PHP8.0正式版的编译安装与使用

2020-11-26发布了PHP8.0的正式版
介绍下它的安装，并使用laravel对比下PHP7

安装与配置

本次使用的操作系统Ubuntu 18.04.4 LTS

安装

1.准备必要库

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

2.去官网下载8.0正式版 https://www.php.net/releases/8.0/en.php

3.解压安装

tar php-8.0.0.tar.gz
cd 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-zlib
make
make install
cp php.ini-production /opt/php/etc/php.ini
cd /opt/php8/etc
cp php-fpm.conf.default php-fpm.conf
cp ./php-fpm.d/www.conf.default ./php-fpm.d/www.conf

4.做个软连接

ln -s /opt/php8/bin/php /usr/bin/php8

4.安装composer

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

4.添加一个php8.0的system service

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

内容如下

[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

配置

fpm-fpm，php.ini配置

和PHP7一样，注意下用户权限

opcache配置

PHP8多了一个jit配置，如下

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

启动

systemctl start php8.0-fpm

laravel

创建一个laravel项目

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

配置一下.env文件

nginx配置

nginx的配置和PHP7的一致

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;}
}

添加一个接口

laravel7的路由写法在laravel8中有点问题，改下RouteServiceProvider.php的写法。
比如API路由,将$this->namespace改为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'));});}

其他一样，不用修改。
加个测试接口看看：

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

test接口查一条数据并返回

<?phpnamespace App\Http\Controllers\Api;use App\Models\WareHouses;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Http\Request;
use Illuminate\Routing\Controller as BaseController;class WxController extends BaseController
{use AuthorizesRequests, DispatchesJobs, ValidatesRequests;public function test(Request $request){return WareHouses::find(1)->toarray();}
}

对比测试PHP7

本次使用PHP7.3，接口代码和PHP8一致，两者都开启opcache。

服务器配置是1核2G，用ab简单测试下。

ab -n 100 -c 10

PHP7.3的测试结果如下：
