php8.0.0安装体验和扩展介绍流程

php8.0

在这里插入图片描述

  • 安装前的扯犊子科普工作

PHP 三大模块：

  • SAPI：接受并处理请求。
  • Zend Engine：PHP 的核心，负责分析 PHP 代码并转为 opcode，然后在 Zend VM 虚拟机上执行。
  • PHP 功能函数及扩展层：实现各种功能，例如 curl 通信、连接 MySQL 等。

PHP 中，有以下几种方式添加扩展：

  • 把扩展编译进 PHP

  • 通过 pecl 命令或 Linux 发行版自带的 yum、apt-get 等命令安装，动态加载（Linux 下是 *.so 文件，Windows 下是 *.dll 文件）

  • 用 phpize 从源码编译共享 PECL 扩展库
    相比通过 yum install 或 apt-get 等各大 Linux 发行版自带的安装方向，源码编译安装略显复杂，但是灵活性也更高，比如要安装 PCNTL 等扩展，就只能通过源码编译安装。

  • 注意：源码编译安装时，只会安装指定的扩展，而好多扩展是默认不安装的。对于常用的数据库驱动、OpenSSL、GD 库等都需要指定。如果安装后发现遗漏，可以重新编译，加上相应的参数可得到驱动程序（Linux 下是 *.so 文件），然后复制到 PHP 的扩展目录（一般是 /usr/local/php/include/php/ext）下，并在 php.ini 配置文件中开启扩展既可以。

通过 yum list php72w-* 可以在 CentOS 中查看可以使用命令安装的扩展。

  • 概述啰嗦完成，接着来干正事

安装环境

  • 1核2GB配置，建议玩家能高就高，下文就有编译过程中低配置的问题体现，仔细阅读，谨慎跳跃查看
CentOS Linux release 7.7.1908 (Core)

Linux VM_0_12_centos 3.10.0-1062.9.1.el7.x86_64 #1 SMP Fri Dec 6 15:49:49 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

0、下载地址

wget https://github.com/php/php-src/archive/php-8.0.0.tar.gz

  • 1

安装依赖

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

1、压缩包解压常规操作 php-src-php-8.0.0.tar.gz

tar -zxvf php-src-php-8.0.0.tar.gz

  • 1

2、从官方包中拿到的数据不含configure脚本,需要将安装GNU autoconf,来生成configure


yum install autoconf
运行 ./buildconf
``

然后 configure就可以安装了
参考官网地址：https://www.php.net/manual/zh/faq.build.php

3、调用configure生成Makefile文件

执行配置选项（例如 --prefix 可以指定安装位置），判断硬件及操作系统平台，生成需要编译的 Makefile 文件

执行configure的前置操作

mkdir /usr/local/php800

配置扩展参数

./configure \

错误清单

(1)configure: error: re2c 0.13.4 is required to generate PHP lexers.

需要安装re2c

yum安装rpm包
yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/r/re2c-0.14.3-2.el7.x86_64.rpm

./configure && make && make install

安装（git源码编译）
git clone https://git.code.sf.net/p/re2c/code-git re2c && cd re2c/
./autogen.sh && ./configure --prefix=/usr/local/re2c/
make && make install
ln -sf /usr/local/re2c/bin/re2c /usr/local/bin/re2c
re2c -v
re2c -h
git clone https://github.com/skvadrik/re2c.git re2c && cd re2c

(2)测试安装 php 的 openssl 模块的时候，分别使用了以下方式(以具体的openssl扩展为例)
./configure
./configure --with-openssl
./configure --with-openssl=/usr/local
./configure --with-openssl=/usr/local/xxx

结果出现了不同的结果

第一种不会安装 openssl 模块
第二种可以正常安装 openssl 模块
第三种可以正常安装 openssl 模块 (我的电脑存在 /usr/local/include/openssl/evp.h)
第四种会报错：configure: error: Cannot find OpenSSL's evp.h (我的电脑 /usr/local/xxx 是空目录)

4、编译和安装

make && make install

  • 1

错误提示

1、make: *** [ext/fileinfo/libmagic/apprentice.lo] Error 1

因为系统的内存不足1G造成的,然后需要加上 --disable-fileinfo,然重新编译即可；

即在执行 ./configure 时–enable-fileinfo 改为 --disable-fileinfo

清除原编译 make clean，重新生成makefile文件

成功make提示

Build complete.
Don't forget to run 'make test'.

php8一些配置

配置php.ini

进行到php8的源代码根目录中操作（编译过程中制定了位置）：

cp php.ini-production /usr/local/php800/etc/php.ini


  • 1
  • 2

配置环境变量


ln -s /usr/local/php800 /usr/bin/php8

或者添加 /etc/profile 进行配置，在末尾追加如下记录：

# PHP8
export PATH=$PATH:/usr/local/php800/bin


  • 1
  • 2
  • 3

source /etc/profile 生效

配置php-fpm

配置下如下环境，可以修改监听的端口等

cd /usr/local/php800/etc
cp php-fpm.conf.default php-fpm.conf

cd /usr/local/php800/php-fpm.d
cp www.conf.default www.conf

重启php-fpm即可生效

[global]
; Pid file
; Note: the default prefix is /usr/local/php800/var
; Default Value: none
pid = run/php-fpm800.pid

init.d的php-fpm服务的添加（跟systemd配置一个即可，php738采用此法启动）

/etc/init.d 是 /etc/rc.d/init.d 的软链接

php源码编译目录下的 sapi/fpm/init.d.php-fpm 文件拷贝到系统配置 /etc/init.d 目录下并重命名为 php-fpm

cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm 
chmod +x /etc/init.d/php-fpm

# 启动命令
service php-fpm start
service php-fpm stop
service php-fpm restart
service php-fpm reload
 或
/etc/init.d/php-fpm start
/etc/init.d/php-fpm stop
/etc/init.d/php-fpm restart
/etc/init.d/php-fpm reload

配置一下.env文件

nginx配置

        fastcgi_index /index.php;

        include fastcgi_params;

        fastcgi_split_path_info       ^(.+\.php)(/.+)$;

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

        $this->routes(function () {

                ->middleware('api')
                ->namespace('App\Http\Controllers\Api')

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

<?php

namespace 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。

先测试php8的ab结果

ab -n 100 -c 10 http://php8.humengxu.com/api/test
