Nginx configuration file

The code is as follows

Copy Code

server { Listen 80; server_name 192.168.1.199; Root/usr/local/nginx5/html/test; Index index.html index.htm index.php; location/image/{ Set $image _root/usr/local/nginx5/html/test; Set $file $image _root$uri; Set $forward _url ""; if (!-e $file) { Rewrite_by_lua ' Local Originaluri = nil; Local area = nil; Local index = String.find (Ngx.var.uri, "([0-9]+) x ([0-9]+)"); Local Ouindex = nil; Local fileextname = nil; Local filesuffix = nil; If index ~= nil then Originaluri = string.sub (Ngx.var.uri, 0, index-2); Ouindex = String.find (Originaluri, "([.])"); Fileextname = String.sub (originaluri,ouindex+1); Filesuffix = String.sub (originaluri,0,ouindex-1); Area = String.sub (Ngx.var.uri, index); index = string.find (area, "([.])"); If index ~= nil then Area = string.sub (area, 0, index-1); End End If Originaluri ~= Nil Then Local command = "/usr/local/gm/bin/gm convert". Ngx.var.image_root.. Originaluri.. "-thumbnail". Area.. "-background gray-gravity center-extent". Area.. " ".. Ngx.var.image_root.. Originaluri ... " _" .. Area.. ".".. Fileextname; Os.execute ("Echo command" ... command ...) >>/usr/local/nginx5/html/123.txt ");                                  os.execute (command);                                  Ngx.var.forward_url = Filesuffix ... " _thumb. " Fileextname; Else Ngx.var.forward_url = Ngx.var.uri; End '; } } }

The above configuration is simply to generate a thumbnail configuration, through the Nginx to control LUA can also achieve only a fixed size of the picture or, can also call a folder of pictures generated into the B folder and other very useful features
