Gamerules allow changing specific things on servers like the day/night cycle, creepers exploding, mobs dropping items when they die, or even keeping a player's inventory upon death.
Preparation
The first step to using Gamerules is to make sure your account has been made a server operator.
Next, log into your Minecraft server.

FAQ
Can I switch off creepers exploding in Minecraft?
Yes, you sure can! You can control this feature by using gamerules in Minecraft. You would need to use mobGriefing gamerule to toggle creepers exploding.
How can I keep my stuff when I die?
No more crying over lost items! The keepInventory gamerule lets you keep your things safe even when you die in your Minecraft game.
Do Minecraft mobs drop items when they die?
Definitely, but only if you want them to! The doMobLoot gamerule decides whether mobs drop items when they die.
What's this about Minecraft's day-night cycle?
The Minecraft world can be made to mimic the real world! The doDaylightCycle gamerule helps you control the day-night cycle and moon phases in your game.
Can I stop mobs from spawning in Minecraft?
Absolutely you can! If mobs are ruining your peaceful gameplay, use the doMobSpawning gamerule to put a stop to it.
Can I make Minecraft weather constant?
Yes, indeed! The doWeatherCycle gamerule allows you to control whether the weather in your Minecraft world will change or remain constant.
How to control damage in Minecraft?
You've got some choices to figure out such as falling or catching fire using drowningDamage, fallDamage and fireDamage gamerules respectively.
Can you spawn in a particular radius in the game?
That's possible! A player can spawn in a given radius out from the world spawn coordinates when they first enter the game or when they die without a spawn point with the spawnRadius gamerule.
Can you stop the fire spread in Minecraft?
Oh yes, you can! The doFireTick is another exciting gamerule. It's your magic wand! Do you want fire to spread within your game? Or maybe you want it to go out on its own, naturally? The power is in your hands
Can the player regenerate health in Minecraft?
Of course! The naturalRegeneration gamerule is what you need to use if you'd like the player to regenerate health naturally. Still, there are some things these gamerules won't change. I'm talking about external healing. Do you remember golden apples? Or the Regeneration effect? They still work as normal.
