CentOS环境下tomcat启动超级慢的解决方案

tomcat日志中的其中一行:
Creation of SecureRandom instance for session ID generation using [SHA1PRNG] took [341,502] milliseconds

总启动时间:

INFO: Starting ProtocolHandler ["http-bio-8080"]
Aug 05, 2017 12:11:35 PM org.apache.coyote.AbstractProtocol start
INFO: Starting ProtocolHandler ["ajp-bio-8009"]
Aug 05, 2017 12:11:35 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 366680 ms

打开$JAVA_PATH/jre/lib/security/java.security这个文件,找到下面的内容:
securerandom.source=file:/dev/urandom
替换成
securerandom.source=file:/dev/./urandom
