这篇文章是我们自己亲手实验过的，系统为 Ubuntu 14.04 server，Mysql 数据库为 Mysql 5.5，准备迁移到 Maria DB 10.1 版本，关于其他版本的迁移方法详细的说明你可以去官方查看，这里我只说说我所实验过的。
关于为什么迁移到 MariaDB，知道 Oralce 收购 Sun 的用户应该知道，当然这已经是几年以前的事情了，本人一直不是很喜欢Oracle在MySQL上面的态度，自己要是安装数据库基本上都会使用 MariaDB。整个迁移过程基本无痛，也没什么需要特别设置的，兼容性非常不错。
首先先到MariaDB官方选择一个合适的源，，然后把给出来的地址放到 /etc/apt/sources.list 文件底部：
# MariaDB 10.1 repository list - created 2014-11-17 01:55 UTC
#
deb trusty main
deb-src trusty main
保存，然后输入以下几条命令：
sudo apt-get install software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db
sudo apt-get update
sudo apt-get install mariadb-server
安装命令会自动卸载 Mysql 数据库！安装过程中会要求你重新设置密码，按照提示操作就可以了，phpmyadmin也是默认支持的！
在 CentOS/RHEL/Scientific Linux 6 下安装 LAMP (Apache with MariaDB and PHP)

Explain the differences between InnoDB and MyISAM storage engines.Apr 27, 2025 am 12:20 AMInnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.
What are the different types of JOINs in MySQL?Apr 27, 2025 am 12:13 AMThere are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

What are some common security vulnerabilities in MySQL?Apr 26, 2025 am 12:27 AMCommon security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.
How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AMIdentifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.
