宝塔nginx配置SpringBoot服务集群代理

1、需求：

现有一个springboot服务需要部署成集群，通过nginx负载均衡进行访问，其中这个springboot服务内置了MQTT服务、HTTP服务、TCP服务。

MQTT服务开放了1889端口

HTTP服务开放了8891端口

HTTP服务开放了8893端口

TCP服务开放了8893端口

该服务在宝塔部署启动后开启的端口

2、nginx代理部署后的集群服务

宝塔nginx的nginx.conf位置

/www/server/nginx/conf/nginx.conf

nginx.conf原始内容：

user  www www;
worker_processes auto;
error_log  /www/wwwlogs/nginx_error.log  crit;
pid        /www/server/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;stream {log_format tcp_format '$time_local|$remote_addr|$protocol|$status|$bytes_sent|$bytes_received|$session_time|$upstream_addr|$upstream_bytes_sent|$upstream_bytes_received|$upstream_connect_time';access_log /www/wwwlogs/tcp-access.log tcp_format;error_log /www/wwwlogs/tcp-error.log;include /www/server/panel/vhost/nginx/tcp/*.conf;
}events{use epoll;worker_connections 51200;multi_accept on;}http{include       mime.types;#include luawaf.conf;include proxy.conf;default_type  application/octet-stream;server_names_hash_bucket_size 512;client_header_buffer_size 32k;large_client_header_buffers 4 32k;client_max_body_size 50m;sendfile   on;tcp_nopush on;keepalive_timeout 60;tcp_nodelay on;fastcgi_connect_timeout 300;fastcgi_send_timeout 300;fastcgi_read_timeout 300;fastcgi_buffer_size 64k;fastcgi_buffers 4 64k;fastcgi_busy_buffers_size 128k;fastcgi_temp_file_write_size 256k;fastcgi_intercept_errors on;gzip on;gzip_min_length  1k;gzip_buffers     4 16k;gzip_http_version 1.1;gzip_comp_level 2;gzip_types     text/plain application/javascript application/x-javascript text/javascript text/css application/xml;gzip_vary on;gzip_proxied   expired no-cache no-store private auth;gzip_disable   "MSIE [1-6]\.";limit_conn_zone $binary_remote_addr zone=perip:10m;limit_conn_zone $server_name zone=perserver:10m;server_tokens off;access_log off;server{listen 888;server_name phpmyadmin;index index.html index.htm index.php;root  /www/server/phpmyadmin;#error_page   404   /404.html;include enable-php.conf;location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)${expires      30d;}location ~ .*\.(js|css)?${expires      12h;}location ~ /\.{deny all;}access_log  /www/wwwlogs/access.log;}
include /www/server/panel/vhost/nginx/*.conf;
}

文件中的 include /www/server/panel/vhost/nginx/tcp/*.conf;表明了nginx加载.conf文件的位置，我们要配置集群代理，需要

在/www/server/panel/vhost/nginx/这个目录下面配置多个.conf文件，即可完成需求。

a、修改java_veiplinks-standalone.conf

upstream iotserver {server 192.168.0.26:8844;server 192.168.0.27:8844;server 192.168.0.28:8844;server 192.168.0.107:8848;server 192.168.0.104:8848;
}upstream fileserver {
#  server 192.168.0.26:8844; #此处指定文件上传到该服务器上server 192.168.0.107:8848;
}server {listen       80;server_name  iot_server # gzip configgzip on;gzip_min_length 1k;gzip_comp_level 9;gzip_types text/plain text/css text/javascript application/json application/javascript application/x-javascript application/xml;gzip_vary on;gzip_disable "MSIE [1-6]\.";root /home/wwwroot/iotlinks-client/dist;
#     include /etc/nginx/mime.types;location / {index  index.html;}location ^~/upload/ {proxy_pass http://fileserver;proxy_set_header Host $host:$server_port;proxy_set_header X-Real-IP  $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}location ^~/veiplinks/file/static {proxy_pass http://fileserver/file/static;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header Host $host:$server_port;proxy_set_header X-Real-IP  $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_send_timeout      30m;proxy_read_timeout      30m;client_max_body_size    100m;}location ^~/veiplinks/ {proxy_pass http://iotserver/;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header Host $host:$server_port;proxy_set_header X-Real-IP  $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_http_version 1.1;proxy_set_header Upgrade $http_upgrade;proxy_set_header Connection "upgrade";proxy_connect_timeout   1;proxy_buffering off;chunked_transfer_encoding off;proxy_cache off;proxy_send_timeout      30m;proxy_read_timeout      30m;client_max_body_size    100m;}
}

b、在tcp目录下创建文件ngx_stream_proxy.conf并编辑

   upstream mqtt-cluster {
#        hash $remote_addr consistent;server 192.168.0.26:1889 max_fails=3 fail_timeout=10s;server 192.168.0.27:1889 max_fails=3 fail_timeout=10s;server 192.168.0.28:1889 max_fails=3 fail_timeout=10s;server 192.168.0.107:1889 max_fails=3 fail_timeout=10s;server 192.168.0.104:1889 max_fails=3 fail_timeout=10s;}upstream http-cluster {
#        hash $remote_addr consistent;server 192.168.0.26:8891 max_fails=3 fail_timeout=10s;server 192.168.0.27:8891 max_fails=3 fail_timeout=10s;server 192.168.0.28:8891 max_fails=3 fail_timeout=10s;server 192.168.0.107:8891 max_fails=3 fail_timeout=10s;server 192.168.0.104:8891 max_fails=3 fail_timeout=10s;}upstream tcp-cluster {
#        hash $remote_addr consistent;server 192.168.0.26:8893 max_fails=3 fail_timeout=10s;server 192.168.0.27:8893 max_fails=3 fail_timeout=10s;server 192.168.0.28:8893 max_fails=3 fail_timeout=10s;server 192.168.0.107:8893 max_fails=3 fail_timeout=10s;server 192.168.0.104:8893 max_fails=3 fail_timeout=10s;}upstream rs485-tcp-cluster {
#        hash $remote_addr consistent;server 192.168.0.26:8894 max_fails=3 fail_timeout=10s;server 192.168.0.27:8894 max_fails=3 fail_timeout=10s;server 192.168.0.28:8894 max_fails=3 fail_timeout=10s;server 192.168.0.107:8894 max_fails=3 fail_timeout=10s;server 192.168.0.104:8894 max_fails=3 fail_timeout=10s;}server {listen 1884;proxy_pass mqtt-cluster;proxy_connect_timeout 30s;proxy_timeout 30s;}server {listen 8841;proxy_pass http-cluster;proxy_connect_timeout 30s;proxy_timeout 30s;}server {listen 8843;proxy_pass tcp-cluster;proxy_connect_timeout 30s;proxy_timeout 30s;}server {listen 8844;proxy_pass rs485-tcp-cluster;proxy_connect_timeout 30s;proxy_timeout 30s;}

3、重启ngnix服务器，当请求来到nginx服务会被转发到不同服务器上
