After I showed last week what problems you can deal with when switching from PHP 5.6 to PHP 7, I would like to show you how to switch to PHP 7 at all. Since I am now migrating to CentOS with all servers, it will be the first time that it is not a Debian example. The good thing about CentOS is that it is a fairly stable distribution – every major release is supported for 10 years. The bad thing about CentOS is that many packages are in a fairly old version, which is only provided with bug and security fixes. In my web server installations, I would rather rather operate new versions to get new features.
When you install a newer version, you have several options: either compiling PHP 7 yourself or using a third repository that contains pre-compiled packages for PHP 7. In this case I have decided for the second. With ius.io there is a repository for CentOS 7, which contains the most important packages and should be maintained for a long time due to the support of the host rackspace .
To use the IUS repository, you must first install your RPM package, which takes care of configuring the repository in the system:
yum install wget yum install epel-release wget https://centos7.iuscommunity.org/ius-release.rpm sudo rpm -i ./ius-release.rpm rm ./ius-release.rpm
Update 05/21/2020: link changed to https://repo.ius.io/ius-release-el7.rpm and not support php7.1 you must use php72u or php73
yum install wget yum install epel-release wget https://repo.ius.io/ius-release-el7.rpm sudo rpm -i ./ius-release-el7.rpm rm ./ius-release-el7.rpm
Result:

In my case I install besides PHP synonymous always equal MariaDB and NGINX. The IUS repository also contains a more recent version of MariaDB. In order to install these, however, you must first remove the existing “mariadb-libs”. In the process, Postfix is also uninstalled – we will simply reinstall it afterwards:
yum remove mariadb-libs

Now we can install the desired software via the software administration – packages that are installed via IUS always contain the suffix “u” to make them easier to recognize and avoid collisions with standard packages:
yum install mariadb101u-server nginx php71u-cli php71u-fpm php71u-gd php71u-imap php71u-intl php71u-json php71u-ldap php71u-mbstring php71u-mcrypt php71u-mysqlnd php71u-pdo php71u-pear php71u-pgsql php71u-process php71u-pspell php71u-recode php71u-soap php71u-xml php71u-xmlrpc postfix

Basically one is now finished at this point and has its CentOS 7 equipped with PHP 7. In my case, however, there were a few more things to do, as I needed SSH support in my PHP. Since there is still no ready-made package for IUS (probably because the SSH support for PHP 7 is not yet stable ), I had to compile the extension myself.
To do this, we have to install additional, required packages:
yum install autoconf automake make openssl-devel php71u-devel unzip zip
Update 05/21/2020
yum install autoconf automake make openssl-devel php73-devel unzip zip
Result:

Next, fetch, compile, and install the current version of the “libssh2” library:
wget https://www.libssh2.org/download/libssh2-1.7.0.tar.gz tar -xzvf ./libssh2-1.7.0.tar.gz cd ./libssh2-1.7.0 ./configure make sudo make install make clean cd .. rm ./libssh2-1.7.0.tar.gz rm -Rf ./libssh2-1.7.0
On Github someone has made the effort to set up the sources for PHP 7 compileable – its changes will also be the basis for the future SSH module. To this Github repository I hanged myself and compiled everything myself. As soon as the stabilized packages with IUS was taken, one should of course switch to this:
wget https://github.com/Sean-Der/pecl-networking-ssh2/archive/master.zip unzip ./master.zip cd ./pecl-networking-ssh2-master phpize ./configure make sudo make install make clean cd .. rm ./master.zip rm -Rf ./pecl-networking-ssh2-master sudo sh -c "echo 'extension=ssh2.so' >/etc/php.d/20-ssh2.ini"
And you have already installed PHP 7 on your CentOS 7 and is still bleading-edge on the road.
Now start Nginx service , PHP-fpm service and Mariadb service.
systemctl enable nginx systemctl enable php-fpm systemctl enable mariadb service nginx start service php-fpm start service mariadb start
