虚拟机上centos系统安装LNMP，windows端访问其PHP文件

mkdir -p /lnmp/php7
mkdir /lnmp/nginx

yum install gcc gcc-c++ automake pcre pcre-devel zlip zlib-devel openssl openssl-devel libxml2-devel libpng-devel curl-devel numactl

cd /lnmp
yum -y install wget		#安装wget，开始的系统是没有安装这个工具的

wget http://nginx.org/download/nginx-1.16.0.tar.gz		#下载nginx
tar xvf nginx-1.16.0.tar.gz		#解压
cd nginx-1.16.0

./configure --prefix=/lnmp/nginx --with-http_ssl_module		#安装到/lnmp/nginx
make && make install		#编译&安装

cp /lnmp/nginx/sbin/nginx /usr/bin/ # 先确定被拷贝的目录是否存在

nginx 	#开启
nginx -s stop	#关闭
nginx -s reload		#平滑重启

/lnmp/nginx/sbin/nginx -c /lnmp/nginx/conf/nginx.conf

#nginx配置位置：/lnmp/nginx/conf/nginx.conf
#站点目录位置：/lnmp/nginx/html

#搭好后，本地无法访问
#关闭防火墙
sudo systemctl stop firewalld
#允许访问80端口
/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT

#此时就可以访问了

cd /lnmp

wget https://www.php.net/distributions/php-7.3.5.tar.gz
tar xvf php-7.3.5.tar.gz
cd php-7.3.5

./configure --prefix=/lnmp/php7 --enable-fpm --with-mysqli --with-curl --with-pdo_mysql --with-pdo_sqlite --enable-mysqlnd --enable-mbstring --with-gd

#移到lnmp目录，重命名mysql

cd /lnmp/mysql
mkdir data　　#用于存放数据

#创建mysql用户组和mysql用户
groupadd mysql

#修改mysql目录权限
chown -R mysql.mysql /lnmp/mysql/

#初始化
