PHP8编译安装

安装

1.准备必要库

1. apt-get install -y autoconf libxml2-dev libsqlite3-dev \
2. 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

1. tar php-8.0.0.tar.gzcd php-8.0.0
2. ./configure --prefix=/opt/php8 --with-config-file-path=/opt/php8/etc \
3. --enable-fpm --enable-mysqlnd --enable-opcache --enable-pcntl \
4. --enable-mbstring --enable-soap --enable-zip --enable-calendar \
5. --enable-bcmath --enable-exif --enable-ftp --enable-intl --with-mysqli \
6. --with-pdo-mysql --with-openssl --with-curl --with-gd --with-gettext \
7. --with-mhash --with-openssl --with-mcrypt --with-tidy --enable-wddx \
8. --with-xmlrpc --with-zlib
9. make 
10. make install
11. cp php.ini-production /opt/php/etc/php.ini
12. cd /opt/php8/etc
13. cp php-fpm.conf.default php-fpm.conf
14. cp ./php-fpm.d/www.conf.default ./php-fpm.d/www.conf

4.做个软连接

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

5.安装composer

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

6.添加一个php8.0的system service

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

内容如下

1. [Unit]
2. Description=The PHP 8.0 FastCGI Process Manager
3. Documentation=man:php-fpm8.0(8)
4. After=network.target
5. [Service]
6. Type=simple
7. PIDFile=/var/run/php8.0-fpm.pid
8. ExecStart=/opt/php8/sbin/php-fpm --nodaemonize --fpm-config /opt/php8/etc/php-fpm.conf
9. ExecReload=/bin/kill -USR2 $MAINPID
10. [Install]
11. 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

1. [opcache]
2. zend_extension=opcache.so
3. opcache.enable=1
4. opcache.jit_buffer_size=100M
5. opcache.jit=1255

启动

1. systemctl start php8.0-fpm

laravel

创建一个laravel项目【推荐：laravel视频教程】

1. cd /opt/web
2. 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

1. server {
2. listen 94;
3. access_log /tmp/test94.log main;
4. root /opt/web/php8/public;
5. index index.php index.html index.htm;
6. location / {
7. try_files $uri $uri/ /index.php?$query_string;
8. }
9. location ~ \.php {
10. fastcgi_pass unix:/run/php/php8.0-fpm.sock;
11. fastcgi_index /index.php;
12. include fastcgi_params;
13. fastcgi_split_path_info ^(.+\.php)(/.+)$;
14. fastcgi_param PATH_INFO $fastcgi_path_info;
15. fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
16. fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
17. }
18. }

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。

1. public function boot()
2. {
3. $this->configureRateLimiting();
4. $this->routes(function () {
5. Route::prefix('api')
6. ->middleware('api')
7. ->namespace('App\Http\Controllers\Api')
8. ->group(base_path('routes/api.php'));
9. Route::middleware('web')
10. ->namespace($this->namespace)
11. ->group(base_path('routes/web.php'));
12. });
13. }

其他一样，不用修改。

加个测试接口看看：

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

test接口查一条数据并返回

2. use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
3. public function test(Request $request)
4. {
5. return WareHouses::find(1)->toarray();
6. }}

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。

1. ab -n 100 -c 10

PHP7.3的测试结果如下：
