How to install PHP7 on CentOS78

This article will introduce to you how to install PHP7 on CentOS78. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

1. 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

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

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.

3. 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.

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

rpm -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 you need to continue configuring php7.

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

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

6. 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.

7. 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.

8. Then, in order to solve the problem of using: php -v : command not displaying 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

上述命令一共会安装30个拓展包，安装过程较慢，请耐心等待。。。 安装的拓展包如下： 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 执行上述命令后，使用： php -v ：显示： PHP 7.2.16 (cli) ： 说明php72w开发环境基本安装完成。

9. In order to further strengthen php72w In the development environment, it is recommended to enter the following command to install a more comprehensive expansion package for php72w:
