Typecho后台404错误修复

是NGINX的伪静态的配置问题
编辑NGINX配置文件
/usr/local/nginx/conf/
合理配置如下：

server
    {
        listen 80 default_server reuseport;
        #listen [::]:80 default_server ipv6only=on;
        server_name _;
        index index.html index.htm index.php;
        root  /home/wwwroot/default;

        #error_page   404   /404.html;

        # Deny access to PHP files in specific directory
        #location ~ /(wp-content|uploads|wp-includes|images)/.*\.php$ { deny all; }

        # include enable-php.conf;
    include enable-php-pathinfo.conf;
    include rewrite/other.conf;

        location /nginx_status
        {
            stub_status on;
            access_log   off;
        }

        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }

        location ~ .*\.(js|css)?$
        {
            expires      12h;
        }

        location ~ /.well-known {
            allow all;
        }

        location ~ /\.
        {
            deny all;
        }

        access_log  /home/wwwlogs/access.log;
    }

修复附件上传失败

vim /var/Typecho/Common.php

public static function isAppEngine()
    {
        return !empty($_SERVER['HTTP_APPNAME'])                     // SAE
            || !!getenv('HTTP_BAE_ENV_APPID')                       // BAE
            || !!getenv('HTTP_BAE_LOGID')                           // BAE 3.0
            || (ini_get('acl.app_id') && class_exists('Alibaba'))   // ACE
            || (isset($_SERVER['SERVER_SOFTWARE']) && strpos($_SERVER['SERVER_SOFTWARE'],'Google App Engine') !== false) // GAE
            ;
    }

修改为

public static function isAppEngine()
{
    return false;
}

同时把typecho里的usr文件权限修改为777，就可以了。
sudo chmod -R 777 usr
