linux集群架构-LNMP架构

1.什么是LNMP架构

2.LNMP架构是如何工作的

location / {
    index index.php;
}

location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
}

location ~ \.(jpg|png|gif)$ {
    root /code/images;
}

3.nginx与php,mysql之间是如何工作的。

4.如何安装LNMP架构

安装php

配置扩展源

yum localinstall -y http://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装php7.1

yum -y install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb

启动php

systemctl start php-fpm

安装mysql

touch /etc/yum.repos.d/mariadb.repo
然后写入如下内容
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

安装

yum install mariadb-server mariadb -y

启动

systemctl start mariadb

5.nginx与php集成的原理

1.编写能解析的php的nginx配置文件

[root@web01 conf.d]# cat php.oldxu.com.conf 
    server {
        listen 80;
        server_name php.oldxu.com;
        root /code;

        location / {
            index index.php;
        } 

        location ~ \.php$ {
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
        }
    }

5.2.编写PHP代码,测试访问效果.

[root@web01 conf.d]# cat /code/info.php
   <?php
       phpinfo();
   ?>

5.3host劫持

6.php与mysql集成的原理

6.1启动数据库

[root@web01 ~]# systemctl start mariadb

6.2.配置连接密码

[root@web01 ~]# mysqladmin password oldxu.com

6.3测试登录mysql

[root@web01 ~]# mysql -uroot -poldxu.com
MariaDB [(none)]>

6.4编写php连接数据库的代码

[root@web01 ~]# /code/mysqli.php
    <?php
        $servername = "localhost";
        $username = "root";
        $password = "oldxu.com";

        // 创建连接
        $conn = mysqli_connect($servername, $username, $password);

        // 检测连接
        if (!$conn) {
            die("Connection failed: " . mysqli_connect_error());
        }
        echo "php连接MySQL数据库成功";
    ?>

6.5测试

(1)[root@web01 ~]# php /code/mysqli.php
(2)也可以通过浏览器的方式去测试

7.通过LNMP架构部署Wordpress、Wecenter、edusoho、phpmyadmin、ecshop、
7.1例
7.1.1.编写Nginx集成PHP的配置文件 (定义域名以及站点的目录位置)

[root@web01 conf.d]# cat blog.oldxu.com.conf 
server {
    listen 80;
    server_name blog.oldxu.com;
    root /code/wordpress;

    location / {
        index index.php;
    }

    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

7.1.2.根据Nginx配置,初始化环境,然后上传代码

1.准备站点目录
    [root@web01 conf.d]# mkdir /code

    2.下载wordpress代码
    [root@web01 conf.d]# cd /code
    [root@web01 code]# tar xf wordpress-5.2.3-zh_CN.tar.gz

    3.创建数据库名
    [root@web01 code]# mysql -uroot -poldxu.com
    
    MariaDB [(none)]> create database wordpress;
    MariaDB [(none)]> show databases;
    +--------------------+
    | Database           |
    +--------------------+
    | information_schema |
    | mysql              |
    | performance_schema |
    | test               |
    | wordpress          |
    +--------------------+
    5 rows in set (0.01 sec)


    4.统一Nginx  PHP的权限  为  www
    [root@web01 code]# groupadd www -g 666
    [root@web01 code]# useradd -u666 -g666 www
    
    [root@web01 code]# sed -i '/^user/c user www;' /etc/nginx/nginx.conf
    [root@web01 code]# chown -R www.www /code
    [root@web01 code]# systemctl restart nginx
    
    [root@web01 code]# sed -i '/^user/c user = www' /etc/php-fpm.d/www.conf 
    [root@web01 code]#  sed -i '/^group/c group = www' /etc/php-fpm.d/www.conf
    [root@web01 code]# systemctl restart php-fpm

7.2wecenter:

1.编写Nginx的配置文件       虚拟主机
[root@web01 conf.d]# cat zh.oldxu.com.conf
server {
   listen 80;
   server_name zh.oldxu.com;
   root /code/zh;

   client_max_body_size 100m;

   location / {
       index index.php;
   }

   location ~ \.php$ {
       fastcgi_pass 127.0.0.1:9000;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       include fastcgi_params;
   }
}

2.上传代码,变更代码的属主和属组
[root@web01 conf.d]# cd /code
[root@web01 conf.d]# rz WeCenter_3-3-2.zip
[root@web01 conf.d]# mkdir zh
[root@web01 conf.d]# unzip WeCenter_3-3-2.zip -d /code/zh/
[root@web01 code]# chown -R www.www /code

3.登录数据库.创建库名称
[root@web01 code]# mysql -uroot -poldxu.com

MariaDB [(none)]> create database zh;
MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| wordpress          |
| zh                 |
+--------------------+
6 rows in set (0.00 sec)

3.重启Nginx服务
[root@web01 code]# systemctl restart nginx

4.配置host劫持

7.3edusoho视频网站

配置文件
server {
    listen 80;
    server_name www.xxxx.com;
    root /code/edusoho/web;

    # 日志路径
    access_log /var/log/nginx/example.com.access.log;
    error_log /var/log/nginx/example.com.error.log;

    location / {
        index app.php;
        try_files $uri @rewriteapp;
    }

    location @rewriteapp {
        rewrite ^(.*)$ /app.php/$1 last;
    }

    location ~ ^/udisk {
        internal;
        root /code/edusoho/app/data/;
    }

    location ~ ^/(app|app_dev)\.php(/|$) {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param  HTTPS              off;
        fastcgi_param HTTP_X-Sendfile-Type X-Accel-Redirect;
        fastcgi_param HTTP_X-Accel-Mapping /udisk=/code/edusoho/app/data/udisk;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 8 128k;
    }

    # 配置设置图片格式文件
    location ~* \.(jpg|jpeg|gif|png|ico|swf)$ {
        # 过期时间为3年
        expires 3y;

        # 关闭日志记录
        access_log off;

        # 关闭gzip压缩，减少CPU消耗，因为图片的压缩率不高。
        gzip off;
    }

    # 配置css/js文件
    location ~* \.(css|js)$ {
        access_log off;
        expires 3y;
    }

    # 禁止用户上传目录下所有.php文件的访问，提高安全性
    location ~ ^/files/.*\.(php|php5)$ {
        deny all;
    }

    # 以下配置允许运行.php的程序，方便于其他第三方系统的集成。
    location ~ \.php$ {
        # [改] 请根据实际php-fpm运行的方式修改
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param  HTTPS              off;
    }
}
