[root@localhost php-7.2.8]# make -j $(cat /proc/cpuinfo |grep processor |wc -l)
[root@localhost php-7.2.8]# make install
……过程略

//安装后配置
[root@localhost ~]# echo 'export PATH=/usr/local/php7/bin:$PATH' >/etc/profile.d/php7.sh
[root@localhost ~]# source /etc/profile.d/php7.sh
[root@localhost ~]# cd /usr/src/php-7.2.8
[root@localhost php-7.2.8]# which php

//配置php-fpm
[root@localhost php-7.2.8]# cp php.ini-production /etc/php.ini
[root@localhost php-7.2.8]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-7.2.8]# chmod +x /etc/rc.d/init.d/php-fpm

[root@localhost php-7.2.8]# cp /usr/local/php7/etc/php-fpm.d/www.conf.default  /usr/local/php7/etc/php-fpm.d/www.conf

//配置fpm的相关选项为你所需的值：
[root@localhost ~]# vim /usr/local/php7/etc/php-fpm.conf
*****在配置文件最后面添加一下内容
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8

//启动php-fpm
[root@localhost ~]# service php-fpm start
Starting php-fpm done
[root@localhost ~]# ss -antl

4.配置nginx与php测试

//nginx配置文件/usr/local/nginx/conf/nginx.conf
//只要修改配置文件中的server{ } 配置块中的内容，修改location块，追加index.php让nginx服务器默认支持index.php为首页
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf
…………………………………………
…………………………………………
server {
        listen 80;
        server_name localhost;
        #charset
        koi8-r;
        #access_log
        logs/host.access.log main;
        location / {
                root html;
                index index.html index.htm//后面添加 index.php;
        }
…… ……………………………………
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ ⧵.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
#主要修改的就是fastcgi_param中的/scripts为$document_root
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root

//修改配置文件后重新加载nginx
[root@localhost ~]# nginx  -s  reload

//创建测试php程序，在/usr/local/nginx/html/index.php,打印一下php配置
[root@localhost ~]# cat > /usr/local/nginx/html/index.php << EOF
>  phpinfo();
> ?>
> EOF

最后打开浏览器输入 192.168.206.129/index.php 看到输出的页面，说明nginx和php都配置
成功了
