Hi all.. I thought that I would share my working config after following the The NGINX Catchall for ISPconfig 3 howto. I have 7 sites running, 2 drupal, 2 workpress and 3 custom php. This is running on a openvz vps with 16gb and 8 cpus. You should adjust your install accordingly. I sourced most of this info from the nginx forums.. It will pass thru all vhosts created within ispconfig with no impact. But, if you manually create vhost files for each site, nginx will serve the static files directly, greatly improving the speed of your sites. Apache is configured with 2048 max clients but with this config, barely uses 100. Yet nginx was running 4000 connections recently. I have replaced the configs suggested in the howto with: nginx.conf - main conf file ** needed the worker_rlimit_nofile to eliminate open file errors, default is 1024 Code: user www-data; worker_processes 3; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; worker_rlimit_nofile 4096; events { worker_connections 2048; use epoll; } http { index index.php index.html index.htm; root /var/www/; error_page 502 503 504 /50x.html; server_names_hash_max_size 512; server_names_hash_bucket_size 128; include /etc/nginx/mime.types; default_type application/octet-stream; client_header_timeout 10m; client_body_timeout 10m; send_timeout 10m; connection_pool_size 512; client_header_buffer_size 1k; large_client_header_buffers 4 2k; request_pool_size 4k; client_body_temp_path /var/lib/nginx/body 1 2; gzip on; gzip_http_version 1.0; gzip_min_length 1100; gzip_types text/plain text/css image/x-icon application/x-javascript application/javascript text/javascript application/atom+xml application/xml; gzip_buffers 16 8k; gzip_vary on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_proxied any; gzip_comp_level 2; output_buffers 1 32k; postpone_output 1460; sendfile on; #tcp_nopush on; keepalive_timeout 75 20; tcp_nodelay off; ignore_invalid_headers on; server_tokens off; access_log off; error_log /var/log/nginx/error_log; #default nginx virtual host server #it's used if there is no other matching nginx virtual host found server { listen 80 default; #you can access nginx internal stats using lynx or alike console based web browser #at http://your.external.interface.ip/nginx_status address location /nginx_status { stub_status on; access_log off; allow 127.0.0.1; deny all; } #default proxy settings for each virtual host include /etc/nginx/proxy.conf; } include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } proxy.conf - common proxy conf file. ** set the client_max_body_size to match apache max_file_size Code: location / { proxy_pass http://127.0.0.1:82/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 64m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } proxy_failback.conf - if nginx cannot serve the file, pass it on to apache. Code: #proxy options can't be set inside if directive proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; if (!-f $request_filename) { break; proxy_pass http://127.0.0.1:82; } If you want nginx to serve static files directly, you need to add the following for each vhost in the sites-available folder, linked to the sites-enabled folder ** PNG is removed due to a realtime file issue, I hope to resolve this properly. Code: server { # listen 80; server_name www.domain.com domain.com; #default proxy settings shared are among all virtual hosts access_log off; include /etc/nginx/proxy.conf; location ~* ^.+.(jpe?g|gif|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|html?|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3)$ { #forcing browser to cache locally static content for 1 day expires 1d; root /var/www/domain.com/web/; #access_log /var/log/ispconfig/httpd/domain.com/access.log; access_log off; #graceful fallback in case if static content doesn't exist include /etc/nginx/proxy_fallback.conf; } } Good luck, I hope you find this helpful.

Found a typo in the nginx.conf file Change the line as follows error_log /var/log/nginx/error.log; Otherwise your error log will never be rotated and could get VERY large! Rob
Error 400 Bad Request I was getting this on some browsers and only on one site.. Quite strange but searching google came up with the following fix that works, something to due with cookie size. Change the line in Nginx.conf as follows large_client_header_buffers 4 2k increase the second number to 8k large_client_header_buffers 4 8k regards, Rob
Hi, I have few notes to your config files, specifically proxy.conf file. Directives: client_max_body_size and client_body_buffer_size have to be out of the location, directly in server section. proxy_connect_timeout cannot be more than 75s - look on reference http://wiki.nginx.org/HttpProxyModule#proxy_connect_timeout proxy_send_timeout set to match php max_input_type proxy_read_timeout set to match php max_execution_time I changed buffers too, because I got this error: Code: upstream sent too big header while reading response header from upstream File should look like this: Code: client_max_body_size 64m; client_body_buffer_size 128k; location / { proxy_pass http://127.0.0.1:82/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 60; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 32k; proxy_buffers 8 16k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; }
