Linux环境安装配置Clash工具，以实现代理上网效果。包含下载、安装、配置、运行、测试以及开机自启动、定期自动更新订阅功能的操作文档，希望对你有所帮助。
一、下载clash for linux
- https://github.com/Dreamacro/clash/releases
- 下载时需注意服务器位数是64还是32位，本文档中使用的64位
- 命令执行过程（仅供参考,请按本地设置稍作调整）

打开系统设置，点击网络代理右边的 ⚙ 按钮，选择手动，填写 HTTP 和 HTTPS 代理为 127.0.0.1:7890，填写 Socks 主机为 127.0.0.1:7891，即可启用系统代理，如下图所示。
- 通过curl命令访问www.google.com，响应正常。
- 部分（我的TnT）服务器会出现curl可通，ping不通的情况，求大神告知~
touch /etc/systemd/system/clash.service
打开service文件
vi /etc/systemd/system/clash.service
填入以下内容**(注意修改clash文件夹路径)**
[Unit]
Description=clash daemon
[Service]
Type=simple
User=root
ExecStart=/opt/clash/clash -d /opt/clash/clash/
Restart=on-failure
[Install]
WantedBy=multi-user.target
保存并退出
systemctl start clash.service
systemctl enable clash.service
systemctl start clash.service
systemctl restart clash.service
systemctl status clash.service
- Clash For Linux 到目前为止没有自动订阅方式，我们做一个计划任务实现更新
config.yaml - 用Cron执行计划任务
[root@localhost ~]# crontab -e- 填入以下内容
29 6 * * * root pgrep clash | xargs kill -s 9
30 6 * * * root mv /opt/clash/config.yaml /opt/clash/configbackup.yaml
31 6 * * * root wget -P /opt/clash/ -O config.yaml [你的订阅链接]
32 6 * * * root nohup /opt/clash/clash -d /opt/clash/- 按Esc和:wq保存退出
- 重启crontab，使配置生效
[root@localhost ~]# systemctl restart crond.service- https://askubuntu.com/questions/903514/command-to-set-socks-proxy
