LNMP简介
LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。
Linux是一类Unix计算机操作系统的统称，是目前最流行的免费操作系统。代表版本有：debian、centos、ubuntu、fedora、gentoo等。
Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。
Mysql是一个小型关系型数据库管理系统。
PHP是一种在服务器端执行的嵌入HTML文档的脚本语言。
这四种软件均为免费、高效、扩展性强的网站服务系统。

环境准备
关闭防火墙以SELINUX
[root@yanyinglai3 ~]# systemctl stop firewalld
[root@yanyinglai3 ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

安装后配置
[root@yanyinglai3 ~]# echo 'export PATH=/usr/local/php7/bin:$PATH' > /etc/profile.d/php7.sh
[root@yanyinglai3 ~]# source /etc/profile.d/php7.sh

配置php-fpm
[root@yanyinglai3 php-7.2.8]# cp php.ini-production /etc/php.ini
[root@yanyinglai3 php-7.2.8]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@yanyinglai3 php-7.2.8]# chmod +x /etc/rc.d/init.d/php-fpm
[root@yanyinglai3 php-7.2.8]# cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
[root@yanyinglai3 php-7.2.8]# cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
编辑php-fpm的配置文件（/usr/local/php7/etc/php-fpm.conf）
配置fpm的相关选项为你所需要的值:
[root@yanyinglai3 ~]# vi /usr/local/php7/etc/php-fpm.conf
pm.max_children = 50 //最多同时50个进程提供50个并发服务
pm.start_servers = 5 //启动时启动5个进程
pm.min_spare_servers = 2 //最小空闲进程数
pm.max_spare_servers = 8 //最大空闲进程数
[root@yanyinglai3 ~]# tail /usr/local/php7/etc/php-fpm.conf
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
; - the global prefix if it's been set (-p argument)
; - /usr/local/php7 otherwise
include=/usr/local/php7/etc/php-fpm.d/*.conf
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8
启动php-fpm
[root@yanyinglai3 ~]# service php-fpm start
Starting php-fpm done
[root@yanyinglai3 ~]# ss -antl

root 69354 1705 0 21:03 pts/0 00:00:00 grep --color=auto php
4.配置nginx
编辑nginx配置文件/usr/local/nginx/conf/nginx.conf，主要修改nginx的server {}配置块中的内容，修改location块，追加index.php让nginx服务器默认支持index.php为首页：
[root@yanyinglai3 ~]# vim /usr/local/nginx/conf/nginx.conf
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm//在此处添加 index.php;
}
然后配置.php请求被传送到后端的php-fpm模块，默认情况下php配置块是被注释的，此时去掉注释并修改为以下内容：
[root@yanyinglai3 ~]# vim /usr/local/nginx/conf/nginx.conf
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
//搜索找到\.php$ 在{}里面添加以上内容
这里面很多都是默认的，root是配置php程序放置的根目录，主要修改的就是fastcgi_param中的/scripts为$document_root
测试PHP程序
在nginx下的html目录下创建test.php文件并打印配置php
[root@yanyinglai3 ~]# cd /usr/local/nginx/
[root@yanyinglai3 nginx]# ls
client_body_temp fastcgi_temp logs sbin uwsgi_temp
conf html proxy_temp scgi_temp
[root@yanyinglai3 nginx]# cd html/
[root@yanyinglai3 html]# touch test.php
[root@yanyinglai3 html]# cat > test.php << EOF
> phpinfo();
> ?>
> EOF
验证
打开浏览器输入 192.168.47.12/test.php进行访问，看到输出页面，说明nginx和php都配置成功了
