tomcat启动卡主不动

为什么80%的码农都做不了架构师？>>>

在这边一直卡主了

 

修改Java.security文件，在文件中找到securerandom.source这个设置项

# The entropy gathering device can also be specified with the System
# property "java.security.egd". For example:
#
#   % java -Djava.security.egd=file:/dev/random MainClass
#
# Specifying this System property will override the
# "securerandom.source" Security property.
#
# In addition, if "file:/dev/random" or "file:/dev/urandom" is
# specified, the "NativePRNG" implementation will be more preferred than
# SHA1PRNG in the Sun provider.
#
securerandom.source=file:/dev/random

将/dev/random 改成/dev/urandom
