Installing PHP 7.2.11 in CentOS 7.4 with pthreads enabled

This steps are meant for PHP CLI threading applications.  So web related appications are not installed along with.

OS Version: CentOS Linux release 7.4.1708 (Core)

First we need to install  PHP. Version used is php-7.2.11

1. Download php-7.2.11.tar.gz source from http://php.net/get/php-7.2.11.tar.gz/from/a/mirror
2. Extract to /usr/src
 
3. cd /usr/src/php-7.2.11
4. ./configure --with-config-file-path=/usr/local/lib --with-tsrm-pthreads --enable-pthreads=shared --enable-maintainer-zts --enable-sockets
5. make
6. make test
7. make install
8. To see the php version installed
     php -v

Now we need to install Pthreads. Source is taken from Github.

1. Download from https://github.com/krakjoe/pthreads.git
2. Extract to /usr/src/php-7.2.11/ext
3. This step may not be required, but this is how it got worked for me and i didnt tried the other way.      Rename the extracted file from pthreads-master to pthreads.
      mv /usr/src/php-7.2.11/ext/pthreads-master /usr/src/php-7.2.11/ext/pthreads
4. cd /usr/src/php-7.2.11/ext/pthreads
5. phpize
6. ./configure
7. make
8. make test
9. make install

Now we require to Rebuild our PHP installation

1. cd /usr/src/php-7.2.11
2. make clean
3. rm -f configure && ./buildconf --force
4. ./configure --with-config-file-path=/usr/local/lib --with-tsrm-pthreads --enable-pthreads=shared --enable-maintainer-zts --enable-sockets
5. make
6. make test
7. make install
   At end of make install note this path
    Installing shared extensions:     /usr/local/lib/php/extensions/no-debug-zts-20170718/

Next is the important and final step, to edit the configuration file (php.ini)
1. Give command -> php --ini
   Output ->
    Configuration File (php.ini) Path: /usr/local/lib
    Loaded Configuration File:         (none)
    Scan for additional .ini files in: (none)
    Additional .ini files parsed:      (none)

2. Copy file from /usr/src/php-7.2.11 to /usr/local/lib and rename the file to php.ini
    cp /usr/src/php-7.2.11/php.ini-development /usr/local/lib/php.ini

3. Give command -> php --ini
   Output ->
    Configuration File (php.ini) Path: /usr/local/lib
    Loaded Configuration File:         /usr/local/lib/php.ini
    Scan for additional .ini files in: (none)
    Additional .ini files parsed:      (none)

   Now the Configuration file is loaded

4. Add this line to /usr/local/lib/php.ini below
    extension=/usr/local/lib/php/extensions/no-debug-zts-20170718/pthreads.so


5. Shows the modules loaded
     php -m

    In the loaded modules you shoud be able to see the pthreads
