These instructions only apply in specific cases. Specifically CentOS machines, running in the Rackspace Cloud, IUS the Rackspace provided repo, provides several things not usually available within the CentOS repo, without you manually compiling more recent versions. One of them is the latest version of PHP7.0 and PHP7.1.<\/p>\n
I wanted to quickly document the process, since it is a relatively simple process, and, can actually be done without any maintenance window, if you know what your doing, with very minimal, (if any) disruption to running sites. an apachectl graceful, actually, should be enough. Since apachectl gracefully restarts apache httpd, the downtime you’ll see will be super minimal. Expect nobody to notice you upgraded to PHP7 if you do this right. <\/p>\n
If you do this incorrectly, you will break the PHP installation, and worse, break all of the sites using mod_php. Lets take a look at the steps:<\/p>\n
Step 1. Check available PHP modules provided by presently configured REPO <\/strong><\/p>\n As we can see php7 is there. Great. But what about the php packages they have already? That’s coming up next.<\/p>\n Step 2. Check presence of plugin replace, we’ll use this to upgrade to mod_php70 once we’re ready <\/strong><\/p>\n Step 3. Run a mock yum replace <\/strong><\/p>\n Naturally, if you are satisfied that you do not need php53u-zts, the only php module which is not supported by PHP7, then you can proceed. <\/p>\n If you are wondering what ZTS is, The php-zts package contains a module for use with the Apache HTTP ZTS is not required for MPM prefork, and is generally only used with MPM worker, afaik. So as long as your using prefork apache httpd your fine;<\/p>\n In our case prefork is being used, not worker. So I don’t think ZTS being missing is going to affect us. So we can proceed with typing ‘y’.<\/p>\n And’ thats pretty much how you upgrade to php7, it’s really easy with Rackspace IUS.<\/p>\n","protected":false},"excerpt":{"rendered":" These instructions only apply in specific cases.
