10.Nginx popular architecture LNMP

1. What is the architecture LNMP

LNMP refers to a set of commonly used together to run dynamic Web sites or servers acronym for the name of free software. L refers to Linux, N refers Nginx, M generally refers MySQL, may refer MariaDB, P generally refers to PHP, Perl, or Python can also refer

How 2.LNMP architecture works

location / {
    index index.php;
}

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

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

3.Nginx between PHP, MySQL and how it works

nginx libevent network connection is established through the pool, through the nginx fast_cgi configuration: connecting or unix socket unix (fastcgi_pass ip port) with the tcp 127.0.0.1:9000 manner: ///var/run/unix.sock connected, php and MySQL MySQL by PHP _ extended to achieve tcp connection (the connection may be persistent or non-persistent connection) *

4. How to install LNMP architecture

1. 安装
[root@web01 ~]# vim /etc/yum.repos.d/php.repo 
[webtatic-php]
name = php Repository
baseurl = http://us-east.repo.webtatic.com/yum/el7/x86_64/
gpgcheck = 0

yum install nginx -y
yum remove php-mysql-5.4 php php-fpm php-common
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
yum install mariadb mariadb-server -y

2. 启动nginx php-fpm
    systemctl start nginx
    systemctl start php-fpm

5.Nginx integrated with PHP works.

1.编写能解析PHP的Nginx配置文件
    [root@web01 conf.d]# cat php.cheng.com.conf 
    server {
        listen 80;
        server_name php.cheng.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;
        }
    }
2. 检测语法：
    [root@web01 conf.d]# nginx -t
    
3.重启nginx服务：
    [root@web01 conf.d]# systemctl restart nginx
    
4.编写PHP代码,测试访问效果.
    [root@web01 conf.d]# cat /code/info.php
    <?php
        phpinfo();
    ?>

5.在本地做host劫持

6.PHP and MySQL integration principle.

1.启动数据库
    [root@web01 ~]# systemctl start mariadb
    
2.配置连接密码
    [root@web01 ~]# mysqladmin password 000000
    
3.测试登录mysql
    [root@web01 ~]# mysql -uroot -p000000
    MariaDB [(none)]>
    
4.编写php连接数据库的代码
    [root@web01 conf.d]# cat /code/mysqli.php 
<?php
    $servername = "localhost";
    $username = "root";
    $password = "000000";

    //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";
?>
    
5.可以直接使用php命令测试
    [root@web01 ~]# php /code/mysqli.php

6.也可以通过浏览器去测试

7. Deploy Wordpress, Wecenter, edusoho, phpmyadmin, ecsho by LNMP architecture

1. Wordpress deployment:

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 word.cheng.com.conf 
server {
    listen 80;
    server_name word.cheng.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;

    }   

}


2.检测语法：
[root@web01 conf.d]# nginx -t

3.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.上传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 -p000000
    
    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]# chown -R www.www /code
    
5.修改配置及重启nginx php
    [root@web01 code]# sed -i '/^user/c user www;' /etc/nginx/nginx.conf
    [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
    
6.域名解析

2.Wecenter deployment:

1.编写Nginx的配置文件

    server_name zh.cheng.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]# mkdir /code/zh
[root@web01 conf.d/zh]# rz WeCenter_3-3-2.zip
[root@web01 conf.d/zh]# unzip WeCenter_3-3-2.zip  
[root@web01 code]# chown -R www.www /code

3.登录数据库.创建库名称
[root@web01 code]# mysql -uroot -p000000

MariaDB [(none)]> create database zh;
MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| wordpress          |
| zh                 |
+--------------------+
