Findout the ip

ip addr

Load the site using the URL and it should display ‘Welcome to nginx!’ message.



Install OpenSSL CentOS Linux

OpenSSL – Supports the HTTPS protocol. Required by the NGINX SSL module and others.

Run the following commands to install openssl

cd /tmp/
wget http://www.openssl.org/source/openssl-1.0.2o.tar.gz
tar -zxf openssl-1.0.2o.tar.gz
cd openssl-1.0.2o
./Configure linux-x86_64 --prefix=/usr 
make install

You can verify the installation by issuing the following command.

openssl -version

Install NginX CentOS 7

Add Nginx Repository

To add the CentOS 7 EPEL repository, open terminal and use the following command:

sudo yum install epel-release

Install Nginx

Now that the Nginx repository is installed on your server, install Nginx using the following yum command:

sudo yum install nginx -y

Start Nginx

Nginx does not start on its own. To get Nginx running, type:

sudo systemctl start nginx

If you are running a firewall, run the following commands to allow HTTP and HTTPS traffic:

sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --reload

You can do a spot check right away to verify that everything went as planned by visiting your server’s public IP address in your web browser (see the note under the next heading to find out what your public IP address is if you do not have this information already):


Before continuing, you will probably want to enable Nginx to start when your system boots. To do so, enter the following command:

sudo systemctl enable nginx

Install Redis CentOS 7 Linux

Run the following commands to install redis

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make test
make install

Create a directory where to store your Redis config files and your data:

mkdir /etc/redis
mkdir /var/redis

Copy the init script that you’ll find in the Redis distribution under the utils directory into /etc/init.d. We suggest calling it with the name of the port where you are running this instance of Redis. For example:

cp utils/redis_init_script /etc/init.d/redis_6379

Copy the template configuration file you’ll find in the root directory of the Redis distribution into /etc/redis/ using the port number as name, for instance:

cp redis.conf /etc/redis/6379.conf

Create a directory inside /var/redis that will work as data and working directory for this Redis instance

mkdir /var/redis/6379

Edit the configuration file, making sure to perform the following changes:

vi /etc/redis/6379.conf

Set daemonize to yes (by default it is set to no).
Set the pidfile to /var/run/redis_6379.pid (modify the port if needed).
Change the port accordingly. In our example it is not needed as the default port is already 6379.
Set your preferred loglevel.
Set the logfile to /var/log/redis_6379.log
Set the dir to /var/redis/6379 (very important step!)

Finally add the new Redis init script to all the default runlevels using the following command

chkconfig --add redis_6379

Start Redis instance.

/etc/init.d/redis_6379 start

Check if Redis is working

redis-cli ping

Install PHP CentOS From Source CentOS Linux

Install required tools for compilation

In order to compile PHP from source you need to install few tools and libraries. First you need EPEL repository to be enabled. This repository contains more recent version of packages.

sudo yum install epel-release -y

Once you have it installed execute following command to install required packages

yum install autoconf libtool re2c bison libxml2-devel bzip2-devel libcurl-devel libpng-devel libicu-devel gcc-c++ libmcrypt-devel libwebp-devel libjpeg-devel openssl-devel libxslt-devel -y

Download and unpack PHP Source code

Next step is downloading PHP source code. Easiest option is to download it from GitHub PHP releases. Choose the version you would like to install. In my case it’s 7.2.3. Copy link to tar.gz archive and execute following commands:

curl -O -L https://github.com/php/php-src/archive/php-7.1.18.tar.gz

tar -xvf php-7.1.18.tar.gz

cd php-src-php-7.1.18/

It will download the archive from GitHub, unpack the sources and change working directory to unpacked sources.

Compile PHP

Now it’s time to compile PHP. First we need to build configure command. In order to do that execute following command:

./buildconf --force

Once configure command is created we can use it to configure PHP installation. This process will enable certain PHP extensions such as PDO, FPM, OPCache, GD library etc. If you need any libraries that are not provided here, you can execute ./configure –help option and check if there is something you need. Following command will install PHP with most common extensions:

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-freetype-dir=/usr/include/freetype2 --disable-short-tags --enable-xml --enable-cli --with-openssl --with-pcre-regex --with-pcre-jit --with-zlib --enable-bcmath --with-bz2 --with-curl --enable-exif --with-gd --enable-intl --with-mysqli --enable-pcntl --with-pdo-mysql --enable-soap --enable-sockets --with-xmlrpc --enable-zip --with-webp-dir --with-jpeg-dir --with-png-dir --enable-json --enable-hash --enable-mbstring --with-mcrypt --enable-libxml --with-libxml-dir --enable-ctype --enable-calendar --enable-dom --enable-fileinfo --with-mhash --with-incov --enable-opcache --enable-phar --enable-simplexml --with-xsl --with-pear

Apart from enabling extensions command above will also set where PHP will be installed. In my case it’s /usr/local/php location. If you will want to remove compiled PHP you will simply have to remove entire directory given under –prefix option.

Next it’s time to compile PHP. Please be aware that it takes few minutes:

make clean
make test

Install compiled PHP

Once PHP is compiled it is time to install it. Simply execute following command:

sudo make install

php.ini and OPCache configuration

Second thing is php.ini file. After installation php.ini file should located in /usr/local/php/lib. This is only the location. After compiling from source You won’t anything there so we need to copy it from uncompressed sources.

cd /usr/local/php/lib
cp /tmp/php-src-php-7.1.18/php.ini-development ./php.ini
vi php.ini

Add PHP to $PATH

We can do one more thing to make our life easier:) Add PHP executable to PATH, so we’ll be able to call php command from every directory.

echo 'pathmunge /usr/local/php/bin' > /etc/profile.d/php.sh

Execute such command, log out, log in and You’ll be able to execute:

php -v

Install Apache From Source Centos Linux

Follow the below steps to install apache in CentOS 7

Install EPEL Repository

In order to install EPEL repository execute following command:

sudo yum install epel-release -y

Install required tools for compilation

sudo yum install autoconf expat-devel libtool libnghttp2-devel pcre-devel -y

Download and unpack source code

Here are the links to the packages:

Apache httpd – https://github.com/apache/httpd/releases
APR – https://github.com/apache/apr/releases
APR-util https://github.com/apache/apr-util/releases

wget https://github.com/apache/httpd/archive/2.4.33.tar.gz
wget https://github.com/apache/apr/archive/1.6.3.tar.gz
wget https://github.com/apache/apr-util/archive/1.6.1.tar.gz
tar -zxvf 2.4.33.tar.gz
tar -zxvf 1.6.3.tar.gz
tar -zxvf 1.6.1.tar.gz

APR and APR-Util

Apache requires APR library for compilation. You need to copy the source codes to correct directory:

cp -r apr-1.6.3 httpd-2.4.33/srclib/apr
cp -r apr-util-1.6.1 httpd-2.4.33/srclib/apr-util

It’s important to not to include version number in APR directories. If you just copy apr-1.6.3 without changing the name, it will give you a warning about missing apr directory.

Compile source code

cd httpd-2.4.33
./configure --enable-so

Install HTTPD

sudo make install

Add Apache executables to PATH

If you try to type httpd -v in your command line, it will result in command not found. That’s because httpd is not on your $PATH. I’d like to have all executables from Apache available from everywhere. In order to achieve that, create file

sudo vi /etc/profile.d/httpd.sh

and paste there following contents:

pathmunge /usr/local/apache2/bin

Save the file, log out and log in from your current session to reload your profile. After that you should be able to use httpd -v command:)

Add Systemd entry

Starting, restarting, and enabling Apache on server start via systemctl command is very important thing. You need to create another file:

sudo vi /etc/systemd/system/httpd.service

and paste there following contents:

Description=The Apache HTTP Server

ExecStart=/usr/local/apache2/bin/apachectl -k start
ExecReload=/usr/local/apache2/bin/apachectl -k graceful
ExecStop=/usr/local/apache2/bin/apachectl -k graceful-stop


Save the file and reload the systemctl daemon

sudo systemctl daemon-reload

Now you can try to start your Apache httpd server with following command:

sudo systemctl start httpd

Create dedicated user and group for Apache

sudo groupadd www
sudo useradd httpd -g www --no-create-home --shell /sbin/nologin

Edit the httpd.conf file and update the user ad group.

User httpd
Group www

Now restart the server service httpd restart

So that’s it. You have fully working Apache httpd in latest version installed on your system .

This process might take some time, but you will have full control over httpd.


Install Memcached XAMPP Windows 10

Memcache is a caching system used to speed up web applications by holding small pieces of arbitrary data, it could be broadly compared to the $_SESSION variable in PHP, but memcache works across the whole application not just on a per user basis and has been successfully proven to make great gains in speed increases on web applications.

Memcache was designed with Linux in mind and not windows, so it has posed some installation issues because Windows users are not so familiar with having to compile code from source as memcache does not come with any installation software. Continue reading Install Memcached XAMPP Windows 10
