如何限制對反向代理 tomcat 上下文的上下文的訪問?
我有一個使用 apache 反向代理執行的 tomcat 應用程序。我試圖限制僅從本地主機訪問管理器和主機管理器上下文。
因此,我從兩個上下文中取消了對 context.xml 文件的以下行的註釋:
<!-- 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 localhost 訪問這些上下文時,它總是向我顯示錯誤 403 頁面。
我沒有在允許屬性中得到*d+的東西,所以我也嘗試了allow=“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?
當它們首先通過 apache 的 mod_proxy ( ProxyPass ajp://localhost:8009 ) 過濾連接時,它的行為是否有所不同?
謝謝
這裡有兩種不同的機制:限制對上下文的訪問(使用 完成
RemoteAddrValve
)和內置的 RBACserver.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" />
以下已使用 進行了測試
tomcat-8.0.23
:僅通過修改文件以刪除閥門上的註釋來修改庫存配置以限制
localhost
對manager
上下文的訪問:apache-tomcat-8.0.23/webapps/manager/META-INF/context.xml
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
如果沒有進一步的修改,訪問上下文的嘗試會失敗並出現 401 HTTP 錯誤:

修改
apache-tomcat-8.0.23/conf/tomcat-users.xml
文件後添加以下內容:<role rolename="manager-gui"/> <user username="tomcat" password="tomcat" roles="manager-gui"/>
並嘗試訪問上下文,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 not
localhost
),無論您是否使用身份驗證,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' > GET /manager/ HTTP/1.1 > Authorization: Basic dG9tY2F0OnRvbWNhdA== > User-Agent: curl/7.40.0 > Host: localhost:8080 > Accept: */* > < HTTP/1.1 403 Forbidden < Server: Apache-Coyote/1.1 < Set-Cookie: JSESSIONID=2F3ADE627300D4D264478927D1F0BBFC; Path=/manager/; HttpOnly < Content-Type: text/html;charset=ISO-8859-1 < Content-Length: 3196 < Date: Sun, 14 Jun 2015 09:06:52 GMT <
這是預期的,因為我們只限制訪問
localhost
。簡而言之,如果收到 403 錯誤響應,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))
