Compilation, installation and use of PHP8.0 (detailed explanation)

The official version of PHP8.0 has been released for a long time. This article will introduce its installation and compare it with PHP7 using laravel. [Recommended: PHP Video Tutorial]

Installation and Configuration

The operating system used this timeUbuntu 18.04.4 LTS

Installation

1. Prepare necessary libraries

apt-get install -y autoconf libxml2-dev libsqlite3-dev \
libcurl4-openssl-dev libssl-dev libonig-dev libtidy-dev zlib1g-dev

2.Go to the official website to download the official version of 8.0 https://www.php.net/releases/8.0 /en.php

3. Unzip and install

tar php-8.0.0.tar.gzcd php-8.0.0
./configure --prefix=/opt/php8 --with-config-file-path=/opt/php8/etc \
--enable-fpm --enable-mysqlnd --enable-opcache --enable-pcntl \
--enable-mbstring --enable-soap --enable-zip --enable-calendar \
--enable-bcmath --enable-exif --enable-ftp --enable-intl --with-mysqli \
--with-pdo-mysql --with-openssl --with-curl --with-gd --with-gettext \
--with-mhash --with-openssl --with-mcrypt --with-tidy --enable-wddx \
--with-xmlrpc --with-zlibmakemake installcp php.ini-production /opt/php/etc/php.inicd /opt/php8/etccp php-fpm.conf.default php-fpm.confcp ./php-fpm.d/www.conf.default ./php-fpm.d/www.conf

4. Make a soft link

ln -s /opt/php8/bin/php /usr/bin/php8

5. Install composer

cd /opt/php8/bin/curl -sS https://getcomposer.org/installer | php8ln -s /opt/php8/bin/composer.phar /usr/bin/composer8
composer8 config -g repo.packagist composer https://mirrors.aliyun.com/composer/

6. Add a php8 .0 system service

vim /lib/systemd/system/php8.0-fpm.service

The content is as follows

[Unit]
Description=The PHP 8.0 FastCGI Process Manager
Documentation=man:php-fpm8.0(8)
After=network.target

[Service]
Type=simple
PIDFile=/var/run/php8.0-fpm.pid
ExecStart=/opt/php8/sbin/php-fpm --nodaemonize --fpm-config /opt/php8/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

Configuration

fpm-fpm, php.ini configuration

Same as PHP7, pay attention to user permissions

opcache configuration

PHP8 has an additional jit configuration, as follows

[opcache]
zend_extension=opcache.so
opcache.enable=1 
opcache.jit_buffer_size=100M
opcache.jit=1255

Start

systemctl start php8.0-fpm

laravel

Create a laravel project[Recommended: laravel video tutorial]

cd /opt/web
composer8 create-project --prefer-dist laravel/laravel php8

Configure it .env file

nginx configuration

nginx configuration is consistent with PHP7

server {
    listen 94;

    access_log  /tmp/test94.log main;

    root /opt/web/php8/public;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php {
        fastcgi_pass unix:/run/php/php8.0-fpm.sock;
        fastcgi_index /index.php;

        include fastcgi_params;

        fastcgi_split_path_info       ^(.+\.php)(/.+)$;
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Add an interface

laravel7's route writing method is somewhat problematic in laravel8. Change the writing method of RouteServiceProvider.php.
For example, for API routing, change $this->namespace to App\Http\Controllers\Api.

public function boot()
    {
        $this->configureRateLimiting();

        $this->routes(function () {
            Route::prefix('api')
                ->middleware('api')
		->namespace('App\Http\Controllers\Api')
                ->group(base_path('routes/api.php'));

            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/web.php'));
        });
    }

Others are the same, no need to modify.

Add a test interface to see:

Route::get('/test','WxController@test');

testThe interface checks a piece of data and returns it

toarray();
    }}

Comparison test PHP7

This I used PHP7.3 for the first time, the interface code is the same as PHP8, and opcache is enabled on both.

The server configuration is 1 core 2G, use ab to simply test.

ab -n 100 -c 10

The test results of PHP7.3 are as follows:
