The post How to install Moodle with Ubuntu 20.04 LTS. appeared first on Linux Windows and android Tutorials.

Requirements:

• Fresh minimal installation of Centos 7 without any configuration changes.
• A static IP address

Step 1. Configure Hostname

Note: hostname must be differnet from your main domain.(for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname).

You can use the following command for hostname setup eg. osradar.localhost.localdomain

# hostnamectl set-hostname osradar.localhost.localdomain

# hostnamectl

Step 2. Setup Firewall

You must open following ports used by Sentora configurations in firewall so all services will run without any issue.

20 & 21 : FTP
22 SSH
25 (TCP) : SMTP
53 (TCP & UDP) : DNS
80 (TCP & UDP) : HTTP
110 : POP3
143 : IMAP
443 : HTTPS
3306: MySQL

Use below command to add ports in firewall and reload it to apply new changes.

# firewall-cmd --zone=public --permanent --add-port={20/tcp,21/tcp,22/tcp,25/tcp,53/tcp,80/tcp,110/tcp,143/tcp,443/tcp,3306/tcp}

# firewall-cmd --reload

Step 3. Installing Sentora

First install wget package using below command

# yum install wget -y

Now download installer and make it executable using below commands

# cd

# wget http://sentora.org/install

# chmod +x install

Start Sentora installation using below command

# ./install

During the installation process you will be asked to choose your geographical area and the time zone. So choose you location, set your time zone and press “Enter” to continue. In my case I will use Asia.

In the next step you will be asked to configure sub-domain, which will be used to access Sentora Panel, Secondly set the public IP of the server.

Here you might get the warning about your DNS configurations if its not properly configured then add records in your DNS manager.

Press “Y” to accept and install Senotra on your choosed subdomain with given IP. Installation can take more than 30 minutes depending on your inernet connection, because it needs to install and activate all required packages for the server.

Once the installation completeion, you will be greeted with sentora login details, copy all login details before restart (A file of login details also placed in /root/passwords.txt). Now press “Y” and ENTER key to restart the server.

Step 4. Login Sentora Control Panel.

Once server boots up, open your web browser and access your Sentora Control panel using the sub-domain or your server’s IP address and type your credentials to login.

OR

Congratulations! you have successfully installed the latest version of Sentora on CentOS 7 server. Now you can manage your multiple domains web hosting free of cost on your own hosting server.

Step: 1 Install Samba Server

Use below command to install samba with necessary packages.

# yum install samba samba-common samba-client -y

Step 2: Check Windows Workgroup

Before samba configurations, make sure Windows machine is in same workgroup.
open the cmd prompt in Windows machine and run the following command.

> net config workstation

Step 3: Samba Configuration

before configuration rename samba default configuration file /etc/samba/smb.conf as backup using below command.

# mv /etc/samba/smb.conf /etc/samba/smb.conf.default

Samba Anonymous File Sharing

Now create a shared folder on the server where all files/folders will be stored and set appropriate permissions on it and allow selinux for the samba configuration.

Run below commands

# mkdir -p /srv/samba/anonymous

# chmod -R 0755 /srv/samba/anonymous

# chown -R nobody:nobody /srv/samba/anonymous

# chcon -t samba_share_t /srv/samba/anonymous

Now make following changes in new samba configuration file.

# vi /etc/samba/smb.conf

[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = centos
security = user
map to guest = bad user
dns proxy = no

[Anonymous]
path = /srv/samba/anonymous
browsable =yes
writable = yes
guest ok = yes
read only = no

Run below commant to verify samba configurations

# testparm

Step 4: Start and Add Samba Services in firewall

The PHP 7 branch is part of an attempt by developers to improve the syntax of the language in order to allow programmers to write better code and create better web applications.

Another aspect to bear in mind is that PHP 7 represents a substantial improvement in security with previous versions.

In summary, these are some of its novelties:

• The improved core of Zend Engine 3.0, a runtime engine that interprets PHP, is now faster and more efficient, which makes PHP 7 much better performing.
• PHP 7 removed obsolete functions in order to make it smaller and lighter.
• Now you can declare up to 4 types of primitive data, int, string, float and boolean.

In others words, if you are a web developer or you are starting in the world of web management or if on the contrary, you manage a CMS, you must install PHP 7.

1. Upgrade CentOS 7

In the first place, you must update the system. It’s always a good idea to do so, because it ensures we have the latest security patches for the system. Open a terminal and type:

:~$ su

After entering the password you will be root user.

Next, you must run yum to update the system in question.

:~# yum update

When the installation is finished, you will have an updated system ready for PHP7.

2. Add an external repository

As I mentioned earlier, CentOS 7 comes in its repositories with PHP 5.6. That’s why you need an external repository for PHP7.

Remi is a repository for CentOS 7, RHEL and Fedora that contains updated RPM packages such as PHP. It is highly reliable and very popular with the Linux distribution community. Today you will use this repository to install PHP 7. Run:

:~# yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Then to enable the use of the repository, type:

:~# yum-config-manager --enable remi-php72

3. Install PHP

PHP is a vital component of the LAMP stack. Now proceed to install the most common PHP packages. Of course these will depend on the applications you need to run. I will only show the most used ones.

:~$ yum install php php-common php-opcache php-cli php-xml php-gd php-curl php-mcrypt php-zip php-imap

When installation is complete, you can check which version has been installed. Run:

:~# php -v

4. Configure PHP to work with apache and Nginx

In fact, PHP 7 doesn’t need extra configurations to work with apache. You just have to restart the service and that’s enough.

:~# systemctl restart httpd

In the case of Ngnix, if you have to install the php-fpm package.

.~# yum install php-fpm

Just install a web server and try your new PHP 7.

And this is it.

As you could see, the installation is quite simple but very useful when working with web applications. Updating PHP is a good way to keep the server in top condition.

Tell us, PHP programs? have you noticed a big performance difference? Did you use this tutorial?
