This system doesn't provide enough entropy to quickly generate high-quality random numbers.

Installing the rng-utils/rng-tools, jitterentropy or haveged packages may help.

On virtualized Linux environments, also consider using virtio-rng.

The service will not start until enough entropy has been collected.

解决办法:

yum 安装 rng-tools

并在init的ss启动脚本中，ss-server启动前添加一行执行语句rngd -r /dev/urandom
