How to save TCP server config in esp8266, so that it is retained on reboot?

then 

AT+CIPSERVER=1,8888

That works as well as when esp8266 is turn on but when I disconnect power and then turn on settings are lost and when I use 

AT+CIPMUX?

that returns

CIPMUX:0

Please help me!

On a power reset or restart, CMUX and CIPSERVER must be applied again. You can use the following reset procedure:

// close active connection
AT+CIPCLOSE=id
// stop server
AT+CIPSERVER=0
// restart
AT+RST
// enable multiple connections (required for server mode)
AT+CIPMUX=1
// start listening
AT+CIPSERVER=1,8888
