Installation steps for new users

Installing PHP 7.x - 8.x for new users

To install PHP 7.x - 8.x on an Amazon Linux 2 AMI

Note

If necessary, replace PHP-7.x with the version you are using.

  1. Launch a new instance from the AMI.

  2. Run the following command:

    sudo yum install gcc-c++ zlib-devel
  3. Install PHP 7.x using amazon-linux-extras

    With Amazon Linux 2, you can use the Extras Library to install application and software updates on your instances. These software updates are known as topics. You can install a specific version of a topic or omit the version information to use the most recent version. For more information, Extras library (Amazon Linux 2).

    To do this, use the following steps;

    1. First, verify if amazon-linux-extras is already installed.

    2. If not installed, use the following command to install:

      sudo yum install -y amazon-linux-extras

    3. Confirm that PHP 7.x topic is available in the Amazon Linux 2 machine:

      sudo amazon-linux-extras | grep php

    4. From the output, review all PHP 7 topics and select the version you want:

      sudo amazon-linux-extras enable php7.x

    5. Install PHP packages from the repository. For example:

      sudo yum clean metadata

      sudo yum install php php-devel

  4. Download the Amazon ElastiCache Cluster Client.

    • Open the ElastiCache console at https://console.amazonaws.cn/elasticache/.

      Under the ElastiCache dashboard, go to ElastiCache Cluster Client and then choose the PHP7 version you want.

    • From command line, replace PHP-7.X with the desired PHP version, and replace the ARCH with desired architecture (X86 or arm) and for PHP >= 7.4 replace the OpenSSL with the desired OpenSSL version (openssl1.1 or openssl3). If you are using PHP > 7.4, remove OpenSSL suffix.

      wget https://elasticache-downloads.s3.amazonaws.com/ClusterClient/PHP-7.X/latest-64bit-<ARCH>-<OpenSSL>
  5. Use tar -zxvf to extract the downloaded file.

    tar -zxvf latest-64bit-<ARCH>-<OpenSSL>
  6. With root permissions, copy the extracted artifact file amazon-elasticache-cluster-client.so into /usr/lib64/php/modules.

    sudo mv amazon-elasticache-cluster-client.so /usr/lib64/php/modules/
  7. Add extension=amazon-elasticache-cluster-client.so into file /etc/php.ini

  8. If you downloaded ElastiCache Cluster Client with PHP 7.4 or higher, install OpenSSL 1.1.x or higher. Installation instructions for OpenSSL 1.1.1:

    sudo yum -y update sudo yum install -y make gcc perl-core pcre-devel wget zlib-devel wget https://www.openssl.org/source/openssl-1.1.1c.tar.gz tar xvf openssl-1.1.1c.tar.gz cd openssl-1.1.1c ./config make sudo make install sudo ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1

Installing PHP 5.x for new users

To install PHP 5 on an Amazon Linux AMI 2014.03 (64-bit and 32-bit)

  1. Launch an Amazon Linux instance (either 64-bit or 32-bit) and log into it.

  2. Install PHP dependencies:

    $ sudo yum install gcc-c++ php php-pear
  3. Download the correct php-memcached package for your Amazon EC2 instance and PHP version. For more information, see Downloading the installation package.

  4. Install php-memcached. The URI should be the download path for the installation package:

    $ sudo pecl install <package download path>

    Here is a sample installation command for PHP 5.4, 64-bit Linux. In this sample, replace X.Y.Z with the actual version number:

    $ sudo pecl install /home/AmazonElastiCacheClusterClient-X.Y.Z-PHP54-64bit.tgz
    Note

    Be sure to use the latest version of the install artifact.

  5. With root/sudo permission, add a new file named memcached.ini in the /etc/php.d directory, and insert "extension=amazon-elasticache-cluster-client.so" in the file:

    $ echo "extension=amazon-elasticache-cluster-client.so" | sudo tee --append /etc/php.d/memcached.ini
  6. Start or restart your Apache server.

    sudo /etc/init.d/httpd start

    sudo yum install gcc-c++ php php-pear
  3. Download the correct php-memcached package for your Amazon EC2 instance and PHP version. For more information, see Downloading the installation package.

  4. Install php-memcached. The URI should be the download path for the installation package:

    sudo pecl install <package download path>
  5. With root/sudo permission, add a new file named memcached.ini in the /etc/php.d directory, and insert extension=amazon-elasticache-cluster-client.so in the file.

    echo "extension=amazon-elasticache-cluster-client.so" | sudo tee --append /etc/php.d/memcached.ini

  4. Install php-memcached. The URI should be the download path for the installation package.

    $ sudo pecl install <package download path>
    Note

    This installation step installs the build artifact amazon-elasticache-cluster-client.so into the /usr/lib/php5/20121212* directory. Verify the absolute path of the build artifact, because you need it in the next step.

    If the previous command doesn't work, you need to manually extract the PHP client artifact amazon-elasticache-cluster-client.so from the downloaded *.tgz file, and copy it to the /usr/lib/php5/20121212* directory.

    $ tar -xvf <package download path> cp amazon-elasticache-cluster-client.so /usr/lib/php5/20121212/
  5. With root/sudo permission, add a new file named memcached.ini in the /etc/php5/cli/conf.d directory, and insert "extension=<absolute path to amazon-elasticache-cluster-client.so>" in the file.

    $ echo "extension=<absolute path to amazon-elasticache-cluster-client.so>" | sudo tee --append /etc/php5/cli/conf.d/memcached.ini
  6. Start or restart your Apache server.

    sudo /etc/init.d/httpd start

 

To install PHP 5 for SUSE Linux enterprise server 11 AMI (64-bit or 32-bit)

  1. Launch a SUSE Linux instance (either 64-bit or 32-bit) and log into it.

  4. Install php-memcached. The URI should be the download path for the installation package.

    $ sudo pecl install <package download path>
  5. With root/sudo permission, add a new file named memcached.ini in the /etc/php5/conf.d directory, and insert extension=amazon-elasticache-cluster-client.so in the file.

    $ echo "extension=amazon-elasticache-cluster-client.so" | sudo tee --append /etc/php5/conf.d/memcached.ini
  6. Start or restart your Apache server.

    sudo /etc/init.d/httpd start
Note

If Step 5 doesn't work for any of the previous platforms, verify the install path for amazon-elasticache-cluster-client.so. Also, specify the full path of the binary in the extension. In addition, verify that the PHP in use is a supported version. We support versions 5.3 through 5.5.

 

Other Linux distributions

On some systems, notably CentOS7 and Red Hat Enterprise Linux (RHEL) 7.1, libsasl2.so.3 has replaced libsasl2.so.2. On those systems, when you load the ElastiCache cluster client, it attempts and fails to find and load libsasl2.so.2. To resolve this issue, create a symbolic link to libsasl2.so.3 so that when the client attempts to load libsasl2.so.2, it is redirected to libsasl2.so.3. The following code creates this symbolic link.

cd /usr/lib64 $ sudo ln libsasl2.so.3 libsasl2.so.2
