1.什麼是LNMP架構php

2.LNMP架構是如何工做的css

location / {
    index index.php;
}

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

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

4.如何安裝LNMP架構nginx

安裝phpweb

配置擴展源redis

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

安裝php7.1mongodb

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數據庫

啓動phpcentos

systemctl start php-fpm

安裝mysql

touch /etc/yum.repos.d/mariadb.repo
而後寫入以下內容
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

安裝

yum install mariadb-server mariadb -y

啓動

systemctl start mariadb

5.nginx與php集成的原理

1.編寫能解析的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.編寫PHP代碼,測試訪問效果.

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

5.3host劫持

6.php與mysql集成的原理

6.1啓動數據庫

[root@web01 ~]# systemctl start mariadb

6.2.配置鏈接密碼

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

6.3測試登陸mysql

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

6.4編寫php鏈接數據庫的代碼

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

        // 建立鏈接
        $conn = mysqli_connect($servername, $username, $password);

        // 檢測鏈接
        if (!$conn) {
            die("Connection failed: " . mysqli_connect_error());
        }
        echo "php鏈接MySQL數據庫成功";
    ?>

6.5測試

(1)[root@web01 ~]# php /code/mysqli.php
(2)也能夠經過瀏覽器的方式去測試

7.經過LNMP架構部署Wordpress、Wecenter、edusoho、phpmyadmin、ecshop、
7.1例
7.1.1.編寫Nginx集成PHP的配置文件 (定義域名以及站點的目錄位置)

[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.根據Nginx配置,初始化環境,而後上傳代碼

1.準備站點目錄
    [root@web01 conf.d]# mkdir /code

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

    3.建立數據庫名
    [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.統一Nginx  PHP的權限  爲  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.編寫Nginx的配置文件       虛擬主機
[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.上傳代碼,變動代碼的屬主和屬組
[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.登陸數據庫.建立庫名稱
[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.重啓Nginx服務
[root@web01 code]# systemctl restart nginx

4.配置host劫持

7.3edusoho視頻網站

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

    # 日誌路徑
    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;
    }

    # 配置設置圖片格式文件
    location ~* \.(jpg|jpeg|gif|png|ico|swf)$ {
        # 過時時間爲3年
        expires 3y;

        # 關閉日誌記錄
        access_log off;

        # 關閉gzip壓縮，減小CPU消耗，由於圖片的壓縮率不高。
        gzip off;
    }

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

    # 禁止用戶上傳目錄下全部.php文件的訪問，提升安全性
    location ~ ^/files/.*\.(php|php5)$ {
        deny all;
    }

    # 如下配置容許運行.php的程序，方便於其餘第三方系統的集成。
    location ~ \.php$ {
        # [改] 請根據實際php-fpm運行的方式修改
        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;
    }
}
