Installing Expect on WHM/CENTOS

This is an installation procedure that would work on 5.6 PHP. Not sure if it would work on higher PHPs.

Go to SSH/putty or whatever you use and install these dependencies.

1. Install PHP and its Development Framework
   

yum install php php-devel php-common

2. Install php-pear (PHP Extension and Application Repository)

  yum install php-pear

 To verify whether pear is installed properly or not, type command pear, there you will get

 list of command like discover-channel, upgrade,upgrade-all,if pear is successfully installed.

3. Install Tool command language (TCL) and TK, required for expect package

  yum install tcl tcl-devel tk tk-devel

4. Install Expect package required for php-expect

  yum install expect expect-devel

5. Install php-expect using pecl

  pecl install expect

 sometimes it may give error regarding channel,then use the path mentioned in suggestion like

channel://pecl.php.net/expect-0.3.1

 After successful installation of expect package, add the following line under extension in

 php.ini file (this will also be shown after successful installation of expect function)

 extension = expect.so
