Apache
作者:vipcui
一、系统要求:
本系统在REDHAT7.2版本测试通过
二、服务器端软件要求:
1:到APACHE的网络站下载APACHE WEB SERVER http://www.apache.org/
2. 到php的网络站下载php解析器 http://www.php.net/
3.到mysql的网站下载 mysql http://sourceforge.net/projects/mysql/
三.安装调试WEB SERVER
把以上各文件下载后放到同一个目录下,我把他们放在/usr/local下,用tar命令把个文件解包
tar zxvf apache_1.3.12.tar.gz
tar zxvf php-4.0.6.tar.gz
tar zxvf mysql-3.22.40.tar.gz
为了便于安装建议把目录该名字
#mv apache_1.3.12 apache
#mv php-4.0.6 php
#mv mysql-3.22.40 mysql
安装mysql
四.在安装web服务前可以先安装mysql
cd mysql
./configure
make
make install
根据机子的性能,编译过程要花费一定的时间,编译完成后系统默认把mysql安装在/usr/local下。
安装完成后,先把mysql的进程启起来
cd /usr/local/bin
./mysql_install_db(安装mysql的基本数据库)
./safe_mysqld & (把进程启起来并转入后台)
到这里mysql算安装完成了,试试运行./mysql看看能不能链接数据库,如果正常的话,应该可以看到这样的界面
Welcome to the MySQL monitor.Commands end with ; or g.
Your MySQL connection id is 880 to server version: 3.22.40
Type 'help' for help.
mysql>
到这恭喜你完成了mysql的安装
mysql的使用大家可以参照他的doc文档
五.
整合apache、php4
这是所有工作的关键所在,也是最难的一步,可能因为版本的不同在安装过程中有这样那样的错误,大家可以根据版本信息作出相应的修改。
先cd apache
./configure
这一步好象可有可无,可是我曾经因为没有作这一步而出错所以必须有这一步
cd ../php
./configure --with-mysql=/usr/local --with-apache=/usr/local/apache --enable-track-vars
make
make install
cd ../apache
./configure --activate-module=src/modules/php4/libphp4.a
make
make install
这步是安装apache WEB服务,大家可以看看./configure –help自己加入相应需要的模块,或者参照安装手册进行安装。
把php的配置文件拷贝到相应的目录下
cd ../php
cp php.ini-dist /usr/local/lib/php.ini
php.ini基本可以不用作什么修改,要修改可以参照相应的说明。
配置完PHP就该配置Apache Web SERVER了,先对httpd.conf进行配置
cd /usr/local/apache/conf
vi httpd.conf
针对php要对以下内容进行修改:
# AddType application/x-httpd-php .php
# AddType application/x-httpd-php-source .phps
把以上两行的注释符去掉,并根据实际情况确定php文档的后缀名,根据horde的需要,建议大家把第一行改成如下形式
AddType application/x-httpd-php .php .php3 .htm .phtml .php4
另外还要修改系统默认的首页类型,建议把
DirectoryIndex index.htm
改成这样
DirectoryIndex index.htm index.html index.php3 index.php default.php

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
