If firewalld package is not available then you can install it with command:

# yum -y install firewalld

And start firewalld service with command:

# systemctl start firewalld

Now reload firewall configuration file by typing:

# firewall-cmd –reload

Now verify your installation of Nginx by visiting the following URL on any browser you like with http://ip_address

7. Configure Nginx File

An Nginx server configuration file plays an important role, So you should be more careful when setting up this file.

For configuring Nginx file go inside the following path with the following command:# cd /etc/nginx/conf.d

# vi default.conf

And write the following code in the above file i.e. default.conf.

Also change your domain in place of ip_address

server {

listen 80;

server_name 54.161.140.2;

root /usr/share/nginx/html/wordpress;

index index.php index.html index.htm;

location / {

try_files $uri $uri/ =404;

}

error_page 404 /404.html;

location = /40x.html {

root /usr/share/nginx/html/wordpress;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root /usr/share/nginx/html/wordpress;

}

location ~* \.php$ {

try_files $uri =404;

fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;

fastcgi_index index.php;

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

}

}

And save it with :wq command, after that edit the configuration file of php-fpm with the following command:

# vi /etc/php-fpm.d/www.conf

Open the file with above command and edit the following lines i.e.

user = nginx

group = nginx

Add new listen under listen = 127.0.0.1:9000

listen = /var/run/php-fpm/php-fpm.sock

And also add

listen.owner = nginx

listen.group = nginx

Remove comment (;) from the above two lines and save it with :wq.

8. Install WordPress File

You can easily download WordPress archive file from the link I provided in this blog.
First go inside /tmp directory by typing below command:

1. Prerequisites


Before you start the installation of WordPress with (LEMP) stack on Centos 7 VPS, you must have one Centos 7 VPS with root privileges on it or you can use sudo for non-root user.  

 You should also run basis command on server to check the following things-:

# df -h (To check the disk space on the system.)

 

# cat /etc/os-release (To verify the version of the VPS.)

 

# yum -y update (To update all the packages of the VPS)

2. Install MySQL 8.0

WordPress uses a MySQL database for storage, MySQL is used in stack for storing user details in database.

For installing MySQL on Centos 7 first you need to enable MySQL repository and then you can install MySQL.

# yum localinstall    -y https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm

The command used for installing MySQL in CentOS 7 VPS is as follows:

# yum install mysql-server -y

Then check the MySQL version by typing following command:

# mysql -V(‘V’ is in uppercase)

After the installation is completed MySQL will start automatically and you can check it’s status by typing:

# systemctl status mysqld

If MySQL is not start automatically you can write the following command:

# systemctl start mysqld

Before going for the next step you should generate a temporary password to access MySQL root user with the following command:

# grep ‘temporary password’ /var/log/mysqld.log
Now configure the MySQL secure installation to improve the security by typing the following commands.
#
mysql_secure_installation

Login with the temporary password and assign new password, after that in this configuration it ask several questions you can give Y or N according to your requirement.

Change the password for root ? N

Remove anonymous users? Y

Disallow root login remotely? Y

Remove test database and access to it? Y

                  Reload privilege tables now? Y

 

3. Configure Database in MySQL

Now create database for WordPress in MySQL for that first login with MySQL server by using the following command:

# mysql -u root -p

And give its password, after that create database in it with the command:
mysql> CREATE DATABASE wordpress;

You can also check that database is created or not with the command:

mysql> SHOW  DATABASES;

Now create user and assign him password by using command:

mysql> CREATE USER ‘wordpress’@’localhost’ IDENTIFIED 

BY ‘Password’;

After that grant all privileges to the user created under that database with the command:

mysql> GRANT ALL ON  wordpress.* TO ‘wordpress’@’localhost’;       

Then flush all privileges on MySQL server with the command:

mysql> FLUSH PRIVILEGES;

Now exit from the MySQL server you can use commands:

mysql> exit;

mysql> \q;

Note-: In MySQL you must end each command with a semicolon(;).

4. Install & Configure PHP 7.2

PHP is used by WordPress to do various functions done by PHP like calling plugin, calling theme, validating user permissions, checking option, grab from database, etc.

In this Blog we are using PHP 7.2 versionand install it with epel-release with remi repository.

Firstly, install yum-utils packages using the following command:

    # yum -y install yum-utils

After that, install epel-release package by using command:

# yum -y install epel-release

Then import remi repository from the command:

# yum -y install  http://rpms.remirepo.net/enterprise/

remi-release-7.rpm

Enable the remi repository by typing:
# yum-config-manager –enable remi-php72

After that install PHP and all required modules by using command:

# yum -y install php-fpm php-mysql php-mbstring php-xml      php-gd php-cli php-json php-opcache php-curl
Now after the installation completed you can check the PHP version with the command:
# php -v (‘v’ is in smallcase)

How to install and configure Linux Malware Detect (LMD) on Centos Web Panel(CWP) 7 with alert?

Linux Malware Detect(LMD) is a malware detector and scanner for Linux, designed for shared hosting environments. LMD is released under GNU GPLV2 license, it can be installed on cPanel, WHM and Linux environments with together other detection tools such as ClamAV. 

CWP doesn’t provide LMD service in it’s free version, it asks to take CWP pro for LMD service. You can install it from the terminal and scan for malware present in your server.

Prerequisite

CWP

Terminal access

Root user (If not use sudo)

ClamAV

Install Linux Malware Detect (LMD)

Linux Malware Detect is not available in CentOS or Epel repository, you need to install it manually from source, by using the following command:

First go inside tmp directory,

# cd /tmp

Now download and extract it from the source with the help of wget command:

# wget http://www.rfxn.com/downloads/maldetect-current.tar.gz

# tar -xzvf maldetect-current.tar.gz

After downloaded go inside the maldetect directory and run the install script with the following command:

# cd maldetect-*

# ./install.sh

Now make a symlink of the maldet command in the /bin/maldet

# ln -s /usr/local/maldetect/maldet /bin/maldet

# hash -r

Configure Linux Malware Detect (LMD)

LMD has been installed into the /usr/local/maldet/ directory. Open the directory and edit the configuration file conf.maldet with vi editor:

# cd /usr/local/maldetect/

# vi conf.maldet

In this file, edit the following lines to enable various feature and alerts
Enable email alert by changing the value to 1 :

email_alert=”1”
Type your email address :
email_alert=”your@domain.com

We will use the ClamAV clamscan binary as default scan engine because it provides a high-performance scan on large file sets. Change value to 1:
scan_clamscan=”1”
Next, enable quarantining to move malware to the quarantine automatically during the scan process. Chang value to 1:
quarantine_hits=”1”
Change value to 1, to enable clean based malware injections.
quarantine_clean=”1”

Save and exit, you can also change other values based on your requirement.

Testing Linux Malware Detect(LMD)

For testing LMD manual scan with the maldet command, you will use the maldet command to scan the web directory ‘/var/www/html’.
Download some malware file with the help of following commands in web root directory:
# cd /var/www/html
# wget http://www.eicar.org/download/eicar.com.txt
# wget http://www.eicar.org/download/eicar_com.zip

Next, scan the web root directory with the maldet command:

# maldet -a /var/www/html

Check the scan report with the following command:

# maldet –report 18882——-*

Other LMD Command

To ensure Maldet is up-to-date, run the command below:

# maldet -u


You can see the details of the option available by running the following command:

# maldet -h


Perform a scan for specific file extension only:

# maldet -a /var/www/html*.php

Get a list of all reports:

# maldet -e list


Restore files from the quarantine directory.

# maldet -s SCANID

Enable monitoring of a directory.
# maldet -m /var/www/html

CONCLUSION-

The above configuration will show how to configure Linux Malware Detect in CWP and scan for malware data in your server.

How to create Automated Backup for website files with shell script?

Backup

With the help of shell script and crontab you can take automated backup in server with the help of following the document.

Archive the content

Backing up your files using tar is very simple using the following command: 

# tar -cvpzf /backup/backupfilename.tar.gz /data/directory

A real example would be backing up the HTML folder for your website, my case:

# tar -cvpzf /backup/file_name.tar.gz /var/www/html

Tar command explained

tar = Tape archive

c = Create

v = Verbose mode will print all files that are archived.

p = Preserving files and directory permissions.

z = This will tell tar that to compress the files.

f = It allows tar to get the file name.

Now create backup script with the help of vi editor.

Create Backup Script

Now let’s add tar command in a bash script to make this backup process automatic. Also it is good to add some dynamic value in the name to make sure there is no overwriting of backup files. 

E.g. Create the file using the vi editor and paste below script.

# vi /backup.sh

Paste the following script and change your details.

#!/bin/bash

TIME=`date +%b-%d-%y`                                                # This Command will read the date.

BK_FILENAME=backup-domainname.com-$TIME.tar.gz    # The filename including the date.

SOURCE=/var/www/html                                                 # Source backup folder.

DESCT=/backup                                                           # Destination of backup file.

tar -czf $DESCT/$BK_FILENAME $SOURCE

Note: The only risk that can occur is to get out of disk memory if the source folder is big, but you can configure it by removing file after 30 days or any number of days with the help of the find command.

find /backup -type f -name ‘*.gz’ -mtime +15 -exec rm {} \;

Automation

In Linux, we can easily use the cron jobs in order to schedule task and perform the above backup task easily.                The cron jobs line has 6 parts see below explanation: Minutes Hours Day of Month Month Day of Week Command 0 to 59 0 to 23 1 to 31 1 to 12 0 to 6 Shell Command Open crontab editor utility:
#
crontab -e 

Note: the edit rules are similar with vi editor.
Paste the following text in the editor:
# M H DOM M DOW CMND
00 04 * * * /bin/bash /backup.sh
This will run the script every day at 04:00:00.
Check the rules of crontab with the help of the following command:
#
Crontab -l 

CONCLUSION

After the above configuration, you can take backup automatically and remove it in some specific period of time.

How to improve GTMetrix score of websites?

GTMetrix

It is a tool that is used to get more and more detailed reports about our site’s performance. It is a free tool that analyzes your page’s speed performance using Google Page Speed and YSlow. 

 

In addition, Google uses page speed in their ranking algorithms. Therefore, a faster performing site may rank higher in search engine results.

Earlier Report

 

To improve your score here, the first thing you must purchase a server from the VPS server provider who provides compression on their server like CloudMinister Technologies. Without server compression, you won’t be able to get a good score.

 

Few more steps you need to consider to get a good score from GTMetrix like Optimize images, Enable caching, Minify HTML, JavaScript code, activate CDN.

 

  • Enable Compression From server-side

 

 

It mostly happens that most of the server providers don’t enable compression by default, so we need to find those server providers who provide compression with the server.

 

 

  • Optimize Images

 

To get more score from GTMetrix we need to optimize all those images that we put on the websites because in large size images it takes more time to load, follow these steps to optimize images.

> Name your images descriptively and in plain language.

> Optimize your alt attributes carefully.

> Choose your image dimensions and product angles wisely.

> Reduce the file size of your images.

> Choose the right file type.

> Optimize your thumbnails.

> Use image sitemaps.

> Beware of decorative images.

> Use caution when using content delivery networks (CDN’s).

> Test your images.

 

 

  • Minify HTML , JavaScript code & CSS code

 

We need to Minify HTML & JavaScript as well as CSS code with this content will read fast by the browser and help your viewers to see the website more quickly. Cloudflare provides this feature to enhance the score on GTMetrix.

 

 

  • Activate CDN

 

A content delivery network (CDN) is a system of servers spread over multiple data centers located around the world. When a user visits your site they will be served content from the server closest to them.

The most popular CDN is Cloudflare – to activate you will need to sign up and add your site to a free plan. Once this is done you will need to change your nameservers so the domain looks towards Cloudflare. This can take up to 24 hours for the DNS to update but is usually much quicker.

After covering all the above points you will be able to get a better score over GTMetrix.

Conclusion – The above configuration shows how to achieve a better score on the GTMetrix, by following all these points your viewer will be able to visit your website more quickly.

File compression in Linux

Here you will learn about the file compression and the full overview of types of file compression

File compression used to contain two or more file & directory in smaller size rather than original. Compression means reduce size of file.

In linux have many types of file compression
1. gzip

2. bzip2
3. xz
4. zip

 

# du -sh filename/or/path (This command use to check the size of file)

# yes “string” > file_name (This command use to copy string into file)

Alert :- immediately press (ctrl + c) after use yes command.If you not press (ctrl +c) immediately file size increase every second.

example :- 

  1. gzip :-

gzip is used to compress file but gzip not reduce more  size as compared to others. gzip extension is .gz.   

# gzip file_name (This command used for compress the file in .gz extension)


Uncompress gzip command

# gunzip  file_name.gz (This command used to unzip .gz file)

Example:- 


Create compress and tar file simultaneously 

#tar cvzf destination\path/file_name.tar.gz /source/path/ (This command used to compress in gz format and convert in tar file)

Example:- 


Uncompress and untar  file simultaneously

# tar xvzf file_name.tar.gz (This command used for uncompressing and untar file those extensions have .tar.gz or .tgz)

Example:-
