文章是记录自己安装的一个过程，其中的配置完全是个人的需求。

sudo apt-get install gcc autoconf curl libxml2 libxml2-dev libssl-dev bzip2 libbz2-dev libjpeg-dev libpng12-dev libfreetype6-dev libgmp-dev libmcrypt-dev libreadline6-dev libsnmp-dev libxslt1-dev libcurl4-openssl-dev libonig-dev libzip-dev

这是必须的，因为编译前的配置需要它们的支持。

sudo groupadd -r php
sudo useradd -r -g php -s /bin/false -d /usr/local/php7 -M php

下载并解压PHP源码
截至到目前，php的最新稳定版本为php-8.0.8，那么就用它了。
选择一个合适的节点源码文件下载,并进行解压操作
wget http://am1.php.net/distributions/php-7.2.0.tar.xz
xz -d php-7.2.0.tar.xz
tar -xvf php-7.2.0.tar

tar -Jxvf php-8.0.8.tar.xz
cd php-8.0.8

排错
由于环境变量问题，配置过程会出现如下报错信息
configure: error: Cannot find OpenSSL's libraries
openssl version 可以看到 OpenSSL 1.0.2g 1 Mar 2016
解决方法，找到libssl.so软链接到/usr/lib下：
1
2
|
sudo find / -name libssl.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib
|
当然我的排错过程远不止这么简单，如果你按照我的第一个步骤做了，那么仅仅只要做这个操作。
配置PHP
配置PHP_HOME
在最底下一行的上面添加如下内容:
1
2
3
|
#set for PHP
export PHP_HOME=/usr/local/php7
export PATH=$PHP_HOME/bin:$PATH
|
保存并退出，编译/etc/profile 使配置生效
增加 php-fpm 命令：
1
2
|
cp sapi/fpm/init.d.php-fpm /usr/local/bin/php-fpm
chmod +x /usr/local/bin/php-fpm
|
1
2
|
cp php.ini-production /usr/local/php7/etc/php.ini
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
|
当然了，为了更精简以及后续的修改方便php-fpm.conf也可以直接使用下面的方式配置

找到Nginx配置文件的 fastcgi_pass
将 unix:/run/php/php7.0-fpm.sock; 改为 php-fpm进程池的监听地址unix:/usr/local/php7/var/run/www-php-fpm.sock;

设置开机自动启动 PHP-FPM
1

|
cp sapi/fpm/php-fpm.service /etc/systemd/system/
chmod +x /etc/systemd/system/php-fpm.service

保存以后，设置开机自启以及开启服务：

|
systemctl enable php-fpm.service
systemctl start php-fpm.service

好了！终于填坑完成了！
