Here I choose Hostwinds VPS because I have multiple uses.

3.Connect VPS via SSH & Download FileZilla

Mac OS is very simple:
$ ssh root@vpsip

Security Settings

• For security reason, change SSH port: 22 -> 3752
  
  After modification, connect command is:
  $ ssh -p portnum root@ip 
  
• Remove those two lines to enable longer login duration.

$ vi /etc/ssh/sshd_config 
$ service sshd restart (Redirect to) 
$ systemctl restart sshd.service 

• Update system
  Make sure all software/kernel are updated.
  $ yum -y update 
  

Connect VPS via FileZilla

In order to transfer files between local computer and cloud server.

4.Install LNMP on VPS

Install LNMP in one step. Detailed steps can be found here.
In this tutorial, install lnmp1.6 version. 

1. Download Installation Package

Use the following command to install.

$ wget http://soft.vpser.net/lnmp/lnmp1.6.tar.gz -cO lnmp1.6.tar.gz && tar zxf lnmp1.6.tar.gz && cd lnmp1.6 && ./install.sh lnmp

MySQL 5.5.60 (Default)

1. MySQL 5.6,5.7 and MariaDB 10 require > 1G RAM. Input your version number and press enter.
2. Enter your database password.
3. Enable InnoDB.
   
   

PHP 7.2.18 (Default is PHP 5.6.40)

Press any key to continue… Enter and wait.

Problems:
