PKIX路径构建失败，但证书是cacerts

我遇到的问题也是here。 问题是我创建了一个证书并将其添加到tomcat的密钥库中，然后我将其复制到cacerts信任库。但是，我仍然得到这个错误。

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

步骤2）因为我想将证书放在我的tomcat密钥库和cacerts

中
  

3）keytool -import -alias cas -file cas.crt -keystore“C：\ Program   文件\爪哇\ jdk1.8.0_77 \ JRE \ lib \ security中\ cacerts中“

     

4）keytool -import -alias cas -file“C：\ Program   Files \ Java \ jdk1.8.0_7 \ jre \ bin \ cas.crt“-keystore   “d：\门户\ Apache的Tomcat的8.0.3 \ CONF \ portal.keystore”

现在，在第3步和第4步，我在tomcat密钥库和信任库cacerts中添加了证书。

现在我可以列出我的信任和密钥库

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：

用这个：

  

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：证书（cas）是相同的。

所以我的印象是证书现在位于tomcat服务器和信任库cacerts的密钥库中。但不知何故，当我在CAS服务器上输入我的凭据并重定向时，我仍然会遇到此异常（完全堆栈跟踪）：

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

这些是我的tomcats server.xml中的连接器：

<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" />

问题的可能原因是什么？所有其他线程（如开头提到的那些线程）指出OP没有将证书导入cacerts文件，但我做到了。

3 个答案:

答案 0 :(得分：3)

我的问题非常出乎意料。我有一个Tomcat，它有一个修改过的setenv.bat，它有一些指向密钥库另一个位置的选项。我对Tomcat和应用程序服务器的了解并不多，所以我不能早点解决这个问题。

答案 1 :(得分：2)

您的Connector元素定义了一个密钥库。这是一个可以查找私钥及其证书的地方。

您的例外涉及 truststore ，这是一个可以找到或找不到可信CA证书的地方。

您需要通过配置或通过javax.net.ssl.trustStore系统属性以某种方式定义Tomcat使用的信任库。

答案 2 :(得分：2)

您可以导航到tomcat / bin目录。修改catalina.sh（或catalina.bat，具体取决于你的操作系统）。

将以下属性添加到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决一些信任库/密钥库问题。我发现非常有助于轻松查看/修改信任/密钥库的工具是keystore explorer。
