Compiling Software from Source in SUSE Linux Enterprise

In this hands-on lab, we will be compiling software from source code and then deploying and testing that software.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install the GNU Compiler, Retrieve the Nginx Source Files Package, and Extract It

Install the GNU compiler:
```
sudo -i zypper in -y gcc
```

From your home directory, download the Nginx package:

wget https://nginx.org/download/nginx-1.16.1.tar.gz

Extract the package, and switch to its directory:
```
tar zxf nginx-1.16.1.tar.gz
cd nginx-1.16.1
```

Once Inside the Package Directory, Configure the Make File, and Run the Compile and Install Commands

Run the configure command and read the output:
```
./configure
```
Correct the issue using the --without directive:
```
./configure --without-http_rewrite_module
```

Continue until your configure runs with no issues:

./configure --without-http_rewrite_module --without-http_gzip_module

Once this has completed, run the compile and install commands:
```
make

sudo make install
```

Run Nginx and Ensure It Loads, and Then Stop Nginx

Start Nginx:
```
sudo /usr/local/nginx/sbin/nginx
```
Make sure it is working by loading the index page:
```
curl 127.0.0.1
```
Locate the master process ID:
```
ps -ax | grep nginx
```
Copy the ID of the master process.
Stop Nginx:
```
sudo kill <MASTER_PROCESS_ID>
```
Verify Nginx is not running:
```
ps -ax | grep nginx
```
It should return only the grep command.

Create a `websrv` Directory, Reconfigure Nginx to Install to That Directory, and Make and Install It to the `websrv` Directory

Ensure you are in the Nginx source directory:
```
cd ~/nginx-1.16.1
```
Clean up the make environment:
```
make clean
```

Configure the makefile:

./configure --prefix=/home/cloud_user/websrv --without-http_rewrite_module --without-http_gzip_module

Make the software and install it:
```
make
sudo make install
```

Run and Verify That Nginx Is Working from the `websrv` Directory

Start the Nginx you just installed:
```
cd ~/websrv/sbin
sudo ./nginx
```
Verify it is working:
```
curl 127.0.0.1
```
Locate the master process ID:
```
ps -ax | grep nginx
```
Stop the process:
```
sudo kill <MASTER_PROCESS_ID>
```
