1.LNMP工作原理

2.LNMP安装

nginx、mysql、php关闭防火墙

（1）安装 Nginx 服务

安装 Nginx 服务20.0.0.100

cd /opt/
rz -E  #上传
tar xf nginx-1.26.0.tar.gz
cd nginx-1.26.0/
##安装依赖包
yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make  
##创建运行用户、组
useradd -M -s /sbin/nologin nginx   ##创建运行用户
cat /etc/passwd | grep nginx：

 ##编译安装
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module  --with-http_ssl_module

make -j 2 && make install
##路径优化

（3）安装配置 PHP解析环境

安装php服务20.0.0.130
cd /opt/
rz -E  #上传
tar xf php-7.1.10.tar.bz2
ls
cd php-7.1.10/

#安装环境依赖包

libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel pcre-devel

#配置软件模块
./configure \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \

##编译安装
make -j 2 && make install
##路径优化
cd /usr/local/php/
ls
ls bin/
ls sbin/
ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/

php --ini
##修改主配置文件
cd /opt/php-7.1.10/
ls
cp php.ini-production /usr/local/php/lib/php.ini
cd /usr/local/php/lib/
ls
vim php.ini
--939行--取消注释，修改
date.timezone = Asia/Shanghai

#修改进程服务配置文件
cd /usr/local/php/
cd etc/
pwd ----- /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
ls
vim php-fpm.conf
17取消pid = run/php-fpm.pid    ##启动php-fpm

#修改扩展配置文件
cd php-fpm.d/
ls
cp www.conf.default www.conf    ##调整扩展配置文件：

vim www.conf
#修改用户名和组名23/24行
user = nginx  
group = nginx  
#将监听地址改为本机地址36行
listen = 20.0.0.130:9000
listen.allowed_clients = 20.0.0.100  ##允许访问nginx62行

#创建用户
useradd -M -s /sbin/nologin nginx
cat /etc/passwd | grep nginx:   安装配置 PHP解析环境20.0.0.130
#启动php-fpm
cd /opt/php-7.1.10/
ls
cd sapi/
ls
cd fpm/
ls             
cp php-fpm.service /usr/lib/systemd/system
systemctl daemon-reload
systemctl start php-fpm.service
systemctl enable php-fpm.service
netstat -lntp | grep php

systemctl restart php-fpm.service   ##重新启动服务

启动php-fpm

（4）验证

nginx
##修改 nginx.conf 配置文件
cd /usr/local/nginx/conf/

vim nginx.conf
     worker_processes auto;
     worker_rlimit_nofile 65535;
   
   events {
     use epoll;  ##添加
     worker_connections 65535;
    
    server_name www.xlb666.com;
    charset utf-8;

       
       location / {      
            root   /var/www/html; 
          index  index.php index.html index.htm index.php;
 

  location ~ \.php$ {
  root /var/www/html;   
  fastcgi_pass 20.0.0.130:9000;  ##php地址
  fastcgi_index index.php;
  fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;	
  include fastcgi_params;

}

nginx -t
##验证PHP 测试页

##为虚拟主机准备网页文档
mkdir -p /var/www/html
 ##动态页面  
cd /var/www/html/               
vim test.php
<?php
phpinfo();
?>

##静态页面
cd /usr/local/nginx/html/  

vim xlb.html
<h1>this is xlb static web</h1>
<img src="xlb.jpg"/>

echo "20.0.0.100 www.xlb666.com" >> /etc/hosts

http://www.xlb666.com/xlb.html
http://20.0.0.100/xlb.html

yum install -y rpcbind nfs-utils

vim /etc/exports
/var/www/html 20.0.0.0/24(rw,sync,no_root_squash)

systemctl enable --now rpcbind 
systemctl enable --now nfs
showmount -e

因为我们静态页面是由Nginx直接处理和响应的，而动态页面是Nginx通过fastcgi接口转发给php-fpm进程接受，然后再由php解析器处理解释动态页面后响应返回给Nginx，Nginx再返回给客户端的，所以我们要在将动态页面位置也放入到php服务器中

php
showmount -e 20.0.0.100

vim /etc/fstab
20.0.0.100:/var/www/html  /var/www/html   nfs  defaults 0 0

mkdir -p /var/www/html
mount -a
df -h
ls /var/www/html/

http://www.xlb666.com/test.php
systemctl restart nginx.service   ##重启nginx服务
