linux(ubuntu)下运行shadowsocks客户端

最终一键脚本：ssc-1key-linux

系统： Ubuntu 22.04

shadowsocks相关

1. 将系统更新到最新版
2. 安装shadowsocks及必要组件
   pip install https://github.com/shadowsocks/shadowsocks/archive/master.zip -U
   sudo apt-get install -y libsodium*
3. 配置shadowsocks client
   sudo vi /etc/shadowsocks.json

{
  "server": "您服务器地址",
  "server_port": 9999,
  "local_address": "127.0.0.1",
  "local_port": 1080,
  "password": "密码",
  "timeout": 600,
  "method": "aes-256-cfb"
}

3. 解决sodium库问题
   sudo ln -s /usr/lib/x86_64-linux-gnu/libsodium.a /usr/lib/x86_64-linux-gnu/liblibsodium.a

4. 设置路径权限
   sudo chmod 777 /var/log
   sudo chmod 777 /var/run

5. shadowsocks 开机自启动
   sudo vim /etc/systemd/system/shadowsocks.service:

   Description=Shadowsocks Client Service
   After=network.target
   [Service]
   Type=simple
   User=root
   ExecStart=/usr/local/bin/sslocal -c /etc/shadowsocks.json restart
   [Install]
   WantedBy=multi-user.target

   systemctl enable shadowsocks.service

HTTP全局代理

实现全局代理，我们可以使用polipo

1. polipo 安装
   wget http://archive.ubuntu.com/ubuntu/pool/universe/p/polipo/polipo_1.1.1-8_amd64.deb
   安装 sudo dpkg -i polipo_1.1.1-8_amd64.deb
   配置 vi /etc/polipo/config

   logSyslog = true
   logFile = /var/log/polipo/polipo.log
   proxyAddress = "0.0.0.0"
   socksParentProxy = "127.0.0.1:1080"
   socksProxyType = socks5
   chunkHighMark = 50331648
   objectHighMark = 16384
   serverMaxSlots = 64
   serverSlots = 16
   serverSlots1 = 32

   polipo安装后会自动运行。

2. 通过polipo设置本地http代理

   export http_proxy=http://127.0.0.1:8123
   export https_proxy=http://127.0.0.1:8123

   取消代理
   unset http_proxy
   unset https_proxy

pac代理

如果想使用http下的pac机制，可以考虑用provoxy替换polipo

1. provoxy 安装
   安装：sudo apt-get install -y privoxy
   cp /etc/privoxy/config /etc/privoxy/config.bak
   vim /etc/privoxy/config
   确保 listen-address 127.0.0.1:8118 打开
   在/etc/profile, ~/.bashrc,~/.bash_profile 中添加：

   proxy="http://127.0.0.1:8118"
   export https_proxy=$proxy
   export http_proxy=$proxy
   export ftp_proxy=$proxy

   systemctl enable privoxy
   systemctl restart privoxy

2. GFWList2Privoxy 制作pac条目
   pip install gfwlist2privoxy
   添加自定义域名：在生成的gfwlist.action文件中添加需要通过proxy访问的域名
   使pac生效：在/etc/privoxy/config文件中加上actionsfile gfwlist.action，然后重启privoxy服务

issue shooting:

1. AttributeError: module 'collections' has no attribute 'MutableMapping'
   解决：/home/zcj/.local/lib/python3.10/site-packages/shadowsocks/lru_cache.py 34行 MutableMapping前面加上abc.
2. [Errno 2] No such file or directory: b'liblibsodium.a'
   解决：sudo ln -s /usr/lib/x86_64-linux-gnu/libsodium.a /usr/lib/x86_64-linux-gnu/liblibsodium.a
