二进制tar包方式安装Percona Server
Installing Percona Server from a Binary Tarball
1 下载二进制tar包
以5.6版本为例,去官网https://www.percona.com/downloads/Percona-Server-5.6/LATEST/也可以看到如下：
#在Version下拉框中选择具体的percona server的版本
#在Software下拉框中选择对应的OS版本或者二进制tar包或者源码下载
#此处下载5.6最后一个版本，如下：
由上图发现，当选择了版本和下载方式（二进制tar包）后，下方显示了不止一个对应的tar包，而他们不同的地方是：ssl098、ssl100、ssl101.他们的区别如下：
- ssl100 - for all Debian/ versions except Debian Squeeze (libssl.so.1.0.0 =>/usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007f2e389a5000));
- ssl098 - only for Debian Squeeze (libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8(0x00007f9b30db6000));
- ssl101 - for 6 and CentOS 7 (libssl.so.10 => /usr/lib64/libssl.so.10(0x00007facbe8c4000));
- ssl098e - to be used only for CentOS 5 (libssl.so.6 => /lib64/libssl.so.6(0x00002aed5b64d000)).
此处选择安装到RHEL6，下载ssl101对应的tar包
2 解压tar包
#创建basedir
# mkdir /data/percona
#解压
# tar -zxvf Percona-Server-5.6.29-rel76.2-Linux.x86_64.ssl101.tar.gz -C /data/percona/
# cd /data/percona/
# mv Percona-Server-5.6.29-rel76.2-Linux.x86_64.ssl101/ mysql
#最终安装到/data/percona/mysql/目录
# ls /data/percona/mysql/
# chown mysql:mysql /data/percona/mysql/ -R
3 编辑配置文件
#默认读取/etc/my.cnf，此处实验环境已经存在其他mysql实例，初始化和启动的时候都使用 --defaults-file=/tmp/my.cnf 参数来指定配置文件
# cat /tmp/my.cnf
[mysqld]
basedir=/data/percona/mysql
datadir=/data/percona/mysql/data
socket=/data/percona/mysql/mysql.sock
log-error=/data/percona/mysql/mysqld.log
innodb_buffer_pool_size = 128M
port=6603
4 初始化db
#由于本地存在别的mysql实例，此处认为指定cnf路径
# ./scripts/mysql_install_db --defaults-file=/tmp/my.cnf
5 启动percona mysql
# /data/percona/mysql/bin/mysqld_safe --defaults-file=/tmp/my.cnf &
160504 10:37:02 mysqld_safe Adding '/data/percona/mysql/lib/mysql/libjemalloc.so.1' to LD_PRELOAD for mysqld
160504 10:37:02 mysqld_safe Logging to '/data/percona/mysql/mysqld.log'.
160504 10:37:02 mysqld_safe Starting mysqld daemon with databases from /data/percona/mysql/data
6 查看进程
# netstat -antpl|grep mysqld
tcp 0 0 :::6603 :::* LISTEN 17835/mysqld #percona mysql
tcp 0 0 :::3306 :::* LISTEN 23233/mysqld #默认运行的mysql
7 查看log
# tail -f /data/percona/mysql/mysqld.log

至此，percona的二进制tar包的安装简单完成，发现跟mysql的安装几乎一样，关于配置文件的更多选项配置、启动脚本配置以及一些后续的配置等都类似mysql的即可。
8 卸载percona server
1. Stop the Percona Server service
#此处由于有其他默认的mysql实例在运行的原因，需要指定当前sock位置和端口
~#/data/percona/mysql/bin/mysqladmin -S /data/percona/mysql/mysql.sock -P 6603 shutdown
2. Remove the data and configuration files
#直接删除basedir和datadir即可
~# rm -rf /data/percona/mysql/
Percona Server 使用了一些 google-mysql-tools, Proven Scaling, Open Query 对 MySQL 进行改造。
