[langhaidian]

What version of shadowsocks-libev are you using?

3.0.4

What operating system are you using?

debian 4.9.14-040914-generic(AWS开的服务器)

What did you do?

ss-server运行命令提示如下：
This system doesn't provide enough entropy to quickly generate high-quality random numbers
Installing the rng-utils/rng-tools 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.

不太懂来问问，什么原因？

As it said,

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

Just install the rng-tool and use command rngd -r /dev/urandom

I'd like to recommend haveged, rather than rng-tool

@rogers0
How would you do it with haveged? Following command should work on Debian and Redhat based systems to install it:
yum install haveged -y 2>/dev/null||sudo apt-get install haveged -y 2>/dev/null
service haveged status shown it is running, but the ss-server continue to complain. Until i installed and ran rngd command suggested by Galaxy0419
