acme协议从letsencrypt生成免费的证书
#!/usr/bin/env sh
# https://github.com/Neilpang/acme.sh/wiki/说明
# 安装ssl依赖 和 acme.sh工具
apt-get install socat netcat -y
curl https://get.acme.sh | sh
# 设置域名
DOMAIN=ssl.srgb888.ga
# 生成域名ssl证书
~/.acme.sh/acme.sh --issue -d ${DOMAIN} --webroot /var/www/html --standalone -k ec-256 --force
如果你用的nginx服务器,以后可以使用一行命令更新证书
~/.acme.sh/acme.sh --issue -d ssl.srgb888.ga --nginx --standalone -k ec-256 --force
Linux 使用代理 加速git 和安装软件
#!/bin/bash
# socks5tohttp.sh
brook socks5tohttp -s 127.0.0.1:1080 -l 0.0.0.0:8010 &
ps aux | grep -E brook
export http_proxy="http://127.0.0.1:8010"
export https_proxy="http://127.0.0.1:8010"
- Windows 系统脚本 VPN --> socks5 --> http代理 给手机使用
:: Brook 开启 socks5 再转http
start /b brook socks5 -l :1080 -i 0.0.0.0
sleep 1
start /b brook socks5tohttp -s 127.0.0.1:1080 -l 0.0.0.0:8010
安装 brook 用来 Socks5 转 HTTP 代理
- brook 其他更多使用方法访问 官方网站
$ curl -L https://github.com/txthinking/brook/releases/download/v20200909/brook_linux_amd64 -o /usr/bin/brook
$ chmod +x /usr/bin/brook
# 32位系统安装
$ curl -L https://github.com/txthinking/brook/releases/download/v20200909/brook_linux_386 -o /usr/bin/brook
- Socks5 转 HTTP 代理
$ brook socks5tohttp -s 127.0.0.1:1080 -l 127.0.0.1:8010
- 中继: 可以将地址中继到远程地址。 它可以中继任何tcp和udp服务器
$ brook relay -f :9999 -t 1.2.3.4:9999
- brook socks5 运行一个独立的标准socks5服务器(TCP和UDP)
$ brook socks5 -l :1080 -i 0.0.0.0
Linux 让终端走代理的几种方法
ssh保持长连接的方式,方法有以下三种:
1.修改server端的etc/ssh/sshd_config
ClientAliveInterval 60 #server每隔60秒发送一次请求给client,然后client响应,从而保持连接
ClientAliveCountMax 3 #server发出请求后,客户端没有响应得次数达到3,就自动断开连接,正常情况下,client不会不响应
systemctl reload sshd
2.修改client端的etc/ssh/ssh_config添加以下:(在没有权限改server配置的情形下)
ServerAliveInterval 60 #client每隔60秒发送一次请求给server,然后server响应,从而保持连接
ServerAliveCountMax 3 #client发出请求后,服务器端没有响应得次数达到3,就自动断开连接,正常情况下,server不会不响应
3.在命令参数里ssh -o ServerAliveInterval=60 这样子只会在需要的连接中保持持久连接, 毕竟不是所有连接都要保持持久的
