在Windows Server 上搭建Shadowsocks服务器

发表评论

这里是在windows上搭建Shadowsocks服务器，使用的是github上的libQtShadowsocks项目。
项目地址：https://github.com/shadowsocks/libQtShadowsocks

准备

一台可以翻墙的windows。

下载libQtShadowsocks

从https://github.com/shadowsocks/libQtShadowsocks/releases下载一个已经编译好的版本，这里是shadowsocks-libqss-v2.0.2-win64.7z。
下载后解压到任意位置，里面就一个shadowsocks-libqss.exe文件。

配置文件

在解压目录下创建2个文件，一个config.json，一个shadowsocks-server.bat。
config.json放置配置信息。
内容如下：

1
2
3
4
5
6
7
8
9
10
11
{
“server”:”0.0.0.0″,
“server_port”:8023,
“local_address”:”127.0.0.1″,
“local_port”:1080,
“password”:”password”,
“timeout”:600,
“method”:”aes-256-cfb”,
“http_proxy”: false,
“auth”: false
}

配置说明：
server
the address your server listens（服务器IP）
local_address
the address your local listens（本地代理地址）
local_port
local port（本地代理端口）（写之前创建的ss的端口）
port_password
password used for encryption(自己设定的服务器端口和密码)（自己可以随便设定）
timeout
in seconds（超时断开，以秒为单位）
method
default: “aes-256-cfb”, see Encryption（加密方式）
fast_open
use TCP_FASTOPEN, true / false（是否使用TCP）
workers
number of workers, available on Unix/Linux（这个只在Unix和Linux下有用，可不设置）。

shadowsocks-server.bat内容如下：

1
2
@echo off
shadowsocks-libqss.exe -c config.json -S

运行Shadowsocks服务

直接运行shadowsocks-server.bat即可运行Shadowsocks服务，你也可以在命令提示符进入软件目录，运行shadowsocks-libqss.exe -c config.json -S这行命令。

客户端配置

这里使用的客户端为Shadowsocks，github地址：https://github.com/shadowsocks/shadowsocks-windows。

注意：要以PAC模式运行，如果选择全局模式，所有的访问都会使用shadowsocks；如果选择了PaC模式，则只有pac.txt中的网址才会使用shadowsocks。

注意防火墙开通相应的端口。

自定义规则

参考：http://honglu.me/2015/06/26/ShadowSocks%E8%87%AA%E5%AE%9A%E4%B9%89%E8%A7%84%E5%88%99/
从网上查阅的资料
编辑FGWList的用户规则


但我本地最后从FGWList更新本地pac时报错了

所以我是直接修改的pac.txt文件，在其中加入你想使用shadowsocks访问的网址，最后选择使用PAC模式即可。

多用户

如果希望多个用户使用shadowsocks服务，使用下面的配置替换password:xxx部分。

1

“port_password”: {
“8381”: “foobar1”,

更换了算法、端口还是不行，客户端更新版本也不行，最后更新服务端版本后ok了。这里使用的版本是：shadowsocks-libqss-v2.0.2-win64.7z。

PS：有问题先看看github上相关的Issues。

It is recommended that you start the service at boot time so that job can run w/o problems.

If you are using Redhat (RHEL)/Fedora Core/Cent OS Linux use the following commands to ensure that the service remains enabled after a reboot:
# chkconfig crond on
You can use a text based GUI tool called ntsysv to enable crond service:
# ntsysv

If you are using Debian or Ubuntu Linux use the following commands to ensure that the service remains enabled after a reboot:
# rcconf
OR
$ sudo rcconf
You can use command line tool update-rc.d:
# update-rc.d cron defaults
OR
$ sudo update-rc.d cron defaults

Centos7 配置静态路由

发表评论 
# 在centos7中配置如下：  

临时配置的方法：

　　172.168.10.0/24 主机配置：

ip route add 172.168.20.0/24 via 172.168.10.254 dev ens4  
 # 当eno4接口访问172.168.20.0/24 网络请转到 172.168.10.254 接口
   172.168.20.0/24 主机配置：  

ip route add 172.168.10.0/24 via 172.168.20.254 dev eno4  
当 eno4 接口访问172.168.10.0/24 网络请转到 172.168.20.254 接口
如上分别在两个不同网段主机上配置后，两台主机才会互联互通。
在 Centos7配置永久生效方式如下：  

    # cat /etc/sysconfig/network-scripts/route-ens4 
    172.168.20.0/24 via 172.168.10.254 dev eno4

    需要手动创建一个配置文件 route-网卡名，内容为临时配置 add 后面的内容，另一台主机同样的方式进行配置。

将下面代码中的第一句中的Vicer改为自己将要设置的密码. 否则默认root密码为Vicer.
创建instance时,点击add launch script,将下列代码复制进去(注意更改root密码).

!/bin/bash
echo root:password |sudo chpasswd root
sudo sed -i 's/^#\?PermitRootLogin./PermitRootLogin yes/g' /etc/ssh/sshd_config; 
sudo sed -i 's/^#\?PasswordAuthentication./PasswordAuthentication yes/g' /etc/ssh/sshd_config;
sudo reboot


对于EC2,GCE等机器也可以使用. 不能添加代码的机器,可以登录进ssh,再执行上面的代码. 也可以开启root登陆.
