操作系统：CentOS7
安装版本：PHP7.4
【官网】https://www.php.net/downloads
1）到PHP官网下载PHP7.4，并且解压
cd /home/install/php
wget https://www.php.net/distributions/php-7.4.12.tar.gz
tar -zxvf php-7.4.12.tar.gz

到这里没有报错过一会会出现下图界面

然后再执行编译安装命令（编译安装过程时间有些长，须耐心等待）

make install

You may want to add: /usr/local/php/lib/php to your php.ini include_path
/home/install/php/php-7.4.12/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin/phar.phar
ln -s -f phar.phar /usr/local/php/bin/phar
Installing PDO headers: /usr/local/php/include/php/ext/pdo/
3）以上终于完成PHP的源码编译安装了，下面就是配置PHP
# 配置PHP
[root@localhost php-7.4.12]# php -v
bash: php: 未找到命令...
[root@localhost php-7.4.12]# /usr/local/php/bin/php -v
PHP 7.4.12 (cli) (built: Nov 16 2020 19:43:47) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
为PHP添加环境变量
export PATH=$PATH:/usr/local/php/bin
php -v 直接就能查看php版本，不需要再 /usr/local/php/bin/php -v 这么长了
[root@localhost php-7.4.12]# php -v
PHP 7.4.12 (cli) (built: Nov 16 2020 19:43:47) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
4）配置PHP-fpm，（请注意我的目录，是一直在PHP7的解压目录下操作命令）
/home/install/php/php-7.4.12/ 是我下载PHP包解压出来的目录
/usr/local/php/ 是PHP编译安装的目录
3.png
开始配置PHP-fpm，复制一些配置文件，做好备份准备
[root@localhost php-7.4.12] cp php.ini-development /etc/php.ini
[root@localhost php-7.4.12] cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-7.4.12] cd /usr/local/php/etc
[root@localhost etc] cp php-fpm.conf.default php-fpm.conf
[root@localhost etc] cp php-fpm.d/www.conf.default php-fpm.d/www.conf
[root@localhost etc]chmod +x /etc/init.d/php-fpm
# /etc/init.d/php-fpm文件的内容，确保正确
prefix=/usr/local/php
exec_prefix=${prefix}
php_fpm_BIN=${exec_prefix}/sbin/php-fpm
php_fpm_CONF=${prefix}/etc/php-fpm.conf
php_fpm_PID=${prefix}/var/run/php-fpm.pid
这时候就开始启动php-fpm了
# service php-fpm {start|stop|force-quit|restart|reload|status|configtest}
service php-fpm start #启动命令
ps ax|grep php-fpm # 查看是否启动php-fpm
[root@localhost etc] ps ax | grep php-fpm # 或者 netstat -ant | grep 9000
33891 ? Ss 0:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
33892 ? S 0:00 php-fpm: pool www
33893 ? S 0:00 php-fpm: pool www
34443 pts/0 S+ 0:00 grep --color=auto php-fpm
终于完成了......
最后补个小tips
假如在编译配置里加入这两个配置而导致启动失败
--with-fpm-user=nginx
--with-fpm-group=nginx
如果启动php-fpm失败，则需要在安装完之后的目录 /usr/local/php/etc/php-fpm.d/www.conf（配置完后的文件）
找到user和group修改他们的值为 nobody 就可以启动成功了
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user = nobody
group = nobody
