1、lnmp架构概述
lnmp是一套技术组合，L =Linux 、N =nginx 、M~ = MySQL 、P~ = PHP
2、nginx 与 fastcgi工作流程
用户通过http协议发送请求，请求会先抵达lnmp架构中的nginx
nginx会根据用户的请求进行判断有没有location，有，则判断是静态页面还是动态页面
nginx会根据用户的请求进行判断有没有location，有，则判断是静态页面还是动态页面
如果是静态，nginx直接返回，如果是动态，nginx会将请求发给fastcgi协议
然后fastcgi会将请求交给php-fpm管理进程，php-fpm管理进程会调用工作进程warrap
然后warrap工作进程会调用PHP
序进行解析，解析代码PHP直接返回，查询数据库，PHP连接数据库的用户和密码进行查询
最终数据由 mysql数据库--->php程序---->warrap工作进程---->php-fpm管理进程----->fastcgi协议---->nginx--->user用户
操作
1、架构环境部署
#1、卸载旧版本
[root@web01 ~]# yum remove php-mysql-5.4 php php-fpm php-common -y
#2、安装扩展源
[root@web01 ~]# yum localinstall -y http://mirror.webtatic.com/yum/el7/webtatic-release.rpm
#3、安装新版本
[root@web01 ~]# 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
#4、启动
[root@web01 ~]# systemctl restart php-fpm
[root@web01 ~]# systemctl enable php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
#5、安装数据库
[root@web01 ~]# yum install mariadb-server mariadb
#6、启动数据库
[root@web01 ~]# systemctl restart mariadb
[root@web01 ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
2、、nginx与PHP集成的原理
#1、编写能解析PHP的nginx配置文件
[root@web01 ~]# cd /etc/nginx/conf.d/
[root@web01 conf.d]# vim php.yangyang.com.conf
[root@web01 conf.d]# cat php.yangyang.com.conf
server{
listen 80;
server_name php.yangyang.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、编写PHP代码，测试访问效果
[root@web01 conf.d]# cat /code/info.php
<?php
phpinfo();
?>
#3、检测、重启
[root@web01 conf.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntaxis ok
nginx: configuration file /etc/nginx/nginx.conf test is sucessful
[root@web01 conf.d]# systemctl restart nginx
#3、host劫持
10.0.0.7 php.yangyang.com

3、PHP与MySQL集成的原理。
#1.启动数据库
[root@web01 ~]# systemctl start mariadb
#2.配置连接密码
[root@web01 ~]# mysqladmin password yangyang.com
#3.测试登录mysql
[root@web01 ~]# mysql -uroot -pyangyang.com
MariaDB [(none)]>
#4.编写php连接数据库的代码
[root@web01 ~]# cat code/mysqli.php
<?php
$servername = "localhost";
$username = "root";
$password = "yangyang.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";
?>
#5、测试PHP命令
[root@web01 ~]# php /code/mysqli.php
#6、通过浏览器访问（下面的图）

4、通过LNMP架构部署Wordpress、edusoho、phpmyadmin、ecshop、
#1、配置php的文件
[root@web01 ~]# cat /etc/yum.repos.d/php.repo
[webtatic-php]
name = php Repository
baseurl = http://us-east.repo.webtatic.com/yum/el7/x86_64/
gpgcheck = 0
#2、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.yangyang.com.conf
server {
listen 80;
server_name blog.yangyang.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;
}
}
#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.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 -pyangyang.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

5、通过LNMP架构部署 Wecenter
#1、编写nginx的配置文件
[root@web01 ~ ]# cd /etc/nginx/conf.d/
[root@web01 conf.d]# cat zh.yangyang.com.conf
server{
listen 80;
server_name zh.yangyang.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 code]# rz WeCenter_3-3-2.zip
[root@web01 code]# ll
WeCenter_3-3-2.zip
[root@web01 code]# unzip WeCenter_3-3-2.zip
[root@web01 code]# mkdir zh
[root@web01 code]# chown -R www.www /code
#3、登录数据库，创建库名称
[root@web01 conf.d]# mysql -uroot -pyangyang.com
