MySQL/MariaDB/Percona数据库升级脚本

MySQL/MariaDB/Percona数据库升级脚本

MySQL/MariaDB/Percona数据库升级脚本截取《OneinStack》中upgrade_db.sh，一般情况下不建议升级数据库版本，该脚本专提供给各位版本控们。为防止大版本之间兼容问题，脚本默认仅支持同一大版本之间的升级，如：MySQL-5.6.25升级到MySQL-5.6.26、MySQL-5.5.44升级到MySQL-5.5.45、MariaDB-10.0.20升级到MariaDB-10.0.21；不能跨分支版本且不能跨大版本，如从MySQL-5.5.44升级到PerconaL-5.5.44-37.3、MySQL-5.5.44升级到MySQL-5.6.25。

2015-07-16之前版本如何支持数据库版本升级？

《OneinStack》：

cd /root/
cp oneinstack/options.conf ~ #备份options.conf
rm -rf oneinstack #删除旧版
wget http://mirrors.linuxeye.com/oneinstack-full.tar.gz #下载最新版
tar xzf oneinstack-full.tar.gz
/bin/mv ~/options.conf ./oneinstack #还原options.conf, 必须使用旧版options.conf文件
cd oneinstack
./upgrade db #升级数据库版本，如下图：

《lnmp一键安装包》：

cp lnmp/options.conf ~ #备份options.conf
rm -rf lnmp #删除旧版
wget http://mirrors.linuxeye.com/lnmp-full.tar.gz #下载最新版
tar xzf lnmp-full.tar.gz
/bin/mv ~/options.conf ./lnmp #还原options.conf, 必须使用旧版options.conf文件
cd lnmp
./upgrade db #升级数据库版本

PS：MySQL/MariaDB/Percona数据库升级脚本内容如下（cat upgrade_db.sh）：
