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.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.做个软连接
ln -s /opt/PHP8/bin/PHP /usr/bin/PHP8
5.安装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/
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
opcache配置
[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【推荐：laravel视频教程】
cd /opt/web composer8 create-project --prefer-dist laravel/laravel PHP8
配置一下.env文件
Nginx配置
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;
}
}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：
