.. _custom_startup_commands: *********************** Custom startup commands *********************** You can provide custom startup commands via bash scripts to each of the PHP container. This may be useful to specify additional software to install or additional settings to apply during the initial startup. **Table of Contents** .. contents:: :local: General ======= You can add custom ``bash`` scripts for each PHP version separately. Provided scripts must end by the file extension ``.sh`` and should be executable. Anything not ending by ``.sh`` will be ignored. Where ----- Startup scripts can be added to ``cfg/php-startup-X.Y/``. See the directory structure for PHP startup script directories inside ``./cfg/`` directory: .. code-block:: bash host> ls -l path/to/devilbox/cfg/ | grep 'php-startup' drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-5.2/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-5.3/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-5.4/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-5.5/ drwxr-xr-x 2 cytopia cytopia 4096 Apr 3 22:04 php-startup-5.6/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-7.0/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-7.1/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-7.2/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-7.3/ drwxr-xr-x 2 cytopia cytopia 4096 Mar 5 21:53 php-startup-7.4/ Custom scripts are added by placing a file into ``cfg/php-startup-X.X/`` (where ``X.X`` stands for your PHP version). The file must end by ``.sh`` in order to be executed by the PHP container. Some of the PHP startup directories contain a few example files with the file suffix ``-example``. If you want to use them, copy these files to a new name without the ``-example`` suffix and ensure they end by ``.sh``. When ---- The scripts will be executed by the PHP container during initial startup. Whenever you change your scripts, ensure to restart the Devilbox. How --- The scripts will always be executed inside the PHP container (Debian Linux) and will be run with ``root`` privileges. Examples ======== The following examples should already exist as example files within ``cfg/php-startup-X.Y``, but will covered here as well to show some real world examples of what can be done with startup scripts. Installing Microsoft ODBC driver -------------------------------- This example will add Microsofts ODBC driver to PHP 7.1. These drivers are required in order to make the PHP modules ``pdo_sqlsrv`` and ``sqlsrv`` work. The two mentioned modules are already available in the PHP container, but are explicitly disabled via :ref:`env_file_php_modules_disable`. They won't work without the ODBC driver installed, which unfortunately cannot be bundled, as it requires every user to accept a license/EULA by Microsoft. .. code-block:: bash # Navigate to starup dir of PHP 7.1 host> cd path/to/devilbox/cfg/php-startup-7.1 # Create an .sh file host> touch ms-odbc.sh # Open the file in your favourite editor host> vi ms-odbc.sh Paste the following into ``ms-obbc.sh`` and **ensure to accept the EULA** by changing ``ACCEPT_EULA=N`` to ``ACCEPT_EULA=Y``. .. code-block:: bash :caption: ms-odbc.sh :emphasize-lines: 18 !/bin/bash # # This script will automatically install the Microsoft ODBC driver for MsSQL # support for PHP during startup. # # In order for it to work, you must read and accept their License/EULA: # https://odbceula.blob.core.windows.net/eula17/LICENSE172.TXT # # ------------------------------------------------------------------------------------------------ # EDIT THE VARIABLE BELOW TO ACCEPT THE EULA (If you agree to their terms) # ------------------------------------------------------------------------------------------------ ### ### Set this to "Y" (capital 'Y') if you accept the EULA. ### ACCEPT_EULA=N # ------------------------------------------------------------------------------------------------ # DO NOT EDIT BELOW THIS LINE # ------------------------------------------------------------------------------------------------ ### ### Where to retrieve the deb package ### MSODBC_URL="https://packages.microsoft.com/debian/8/prod/pool/main/m/msodbcsql17/" ### ### Pre-flight check ### if [ "${ACCEPT_EULA}" != "Y" ]; then echo "MS ODBC EULA not accepted. Aborting installation." exit 0 fi ### ### EULA accepted, so we can proceed ### # Extract latest *.deb packate MSODBC_DEB="$( curl -k -sS "${MSODBC_URL}" | grep -Eo 'msodbcsql[-._0-9]+?_amd64\.deb' | tail -1 )" # Download to temporary location curl -k -sS "${MSODBC_URL}${MSODBC_DEB}" > "/tmp/${MSODBC_DEB}" # Install ACCEPT_EULA="${ACCEPT_EULA}" dpkg -i "/tmp/${MSODBC_DEB}" # Remove artifacts rm -f "/tmp/${MSODBC_DEB}" .. important:: The script will not work, if you have not accepted the EULA. Installing Oracle oci8 and pdo_oci PHP modules ---------------------------------------------- This example will install Oracle instaclient as well as PHP modules ``pdo_oci`` and ``oci8`` in order to use PHP to connect to Oracle. This startup script will only be provided to PHP 7.2 .. code-block:: bash # Navigate to starup dir of PHP 7.2 host> cd path/to/devilbox/cfg/php-startup-7.2 # Create an .sh file host> touch oracle.sh # Open the file in your favourite editor host> vi oracle.sh Paste the following into ``oracle.sh``: .. code-block:: bash :caption: oracle.sh #!/bin/bash # # https://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/ # # Install 'alien' to install rpm packages apt-get update -q DEBIAN_FRONTEND=noninteractive apt-get install -qq -y --no-install-recommends --no-install-suggests alien # Instantclient (basic lite) curl -o /tmp/oracle-instantclient18.3-basiclite-18.3.0.0.0-2.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/getPackage/oracle-instantclient18.3-basiclite-18.3.0.0.0-2.x86_64.rpm # Instantclient (devel) curl -o /tmp/oracle-instantclient18.3-devel-18.3.0.0.0-2.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/getPackage/oracle-instantclient18.3-devel-18.3.0.0.0-2.x86_64.rpm # Install RPMs alien -i /tmp/oracle-instantclient18.3-basiclite-18.3.0.0.0-2.x86_64.rpm alien -i /tmp/oracle-instantclient18.3-devel-18.3.0.0.0-2.x86_64.rpm # Rempve RPMs rm -f /tmp/oracle-instantclient18.3-basiclite-18.3.0.0.0-2.x86_64.rpm rm -f /tmp/oracle-instantclient18.3-devel-18.3.0.0.0-2.x86_64.rpm # Necessary symlinks ln -s /usr/lib/oracle/18.3/client64/lib/libmql1.so /usr/lib/ ln -s /usr/lib/oracle/18.3/client64/lib/libipc1.so /usr/lib/ ln -s /usr/lib/oracle/18.3/client64/lib/libnnz18.so /usr/lib/ ln -s /usr/lib/oracle/18.3/client64/lib/libons.so /usr/lib/ ln -s /usr/lib/oracle/18.3/client64/lib/libclntshcore.so.18.1 /usr/lib/ # Build and install PHP extension oci8 docker-php-ext-configure oci8 --with-oci8=instantclient docker-php-ext-install oci8 # Build and install PHP extension pdo_oci docker-php-ext-configure pdo_oci --with-pdo-oci=instantclient,/usr,18.3 docker-php-ext-install pdo_oci
