title: 【记录】GOST 进行 SOCKS5 的负载均衡

excerpt: 这段文本主要是关于准备工作、负载均衡、健康检查和定时检查的内容。首先是创建一个名为"cswitch"的docker网络，并使用alpine/curl容器测试SOCKS5转QUIC的连接。然后是设置负载均衡，创建一个名为"gost"的容器，并将其映射到8580端口，使用ginuerzh/gost镜像，并配置连接到hysteria01和hysteria02的SOCKS5代理。接下来是健康检查，创建一个名为Health_check.sh的脚本，用于定期检查连接到hysteria01的健康状态，并在失败时重新启动。最后是定时检查，设置定时任务来运行Health_check.sh脚本，并重新配置postfix以接收通知邮件。

## 准备工作
+ [SOCKS5 转 QUIC](/-ji-lu-SOCKS5-zhuan-QUIC)
```bash
sudo docker network create cswitch
sudo docker run --rm --net=cswitch alpine/curl --socks5-hostname hysteria01:1580 https://myip.ipip.net
sudo docker run --rm --net=cswitch alpine/curl --socks5-hostname hysteria02:1580 https://myip.ipip.net
```
## 负载均衡
```bash
mkdir -p ~/app/gost && cd ~/app/gost && nano docker-compose.yml
sudo docker-compose up -d && sudo docker-compose logs
sudo docker run --rm --net=cswitch alpine/curl --socks5-hostname gost:8580 https://myip.ipip.net
```
```yml
version: '3.3'
services:
  gost:
    restart: unless-stopped
    ports:
      - '8580:8580'
    image: ginuerzh/gost
    command: -L=:8580 -F=socks5://localhost:1580?ip=hysteria01:1580,hysteria02:1580
  
networks:
  default:
    external: true
    name: cswitch
```
## 健康检查
```bash
nano Health_check.sh
# chmod +x Health_check.sh 
# dos2unix Health_check.sh 
/home/limour/app/hysteria01/Health_check.sh
```
```bash
#!/bin/bash

COMPOSE_FILE=/home/limour/app/hysteria01/docker-compose.yml

while true; do
    output=$(sudo docker run --rm --net=cswitch alpine/curl -fs --socks5-hostname hysteria01:1580 https://www.google.com/robots.txt)
    if [ $? -eq 0 ]; then
        echo "Health check successful"
    else
        echo "Health check failed"
        sudo docker-compose -f $COMPOSE_FILE restart
    fi
    sleep 300
done
```
## 定时检查
```bash
nano Health_check.sh
# chmod +x Health_check.sh 
# dos2unix Health_check.sh 
/home/limour/app/hysteria01/Health_check.sh
crontab -e
* * * * * /usr/bin/sudo /home/limour/app/hysteria01/Health_check.sh
* * * * * /usr/bin/sudo /home/limour/app/hysteria02/Health_check.sh
crontab -l
# sudo dpkg-reconfigure postfix
tail /var/spool/mail/limour
```
```bash
#!/bin/bash

COMPOSE_FILE=/home/limour/app/hysteria02/docker-compose.yml

output=$(sudo docker run --rm --net=cswitch alpine/curl -fs --socks5-hostname hysteria02:1580 https://www.google.com/robots.txt)
if [ $? -eq 0 ]; then
	echo "Health check successful"
else
	echo "Health check failed"
	sudo docker-compose -f $COMPOSE_FILE restart
fi
```
