• LAMP介绍和部署流程


    lamp介绍和部署流程

    lamp简介

    • lamp其实就是由Linux+Apache+Mysql/MariaDB+Php/Perl/Python的一组动态网站或者服务器的开源软件,除Linux外其它各部件本身都是各自独立的程序,但是因为经常被放在一起使用,拥有了越来越高的兼容度,共同组成了一个强大的Web应用程序平台。

    • LAMP指的是Linux(操作系统)、Apache(HTTP服务器)、MySQL(也指MariaDB,数据库软件)和PHP(有时也是指Perl或Python)的第一个字母,一般用来建立web应用平台。

    web服务器工作流程

    web服务器

    web服务器的资源分为两种,静态资源和动态资源

    • 静态资源就是指静态内容,客户端从服务器获得的资源的表现形式与原文件相同。可以简单的理解为就是直接存储于文件系统中的资源
    • 动态资源则通常是程序文件,需要在服务器执行之后,将执行的结果返回给客户端

    web工作流程

    • 客户端通过http协议请求web服务器资源
    • web服务器收到请求后判断客户端请求的资源是静态资源或是动态资源
      • 若是静态资源则直接从本地文件系统取之返回给客户端。
      • 否则若为动态资源则通过FastCGI协议与php服务器联系,通过CGI程序的master进程调度worker进程来执行程序以获得客户端请求的动态资源,并将执行的结果通过FastCGI协议返回给httpd服务器,httpd服务器收到php的执行结果后将其封装为http响应报文响应给客户端。在执行程序获取动态资源时若需要获得数据库中的资源时,由Php服务器通过mysql协议与MySQL/MariaDB服务器交互,取之而后返回给httpd,httpd将从php服务器收到的执行结果封装成http响应报文响应给客户端。

    lamp平台构建

    环境说明:

    系统平台 IP 需要安装的服务
    redhat8 192.168.110.133 httpd-2.4 mysql-5.7 php php-mysql

    lamp平台软件安装次序:

        httpd --> mysql --> php

    [root@192 ~]# echo 'T%&qOEqnN1UZ' > a //把密码保存到a等下方便查看
    
    1. 配置mysql
    [root@192 ~]# vim /etc/my.cnf
    
    [mysqld]
    basedir = /usr/local/mysql   
    datadir = /opt/data
    socket = /tmp/mysql.sock
    port = 3306
    pid-file = /opt/data/mysql.pid
    user = mysql
    skip-name-resolve
    //配置以上8行配置
    #
    # This group is read both both by the client and the server
    # use it for options that affect everything
    #
    [client-server]
    
    #
    # include all files from the config directory
    #
    !includedir /etc/my.cnf.d
    
    1. 配置服务启动脚本
    [root@192 ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
    [root@192 ~]# vim /etc/init.d/mysqld
    
    basedir=/usr/local/mysql
    datadir=/opt/data
    
    1. 启动mysql
    [root@192 ~]# service mysqld start
    Starting MySQL.Logging to '/opt/data/192.168.110.133.err'.
     SUCCESS! 
    [root@192 ~]# ss -antl  //可以看到3306端口
    State     Recv-Q     Send-Q         Local Address:Port         Peer Address:Port    
    LISTEN    0          128                  0.0.0.0:22                0.0.0.0:*

    [root@192 ~]# 
    
    
    1. 用刚刚的临时密码登录mysql,并设置新密码
    [root@192 ~]# cat a
    T%&qOEqnN1UZ
    [root@192 ~]# mysql -uroot -p'T%&qOEqnN1UZ'
    mysql: [Warning] Using a password on the command line interface can be insecure.

    1. 配置虚拟主机
    [root@192 ~]# vim /etc/httpd24/httpd.conf   //在最后一行加上配置
    <VirtualHost *:80>
        DocumentRoot "/usr/local/apache/htdocs/html"
        ServerName www.leichen.com
        ProxyRequests Off    ProxyPassMatch ^/(.*.php)$ fcgi://127.0.0.1:9000/usr/local/apache/htdocs/html/$1
        <Directory "/usr/local/apache/htdocs/html">
            Options none
            AllowOverride none
            Require all granted
        </Directory>
    </VirtualHost>
    [root@192 ~]# apachectl restart   //重启
    [root@192 ~]# ss -antl
    State     Recv-Q     Send-Q         Local Address:Port         Peer Address:Port    
    LISTEN    0          128                  0.0.0.0:22                0.0.0.0:*       
    LISTEN    0          128                127.0.0.1:9000              0.0.0.0:*

    LISTEN    0          128                        *:80                      *:*       
    LISTEN    0          128                     [::]:22                   [::]:*   
    [root@192 ~]# vim /etc/httpd24/httpd.conf   
       # If the AddEncoding directives above are commented-out, then you
        # probably should define those extensions to indicate media types:
        #
        AddType application/x-compress .Z
        AddType application/x-gzip .gz .tgz
        AddType application/x-httpd-php .php         //添加这行配置
        AddType application/x-httpd-php-source .phps  //添加这行配置
    [root@192 ~]# vim /etc/httpd24/httpd.conf
    # DirectoryIndex: sets the file that Apache will serve if a directory
    # is requested.
    #
    <IfModule dir_module>
        DirectoryIndex index.php index.html  //添加index.php 优先访问前面的
    </IfModule>
    
    
    1. 重启apache服务,关闭防火墙
    [root@192 ~]# apachectl restart
    [root@192 ~]# ss -antl
    State     Recv-Q     Send-Q         Local Address:Port         Peer Address:Port    
    LISTEN    0          128                  0.0.0.0:22                0.0.0.0:*       
    LISTEN    0          128                127.0.0.1:9000              0.0.0.0:*       
    LISTEN    0          80                         *:3306                    *:*       
    LISTEN    0          128                        *:80                      *:*       
    LISTEN    0          128                     [::]:22                   [::]:*       
    [root@192 ~]# systemctl stop firewalld
    [root@192 ~]# setenforce 0
