You can clear your bash history like this:
#cat /dev/null > ~/.bash_history && history -c && exit or
#cat /dev/null > ~/.bash_history erases the content of the ~/.bash_history file.
history -c clears the current terminal history.
First, you need to log in SSH or Putty to your server
then use command passwd to change the password. below example is changed the root password for a Centos:
[root @ VM ~]# passwd (Changing password for user root.)
New password: (You should type your new password here)
Retype new password: (You should retype your new password again)
[root @ VM ~]# all authentication tokens updated successfully. (Your password change successfully)
Creating a Minecraft server is easy. Login to your new CentOS 7 1GB RAM VPS Server at Vultr and install Java 1.6.0 Open JDK.
ssh [email protected]
[root@vultr ~]# yum install java-1.6.0-openjdk
<some output here>
Is this ok [y/N]: y
Open the Minecraft server port in
firewall-cmd --zone=public --permanent --add-port=25565/tcp
Make a user run your Minecraft server under. This is for security purposes as it is not good practice to run a Minecraft server as root.
#set a secure password.
#this allows you to run screen while su'd from root for the next step
chown mcserver `tty`
Now lets change users and install Minecraft! Change the
wget URL accordingly for newer versions of Minecraft.
su - mcuser
wget -O minecraft_server.jar https://launcher.mojang.com/v1/objects/1b557e7b033b583cd9f66746b7a9ab1ec1673ced/server.jar
chmod +x minecraft_server.jar
echo "eula=true" > eula.txt
#start your Minecraft Server
java -Xmx5376M -Xms5376M -jar minecraft_server.jar nogui
Congratulations, your Minecraft server is now up and running on your high-performance SSD VPS server!
To install on a 768MB VPS follow the same commands above but change the last java command to:
java -Xmx3840M -Xms3840M -jar minecraft_server.jar nogui
If you require more players (and thus more RAM) you just launch a larger instance and then simply subtract 256M from the amount of RAM your instance has allocated. For example, a 4096 instance would launch with
#add user Type whitelist add “USERNAME”
You need to pass the following options:
rm -rf dir1
rm -rf /path/to/dir/
rm -rf /home/vivek/oldschoolpics/
rm filename OR unlink filename
