The Yoast SEO plugin in WordPress has started advising users to upgrade curl to the latest version. On CentoOS this can be done easily using the city-fan.org repo here: http://www.city-fan.org/ftp/contrib/yum-repo/ For a CentOS 6 server, here are the steps:
|
1 2 3 |
rpm -Uvh http://www.city-fan.org/ftp/contrib/yum-repo/city-fan.org-release-1-13.rhel6.noarch.rpm yum install libcurl |
Composer for PHP is an increasingly popular tool for managing packages within a PHP application. Here’s a link for more information: https://getcomposer.org/ On many of our Plesk servers we have multiple PHP versions install. The default at /usr/bin/php is provided by the Linux distribution and then there are additional version installed at /opt/plesk/php. Plesk lets us easily select the PHP version for each hosted website. But you can run into problems with composer using the wrong PHP version. A typical composer command might be:
|
1 |
php composer.phar install |
or
|
1 |
php composer.phar update |
To make our alternate PHP version work we need to instead do something like this:
|
1 |
export PATH=/opt/plesk/php/5.6/bin:$PATH; php composer.phar update |
So we override the default PHP by adding our preferred version to the front of the path.
Need mod_fcgid on a CentOS 6.2 or similar server? Check out this great how-to: https://www.howtoforge.com/how-to-set-up-apache2-with-mod_fcgid-and-php5-on-centos-6.2 I especially like the use of suexec. This howto worked on the first try! There are not many actual working mod_fcgid howtos! One issue that I did run into is the default MaxRequestLen is 131768 which is way to low so had to add this line:
|
1 |
FcgidMaxRequestLen 20971520 |
to /etc/httpd/conf.d/fcgid.conf.
If you need to disable zlib output compression from the .htaccess file, then just add the following line to the top of the file:
|
1 |
php_flag zlib.output_compression off |
Here’s a brilliant article on how to add python 2.7 and 3.3 to a CentOS server which defaults to 2.6 without breaking anything: http://toomuchdata.com/2014/02/16/how-to-install-python-on-centos/ Especially useful is the last section on creating and using an isolated environment.
