宝塔面板LINUX环境下如何实现多个二级域名301重定向跳转主域名？

一、 选择主域名 -> 设置 -> 配置文件，如下图所示。

二、修改“配件文件”代码，这里以主域名“abc.com”为例，要给二级域名“a.xxx.com”和“b.xxx.com”做301分别跳转到“网址1.com”和“网址2.com”，即 a.xxx.com 跳到 网址1.com b.xxx.com 跳到 网址2.com。

配置文件代码如下：

server
{
    listen 80;
    server_name xxx.com www.xxx.com;
    index index.html index.php index.htm default.php default.htm default.html;
    root /www/wwwroot/xxx;

    #SSL-START SSL相关配置，请勿删除或修改下一行带注释的404规则
    #error_page 404/404.html;
    #301-START
        if ($host ~ '^xxx.com'){
            return 301 http://www.xxx.com$request_uri;
        }
    #301-END
    #SSL-END

    #ERROR-PAGE-START  错误页配置，可以注释、删除或修改
    error_page 404 /404.html;
    error_page 502 /502.html;
    #ERROR-PAGE-END

    #PHP-INFO-START  PHP引用配置，可以注释或修改
    include enable-php-54.conf;
    #PHP-INFO-END

    #REWRITE-START URL重写规则引用,修改后将导致面板设置的伪静态规则失效
    include /www/server/panel/vhost/rewrite/xxx.com.conf;
    #REWRITE-END

    #禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }

    #一键申请SSL证书验证目录相关设置
    location ~ \.well-known{
        allow all;
    }

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

    location ~ .*\.(js|css)?$
    {
        expires      12h;
        error_log off;
        access_log off; 
    }
    access_log  /www/wwwlogs/xxx.com.log;
    error_log  /www/wwwlogs/xxx.com.error.log;
}


#BINDING-a.xxx.com-START
server
{
    listen 80;
    server_name a.xxx.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/xxx/a;

    #301-START
        
    #301-END

    include enable-php-54.conf;
    include /www/server/panel/vhost/rewrite/xxx.com.conf;
    #禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }

    #一键申请SSL证书验证目录相关设置
    location ~ \.well-known{
        allow all;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        error_log off;
        access_log off; 
    }
    location ~ .*\.(js|css)?$
    {
        expires      12h;
        error_log off;
        access_log off; 
    }
    access_log /www/wwwlogs/xxx.com.log;
    error_log  /www/wwwlogs/xxx.com.error.log;
}
#BINDING-a.xxx.com-END

#BINDING-b.xxx.com-START
server
{
    listen 80;
    server_name b.xxx.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/xxx/b;

    #301-START
        
    #301-END

    include enable-php-54.conf;
    include /www/server/panel/vhost/rewrite/xxx.com.conf;
    #禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }

    #一键申请SSL证书验证目录相关设置
    location ~ \.well-known{
        allow all;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        error_log off;
        access_log off; 
    }
    location ~ .*\.(js|css)?$
    {
        expires      12h;
        error_log off;
        access_log off; 
    }
    access_log /www/wwwlogs/xxx.com.log;
    error_log  /www/wwwlogs/xxx.com.error.log;
}
#BINDING-b.xxx.com-END

找到 #301-START  的配置项操作保存后，清理下本地浏览器缓存后，就尝试下输入原域名吧，看看有没有成功实现301重定向。
