假設(shè)原來是mysql 5.6.19社區(qū)版，現(xiàn)在要升級到percona server 5.6.30。

對于大的數(shù)據(jù)庫來說，采用mysqldump方式進(jìn)行遷移太花費時間了，可采用新安裝加載原來數(shù)據(jù)庫的方式大大節(jié)約升級時間。

對于mysql升級來說，一個主要的步驟就是升級后權(quán)限的同步更新以及數(shù)據(jù)表的校驗。

假設(shè)原來為/usr/local/mysql->?mysql-5.6.19-linux-glibc2.5-x86_64，數(shù)據(jù)庫在data目錄下。

0、停止現(xiàn)有實例，/usr/local/mysql/bin/mysqladmin -u -p shutdown?

1、首先，刪除原來的符號鏈接rm rf /usr/local/mysql；

2、解壓Percona-Server-5.6.30-rel76.3-Linux.x86_64.ssl101.tar.gz到當(dāng)前目錄；

3、創(chuàng)建新的符號鏈接ln -s Percona-Server-5.6.30-rel76.3-Linux.x86_64.ssl101?mysql

4、更改my.cnf，去掉datadir、basedir注釋，如下：

??? basedir = /usr/local/mysql?#指向最新的mysql實例

??? datadir = /usr/local/mysql-5.6.19-linux-glibc2.5-x86_64/data?指向原來的mysql數(shù)據(jù)庫目錄

????其他配置可以保持不變。。。

5、使用新的安裝包創(chuàng)建啟動mysql實例：/usr/local/mysql/bin/mysqld_safe --user=mysql &

6、執(zhí)行mysql_upgrade

7、重啟mysql實例。

8、客戶端驗證，可發(fā)現(xiàn)所有數(shù)據(jù)和存儲過程均正常。
