nginx多错误指向单页面

默认配置文件地址

/etc/nginx/sites-enabled.d/default.conf

配置50x与404页面

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    #
    # Note: You should disable gzip for SSL traffic.
    # See: https://bugs.debian.org/773332
    #
    # Read up on ssl_ciphers to ensure a secure configuration.
    # See: https://bugs.debian.org/765782
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!
    #
    # include snippets/snakeoil.conf;
    # 默认网站根目录
    root /var/www/html;

    # 默认网站首页支持文件类型
    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;
    
    # 500页面
    error_page 500 502 503 504 http://blog.wangboweb.site;
    # 404页面
    error_page 404 /404.html;
    
    server_name _;

    location = /50x.html {
        root /var/www/html;
    }
    location = /404.html {
        root /var/www/html;
    }
    location / {
        # 从上之下存在优先级
        # 禁止指定ip不可访问,12/200表示12到200的ip段都不可访问
        deny 192.168.12.12/200;
        # 允许访问ip
        allow 192.168.12.32;
        try_files $uri $uri/ =404;
    }

    # pass PHP scripts to FastCGI server
    #
    #location ~ \.php$ {
    #	include snippets/fastcgi-php.conf;
    #
    #	# With php-fpm (or other unix sockets):
    #	fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    #	# With php-cgi (or other tcp sockets):
    #	fastcgi_pass 127.0.0.1:9000;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #	deny all;
    #}
}

本地跳转，在/var/www/html建立名称为404.html的文件

error_page 404 /404.html;

location = /404.html {
    root /var/www/html;
}

外链跳转

error_page 500 502 503 504 http://blog.wangboweb.site;

配置完成后需要重载配置文件

nginx -s reload
