PKIX路徑構建失敗，但證書是cacerts

Question

我有這個問題也在這里描述。 問題是我創建了一個證書並將其添加到tomcat的密鑰庫中，然后我將其復制到cacerts信任庫。 但是，不知怎的，我仍然得到這個錯誤。

我做了什么：

1）keytool -genkey -alias cas -keyalg RSA -keystore cas.keystore -storepass changeit

2）keytool -exportcert -alias cas -file cas.crt -keystore cas.keystore

步驟2）因為我想把證書放在我的tomcat密鑰庫和cacerts

3）keytool -import -alias cas -file cas.crt -keystore“C：\\ Program Files \\ Java \\ jdk1.8.0_77 \\ jre \\ lib \\ security \\ cacerts”

4）keytool -import -alias cas -file“C：\\ Program Files \\ Java \\ jdk1.8.0_7 \\ jre \\ bin \\ cas.crt”-keystore“D：\\ portal \\ apache-tomcat-8.0.3 \\ conf \\ portal.keystore”

所以現在使用第3步和第4步，我在tomcat密鑰庫和truststore cacerts添加了證書。

現在我可以列出我的信任和密鑰庫

使用此命令..

keytool -list -v -keystore“C：\\ Program Files \\ Java \\ jdk1.8.0_77 \\ jre \\ lib \\ security \\ cacerts”-alias cas

......我明白了：

有了這個：

keytool -list -v -keystore“D：\\ portal \\ apache-tomcat-8.0.30 \\ conf \\ portal.keystore”-alias cas

我明白了：

如果不清楚：證書（cas）是相同的。

所以我的印象是證書現在位於tomcat服務器和truststore cacerts的密鑰庫中。 但不知何故，當我在CAS服務器上輸入我的憑據並重定向時，我仍然會遇到此異常（完整的堆棧跟蹤）：

HTTP Status 500 - javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

這些是我的tomcats server.xml連接器：

<Connector port="8743" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
               maxThreads="150" scheme="https" keystoreFile="${catalina.base}/conf/portal.keystore" keystorePass="changeit" 
               secure="true" connectionTimeout="240000" 
               clientAuth="false" sslProtocol="TLS" allowUnsafeLegacyRenegotiation="true" />

    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8309" protocol="AJP/1.3" redirectPort="8743" />

我的問題的可能原因是什么？ 所有其他線程（如開頭提到的那些線程）指出OP沒有將證書導入cacerts文件，但我做到了。

Answer 1

我的問題非常出乎意料。 我有一個Tomcat，它有一個修改過的setenv.bat ，它有一些指向密鑰庫另一個位置的選項。 我對Tomcat和應用程序服務器的了解並不多，所以我不能早點解決這個問題。

Answer 2

您的Connector元素定義了一個密鑰庫。 這是一個尋找私鑰及其證書的地方。

您的例外涉及信任庫 ，該信任庫是可以找到或找不到可信CA證書的地方。

您需要通過配置或通過javax.net.ssl.trustStore系統屬性以某種方式定義Tomcat使用的信任庫。

Answer 3

您可以導航到tomcat / bin目錄。 修改catalina.sh（或catalina.bat，具體取決於你的操作系統）。

將以下屬性添加到JAVA_OPTS。

JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=$CATALINA_HOME/certificates/truststore.ks -Djavax.net.ssl.trustStorePassword=truststorePassword -server"

我最近不得不自己解決一些truststore / keystore問題。 我發現非常有助於輕松查看/修改信任/密鑰庫的工具是密鑰庫資源管理器 。
