I'm trying to install composer in my Ubuntu 16.04
with PHP version 5.6.*
.
I used:curl -sS https://getcomposer.org/installer | php
. But it is giving me error as follows:
All settings correct for using Composer
Downloading...
The "https://getcomposer.org/versions" file could not be downloaded: failed to open stream: Connection refused
Retrying...
The "https://getcomposer.org/versions" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:

The download failed repeatedly, aborting.
I do not have composer installed previously.
Why is composer not installing? Make sure you have no problems with your setup by running the installer's checks via curl -sS https://getcomposer.org/installer | php — –check . Try clearing Composer's cache by running composer clear-cache . Ensure you're installing vendors straight from your composer.
Step 1: Navigate to the official composer website. Step 2: Then click on the Download button. Step 3: Then click on the Composer-Setup.exe & download the file. Step 4: Then click on “Install for all users”.
To solve the Memory exhausted issue, you can try running composer with an Unlimited memory flag like this: php -d memory_limit=-1 /usr/local/bin/composer [COMMAND] or php -d memory_limit=-1 composer. phar [COMMAND] when using a local composer. If that doesn't help, you can upgrade your hosting plan.
I solved the issue by downloading https://curl.haxx.se/ca/cacert.pem and giving it's path in my etc/php/5.6/cli/php.ini
and etc/php/5.6/apache2/php.ini
.
Then after running sudo service apache2 restart && sudo apt install composer
just worked fine.
Open terminal and run php -r "var_dump(openssl_get_cert_locations());"
Note the location of default_cert_file
. It might say \usr\local\ssl\cert.pem
Verify that that file exists. If not, download the cacert.pem file from https://curl.haxx.se/ca/cacert.pem and place it in somewhere preferably in /usr/local/ssl
You now have a file is usr/local/ssl/cacert.pem
Open your php.ini and add the location of the file openssl.cafile=cacert.pem
Install composer
Run composer config --global cafile "/usr/local/ssl/cacert.pem"
I experienced this problem while using Laravel Homestead after I’d accidentally emptied the contents of this file: /etc/ssl/certs/ca-certificates.crt
What fixed it for me was:
sudo apt-get purge ca-certificates
sudo apt-get install ca-certificates
