rpm包方式安裝Percona Server

Percona XtraDB是 InnoDB 儲存引擎的增強版，被設計用來更好的使用更新電腦硬體系統的效能，同時還包含有一些在高效能環境下的新特性。XtraDB 儲存引擎是完全的向下相容，於是完全可以使用XtraDB來替代InnoDB儲存引擎。

Percona XtraDB 包含有所有 InnoDB's 健壯性，可依賴的 ACID 相容設計和進階 MVCC 架構。XtraDB 在 InnoDB 的堅實基礎上構建，使 XtraDB 具有更多的特性，更好調用，更多的參數指標和更多的擴充。

尤其是，XtraDB 被設計用來在多核心的條件下更有效使用記憶體和更加方便，更加可用。也解除了InnoDB的很多限制；提供了比InnoDB更多的配置和效能監控參數。

Percona XtraDB engine包含在Percona Server and MariaDB中。

Installing Percona Server on Red Hat Enterprise Linux

Percona Server跟MySQL一樣有多種安裝方法：yum Repositories、rpm、Binary Tarball、Source Tarball、Git Source Tree等，可以根據實際環境選擇，具體安裝步驟請參考官方文檔。下文主要以rpm包在RHEL 6上的安裝為例說明主要步驟

Installing Percona Server using rpm packages1下載軟體包

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 解壓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 安裝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

#以上三個rpm包僅僅為了完成Percona server的安裝

#若需要（包含debugging, testing,etc等）,則直接安裝所有的rpm包即可

#rpm -ivh *.rpm

附：RHEL6上安裝報錯：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

#RedHat EL6內建openssl-1.0.0版本，對於Percona-Server應該安裝openssl-1.0.1的版本，安裝新版本後，問題解決

# 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 設定檔

Percona Server預設的資料檔案路徑在/var/lib/mysql/下

#編輯設定檔/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

註：設定檔有很多選項，具體的根據實際需求配置，此處只是簡單配置了下而已

5 運行Percona Server1. Starting the service

# /etc/init.d/mysql start

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

2. Confirming that service is running

# /etc/init.d/mysql status

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 \

3. Remove the data and configuration files

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

註：這裡將刪除所有的資料檔案（databases, tables, logs, etc.），可能你環境中的datafile的位置並不是預設的/var/lib/mysql，而是其他的目錄，卸載的時候根據實際情況刪除檔案
