将域添加到 NGINX 配置，需要增加 server_names_hash_bucket_size，但 HTTP 指令失败

Question

我需要将现有站点移动到另一台服务器。我有问题。这是原始（工作）nginx 配置：

# Define a default server, to catch requests directly to the servers IP or other non-valid sources/domains/etc.
server {
    listen                          80 default_server;
    return                          444;
}


# main.domain1 (everything defaults to this subdomain, it's a domain hack)
server {
    listen                          80;
    listen                          443 ssl;
    server_name                     main.domain1.com;
    ssl_certificate                 /etc/nginx/ssl/main.domain1.com.bundle.crt;
    ssl_certificate_key             /etc/nginx/ssl/main.domain1.com.key;
    root                            /www/main.domain1.com;
    index                           index.php index.html index.htm;

    location /blog {
        try_files                   $uri /?p=blog&$args;
    }

    location /contact {
        try_files                   $uri /?p=contact&$args;
    }

    location /pics {
        autoindex                   on;
    }

    location ~ /\. {
        return                      444;
    }

    location ~ \.php$ {
        #try_files                  $uri =404;

        #fastcgi_pass               unix:/var/run/php5-fpm.sock;
        fastcgi_pass                127.0.0.1:9000;
        fastcgi_index               index.php;
        include                     fastcgi_params;
    }
}
# no sub-domain or one of the other TLD's should direct to main.domain1.com
server {
    listen                          80;
    listen                          443 ssl;
    server_name                     domain1.com .domain1.net .domain1.org;
    return                          301 $scheme://main.domain1.com$request_uri;
}


# domain2.com (note: this is just a testing domain for main.domain1 without the subdomain)
server {
    listen                          80;
    server_name                     domain2.com;
    root                            /www/domain2.com;

        try_files                   $uri /?p=contact&$args;
    }

    location /pics {
        autoindex                   on;
    }

    location ~ /\. {
        return                      444;
    }

    location ~ \.php$ {
        #try_files                  $uri =404;
        fastcgi_split_path_info     ^(.+?\.php)(/.+)$;
        #fastcgi_pass               unix:/var/run/php5-fpm.sock;
        fastcgi_pass                127.0.0.1:9000;
        include                     fastcgi_params;
        auth_basic                  "Restricted";
        auth_basic_user_file        /www/domain2.com/.htpasswd;
    }
}


# domain3.com
server {
    listen                          80;
    server_name                     domain3.com;
    root                            /www/domain3.com;
    index                           index.php index.html index.htm;

    location ~ /\. {
        return                      444;
    }

    location ~ \.php$ {
        #try_files                  $uri =404;
        fastcgi_split_path_info     ^(.+\.php)(/.+)$;

# catches https traffic to these other domains and sends them to non-https
# user will see ssl warning from a.ntivir.us before being redirected however
# this is not ideal, but about all we can do I think
server {
    listen                          443 ssl;
    server_name                     domain2.com domain3.com;
    return                          301 http://$host;
}

我的第一次尝试是简单地复制 domain3 的服务器块，并用 domain4.com 替换它。尝试重新启动/重新加载 nginx 时出现此错误：

nginx: [emerg] 无法构建 server_names_hash，你应该增加 server_names_hash_bucket_size: 32

所以，我将所有服务器块包装在 http {} 指令中，并在 http 级别定义 server_names_hash_bucket_size 64 并且 nginx 仍然无法加载，说这里不允许使用 http 指令。从 nginx 文档中，它说它需要成为所有服务器块的父级，所以我不明白我需要在哪里增加大小。

Answer 1

我想您已经在 /etc/nginx/nginx.conf （用于 debian/ubuntu）中有 http {} 部分，不需要创建另一个（包装器）。

尝试在那里放置散列命令（server_names_hash_max_size 或 server_names_hash_bucket_size）。
