[Linux] Building Amazon Linux 2 Server Part 1 (Nginx Installation)

---

---

Let's install NginX, Tomcat, Jenkins on Amazon Linux 2 server
In this part, install nginx after yum update.

After checking the initial storage space, yum update

I created an EC2 instance with 8GB of EBS storage, and I have 6.4G of storage space left with nothing installed.

$ df -h  
Filesystem      Size  Used Avail Use% Mounted on  
devtmpfs        474M     0  474M   0% /dev  
tmpfs           483M     0  483M   0% /dev/shm  
tmpfs           483M  400K  483M   1% /run

tmpfs            97M     0   97M   0% /run/user/1000  

yum update

First, update the yum package to the latest version.

sudo yum -y update  

Install nginx

Check the repo.
If a message indicating that the package list cannot be found is displayed, you must manually add the repo information.

$ yum info nginx   
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd  
Error: No matching Packages to list  

Edit the /etc/yum.repos.d/nginx.repo file to add the repo.

$ sudo vi /etc/yum.repos.d/nginx.repo  

Add the following to the yum.repos.d/nginx.repo file.

[nginx]  
name=nginx repo  
baseurl=http://nginx.org/packages/centos/7/$basearch/  
gpgcheck=0  
enabled=1  

Save the yum.repos.d/nginx.repo file and check the repo again.

$ yum info nginx
