Compilation and Installation

Use PuTTY to log in to the server as the root user.
Go to the following directory:
```
cd /path/to/ROOT
```
Decompress the ROOT installation package and go to the installation directory.
```
tar -xzvf root_v6.20.00.source.tar.gz
cd root-6.20.00
```
Create and access the directory for compiling the ROOT software.
```
mkdir obj
cd obj
```
Ensure that the server is connected to the Internet and compile and install the software.
```
cmake ./ -DCMAKE_INSTALL_PREFIX=/path/to/ROOT -DENABLE_PERL=FALSE
make
make install
```
Add the environment variables.
```
source ../bin/thisroot.sh
```
