Linux服务器tomact 8.0启动慢的完美解决方法
环境信息：
CentOSrelease6.8
tomcat-8.0
JDK1.8
一、启动tomcat
#sh/root/tomcat-8.0/bin/startup.sh #tailf/root/tomcat-8.0/logs/catalina.out

等待tomcat启动的过程是煎熬的，足足5/6分钟，在不抱希望的情况下它居然又启动完成了......
有两种解决办法：
1）在Tomcat环境中解决
在catalina.sh中加入这么一行：
-Djava.security.egd=file:/dev/./urandom
例如：
JAVA_OPTS="-server-Xms2048m-Xmx4096m-XX:PermSize=256M-XX:MaxPermSize=512m-Djava.security.egd=file:/dev/./urandom"
2）在JVM环境中解决
修改$JAVA_PATH/jre/lib/security/java.security
securerandom.source=file:/dev/urandom
替换成
securerandom.source=file:/dev/./urandom
