2/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el6_10.x86_64-debug/jre/lib/security/java.security
3/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el6_10.x86_64/jre/lib/security/java.security

二、打开 java.security 文件

1[root@ecs-s6-xlarge-2-linux-20191210145334 shanhe]# vi /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el6_10.x86_64/jre/lib/security/java.security

三、修改“securerandom.source=file:/dev/random”为“securerandom.source=file:/dev/./urandom”
