflicts with mysql-5.1.66-2.el6_3.x86_64
卸载原有的mysql：
[root@rh6 oracle]#rpm -qa |grep mysql

[root@rh6 oracle]#rpm -e mysql-5.1.66-2.el6_3.x86_64
安装openssl：
下载openssl-1.0.1：

openssl-devel-1.0.0-27.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。
2、解决“/usr/lib/libcrypto.so.10: no version information available ” [root@mysql2 soft]# rpm -qa |grep openssl
openssl-1.0.1e-42.el6.x86_64
openssl-1.0.0-27.el6.x86_64
