問題描述

在一臺服務器設置了Nginx多站點，但是訪問這些站點的域名均無法訪問，錯誤如下圖：

通過ip會跳轉到其中一個站點，具體表現為：

全部配置開啟的情況下所有域名無法訪問，ip訪問顯示的是siteD去除siteD后跳轉siteB,去除siteB后404，去除siteB后跳轉siteA，去除siteA后跳轉siteC

檢查了半天還是不知道是啥問題，請各位大神幫忙排查下/w

以下為具體配置文件：

問題解答

此問題已在v2ex獲得解答，由@Showfom 解答，原因為域名沒有備案，被機房屏蔽了

貌似缺省值的default，不用通配符比較好

server { listen 80 default; return 404 ’no site found’;}回答3：

檢查域名是否被有效的解析到服務器, 若未被正確解析, 在域名運營商處設置正確解析.

檢查服務器防火墻設置, 時候開啟 80 端口訪問限制, 另也檢查服務器運營商是否也有設置防火墻設定.

在配置好 nginx 后, 可在服務器進行測試是否可用.

curl siteA.domain.com

若域名處于未解析狀態

echo ’127.0.0.1 siteA.domain.com’ >> /etc/hostssystemctl restart nginxcurl siteA.domain.com

服務器若不能正常訪問, 則問題出現在 nginx 配置上.服務器若能訪問, 而本地不行, 則問題就發生在域名解析或防火墻.

從我所知不多的 nginx 配置知識上來看, 沒有太大毛病.
