解決tomcat6.0.33 配置SSL時報“No Certificate file specified or invalid file format”異常

在配置tomcat的SSL雙向握手中，由於6.0.33版本中默認啓用了APR（APR是通過JNI訪問的可移植庫，可以提高Tomcat的性能和伸縮性），所以採用傳統的配置方式（如下）會報異常；

 

傳統的SSL配置：

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           clientAuth="true" sslProtocol="TLS"
           keystoreFile="conf/keystore/test.jks" keystorePass="111111"
           truststoreFile="conf/keystore/test.jks"   truststorePass="111111"

 

 

 

異常如下：

2011-10-27 9:26:03 org.apache.coyote.http11.Http11AprProtocol init

 解決辦法是採用下面的配置：

<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           clientAuth="true" sslProtocol="TLS"
           keystoreFile="conf/keystore/testpsira.jks" keystorePass="111111"
           truststoreFile="conf/keystore/testpsira.jks"   truststorePass="111111"

其實就是將protocol="HTTP/1.1"替換爲protocol="org.apache.coyote.http11.Http11Protocol"，問題得以解決；

APR給Tomcat的性能提升起到很大作用，建議配置APR方式。

 

題外話：

如果辨別Tomcat是否採用APR：

啓動Tomcat時，如果採用APR，日誌中會有如下信息：

信息: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].

 

如果沒有采用APR，啓動時則顯示類似的信息：

信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: ....後面省略

 

Tomcat6.0.33版本自動集成了APR，之前的版本沒有集成，需要手工配置，網上搜索會有很多這方面的教程。
