VPSTOOLBOX依赖篇–PHP-FPM

PHP-FPM是VPSTOOLBOX的基础依赖之一。

本文将展示从零开始自己搭建一个PHP-FPM伺服器 ，开启NGINX反向代理的方法，因此限于篇幅以及本人的知识水平，我会展示我所学会的，欢迎各位在评论区交流。

一。 前情提要

问一： 为什么用PHP-FPM ?

答： 因为有些软件是PHP写的(比如TT-rss,roundcube Webmail等)，需要这个。

问二： PHP-FPM有什么用 ?

答： 基础依赖罢了。

问三： PHP-FPM对新手友好吗？

答： 是的，安装和配置都不难。

二。 准备工作

准备工作很简单，有一台有独立公网ip的非中国大陆LINUX伺服器即可。

三。 开始搭建

  1. 连接伺服器，我不想教这个,SSH教程请自己搜。

  2. 我个人不使用Centos，因此本教程只涉及Debian/Ubuntu，想看Centos的可以关掉本页面了。

    安装依赖

    1
    apt-get install sudo gnupg2 ca-certificates lsb-release -y

    添加APT源，本文不涉及编译，故deb-src不需要。

    Debian

    1
    2
    3
    wget --no-check-certificate -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
       echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list
       apt-get update

    Ubuntu(我只在18.04上测试过,20.04请自己Google)

    1
    2
    add-apt-repository ppa:ondrej/php -y
       apt-get update

    安装PHP-FPM。

    1
    2
    3
    4
    5
    apt-get -y install php7.4
       systemctl disable --now apache2
       apt-get install php7.4-fpm -y
       apt-get install php7.4-common php7.4-mysql php7.4-ldap php7.4-xml php7.4-json php7.4-readline php7.4-xmlrpc php7.4-curl php7.4-gd php7.4-imagick php7.4-cli php7.4-dev php7.4-imap php7.4-mbstring php7.4-opcache php7.4-soap php7.4-zip php7.4-intl php7.4-bcmath -y
       apt-get purge apache2* -y

  3. 至此，安装完成，接下来我们需要配置PHP-FPM。

注：你确实可以直接apt install php-fpm，但这样的话就不会是最新版，因此我选择使用上述安装方法。

四。 配置PHP-FPM

  1. 配置PHP-FPM时区

    1
    sed -i "s/;date.timezone.*/date.timezone = UTC/" /etc/php/7.4/fpm/php.ini

  2. 安装PHP-composer

1
2
3
4
cd /etc/php/7.4/
curl -sS https://getcomposer.org/installer -o composer-setup.php
php composer-setup.php --install-dir=/usr/local/bin --filename=composer
cd
  1. 设置PHP-FPM运行用户以及权限，本文使用NGINX，故PHP-FPM以NGINX用户运行。

; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions. The owner
; and group can be specified either by name or by their numeric IDs.

  1. 重启PHP-FPM服务以重载配置文件
1
2
systemctl restart php7.4-fpm
systemctl enable php7.4-fpm

五。NGINX反向代理配置

1
sudo nano /etc/nginx/conf.d/default.conf

在需要PHP的location里面添加以下配置即可。

location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_pass   unix:/run/php/php7.4-fpm.sock;
        }

六。总结篇

現在，您已經安裝了PHP-FPM，您可以安装其他以PHP-FPM为依赖的软件了。
