注意：实际工程应该会用docker部署。

安装nginx

sudo apt install libpcre3-dev zlib1g openssl -y
wget https://nginx.org/download/nginx-1.26.0.tar.gz
#安装到/home/gyl/workspace/mprpc/vendor/nginx-1.26.0下
tar xfzv nginx-1.26.0.tar.gz && cd nginx-1.26.0 && ./configure --with-stream --prefix=/home/gyl/workspace/mprpc/vendor/nginx-1.26.0
make && make install 
vim nginx-1.26.0/conf/nginx.conf 
追加以下内容:
stream {upstream Server1 {#后续在这里加配服务器即可增加集群server 127.0.0.1:6001 weight=1 max_fails=3 fail_timeout=30s; #weight权重(涉及负载均衡策略)，max_fails心跳次数server 127.0.0.1:6002 weight=1 max_fails=3 fail_timeout=30s;}server {proxy_connect_timeout 1s; listen 8001; #nginx监听8001端口，客户端只需要连服务器的8001端口即可。proxy_pass Server2;tcp_nodelay on;}upstream Server2 {server 127.0.0.1:6003 weight=1 max_fails=3 fail_timeout=30s; #weight权重(涉及负载均衡策略)，max_fails心跳次数server 127.0.0.1:6001 weight=1 max_fails=3 fail_timeout=30s;}server {proxy_connect_timeout 1s; listen 8000; #nginx监听8000端口，客户端只需要连服务器的8000端口即可。proxy_pass Server2;tcp_nodelay on;}
}

上面的配置使nginx监听8001和8002两个端口，访问8001会转发给6001和6002，访问8002会转发给6003和6004，至此，实现2个集群。

使用

cd nginx-1.26.0/sbin
sudo ./nginx  #启动
sudo ./nginx -s stop #停止
sudo ./nginx -s reload #修改配置后平滑重启
