一键lnmp1.4配置的php没有7.3版本，此时想要再多一个php7.3的版本，需要用lnmp1.6操作。
1.查看自己的php
[root@localhost ~]# whereis php
php: /usr/bin/php /usr/local/php
[root@localhost ~]# php -v
PHP 5.6.31 (cli) (built: Jan 28 2019 17:29:03)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
with Zend Guard Loader v3.3, Copyright (c) 1998-2014, by Zend Technologies
2.下载lnmp1.6
[root@localhost ~]# wget http://soft.vpser.net/lnmp/lnmp1.6-full.tar.gz
3.解压并进入lnmp1.6
[root@localhost ~]# tar zxf lnmp1.6-full.tar.gz && cd lnmp1.6-full
4.安装自己想要的php版本
[root@localhost ~]# ./install.sh mphp
5.再次查看php
[root@localhost ~]# whereis php
php: /usr/bin/php /usr/local/php7.3 /usr/local/php
6.查看nginx配置多了一个php7.3文件,php安装的目录多了一个7.3的
[root@localhost ~]# vim /usr/local/nginx/conf/
enable-php7.3.conf enable-ssl-example.conf fastcgi_params koi-win mime.types.default pathinfo.conf scgi_params.default vhost/
enable-php.conf fastcgi.conf fastcgi_params.default magento2-example.conf nginx.conf rewrite/ uwsgi_params win-utf
enable-php-pathinfo.conf fastcgi.conf.default koi-utf
[root@localhost ]# cd /usr/local/
aegis/ bin/ etc/ games/ kafka/ lib64/ man/ my_zookeeper/ php/ sbin/ src/
autoconf-2.13/ erlang/ freetype/ include/ lib/ libexec/ mysql/ nginx/ php7.3/ share/ zend/
7.创建nginx 的vhost配置，设置为enable-php.conf为7.3;
{
listen 80;
#listen [::]:80 default_server ipv6only=on;
server_name jiqing.php7proj.com;
index index.html index.htm index.php;
root /home/wwwroot/default/php7proj;
#error_page 404 /404.html;
include enable-php7.3.conf;
location /nginx_status
{
stub_status on;
access_log off;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
......
