解决方案：

1、网上有贴，说关闭ssl 即可：

   修改server.xml

<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" />

2、但如果确实需要SSL的话怎么办？得从根本上解决问题：

 a、yum install openssl-devel

 b、yum groupinstall "Development Tools"

 c、yum apr apr-util

 d、解压$TOMCAT_HOME/bin目录下tomcat-native.tar.gz 文件

 e、进入 cd tomcat-native-1.1.31-src/jni/native/目录：

   如果运行./configure，出现如下情况

[root@root native]# ./configure

则：

f、make && make install

g、重启tomcat
