Linux 安装 shadowsocks 服务器

安装 python

centos 8 已经自带 pytho3，如果你的 linux 版本较低，先升级 python

安装 Shadowsocks

pip install shadowsocks

启动停止

# 启动服务
# -p 端口，默认 8388
# -k 密码，默认 password
ssserver -p 8388 -k password -m aes-256-cfb --user nobody -d start

# 停止服务
ssserver -d stop

查看日志

tail -f /var/log/shadowsocks.log

错误处理

因为系统环境差异，在运行 ssserver 时可能会爆出以下错误

loading libcrypto from libcrypto.so.1.1
Traceback (most recent call last):

AttributeError: /lib64/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup

这是因为 openssl 版本升级造成的不兼容

函数 EVP_CIPHER_CTX_cleanup 在 1.1.0 版本中替换成为 EVP_CIPHER_CTX_reset

根据错误提示，将 /usr/local/lib/python3.6/site-packages/shadowsocks/crypto/openssl.py 里的 EVP_CIPHER_CTX_cleanup 替换为 EVP_CIPHER_CTX_reset 即可
