问题描述：
服务器操作系统是CentOS 5.5，此前已经有多套系统跑在上面，且装有PHP5.2.10。Centos5.X系统的稳定yum安装源版本是5.1.6，并不符合最新版本的phpmyadmin(5.2以上版本)，下载了最新版本phpmyadmin安装后提示缺少mysql支持模块。查看了一下发现的确是安装php的时候没有装上php-mysql模块。直接重新编译php源码安装比较麻烦。
一个比较方便的方法：
为yum添加第三方的源，然后直接用yum -y install php-mysql进行安装
以下方法为从网络搜索到的，做个记录，方面须用之时查阅。
导入地址： rpm --import
编辑yum源： vi /etc/yum.repos.d/CentOS-Base.repo
在最下面添加如下信息：
[utterramblings]
name=Jason's Utter Ramblings Repo
baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
然后执行安装命令： yum -y install php-mysql 系统就会自动从上面添加的源中读取合适该版本的php-mysl模块，，安装完成后重启httpd服务，再访问就OK了。
该方法同样适合于默认安装的php5.1.6版本安装成功后再进行升级到 5.2版本。
How does MySQL's licensing compare to other database systems?Apr 25, 2025 am 12:26 AMMySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.
When would you choose InnoDB over MyISAM, and vice versa?Apr 25, 2025 am 12:22 AMThe situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.
Explain the purpose of foreign keys in MySQL.Apr 25, 2025 am 12:17 AMIn MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.
What are the different types of indexes in MySQL?Apr 25, 2025 am 12:12 AMThere are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

What are indexes in MySQL, and how do they improve performance?Apr 24, 2025 am 12:09 AMIndexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid
Explain how to use transactions in MySQL to ensure data consistency.Apr 24, 2025 am 12:09 AMUsing transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
