一键安装SSR服务器

（来自https://www.91yun.org/archives/2079）

一键安装命令:
wget -N --no-check-certificate https://raw.githubusercontent.com/91yun/shadowsocks_install/master/shadowsocksR.sh && bash shadowsocksR.sh

安装完成后，显示：
Congratulations, ShadowsocksR install completed!
Server IP:  你的服务器的ip
Server Port:  7979(你所设置的端口号）
Password:  你设置的密码
Protocol:  auth_sha1_v4
obfs:  tls1.2_ticket_auth
Encryption Method:  chacha20
Welcome to visit:https://www.91yun.org/archives/2079

卸载命令
./shadowsocksR.sh uninstall

升级命令
cd /usr/local/shadowsocks/shadowsocks
git pull

默认配置
加密：chacha20
协议：auth_sha1_v2
混淆参数：tls1 .2_ticket_auth

配置客户端
通用说明
每个系统上的客户端虽然操作界面和操作方法有些许差异，但是基本的配置参数和配置方法是一致的：
提供服务器位址、端口號、密碼、加密方式、協議 (SSR專用)、混淆參數 (SSR專用)等的设置功能，这些参数都来自于我们在自己服务器上的设置，只要填入这些设置就能开始番羽土啬了。
提供全局 (全部走代理)、自动 (按照PAC自动选择)、关闭 (全部不走代理)、自定义 (自定义哪些网站走代理)这四种模式。对于大多数普通用户来说，建议选择自动模式就能满足我们的需求了。
提供二维码分享服务器配置，扫描二维码快速添加服务器的功能。只需要借助二维码就能快速配置服务器。
SSR 服务器和客户端均向下兼容SS，所以推荐安装支持SSR的客户端。

macOS
SSR客户端推荐：ShadowsocksX NG
SS客户端推荐：ShadowsocksX NG ( https://github.com/shadowsocks/ShadowsocksX-NG, 注意：其默认的端口号是1086！ )，ShadowsocksX(https://github.com/shadowsocks/shadowsocks-iOS/releases/download/2.6.3/ShadowsocksX-2.6.3.dmg)

Windows
SSR客户端推荐：ShadowsocksR
SS客户端推荐：Shadowsocks ( https://github.com/shadowsocks/shadowsocks-windows )

iOS
SSR客户端推荐：Shadowrocket ( https://itunes.apple.com/us/app/shadowrocket/id932747118，目前收费)，Wingy ( https://itunes.apple.com/us/app/id1178584911，目前免费)
SSR客户端备选：Surge ( https://itunes.apple.com/us/app/surge-web-developer-tool-proxy/id1040100637?mt=8 (中国区已下架)，官网-http://nssurge.com/，技术宅的神器)

Android
SSR客户端推荐：SSR
SS客户端推荐：影梭( https://play.google.com/store/apps/details?id=com.github.shadowsocks )

Linux 和其他系统
SSR客户端推荐：shadowsocksr-libev
SS客户端推荐：shadowsocks-libev ( https://github.com/shadowsocks/shadowsocks-libev )

一键安装锐速破解版（来自https://www.91yun.org/archives/683）

为什么要安装「锐速」？
锐速是服务器端的TCP单边加速工具，可以提高连接服务器的速度。锐速原本是收费软体，目前已经停止开发，只能安装破解版。除了锐速外，还有免费的Finalspeed，但是Finalspeed需要额外的客户端支援才能运作（双边加速），而锐速不需要额外的客户端就能运作。
支持CentOS、Ubuntu、Debain 系统，不支持Openvz 架构的VPS
一键安装命令（如果内核完全匹配就会自动下载安装）

wget -N --no-check-certificate https://raw.githubusercontent.com/91yun/serverspeeder/master/serverspeeder-all.sh && bash serverspeeder-all.sh

一键卸载命令:
chattr -i /serverspeeder/etc/apx* && /serverspeeder/bin/serverSpeeder.sh uninstall -f

ShadowsocksR一键安装脚本


本脚本适用环境：
系统支持：CentOS，Debian，Ubuntu
内存要求：≥128M
日期：2017 年 07 月 27 日

关于本脚本：
一键安装 ShadowsocksR 服务端。
请下载与之配套的客户端程序来连接。
（以下客户端只有 Windows 客户端和 Python 版客户端可以使用 SSR 新特性，其他原版客户端只能以兼容的方式连接 SSR 服务器）

默认配置：
服务器端口：自己设定（如不设定，默认为 8989）
密码：自己设定（如不设定，默认为 teddysun.com）
加密方式：自己设定（如不设定，默认为 aes-256-cfb）
协议（Protocol）：自己设定（如不设定，默认为 origin）
混淆（obfs）：自己设定（如不设定，默认为 plain）

客户端下载：
Windows / OS X
Linux
Android / iOS
OpenWRT

使用方法：
使用root用户登录，运行以下命令：
wget --no-check-certificate https://raw.githubusercontent.com/teddysun/shadowsocks_install/master/shadowsocksR.sh
chmod +x shadowsocksR.sh
./shadowsocksR.sh 2>&1 | tee shadowsocksR.log


安装完成后，脚本提示如下：
Congratulations, ShadowsocksR server install completed!
Your Server IP        :your_server_ip
Your Server Port      :your_server_port
Your Password         :your_password
Your Protocol         :your_protocol
Your obfs             :your_obfs
Your Encryption Method:your_encryption_method

Welcome to visit:https://shadowsocks.be/9.html
Enjoy it!


卸载方法：
使用 root 用户登录，运行以下命令：
./shadowsocksR.sh uninstall


安装完成后即已后台启动 ShadowsocksR ，运行：
/etc/init.d/shadowsocks status


可以查看 ShadowsocksR 进程是否已经启动。
本脚本安装完成后，已将 ShadowsocksR 自动加入开机自启动。

使用命令：
启动：/etc/init.d/shadowsocks start
停止：/etc/init.d/shadowsocks stop
重启：/etc/init.d/shadowsocks restart
状态：/etc/init.d/shadowsocks status

配置文件路径：/etc/shadowsocks.json
日志文件路径：/var/log/shadowsocks.log
代码安装目录：/usr/local/shadowsocks

多用户配置示例：
{
"server":"0.0.0.0",
"server_ipv6": "[::]",
"local_address":"127.0.0.1",
"local_port":1080,
"port_password":{
    "8989":"password1",
    "8990":"password2",
    "8991":"password3"
},
"timeout":300,
"method":"aes-256-cfb",
"protocol": "origin",
"protocol_param": "",
"obfs": "plain",
"obfs_param": "",
"redirect": "",
"dns_ipv6": false,
"fast_open": false,
"workers": 1
}

更新日志：
2017 年 07 月 27 日：
1、新增：可选协议（protocol）auth_chain_b 。使用该协议需更新到最新版（4.7.0）ShadowsocksR 版客户端；
2、修改：更新 ShadowsocksR 源码下载地址。

2017 年 07 月 22 日：
1、新增：安装时可选 13 种加密方式的其中之一（none 是不加密）。如下所示：
none
aes-256-cfb

aes-256-cfb8
aes-192-cfb8
aes-128-cfb8
aes-256-ctr
aes-192-ctr
aes-128-ctr
chacha20-ietf
chacha20
rc4-md5
rc4-md5-6


2、新增：安装时可选 7 种协议（protocol）的其中之一。如下所示：
origin
verify_deflate
auth_sha1_v4
auth_sha1_v4_compatible
