tomcat启动一直卡在Root WebApplicationContext: initialization completed

解决方案

apt-get -y rng-tools
systemctl start rngd
cp /usr/lib/systemd/system/rngd.service /etc/systemd/system
vi /etc/systemd/system/rngd.service
找到ExecStart 在最后加上-r /dev/urandom

ExecStart=/sbin/rngd -f -r /dev/urandom

systemctl daemon-reload

systemctl restart rngd
