nginx.conf配置文件(wordpress部分)

`server {

listen 443 ssl;

server_name blog.000000.xyz;

root /wordpress;

index index.html index.htm;

php-fpm7.3运行日志

{"log":"[27-Mar-2020 04:10:15] NOTICE: fpm is running, pid 1n","stream":"stderr","time":"2020-03-27T04:10:15.920559488Z"}

我先安装的是emlog， wordpress还未曾运行成功。

已尝试的解决办法

nginx等待时间超时

PHP FastCGI进程数是否够用，已执行netstat -anpo | grep "php-cgi" | wc -l，输出结果是0

问题以及期望的结果

请问要怎样才能正常访问wordpress程序？

会不会是我的nginx配置文件错了呢？

或者是服务器配置过低跑不起来两个php?
