# Linux Core Installation
| Installation Guide | |
| :- | :- |
| This article is a part of the Installation Guide. You can read it alone or click on the previous link to easily move between the steps. |
| [<< Step 1: Requirements](requirements.md) | [Step 3: Server Setup >>](server-setup.md) |
## Required software
See [Requirements](requirements.md) before you continue.
## Getting the source code
Choose **ONE** of the following method, run one of the below `git ...` commands in your terminal.
1. Clone only the master branch + full history (smaller size - recommended):
```sh
git clone https://github.com/azerothcore/azerothcore-wotlk.git --branch master --single-branch azerothcore
```
1. Clone only the master branch + no previous history (smallest size):
```sh
git clone https://github.com/azerothcore/azerothcore-wotlk.git --branch master --single-branch azerothcore --depth 1
```
Note: If you want to get the full history back, use `git fetch --unshallow`.
1. Clone all branches and all history:
```sh
git clone https://github.com/azerothcore/azerothcore-wotlk.git azerothcore
```
This will create an `azerothcore-wotlk` directory containing the AC source files.
## Compiling the source code
### Creating the build-directory
To avoid issues with updates and colliding source builds, we create a specific build-directory, so we avoid any possible issues due to that (if any might occur)
```sh
cd azerothcore
mkdir build
cd build
```
### Configuring for compiling
Before running the CMake command, replace `$HOME/azeroth-server/` with the path of the server installation (where you want to place the compiled binaries).
Parameter explanation for advanced users [CMake options](cmake-options.md).
At this point, you must be in your "build/" directory.
**Note**: in the following command the variable `$HOME` is the path of the **current user**, so if you are logged as root, $HOME will be "/root". You can check the state of the environment variable, as follows:
```sh
echo $HOME
```
**Note**: in case you use a non-default package for `clang`, you need to replace it accordingly. For example, if you installed `clang-6.0` then you have to replace `clang` with `clang-6.0` and `clang++` with `clang++-6.0`
```sh
cmake ../ -DCMAKE_INSTALL_PREFIX=$HOME/azeroth-server/ -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DWITH_WARNINGS=1 -DTOOLS_BUILD=all -DSCRIPTS=static -DMODULES=static
```
To know the amount of cores available.
You can use the following command
```sh
nproc --all
```
Then, replacing `6` with the number of threads that you want to execute, type:
```sh
make -j 6
make install
```
