Ubuntu 18.04 手动配置基于nginx的多个PHP版本
服务器上有时会运行多个站点，可能每个站点对PHP版本要求不同，所以需要在一台服务器上配置多个PHP的版本，这里我们讲一下如何配置多套PHP版本。
这里以安装PHP的最新版本7.4为例，安装PHP过程一样，安装时候可以通过apt-cache search php7.4 查看安装源是否有这个版本，我们运行脚本得到如下结果：

可以看到返回结果里有php7.4的安装源，接下来运行下面脚本安装PHP7.4
|
1 |
apt install php7.4 php7.4-fpm php7.4-gd php7.4-mysql php7.4-curl php7.4-json php7.4-xml php7.4-xmlrpc php7.4-intl php7.4-zip php7.4-mbstring -y |
等安装完成后，配置nginx，nginx的配置文件修改如下：
|
1 2 3 4 5 6 7 8 9 |
location ~ \.php$ { include snippets/fastcgi-php.conf; # # # With php7.0-cgi alone: # fastcgi_pass 127.0.0.1:9000; # # With php7.0-fpm: fastcgi_pass unix:/run/php/php7.4-fpm.sock; } |
修改完保存后，重新加载nginx配置，命令如下：
|
1 |
/etc/init.d/nginx reload |
运行脚本，返回结果如下：
|
1 |
[ ok ] Reloading nginx configuration (via systemctl): nginx.service. |
说明新站点已经使用PHP7.4，可以使用phpinfo()查看当前站点的相关信息。
安装其他版本PHP，操作同上。
