注意

1、php的www.conf配置文件中的listen的监听方式是什么
1）listen 127.0.0.1:9000; 那么nginx中的配置为fastcgi_pass 127.0.0.1:9000;
2) listen = /var/opt/remi/php80/run/php-fpm/www.sock; 那么nginx中的配置为fastcgi_pass unix:///var/opt/remi/php80/run/php-fpm/www.sock;

2、注意准备的nginx配置文件，在哪个目录。 playbook中nginx的配置文件在/root目录中

3、注意下载的wordpress项目包的名字及所放到目录是哪个，还有就是梳理清晰nginx到网站发布目录是哪里。
