However, I have never experienced that. What it always comes down to for me is the wrong blasted version of Java. OpenJDK 11 aka java-11-openjdk-amd64 aka Fake Java hates minecraft. After upgrading to Linux Mint 19.2 minecraft refused to run. To fix the problem it was necessary to install OpenJDK 8 aka java-8-openjdk-amd64 aka less crappy fake java. This assumes the "alternatives" system is working properly, which might not be the case, depending on how Java has been "messed up" in the past. To check this, run:Another way it was solved successfully was to install real Java... from Oracle. However the folks over at Oracle are butts and make you jump though a heap of registration hoops before they let you download their precious Oracle Java.

You will have to do some digging in logs if the Java version was not the culprit of the problem for you.

You can execute commands that control the serer and players. SERVER MODS: You can inject Forge mod loader into the Minecraft server. Within the folder, run the "forge.*.universal.jar" file. You need to accept the EULA. Open up the freshly created EULA.txt and edit the false to true. Remember, vanilla clients can’t join modded servers. Join a matching version number installation of Minecraft with Forge installed, but without any mods loaded, which will mirror the state of the server. Everyone that joins your server will need to have those mods installed; the /mod/ folder of the client and the/mod/ folder of the server should be mirrors of each other. === upgrade minecraft server to latest version ===first make a backup of minecraft server. tar -sp -zcvf minecraft1-8-8.tgz /usr/local/minecraftWe are going to upgrade from 1.8.8 to 1.12.2.

Most types of blocks can become powered. If you push a button, two blocks become powered: the block containing the button, and the block the button is attached to. The button is the power source. A lever or pressure plate is a power source. A block of redstone is always powered, it is a constant power source. A button is a momentary power source. In general, opaque blocks can be powered by redstone while any transparent blocks and non-solid blocks can't. Consider three basic Minecraft power sources:# lever# button# redstone torchWith a daylight sensor, you can create a circuit that opens your door during the day, and it closes at night. This automatic daylight door would keep mobs out at night. There are several items that can provide an input charge into redstone. These are levers, pressure plates, redstone torches, redstone blocks, buttons, detector rails, tripwire hooks and daylight sensors.Transmit power with redstone wire. Place redstone dust on the floor to make a "wire trace" on the surface of the ground, much like a printed circuit board. Redstone wire becomes powered when it is adjacent to a powered block. Redstone power runs along the redstone wire, powering the blocks underneath the wire, or near it at certain aspects. Power will travel 15 blocks from a redstone torch through redstone wire to a block. Most power components provide power level 15, but a few provide a variable amount of power. Redstone dust transmits power to adjacent redstone dust, but its strength decreases by 1 for each block of redstone dust traveled. A repeater block will be required to transmit power further away. This is similar to DC power. A repeater block can also add a preset delay of up to 4ms.

This block cannot be crafted and only server administrators are allowed to place them.Command blocks can only be obtained when cheats are activated, and can only be used in creative mode, preventing survival players in a server from accessing "staff" abilities. Command blocks are invincible outside of creative mode.

This tool works for registered online players.The UUID (Universally Unique Identifier) replaces your Minecraft username to verify your identity.I think that /home/username/.minecraft/launcher_profiles.json is the file that needs modified by injecting the UUID string to restore access to the player profile. The player profile itself is on the server. Here we need to point it that-a-way.Offline Mode: Offline UUID and usernames are stored in* minecraft/usercache.jsonEach players profile is stored as a file named by the UUID with the .dat extension located in* minecraft/world/playerdataReplace "world" with the name of your world. The playerdata files DO NOT contain the username. If you are trying to determine which offline server player the file belongs to, knowing only the UUID, you will need to reference usercache.jsonYou can delete usercache.json without consequences to your world.If an op player gets a custom head another user created, even though the owner of the head has never joined your world an entry will be created in the usercache.json file.Usernames of a different case, such as Nicole and nicole will generate different UUID player files. Usernames are case sensitive.=== system migration === cp -adv /home/nicolep/.minecraft /mnt/xxx cp /home/nicolep/Desktop/Terramining_Launcher_v9.2.jar /mnt/xxx== Online Resources ==* [http://www.minecraftmods.com/version/1-8/ Minecraft 1.8 Mods] These require [http://files.minecraftforge.net/ Minecraft Forge]* [http://terraminingmc.com/ TerraminingMC: Cracked Minecraft Launcher]* [http://journeymap.info/Home JourneyMap] Also requires [http://files.minecraftforge.net/ Minecraft Forge][[Category:PC Gaming]]
