First, setup Entware from github RMerl ususwrt-merlin guide.
Login to router with a terminal like putty and enter the commands below.
Additional the openwrt.org wiki helps with customization of the server.
opkg install lighttpd php5-cgi lighttpd-mod-fastcgi
sed -i 's/#server.port = 81/server.port = 81/g' "/opt/etc/lighttpd/lighttpd.conf"
sed -i "/server.upload-dirs*/cserver.upload-dirs = ( \"/opt/tmp\" )" "/opt/etc/lighttpd/lighttpd.conf"
or
# nano /opt/etc/lighttpd/lighttpd.conf
and remove the commenting hash (#) prefix from the server.port line,
and change the line that starts with server.upload-dirs from /tmp to /opt/tmp.
cat >> /opt/share/www/index.html << EOF
<html>
<head>
<title>lighttpd default page</title>
</head>
<body>
<h2>lighttpd server is running.</h2>

or
# nano /opt/share/www/index.html
