I upgraded my WordPress host to CentOS7 with PHP7.3 and everything seemed fine until I went to upgrade and I got:<\/p>\n

Communicating with the WordPress servers is used to check for new versions, and to both install and update WordPress core, themes or plugins.<\/p>\n
our site is unable to reach WordPress.org at 198.143.164.251, and returned the error: cURL error 2:<\/p>\n
Also<\/p>\n
CURLE_FAILED_INIT (2)<\/span><\/p>\n Very early initialization code failed. This is likely to be an internal error or problem, or a resource problem where something fundamental couldn’t get done at init time.<\/p>\n The more I dug into this, the more I realized the problems I had were a symptom of a bigger problem. For example I tried running a straight curl command and it worked fine.<\/p>\n Because WordPress runs curl from within PHP I created a test script:<\/p>\n This script ran fine if I ran it from the command line using<\/p>\n php -f test.php<\/p>\n but if I called the same script from Apache, httpd24, I got the<\/p>\n Curl error: 2 I tried adding every type of debug option I could but I got not detail about what was going on.<\/p>\n When I did the setup of this host I was aware that PHP’s preferred, faster, way of running PHP on a website was using “fpm”. However I felt that since my site was small and not too busy it was unnecessary work, so didn’t use it.<\/p>\n My lack of success and frustration encouraged me to try out fpm.<\/p>\n First thing I had to erase rh-php72-php using:<\/p>\n yum erase rh-php72-php<\/p>\n Then I needed to install rh-php72-php-fpm using<\/p>\n yum install rh-php72-php-fpm<\/p>\n At this point PHP is not being executed by Apache. If you were to restart Apache it would simply return the text of the test.php file.<\/p>\n We need to edit the httpd.conf so:<\/p>\n nano \/opt\/rh\/httpd24\/root\/etc\/httpd\/conf\/httpd.conf<\/p>\n In the VirtualHost add:<\/p>\n ProxyPassMatch ^\/(.*\\.php)$ fcgi:\/\/127.0.0.1:9000\/srv\/www\/zoyinc\/$1<\/p>\n You will note that “\/srv\/www\/zoyinc” is the root folder, or “DocumentRoot”, for this VirtualHost.<\/p>\n For my config this resulted in:<\/p>\n Note the addition of “DirectoryIndex index.php”. This is very important for WordPress in particular.<\/p>\n You need to make the same change for the Apache ssl config:<\/p>\n nano \/opt\/rh\/httpd24\/root\/etc\/httpd\/conf.d\/ssl.conf<\/p>\n So the ssl.conf should have a VirtualHost similar to:<\/p>\n We now need to enable and then start the fpm service:<\/p>\n systemctl enable rh-php72-php-fpm.service Finally restart Apache:<\/p>\n service httpd24-httpd restart<\/p>\n I had a similar problem with MythWeb which is the web based frontend for MythTV. This also runs on PHP. However in this case I had it running under “\/mysthweb” not at the root.<\/p>\n My changes were to:<\/p>\n \/opt\/rh\/httpd24\/root\/etc\/httpd\/conf.d\/mythweb.conf<\/p>\n Unfortunately this broke MythWeb and it transpires this was because the sections under “Directory ..” were not recognized specifically the section:<\/p>\n I had to move the setenv commands about “<Directory…” and then mythweb worked again.<\/p>\n During this exercise I found another option that also worked for mythweb and didn’t involve ProxyPass and DIDN’T involve moving the setenv commands:<\/p>\nIts not a WordPress problem<\/h1>\n
