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.
解決辦法:
yum 安裝 rng-tools
并在init的ss啟動(dòng)腳本中，ss-server啟動(dòng)前添加一行執(zhí)行語句rngd -r /dev/urandom
