Explanation: The root and alias
root commands in
location just set the searched root to the root setting directory, that is, the uri will not be truncated, but the original uri will be used to jump to the directory to find the file
ais command will truncate the matching uri, and then use the path set by alias to add Search the remaining uri as a subpath
location proxy_pass's uri
If the proxy_pass url does not have a uri
If the tail is "/", the matching uri will be truncated
If the tail is not "/", the matching uri will not be truncated
If the url of proxy_pass contains uri, the matching uri will be truncated
examples
root## in location
#
root@pts/1 $ ls -ld /data/web/lctest*|awk '{print $nf}' /data/web/lctest /data/web/lctest2 /data/web/lctest3 /data/web/lctest4 location /lctest { root /data/web/; } location /lctest2/ { root /data/web/; } location /lctest3 { root /data/web; } location /lctest4/ { root /data/web; }
curl test results are as follows
root@pts/1 $ curl http://tapi.xxxx.com/lctest/ hello world root@pts/1 $ curl http://tapi.xxxx.com/lctest2/ hello world 2 root@pts/1 $ curl http://tapi.xxxx.com/lctest3/ 3 hello world root@pts/1 $ curl http://tapi.xxxx.com/lctest4/ hello world 4
location alias
location /lctest5 { alias /data/web/; } location /lctest6/ { alias /data/web/; } location /lctest7 { alias /data/web; } ## 403 /data/web forbidden location /lctest8/ { alias /data/web; }
curl test results are as follows
curl 'http://tapi.kaishustory.com/lctest5/' curl 'http://tapi.kaishustory.com/lctest6/' curl 'http://tapi.kaishustory.com/lctest7/' 结果都是 /data/web/index.html的输出 root@pts/1 $ curl 'http://tapi.kaishustory.com/lctest8/' <html> <head><title>403 forbidden</title></head> <body bgcolor="white"> <center><h1>403 forbidden</h1></center> <hr><center>nginx</center> </body> </html>
