How to Setup VsFTPD Service with SSL/TLS on Linux CentOS 7 / RHEL 7 / Oracle Linux 7

Setup VsFTPD service

If you have your own dedicated server or virtual private server (VPS) that run in linux operating system to host your website or blog, it is recommended to install and setup ftp Service in order to facilitate the transfer of files and update your website. Among the well-known FTP software is VsFTPD.

VsFTPD means “Very Secure FTP Daemon” is the free FTP for Linux and UNIX operating systems, which are very stable, fast and safe to use even if the server is in the internet.

Is ftp secure ?

Any server in the internet is vulnerable to intruders that may spying on data transfer and steal confidential information such as id and password if encryption is not configured.

In this article, I will share the basic steps to setup VsFTPD service with SSL/TLS encryption on CentOS 7, RHEL 7 and Oracle Linux 7 operating system.

Steps to Setup VsFTPD Service with SSL/TLS

1. Install and setup VsFTPD Service :

# yum install vsftpd -y

2. Add ftp user :

# useradd user1
# passwd user1
Changing password for user user1.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

3. Now Edit VsFTPd configuration file /etc/vsftpd/vsftpd.conf :

Enable the following :

# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
# Uncomment this to allow local users to log in.
# When SELinux is enforcing check for SE bool ftp_home_dir
# Uncomment this to enable any form of FTP write command.

Optionaly. you can customize the banner :

# You may fully customise the login banner string:
ftpd_banner=Welcome to ehowstuff FTP service.

4. Create ssl and private directory :

# mkdir -p /etc/vsftpd/ssl
# mkdir -p /etc/vsftpd/ssl/private/

5. Create a SSL certificate using on of following command :

# openssl req -x509 -nodes -days 720 -newkey rsa:2048 -keyout /etc/vsftpd/ssl/private/vsftpd.key -out /etc/vsftpd/ssl/vsftpd.pem

You will be prompted with a series of question, which you answer as they appear :

Example :

# openssl req -x509 -nodes -days 720 -newkey rsa:2048 -keyout /etc/vsftpd/ssl/private/vsftpd.key -out /etc/vsftpd/ssl/vsftpd.pem
Generating a 2048 bit RSA private key
writing new private key to '/etc/vsftpd/ssl/private/vsftpd.key'
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
Country Name (2 letter code) [XX]:MY
State or Province Name (full name) []:Malaysia
Locality Name (eg, city) [Default City]:Kuala Lumpur
Organization Name (eg, company) [Default Company Ltd]:ehowstuff
Organizational Unit Name (eg, section) []:IT
Common Name (eg, your name or your server's hostname) []:centos7
Email Address []:admin@ehowstuff.local

6. Assign the permission :

# chmod 400 /etc/vsftpd/ssl/vsftpd.pem
# chmod 400 /etc/vsftpd/ssl/private/vsftpd.key

7. Edit vsftpd configuration file /etc/vsftpd/vsftpd.conf. Specify the location of our certificate and key files then add the following line at the bottom of vsftpd.conf :

# Add follows to the bottom


8. Stop and Start VsFTPD Service and make it auto start at boot :

# systemctl stop vsftpd
# systemctl start vsftpd
# systemctl enable vsftpd

9. Check VsFTPD status :

# systemctl status vsftpd
vsftpd.service - Vsftpd ftp daemon
   Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; enabled)
   Active: active (running) since Sat 2014-12-13 10:31:30 MYT; 34s ago
  Process: 20864 ExecStart=/usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf (code=exited, status=0/SUCCESS)
 Main PID: 20865 (vsftpd)
   CGroup: /system.slice/vsftpd.service
           ââ20865 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf

Securing and Hardening Linux Dedicated Server

securing linuxWhen we hosted the linux dedicated server or virtual private server(VPS) in a data center, security of the system is very important in order to ensure the data and the information are safe from the hackers. Securing and hardening linux dedicated server is mandatory when nearly every computing resources and the application systems is online and susceptible to attack. This post share basic security and hardening tips for the linux dedicated server. If you are plan to host your own linux dedicated server, then this post should able to provide you a good baseline and ideas. The following are the best practices to securing and hardening linux dedicated server :

1. Patching Linux Systems
2. Keep Linux Kernel and Software such as WordPress/Joomla Up to Date
3. Secure SSH
4. Enforcing Stronger Passwords and Password Aging
5. Disable Unnecessary Processes, Services and Daemons

9 Steps to Setup Dedicated Server for your Website

dedicated serverThere are different types of hosting services are used in the computer technology such as shared hosting, VPS (Virtual Private Server) and Dedicated Server hosting. For new websites with low numbers of visitors, I would highly recommend getting a shared hosting. If you need more control of the server, then you should moving from shared hosting to a VPS. There are plenty of hosting companies offering Virtual Private Servers, and VPS hosting is getting cheaper. This blog hosted at RamNode VPS.

At some point, your site will get super slow server performance impact on limited resources when running VPS hosting. More server resources required is due to the increased number of visitors to the tens of thousands or hundreds of thousands per day.

At the situation when you are hitting super slow website performance due to huge numbers of traffic, I would recommend you to getting dedicated servers. Cheaper way is to setup VPS additional to balance the load. If cost is not an issue, I always recommend you to purchase a dedicated server as this will give you excellent processing performance. In a dedicated server environment , resources such as memory , hard drive storage capacity, processing power, and network access are all 100% to dedicated servers instead of shared with multiple VPS or dozens of shared hosting customers. Popular websites on the Internet certainly have excellent servers behind them. Without such an excellent server, web sites with high concurrency of visitors will not be able to survive.

If you are an experienced system administrator, the following articles may not attract you, but for web developers and those new to the web hosting, the following article can be a useful guide on their first steps. I believe the popular website on the internet has been setup by a consultant who specializes in servers or installed by an experienced system administrator. In this article, I would like to share 9 steps to setup Dedicated Server for your Website.

Once you have purchased a dedicated server, you can log in to your server to complete the setup of your server from start to finish. Below is a guide and checklist for you who are new to server administration.

9 Steps to Setup Dedicated Server

1. Choose and Install Linux operating system :

Choosing the right platform on which to host your dedicated server. Please make sure that you are familiar with the preferred operating system (OS) either CentOS or Fedora or Ubuntu or maybe Windows OS. If you choose linux OS, I would recommend you to do a clean minimal installed of the OS.

2. Update operating system :

Make sure that the OS has been applied the latest patches.

3. Install Apache or Nginx Web server :

Apache httpd is one of the most popular web servers and has a lot of features that make it very extensible and useful for many different types of websites. As an alternative to Apache http server, you also can install NGINX. Nginx or “engine x” is a free, open-source HTTP server that provide high-performance edge web server with the lowest memory footprint and the key features to build modern and efficient web infrastructure. I used Nginx to run this blog.

4. Install MySQL Database server :

MySQL server is a database server that can stores and retrieves data for the blog, websites and applications. It is one of the most popular most used in the internet especially for content management and blogging site.

5. Install PHP :

PHP: Hypertext Preprocessor is a widely used, free and open-source server-side scripting language that was especially designed for web development to produce dynamic web pages and can be embedded into HTML.

6. Install Bind DNS server :

BIND (the Berkeley Internet Name Domain) also known as NAMED is the most widely used DNS server in the internet. Bind DNS helps to resolve domain name to ip address and ip address to domain name.

7. Install FTP server :

File Transfer Protocol (FTP) is a network protocol used transfer file in the network. one of the most popular FTP server for Unix/Linux is vsftpd. Vsftpd stand for Very Secure FTP Daemon. Vsftpd not only just another popular FTP server for Unix/Linux systems, but vsftpd delivers excellent performance by consuming less memory.

8. Harden and Secure the dedicated server :

There are a few steps to harden the OS of dedicated server.
a) Install a host based firewall to protect your dedicated server from unauthorized access:
Once you have your web server running, you have to install host based firewall and open only certain port in your firewall. I would recommend you tosetting up iptables on your linux dedicated server.

b) Use Strong passwords :
Password complexity requirements should be in place to enforce strong password. A strong password should have mixed case, special characters, numbers, and be longer than 8 characters. Additional security, the passwords should be changed regularly.

c) Disable Unnecessary Processes, Services and Daemons :
I would recommend you to disable unneeded processes,services and daemon such as bluetooth, hidd, cups, yum-updatesd, ypbind, nfs, snmpd, saslauthd, netfs, gpm, pcmcia and sendmail. SELinux also should be set to “Disabled”. This is still very experimental so I would leave this disabled unless you really know what you are doing.

9. Install or migrate over the content of your website or blog :

You can start to migrate over the content of your website or blog to your new dedicated server. For dynamic content blog, i would recommend you to use WordPress as a platform. WordPress is an open-source blogging platform. It’s a free blogging tool and content management system (CMS) based on PHP and MySQL.

I hope that this 9 steps to setup dedicated server can be a useful guide on your first steps to have your own dedicated server to run a websites.
