location /myalias {
root /path/to;
}
the directory name in filesystem must be same as the one specified in location (in this case /path/to/myalias)

you can't make it work if you want location /anotheralias mapped to /path/to/myalias (must be /path/to/anotheralias) but you can do

location /anotheralias {
alias /path/to/myalias;
}

But you must be careful when dealing with alias. Especially if you want to combine alias with try_files
