我有一個使用 apache 反向代理運行的 tomcat 應用程式。我正在嘗試限制對主管和主機管理器僅來自本機的上下文。
因此，我從兩個上下文中取消註釋了 context.xml 檔案中的以下行：
<!--
Remove the comment markers from around the Valve below to limit access to
the manager application to clients connecting from localhost
-->
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
但是當我嘗試從本機主機存取這些上下文時，它總是顯示錯誤 403 頁面。
我沒有得到d+的事情在允許屬性所以我也嘗試過允許=“127\.0\.0\.1|::1|0:0:0:0:0:0:0:1”也沒有運氣。
我的 context.xml 配置有問題嗎？
當連接首先通過 apache 的 mod_proxy 時過濾連接時，它的行為是否有所不同（ProxyPass ajp://localhost:8009）？
謝謝
答案1
這裡有兩種不同的機制：限制對上下文的存取（使用RemoteAddrValve）和 中的內建 RBAC server.xml：
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
以下內容已使用進行了測試tomcat-8.0.23：
僅修改庫存配置以限制localhost對上下文的訪問manager，方法是修改apache-tomcat-8.0.23/webapps/manager/META-INF/context.xml文件以刪除閥門上的註釋：
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
如果不進行進一步修改，嘗試存取上下文會失敗並出現 401 HTTP 錯誤：

修改apache-tomcat-8.0.23/conf/tomcat-users.xml文件後加入以下內容：
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>
並嘗試存取上下文，這次使用身份驗證，成功：

現在，如果您嘗試使用不同的介面來執行請求（即否localhost），無論您是否使用身份驗證，您都會遇到 403 HTTP 錯誤：
$ curl --interface wlp6s0 -v -L -utomcat:tomcat localhost:8080/manager/
* Trying ::1...
* Trying 127.0.0.1...
* Local Interface wlp6s0 is ip 192.168.1.187 using address family 2
* SO_BINDTODEVICE wlp6s0 failed with errno 1: Operation not permitted; will do regular bind
* Local port: 0
* Connected to localhost (127.0.0.1) port 8080 (#0)
* Server auth using Basic with user 'tomcat'

這是符合預期的，因為我們只限制存取localhost。
簡而言之，如果收到 403 錯誤回應，請檢查 tomcat 正在偵聽的介面：
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
$ ss -tulpan | grep LISTEN.*8080
以及您用於請求的介面。
tcp LISTEN 0 100 :::8080 :::* users:(("java",pid=32490,fd=48))
答案2
因此，知道我的請求是從伺服器的公共 IP 發送的，我將 context.xml 更改為：
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="xxx\.xxx\.xxx\.xxx|127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
在哪裡xxx.xxx.xxx.xxx是伺服器的公共IP。現在已經開始工作了。
感謝您的協助
