failed (111: Connection refused) while connecting to upstream

nginx的主配置文件就照着下面配置,基本技能解决问题
userroot; worker_processes4; error_loglogs/error.log notice; events { worker_connections65535; } http { default_typeapplication/octet-stream; log_formatmain'$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_loglogs/access.logmain; port_in_redirectoff; sendfileon; tcp_nopushon; tcp_nodelayon; gzipon; gzip_min_length5k; gzip_buffers4 16k; gzip_http_version 1.0; gzip_comp_level 4; gzip_typestext/plain application/x-javascript application/javascripttext/cssapplication/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png; gzip_vary on; gzip_disable "MSIE [1-6]\."; keepalive_timeout65; client_body_timeout12; client_header_timeout12; send_timeout10; include conf.d/*.conf; }

  • 下面为之前出问题的nginx配置
userroot; worker_processes4; worker_rlimit_nofile 65535; error_loglogs/error.log error; events { use epoll; worker_connections65535; }http { includemime.types; default_typeapplication/octet-stream; log_format main'{"@timestamp":"$time_iso8601",' '"@source":"$server_addr",' '"hostname":"$hostname",' '"ip":"$http_x_forwarded_for",' '"client":"$remote_addr",' '"request_method":"$request_method",' '"scheme":"$scheme",' '"domain":"$server_name",' '"referer":"$http_referer",' '"request":"$request_uri",' '"args":"$args",' '"size":$body_bytes_sent,' '"status": $status,' '"responsetime":$request_time,' '"upstreamtime":"$upstream_response_time",' '"upstreamaddr":"$upstream_addr",' '"http_user_agent":"$http_user_agent",' '"https":"$https"' '}'; access_loglogs/access.logmain; sendfileon; client_max_body_size 256m; server_tokens off ; proxy_intercept_errors on; keepalive_timeout30; gzipon; gzip_min_length5k; gzip_buffers4 16k; gzip_http_version 1.0; gzip_comp_level 4; gzip_typestext/plain application/x-javascript application/javascripttext/cssapplication/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png; gzip_vary on; gzip_disable "MSIE [1-6]\."; includeconf.d/*.conf; fastcgi_intercept_errors on; }
