CentOS 7 - 无法安装 PHP 7.3

Question

I want to enable php73 as default version and install all packages related to it. So I did:

$ sudo yum-config-manager --enable remi-php73

And then:

$ sudo yum install php php-pecl-mcrypt php-cli php-gd php-curl php-mysqlnd php-ldap php-zip php-fileinfo php-common php-xml php-fpm php-mbstring php-bcmath php-soap php-oci8

Right after, I can see that it wants to install PHP 8.0 ( remi-php80 , which breaks my project dependencies):

How can I enable & force installation of PHP 7.3 on Centos 7?

I want to avoid doing it manually like: $ sudo yum install php73 php73-php-cli php73-php-fpm

Answer 1

If you want PHP 7.3 you must only enable " remi-php73 " repository (and " remi-safe ", which is enabled by default).

According to yum output in your question " remi-php80 " is wrongly enabled. You can wheck which repositories are enabled using

# yum repolist

For a proper repository configuration, see the Wizard instructions

# yum-config-manager --disable 'remi-php*'
# yum-config-manager --enable remi-php73
# yum-config-manager --enable remi-safe

About mcrypt extension, I recommend you get rid of it, see About libmcrypt and php-mcrypt

And I think you don't need both php (mod_php for Apache HTTP Server) and php-fpm

And for php-oci8 , I recommend you read Installation of Oracle extensions for PHP
