note_21.4.1_LAMP

LAMP:

httpd:接收用户的web请求;静态资源则直接响应;动态资源为php脚本,对此类资源的请求将交由php来运行;
php:运行php程序;
MariaDB:数据管理系统;

httpd与php结合的方式:
    FastCGI 
    modules (把php编译成为httpd的模块)
        MPM:
            prefork: libphp5.so
            event, worker: libphp5-zts.so

安装lamp:

CentOS 6: httpd, php, mysql-server, php-mysql
    # service httpd  start
    # service  mysqld  start
CentOS 7: httpd, php, php-mysql, mariadb-server
    # systemctl  start  httpd.service
    # systemctl  start  mariadb.service

php:

脚本语言解释器
配置文件:/etc/php.ini, /etc/php.d/*.ini

配置文件在php解释器启动时被读取,因此,对配置文件的修改如何生效?
Modules:重启httpd服务;
FastCGI:重启php-fpm服务;

ini:
    [foo]:Section Header
    directive = value
                        
    php.ini的核心配置选项文档:  http://php.net/manual/zh/ini.core.php
    php.ini配置选项列表:http://php.net/manual/zh/ini.list.php
                        

MariaDB

主要有两类程序文件
Client: mysql, mysqldump, mysqladmin
Server:mysqld, mysqld_safe, mysqld_multi

MySQL的命令行客户端程序:mysql
        -u 
        -h
        -p
                
命令的种类:
    客户端命令:
        mysql> help
    服务端命令:
                
        支持SQL语句对数据管理:
            DDL,DML
                DDL: CREATE, ALTER, DROP, SHOW
                DML: INSERT, DELETE,SELECT, UPDATE
                            
        授权能远程的连接用户:
            mysql> GRANT  ALL  PRIVILEGES  ON  db_name.tbl_name TO  username@host  IDENTIFIED BY 'password'; 

php测试代码


php连接mysql的测试代码:

  

实践作业:部署lamp,以虚拟主机安装wordpress, phpwind, discuz;
