Upgrade Downgrade phiên bản PHP trong Cestos

Tác giả: Dương Nguyễn Phú Cường

Ngày đăng: 4 năm trước

Hôm nay tôi tiếp tục chia sẽ đến các bạn cách nâng cấp phiên bản PHP mặc định của Vestacp đó là phiên bản PHP 5.6 lên phiên bản PHP 7.x, Các bạn có biết rằng hiệu suất của WordPress 3.6+ trở lên khi chạy trên PHP 7 đã được cải thiện đáng kể so với WordPress trên PHP 5.6, như thời gian phản hồi, xử lý các request đồng thời..v.v

Đầu tiên việc bạn cần làm là kết nối SSH dưới tài khoản quản trị cao nhất root và kiểm tra cập nhật các gói phần mềm hiện tại đầu tiên bằng command lênh:

sudo yum update

Sau việc cập nhật hoàn tất bạn kiểm tra xem phiên bản PHP hiện tại đang cài đặt trên máy chủ của bạn bằng command lệnh:

php -v

Việc tiếp theo bạn cần làm là cài đặt gói yum-utils bằng command lệnh sau, yêu cầu cài đặt sẽ hỏi bạn có muốn cài không thì bạn gõ y nhấn Enter:

sudo yum install yum-utils

Việc tải và cài đặt gói yum-utils thành công thì đến đây bạn cần kích hoạt remi để tiến hành nâng cấp bằng command lệnh sau:

– Kích hoạt remi-php70 nếu bạn muốn nâng lên phiên bản PHP 7.0

sudo yum-config-manager --enable remi-php70

– Hoặc remi-php71 nếu bạn muốn nâng cấp lên PHP 7.1

sudo yum-config-manager --enable remi-php71

– Hoặc remi-php72 nếu bạn muốn nâng cấp lênh PHP 7.2

sudo yum-config-manager --enable remi-php72

Như vậy là việc kích hoạt remi đã thành công và tất cả còn lại là chạy lệnh cập nhật để tiến hành update phiên bản PHP, nếu có thông báo hỏi bạn muốn cập nhật/cài đặt bản mới không thì bạn gõ y và nhấn Enter:

sudo yum update

Khi việc cài đặt thành công bạn cần khởi động lại dịch vụ web server để phiên bản mới thực sự được cập nhật, bằng command lệnh sau:

– Nếu Máy chủ bạn cài đặt Vestacp Apache + NGINX thì bạn dùng command lệnh:

sudo service httpd restart

– Nếu Máy chủ bạn cài đặt Vestacp NGINX + PHP-FPM thì bạn dùng command lệnh:

sudo service php-fpm restart

Cuối cùng bạn cần kiểm tra lại phiên bản PHP cài đặt đã ok chưa bằng command lệnh:

php -v

Ví dụ sau khi cài đặt thành công và sử dụng lệnh php -v để kiểm tra như sau:

PHP 7.0.22 (cli) (built: Aug 2 2017 09:39:55) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies

Công việc đến đây có vẽ như là hoàn thành rồi, tuy nhiên bạn cũng đừng quên khóa tính năng cập nhật cho phiên bản PHP cũ đã cài lên máy chủ bằng các dòng lệnh sau:

sudo yum-config-manager --disable remi-php56
sudo yum-config-manager --disable remi-php55
sudo yum-config-manager --disable remi-php56-debuginfo
sudo yum-config-manager --disable remi-php55-debuginfo
sudo yum clean all
sudo yum update

Installing PHP 7.3.3 on CentOS 7.6

Install EPEL Repository

To install the latest PHP 7.3.3 on CentOS 7.6, you need to first install EPEL repositories.

yum install epel-release

Install Remi Repository

Remi is a third party repository that provides the latest versions of PHP.

yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Disable Remi PHP 5.4 repository

By default, the repository for PHP 5.4 is enabled and hence, to install the latest version of PHP, you need to disable this repo. The repositories can be enabled or disabled using the yum-config-manager command. This command is provided with the yum-utils package.

yum install -y yum-utils
yum-config-manager --disable remi-php54

Enable Remi PHP 7.3 repository

To enable Remi PHP 7.3 repository, run the command below.

yum-config-manager --enable remi-php73

Installing PHP 7.3.3 on CentOS 7.6

Now that we got the repositories to power this process, you can now install PHP 7.3.3 on CentOS 7.6.

yum install php

Once the installation, check the version by executing the command below;

php -v

PHP 7.3.3

If you need to install PHP extensions, you can search and install them by running the command below;

yum list php-*
yum install php-<extension_name>

Well, that is it about installing PHP 7.3.3 on CentOS 7.6. We hope this was informative. Enjoy

Just run

yum install yum-utils -y
yum-config-manager --disable remi-php5*
yum-config-manager --disable remi-php74
yum-config-manager --disable remi-test
yum-config-manager --enable remi-php73
yum remove php php-*
yum install roundcube phpmyadmin -y
service httpd restart or service php-fpm restart

CODE: SELECT ALL

yum remove php*

CODE: SELECT ALL

yum install php71-php-imap php71-php-process php71-php-pspell php71-php-xml php71-php-xmlrpc php71-php-pdo php71-php-ldap php71-php-pecl-zip php71-php-common php71-php php71-php-mcrypt php71-php-gmp php71-php-mysqlnd php71-php-mbstring php71-php-gd php71-php-tidy php71-php-pecl-memcache --enablerepo=remi

   Order Deny,Allow
   Deny from All

# phpMyAdmin upstream tarball
#
<Directory /usr/share/phpMyAdmin/libraries/>

4. after restart httpd service or reboot, all my problem is fixed :D

Setup Yum Repository

First of all, you need to enable Remi and EPEL yum repositories on your system. Use the following command to install EPEL repository on your CentOS and Red Hat 7/6 systems Use this command to install EPEL yum repository on your system

sudo yum install epel-release

and now execute one of the following commands as per your operating system version to install the Remi repository.

sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

Install PHP 7 on CentOS

Your system is prepared for the PHP installation from yum repositories. Use one of the following commands to install PHP 7.3 or PHP 7.2 or PHP 7.1 on your system based on your requirements.

## Install PHP 7.3 
yum --enablerepo=remi-php73 install php

## Install PHP 7.2 
yum --enablerepo=remi-php72 install php

## Install PHP 7.1 
yum --enablerepo=remi-php71 install php

I have installed the latest version PHP 7.3 on my system. Now running the following command to check the current active PHP version on my system.

Install PHP Modules

You may also need to install additional PHP modules based on your application requirements. The below command will install some more useful PHP modules.

### For PHP 7.3
yum --enablerepo=remi-php73 install php-xml php-soap php-xmlrpc php-mbstring php-json php-gd php-mcrypt
