nginx: [emerg] 无法建立 server_names_hash，你应该增加 server_names_hash_bucket_size [英] nginx: [emerg] could not build the server_names_hash, you should increase server_names_hash_bucket_size

问题描述

我正在设置新服务器.我选择的 http-Server 是 NGINX.我想将域 audi-freunde-einbeck.de 添加为虚拟主机.我已经在那里有 2 个其他域并且它工作正常，但是当我尝试添加上述域并启动服务器时，它给我 Job failed.详见系统日志和'systemctl status'.我认为这是因为破折号，所以我尝试了带和不带连字符的其他各种域，但没有运气.同样的错误.什么可能导致这种情况?我也试过重启，我真的很茫然.任何帮助将不胜感激.

I'm in the process of setting up a new server. The http-Server of my choice is NGINX. I want to add the domain audi-freunde-einbeck.de as a virtual host. I already have 2 other domains in there and it works fine, but when I try to add the above mentioned domain and start the server it gives me Job failed. See system journal and 'systemctl status' for details. I thought it was because of the dashes, so I tried just various other domains with and without hyphens, but no luck. Same error. what could be causing this? I also tried rebooting, I am really at a loss here. Any help would be greatly appreciated.

我玩了一会儿发现，当我只放入一个域时，它可以工作.但是当我放入另一个域时，它停止了.这是状态中的输出:

I have played around a bit and found out, that, when I only put one domain in, it works. But when I put another domain in, it stops. Here is the output in status:

推荐答案

这很可能发生，因为域名很长.您可以通过添加

This is most likely happening because of the long domain name. You can fix this by adding

server_names_hash_bucket_size  64;

在 http 块的顶部(可能位于 /etc/nginx/nginx.conf).我从 nginx 文档中引用了出现此错误时该怎么办:在这种情况下，指令值应该增加到 2 的下一个幂.所以在你的情况下它应该变成 64.

at the top of your http block (probably located in /etc/nginx/nginx.conf). I quote from the nginx documentation what to do when this error appears: In this case, the directive value should be increased to the next power of two. So in your case it should become 64.

如果仍然出现同样的错误，请尝试增加到 128 甚至更多.

If you still get the same error, try increasing to 128 and further.
