shadowsocks是一套技术和相关工具的总称,常备简称为ss,可以简单总结为:一套基于Sock5代理方式的网络加密传输数据包的技术 = 用Socks5 技术加密的技术。
Sock技术简介
采用sock协议的代理服务器就是 Socks 服务器,是一种通用的代理服务器。
Socks代理与应用层代理、HTTP层代理不通,Socks代理只是简单的传递数据包,而不必关心是何种协议(比如FTP、HTTP和NNTP请求)。所以,Socks代理比其他应用层代理要快的多。
Sock5代理服务器则是把你的网络数据请求通过一条连接你和代理服务器之间的通道,由服务器转发到目的地。你没有加入任何新的网络,只是http/socks数据经过代理服务器的转发送出,并从代理服务器接收回应。你与代理服务器通信过程不会被额外处理,如果你用https,那本身就是加密的。
搭建:
1、参考安装教程:http://totoro.site/index.php/archives/54 ,按照该教程安装时,出现错误,根据错误提示,发现是 解压 mbedtls-2.13.0-gpl.tgz 时格式不对造成的,经过排查,该文件(mbedtls-2.13.0-gpl.tgz)不是一个压缩包,是一个ASCII文件,更改安装脚本中 mbedtls-2.13.0-gpl.tgz 的下载地址: https://down.24kplus.com/linux/mbedtls/mbedtls-2.16.3-gpl.tgz,然后重新执行脚本,安装完成。
2、安装 shadowsocks-libev.sh (网络上该脚本中一个网址不存在,已修改);添加执行权限后 执行便可: ./shadowsocks-libev.sh
3、增加用户:useradd ss3
4、添加子接口:ifconfig eth0:0 2.2.2.2/24 或 ip addr add 2.2.2.2/24 dev eth0 label eth0:0 清除网卡子接口,删除ip别名 ifconfig eth0:1 down 或 ip addr del 2.2.2.2/24 dev eth0 label eth0:0 ;
若是想永久生效,创建:/etc/sysconfig/network-scripts/ifcfg-eth0:0 添加:(文件中仅有下面四行便可)
DEVICE=eth0:0
IPADDR=2.2.2.2
PREFIX=24
ONPARENT=yes
注:使用命令添加后立刻生效,增加配置文件是在系统重启后生效,所以需要使用命令添加并且增加配置文件才可以立即增加且永久生效。
5、使用新建的用户运行:ss-server -a ss3 -c /home/ss3/ss3.json -u &
6、防火墙放行相应端口(tcp放行就可以了,但是网上教程都放行了udp)
iptables -I INPUT -p tcp --dport 14278 -j ACCEPT
或:firewall-cmd --permanent --zone=public --add-port=11126/tcp
7、查看是否成功启动并监听相应端口
ps -aux | grep ss-server
netstat -anlp | grep ss-server
8、若想中断某个ss-server进程,先通过 ps -aux 找到pid,之后通过 kill [pid] 强制中断。

可以将一下代码复制到Linux的一个脚本中,直接运行,便可安装好shadowsocks-libev
