Upgrading PHP 5.3 to 7.x on CentOS 6.10 (final) - Unmet Dependencies

Question

I am a bit rusty these days and could use some help. I've cracked opened a few old servers and have started the process of dusting them off. In the process I'm updating things like PHP. I regret to inform you I'm running 5.3.3. I would like to upgrade it to 7.3.

cat /etc/centos-release 
CentOS release 6.10 (Final)

My PHP version

php -v
PHP 5.3.3 (cli) (built: Mar 22 2017 12:17:33)

Alas, I'm having issues...

I am using the remi repo

yum install http://rpms.remirepo.net/enterprise/remi-release-6.rpm

And set my config manager as follows:

yum-config-manager --enable remi-php72

When I install PHP

yum install php php-mcrypt php-cli php-gd php-curl php-mysql php-ldap php-zip php-fileinfo

I get a series of dependency errors:

--> Finished Dependency Resolution
Error: Package: php-7.2.10-1.el6.remi.x86_64 (remi-php72)
           Requires: libgssapi_krb5.so.2()(64bit)
Error: Package: php-7.2.10-1.el6.remi.x86_64 (remi-php72)
           Requires: libdl.so.2(GLIBC_2.2.5)(64bit)
Error: Package: php-cli-7.2.10-1.el6.remi.x86_64 (remi-php72)
           Requires: libcrypt.so.1()(64bit)
And the list goes on....

I'm at a loss for how to go about addressing this and could use any help / insights you might have to offer.

Thank you in advance!

Solution

Everything is in the base/updates repository

• libgssapi_krb5.so.2 => krb5-libs-1.10.3-65.el6.x86_64
• libdl.so.2(GLIBC_2.2.5)(64bit) => glibc-2.12-1.212.el6.x86_64
• libcrypt.so.1()(64bit) => glibc-2.12-1.212.el6.x86_64

As some package are always there (e.g. glibc) Check you are really running CentOS 6.10

# cat /etc/redhat-release 
CentOS release 6.10 (Final)
# uname -a
Linux foo.bar 2.6.32-754.2.1.el6.x86_64 #1 SMP Fri Jul 13 12:50:12 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
# rpm -q glibc
glibc-2.12-1.212.el6.x86_64

Perhaps if you tried to update/upgrade iso. install?

Check that someone has not modified or disabled those base and updates repos.

Out of topic, issue is with base repo. More: this is wrong, IUS does NOT allow to "install php 7 besides the "official" php " (only SCLs allow parallel installation)

It seems like IUS repository for CentOS 6 only goes up to PHP 7.1 repo.ius.io/6/x86_64/packages/p
