Tomcat在端口8080上運行，但無法使用IP地址遠程訪問？

Question

我已經在我的服務器上新安裝了apache-tomcat-7.0.62。 當我啟動tomcat時，它開始時沒有錯誤，但是當我想使用瀏覽器訪問它時，它說頁面不可用。 我使用以下命令檢查tomcat是否正常運行： -

     netstat -ntlp | grep LISTEN

以下是輸出： -

tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN -
tcp 0 0 127.0.0.1:8005 0.0.0.0:* LISTEN 19430 / java
tcp 0 0 0.0.0.0:8009 0.0.0.0:* LISTEN 19430 / java
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN -
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 19430 / java
tcp6 0 0 ::: 22 ::: * LISTEN -
tcp6 0 0 ::: 8000 ::: * LISTEN -
tcp6 0 0 ::: 80 ::: * LISTEN -

以下是catalina.out的內容

Answer 1

請檢查是否可以從外面訪問8080端口。 端口可能被阻止。 檢查防火牆設置並打開http請求的端口。

Answer 2

您必須為路由器設置NAT才能從Internet連接。
如果從lan連接，則無需執行此操作。
我查了一下，你的港口正在關閉。
使用此工具檢查http://www.yougetsignal.com/tools/open-ports/
或者http://www.canyouseeme.org/

Answer 3

1. 禁用firewalld：

    # systemctl stop firewalld # systemctl disable firewalld 

2. 將localhost替換為可在server.xml外部公開的有效IP
