This post is kinda a reference & checklist for me to be used in future, as the installation of PHP Erlang Bridge (peb) wasn’t as simple to follow the installation steps stated in INSTALL file in the source package. If you’ve come across this page by any chance, may be it will be helpful for you as well.
Step 1: Install erlang and this is really easy
sudo yum install erlang
Step 2: Install php-devel package if you already didn’t. This package will provide the phpize tool that you’ll require to build the peb and any other php extensions) from source
sudo yum install php-devel
Step 3: Download and extract latest source archive of peb from http://code.google.com/p/mypeb/downloads/list and extract & phpize
wget http://mypeb.googlecode.com/files/peb-0.20b.tar.gz tar -xzf peb-0.20b.tar.gz cd peb_release phpize
Step 4: Now comes the tricky part, i.e. to run configure with special parameters. Find out where is the erl_interface package is installed, which was installed with erlang as a dependency and provides all the library and header files that will be required to configure the build script for peb. Get the first line (the installation path of erl_interface) of following command and use it in following step. I will refer this as {$ERL_INTERFACE_PATH} in the next step.
rpm -ql erlang-erl_interface
Step 5: Execute following command based on the architecture of your CentOS installation
# use this if you have 64 bit architecture
./configure CC="gcc -m64 -L{$ERL_INTERFACE_PATH}/lib -I{$ERL_INTERFACE_PATH}/include" --enable-peb
# use this if you have 32 bit architecture
./configure CC="gcc -L{$ERL_INTERFACE_PATH}/lib -I{$ERL_INTERFACE_PATH}/include" --enable-peb
Step 6: Now follow the rest of the steps mentioned in INSTALL document to install the php extension.
make sudo make install
Step 7: Edit php.ini to add the following line
extension=peb.so
Step 8: Restart your web server (usually apache httpd)
sudo service httpd restart
Now you have installed peb extension and ready to start play with examples explained in peb wiki
Happy erlanging with php 🙂
