docker部署hyperf项目负载均衡配置

由于hyperf是基于swoole常驻内存框架，每次更新代码都需要重启服务，这里通过负载均衡实现不停服务更新代码

###### 推荐使用docker swarm部署

首先用docker起两个容器这边容器名称分别是hyperf、hyperf2

映射到主机的端口分别是9551和9552

nginx配置：

# 至少需要一个 Hyperf 节点，多个配置多行
upstream hyperf_servers {
    # f容器名:端口 权重
    server hyperf:9501 weight=50;
    server hyperf2:9502 weight=50;
	server hyperf3:9505 backup;
}

server {
    # 监听端口
    listen 80;
    # 绑定的域名，填写您的域名
    server_name test.hyperf.com;

    location / {
        # 将客户端的 Host 和 IP 信息一并转发到对应节点
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        # 转发Cookie，设置 SameSite
        proxy_cookie_path / "/; secure; HttpOnly; SameSite=strict";

        # 执行代理访问真实服务器
        proxy_pass http://hyperf_servers;
    }
}

#通过其他域名代理跳转
server {
    listen       80;
    server_name  ultron.mijian360.host;
    root   /www/ultron/public;
    index  index.php index.html index.htm;
    #charset koi8-r;
    
    access_log /dev/null;
    #access_log  /var/log/nginx/nginx.ultron.access.log  main;
    error_log  /var/log/nginx/nginx.ultron.error.log  warn;
    
    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
	

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location /hyperf/api {
        # 执行代理访问真实服务器
        proxy_pass http://test.hyperf.com/;
       # proxy_pass http://test.hyperf.com/index;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        fastcgi_pass   php:9000;
        include        fastcgi-php.conf;
        include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

通过命令访问 curl http://test.hyperf.com/ 或者浏览器访问http://test.hyperf.com/ 结果如下： 当修改代码的时候可以执行以下shell，达到平滑启动的效果

#!/bin/bash
set -e
#重启hyperf容器
docker exec -it hyperf /bin/sh -c "composer dump-autoload -o && php bin/hyperf.php && exit"
docker restart hyperf
# 检测端口是否可访问
check_port() {
  nc -zv 127.0.0.1 9551 >/dev/null 2>&1
}

# 执行命令，重启hyperf2容器
execute_command() {
  docker exec -it hyperf2 /bin/sh -c "composer dump-autoload -o && php bin/hyperf.php && exit"
  docker restart hyperf2
}

# 循环最多一分钟检测端口是否可访问
start_time=$(date +%s)
while ! check_port; do
  sleep 1
  current_time=$(date +%s)
  elapsed_time=$((current_time - start_time))
  if [ $elapsed_time -gt 60 ]; then
    echo "Port 9551 is not accessible after 60 seconds, exiting..."
    exit 1
  fi
done

# 当端口可访问时执行命令
execute_command
