安装前准备
sudo apt update sudo apt upgrade
安装shadowsocks-libev
shadowsocks二进制版，比python版效率高
sudo apt install shadowsocks-libev
安装v2ray-plugin
可访问https://github.com/shadowsocks/v2ray-plugin/releases获得下载地址
wget https://github.com/shadowsocks/v2ray-plugin/releases/download/v1.3.1/v2ray-plugin-linux-amd64-v1.3.1.tar.gz tar zxf v2ray-plugin-linux-amd64-v1.3.1.tar.gz sudo mv v2ray-plugin_linux_amd64 /usr/bin/v2ray-plugin
安装acme.sh
curl https://get.acme.sh | sh
申请证书
root用户
直接使用standalone模式申请证书。acme.sh脚本会自动开启一个临时web服务器，用于验证域名的所有权。
acme.sh --issue -d mydomain.me --standalone mkdir /root/certs //创建本地证书目录 acme.sh --install-cert -d mydomain.me --key-file /root/certs/mydomain.me.key --fullchain-file /root/certs/mydomain.me.cer --reloadcmd "sudo systemctl restart shadowsocks-libev"
非root用户
没有权限启动80端口的web服务器了，所以用nginx来处理web请求。
sudo apt install nginx sudo chown ubuntu:ubuntu /var/www/html acme.sh --issue -d mydomain.me --webroot /var/www/html sudo mkdir /home/gimhoy sudo mkdir /home/gimhoy/certs/ //创建本地证书目录 sudo chown ubuntu:ubuntu /home/gimhoy sudo chmod -R 777 /home/gimhoy chmod u+x /home/ubuntu/.acme.sh acme.sh --install-cert -d mydomain.me --key-file /home/gimhoy/certs/mydomain.me.key --cert-file /home/gimhoy/certs/mydomain.me.cer --reloadcmd "sudo systemctl restart shadowsocks-libev"
配置shadowsocks+v2ray
sudo vi /etc/shadowsocks-libev/config.json
{
"server":"::",
"server_port": 443,
"password": "mypwd",
"timeout":60,
"method":"chacha20-ietf-poly1305",
"mode":"tcp_and_udp",
"fast_open":true,
"plugin":"v2ray-plugin",
"plugin_opts":"server;tls;fast-open;host=mydomain.me;cert=/home/gimhoy/certs/mydomain.me.cer;key=/home/gimhoy/certs/mydomain.me.key;loglevel=none"
}
配置shadowsocks-libev.service
sudo vi /etc/systemd/system/shadowsocks-libev.service
[Unit] Description=Shadowsocks-libev Server After=network.target [Service] Type=simple ExecStart=/usr/bin/ss-server -c /etc/shadowsocks-libev/config.json -u Restart=on-abort [Install] WantedBy=multi-user.target
sudo systemctl start shadowsocks-libev sudo systemctl enable shadowsocks-libev
开启TCP BBR加速
需Linux kernel 4.9 及以上
modprobe tcp_bbr sudo sh -c "echo 'tcp_bbr' >> /etc/modules-load.d/modules.conf" sudo sh -c "echo 'net.core.default_qdisc=fq' >> /etc/sysctl.conf" sudo sh -c "echo 'net.ipv4.tcp_congestion_control=bbr' >> /etc/sysctl.conf" //重启 sudo sysctl -p //查看是否生效，若均有bbr，则开启BBR成功。 sysctl net.ipv4.tcp_available_congestion_control sysctl net.ipv4.tcp_congestion_control
优化吞吐量
sudo vi /etc/sysctl.d/local.conf
# max open files fs.file-max = 51200 # max read buffer net.core.rmem_max = 67108864 # max write buffer net.core.wmem_max = 67108864 # default read buffer net.core.rmem_default = 65536 # default write buffer net.core.wmem_default = 65536 # max processor input queue net.core.netdev_max_backlog = 4096 # max backlog net.core.somaxconn = 4096 # resist SYN flood attacks net.ipv4.tcp_syncookies = 1 # reuse timewait sockets when safe net.ipv4.tcp_tw_reuse = 1 # turn off fast timewait sockets recycling net.ipv4.tcp_tw_recycle = 0 # short FIN timeout net.ipv4.tcp_fin_timeout = 30 # short keepalive time net.ipv4.tcp_keepalive_time = 1200 # outbound port range net.ipv4.ip_local_port_range = 10000 65000 # max SYN backlog net.ipv4.tcp_max_syn_backlog = 4096 # max timewait sockets held by system simultaneously net.ipv4.tcp_max_tw_buckets = 5000 # turn on TCP Fast Open on both client and server side net.ipv4.tcp_fastopen = 3 # TCP receive buffer net.ipv4.tcp_rmem = 4096 87380 67108864 # TCP write buffer net.ipv4.tcp_wmem = 4096 65536 67108864 # turn on path MTU discovery net.ipv4.tcp_mtu_probing = 1
sudo sysctl --system //使配置生效
ulimit优化
sudo vi /etc/rc.local
ulimit -n 51200 //加在启动shadowsocks前
sudo sysctl --system //使配置生效
客户端配置
以Windows官方客户端（https://github.com/shadowsocks/shadowsocks-windows/releases）为例，在https://github.com/shadowsocks/v2ray-plugin/releases下载最新的windows-amd64版v2ray-plugin，解压，将里面的.exe文件改名为v2ray-plugin.exe，放置在shadowsocks的运行目录下，配置如图。
其他系统大同小异。
