1 下载clash

sudo apt update

mkdir clash && cd clash

wget https://github.com/doreamon-design/clash/releases/download/v2.0.24/clash_2.0.24_linux_amd64.tar.gz

tar -zxvf clash_2.0.24_linux_amd64.tar.gz

chmod +x clash

# 运行该指令，会自动创建 ~/.config/ 目录和相关文件，执行后 Ctrl c 关闭
./clash

mkdir -p ~/.local/bin

cp clash ~/.local/bin/clash

2 放置配置文件

cd ~/.config/clash

# 我运行该指令，下载的文件是一堆字母，不可用，最后是直接从手机的clash上复制一份config.yaml过来的
curl -f "订阅链接" > config.yaml

3 创建service文件

cd /etc/systemd/system/

在该目录下创建文件 clash.service，文件内容如下：

# Copyright @TalentQ All Reserved.


[Unit]
Description=clash for linux

[Service]
Type=simple
User=talentq
# 这里修改成自己的绝对路径
ExecStart=/home/talentq/.local/bin/clash

[Install]
WantedBy=multi-user.target

4 设置开机自启动

# 重新加载systemd配置
sudo systemctl daemon-reload
# 设置开机自启动
sudo systemctl enable clash
# 此时重启电脑...
# 查看service状态
sudo systemctl status clash

5 Ubuntu设置

}

# start proxy
function proxy() {
    export no_proxy=localhost,127.0.0.0/8,::1
    export http_proxy=http://127.0.0.1:7890/
    export https_proxy=$http_proxy
    export NO_PROXY=$no_proxy
    export HTTP_PROXY=$http_proxy
    export HTTPS_PROXY=$http_proxy
    export ALL_PROXY=socks://127.0.0.1:7890/
    export all_proxy=socks://127.0.0.1:7890/
    terminal_proxy="on"
    echo -e "Terminal   proxy: $terminal_proxy\n"
    # echo -e "clash.service: $(get_clash_status)\n"
}

# stop proxy
function unproxy() {
    unset no_proxy http_proxy https_proxy NO_PROXY HTTP_PROXY HTTPS_PROXY ALL_PROXY all_proxy
    terminal_proxy="off"
    echo -e "Terminal   proxy: $terminal_proxy\n"
    # echo -e "clash.service: $(get_clash_status)\n"
}

# show proxy status
function proxy_status() {
    echo -e "********** current terminal's proxy **********\n"
    echo -e "Terminal   proxy: $terminal_proxy" 
    echo -e "clash.service: $(get_clash_status)\n"
    env | grep -E "proxy|PROXY" && echo ""
}

# show proxy ip info
function proxy_ip() {
    echo -e "Terminal   proxy: $terminal_proxy\n"
    echo -e "current ip info:"
    curl http://ip-api.com/json/ -s | jq . && echo ""
}

# default to close the terminal proxy
unproxy > /dev/null

# <<< proxy <<<
