wordpress安装时网页无法打开-调试办法(还没整理完)

我用的是ubuntu20.04,相关的php依赖包是7.4

我安装的php依赖包如下:
root@Desktop:/home/appleyuchi# dpkg --list|grep php

依赖包名称	版本号	支持的硬件架构	依赖包说明
php-common	2:75	all	Common files for PHP packages
php-fpm	2:7.4+75	all	server-side, HTML-embedded scripting language (FPM-CGI binary) (default)
php-gd	2:7.4+75	all	GD module for PHP [default]
php-mysql	2:7.4+75	all	MySQL module for PHP [default]
php7.4-cli	7.4.3-4ubuntu2.3	amd64	command-line interpreter for the PHP scripting language
php7.4-common	7.4.3-4ubuntu2.3	amd64	documentation, examples and common module for PHP
php7.4-fpm	7.4.3-4ubuntu2.3	amd64	server-side, HTML-embedded scripting language (FPM-CGI binary)
php7.4-gd	7.4.3-4ubuntu2.3	amd64	GD module for PHP
php7.4-json	7.4.3-4ubuntu2.3	amd64	JSON module for PHP
php7.4-mysql	7.4.3-4ubuntu2.3	amd64	MySQL module for PHP
php7.4-opcache	7.4.3-4ubuntu2.3	amd64	Zend OpCache module for PHP
php7.4-readline	7.4.3-4ubuntu2.3	amd64	readline module for PHP

所以不同的ubuntu有不同的php依赖包版本,不要照抄我的,根据自己的版本号来做相应的修改

浏览器访问	网页报错	/etc/nginx/error.log报错	解决方案
http://localhost:80/wp-admin/install.php	502	connect() to unix:/var/run/php/php7.1-fpm.sock failed (2: No such file or directory)	nginx.conf中/var/run/php/php7.1-fpm.sock;/var/run/php/php7.4-fpm.sock然后nginx -s reload
登陆之后	404	[error] 500558#500558: *127 “/usr/share/nginx/html/wp-admin/index.php” is not found (2: No such file or directory), client: 127.0.0.1, server: localhost, request: “GET /wp-admin/ HTTP/1.1”, host: “localhost”, referrer: “http://localhost/wp-login.php”

是否需要编译版本的nginx
另外,网上有博主说需要自己编译nginx,
这个可用可不用,我们用自带的就好了.
