shadowsocks 服务端安装指南

官方地址：

shadowsocks/shadowsocks-libev: Bug-fix-only libev port of shadowsocks. Future development moved to shadowsocks-rust (github.com)

旧地址，不再更新：

shadowsocks/shadowsocks at master (github.com)

clowwindy/shadowsocks-libev at master (github.com)

本文基于Ubuntu。

install

$ sudo apt install shadowsocks-libev
...
Created symlink /etc/systemd/system/multi-user.target.wants/shadowsocks-libev.service → /lib/systemd/system/shadowsocks-libev.service.

Configuration

官方文档说配置文件在这里：

Edit your config.json file. By default, it’s located in /usr/local/etc/shadowsocks-libev.

但我的不是。

编辑/etc/shadowsocks-libev/config.json

{
    "server":"0.0.0.0",
    "mode":"tcp_and_udp",
    "server_port":your-port,
    "password":"your-pass",
    "timeout":300,
    "method":"chacha20-ietf-poly1305"
}

mode有三种：tcp_only，udp_only，tcp_and_udp。

“server”:“0.0.0.0” //只使用ipv4

“server”:["::0",“0.0.0.0”] //使用ipv6和ipv4

server-port: 这个端口我之前用的443，因为公司网络只给了80和443出口。但是用443的时候很慢或者根本翻不出去，v2RayN日志如下：

app/proxyman/outbound: failed to process outbound traffic > proxy/shadowsocks: failed to find an available destination > common/retry: [dial tcp x.x.x.x:443: i/o timeout dial tcp x.x.x.x:443: operation was canceled] > common/retry: all retry attempts failed

换成别的端口如8888就可以了。80没试。

默认的 "server":["::1", "127.0.0.1"]不行。

删掉了"local_port":1080，服务端不需要。

加速

Using TCP BBR¹

echo net.core.default_qdisc=fq >> /etc/sysctl.conf
echo net.ipv4.tcp_congestion_control=bbr >> /etc/sysctl.conf
sysctl -p
sysctl net.ipv4.tcp_available_congestion_control

开机启动

sudo systemctl enable shadowsocks-libev.service
# 禁用开机启动
sudo systemctl disable shadowsocks-libev.service

官方文档做法：

To enable shadowsocks-libev, add the following rc variable to your /etc/rc.conf file:

1	shadowsocks_libev_enable="YES"

Run

Start the Shadowsocks server:

systemctrl start shadowsocks-libev.service
# 或者
service shadowsocks-libev start

提示

shadowsocks的服务器在v2rayNG app上无法使用，需使用Shadowsocks app。但是PC上的v2rayN可以使用ss服务器。
