2、修改nginx/conf/nginx.conf文件，支持负载均衡

worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; #tomcat服务 upstream test{ server localhost:8080 weight=1; server localhost:8081 weight=1; } server { listen 80; server_name localhost; location / { proxy_pass http://test; #添加如下3个配置后，当一台server宕机,切换速度会很快，此时配置是1秒 proxy_connect_timeout 1; proxy_send_timeout 1; proxy_read_timeout 1; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }
