How to install PHP7 on CentOS7

This article will introduce to you how to install PHP7 on CentOS7. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

The default PHP version of CentOS7 is PHP5, but if we want to install PHP7, we do not need to delete the existing PHP5, just upgrade PHP to PHP7.

Use the yum provides php command to obtain the CentOS7 PHP package installation status. What is shown is that the latest version that can be installed in the existing installation source is: php-5.4.16-46.el7.x86_64

Before installing PHP7, it is recommended to upgrade and update the CentOS7 installation package:

yum -y update: Upgrade all software packages and also upgrade the software and system kernel;

yum -y upgrade: Just upgrade all software packages, but not upgrade the software and system kernel.

We use the second item here: yum -y upgrade to upgrade.

After completion, restart httpd: systemctl restart httpd.service: Restart httpd.

Usage: index.php phpinfo(): Test, no php information page is displayed, indicating that php configuration is required.

Use: yum remove php-common -y: Remove the php-common installed on CentOS7 so that new php-common can be installed. This step deletes the original php5 of CentOS.

Because the yum source of Linux does not exist in php7.x, we must first change the yum source:

r

pm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

After executing the above command, use: php -v: Display

-bash: php: command not found: It means that you need to continue to configure php7.

Use: sudo yum list php*: View the PHP version that can currently be installed (the latest version).

You can see that the latest version of PHP that can be installed is: php72w.

Install php72w: sudo yum -y install php72w: .

After executing the above command, use: php -v: display

-bash: php: command not found:

Although the version information after the successful installation of PHP7 is not displayed, However, php72w has been successfully installed at this time, and the httpd server needs to be restarted to make the newly installed php72w take effect.

After completion, use: systemctl restart httpd.service: Restart httpd.

Use browser: index.php phpinfo(): Test, the php information page will appear, indicating that httpd has been initially fully configured with php72w.

Then, in order to solve the problem of using: php -v: the command does not display the php72w version, and to make php72w more robust, we recommend installing the php72 extension:

Extension installation 1:

yum install php72w-common php72w-fpm php72w-opcache php72w-gd php72w-mysqlnd php72w-mbstring php72w-pecl-redis php72w-pecl-memcached php72w-devel

The above command will install a total of 30 expansion packages. The installation process is slow, please wait patiently. . .
The installed expansion packages are as follows:

php-api, php-bz2, php-calendar, php-ctype, php-curl, php-date, php-exif, php-fileinfo, php-filter, php-ftp, php-gettext, php-gmp, php-hash, php-iconv, php-json, php-libxml, php-openssl, php-pcre, php-pecl-Fileinfo, php-pecl-phar, php-pecl-zip, php-reflection, php-session, php-shmop, php-simplexml, php-sockets, php-spl, php-tokenizer, php-zend-abi, php-zip, php-zlib
