Installing Passenger + Apache on an AWS production server
for Meteor apps + Red Hat 6 / CentOS 6 (with RPM)

This page describes the installation of Passenger through the following operating system or installation method: Red Hat 6 / CentOS 6 (with RPM). Not the configuration you are looking for? Go back to the operating system / installation method selection menu.

No Amazon Linux RPMs

Our YUM repository may not be used with Amazon Linux. Amazon Linux is too different from RHEL and CentOS. If you are on Amazon Linux, please go back to the operating system menu and select "Other / OS independent (generic installation method)".

On this page, we will install Passenger. After installing Passenger we can begin with deploying the app.

Step 1: upgrade your kernel, or disable SELinux

The first thing you need to do is to check on two things:

  1. Which kernel version are you running? You can find out by running uname -r.
  2. Is SELinux enabled? You can find out by running grep SELINUX /etc/selinux/config. If it says "enforcing" or "permissive", then SELinux is enabled. If it says "disabled", then SELinux is disabled.

If SELinux is enabled, then Passenger requires kernel >= 2.6.39. If your kernel is not recent enough, then there are two things you can do:

  1. Disable SELinux completely. Edit /etc/selinux/config, set SELINUX=disabled and reboot. Note that merely setting SELinux to permissive mode is not enough.


  2. Upgrade your kernel to at least 2.6.39.

If your kernel version was already at least 2.6.39, or if SELinux was already disabled, then you can skip to the next step.

Step 2: enable EPEL

Passenger requires EPEL. The instructions differ depending on whether you are on Red Hat or CentOS.

Red Hat

Step 1:
install EPEL package

If your system is 64-bit:

$ if ! rpm -q epel-release; then sudo yum install -y yum-utils \; fi
$ sudo yum-config-manager --enable epel

If your system is 32-bit:

$ if ! rpm -q epel-release; then sudo yum install -y yum-utils \; fi
$ sudo yum-config-manager --enable epel
Step 2:
enable the 'optional' repository
Enable the optional repository (rhel-6-server-optional-rpms). This can be done by enabling the RHEL optional subchannel for RHN-Classic. For certificate-based subscriptions see Red Hat Subscription Management Guide.


$ sudo yum install -y epel-release yum-utils
$ sudo yum-config-manager --enable epel

Step 3: install Passenger packages

These commands will install Passenger + Apache module through Phusion's YUM repository.

# Install various prerequisites
sudo yum install -y pygpgme curl

# Add our el6 YUM repository
sudo curl --fail -sSLo /etc/yum.repos.d/passenger.repo

# Install Passenger + Apache module
sudo yum install -y mod_passenger

Step 4: restart Apache

Now that the Passenger Apache module is installed, restart Apache to ensure that Passenger is activated:

$ sudo service httpd restart

Step 5: check installation

After installation, please validate the install by running sudo /usr/bin/passenger-config validate-install. For example:

$ sudo /usr/bin/passenger-config validate-install
 * Checking whether this Phusion Passenger install is in PATH... ✓
 * Checking whether there are no other Phusion Passenger installations... ✓

All checks should pass. If any of the checks do not pass, please follow the suggestions on screen.

Finally, check whether Apache has started the Passenger core processes. Run sudo /usr/sbin/passenger-memory-stats. You should see Apache processes as well as Passenger processes. For example:

$ sudo /usr/sbin/passenger-memory-stats
Version: 5.0.8
Date   : 2015-05-28 08:46:20 +0200

---------- Apache processes ----------
PID    PPID   VMSize    Private  Name
3918   1      190.1 MB  0.1 MB   /usr/sbin/httpd

----- Passenger processes ------
PID    VMSize    Private   Name
12517  83.2 MB   0.6 MB    Passenger watchdog
12520  266.0 MB  3.4 MB    Passenger core
12531  149.5 MB  1.4 MB    Passenger ust-router

If you do not see any Apache processes or Passenger processes, then you probably have some kind of installation problem or configuration problem. Please refer to the troubleshooting guide.

Step 6: update regularly

Apache updates, Passenger updates and system updates are delivered through the YUM package manager regularly. You should run the following command regularly to keep them up to date:

$ sudo yum update

After an update, you should restart Apache. Doing so will automatically restart Passenger too.

Next step

Now that you have installed Passenger, you are ready to deploy your Meteor application on the production server!
