四,测试php8安装是否成功:

[root@kubemaster php-8.0.0]# /usr/local/soft/php8/bin/php --version
PHP 8.0.0 (cli) (built: Nov 27 2020 14:34:26) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies

 

五,生成各个配置文件:

1,生成php.ini配置文件:
[root@kubemaster php-8.0.0]# cp php.ini-production /usr/local/soft/php8/etc/php.ini

 

2,生成www.conf配置文件
[root@kubemaster php-8.0.0]# cd /usr/local/soft/php8/etc/php-fpm.d/
[root@kubemaster php-fpm.d]# cp www.conf.default www.conf

 

3,生成php-fpm的配置文件
[root@kubemaster php-fpm.d]# cd /usr/local/soft/php8/etc/
[root@kubemaster etc]# cp php-fpm.conf.default php-fpm.conf

 

六,启动php-fpm

1,生成php-fpm启动文件
[root@kubemaster ~]# mkdir /usr/local/soft/php8/daemon
[root@kubemaster ~]# cp /usr/local/source/php-8.0.0/sapi/fpm/init.d.php-fpm /usr/local/soft/php8/daemon/php-fpm
[root@kubemaster ~]# chmod 740 /usr/local/soft/php8/daemon/php-fpm

 

2,启动php-fpm
[root@kubemaster ~]# /usr/local/soft/php8/daemon/php-fpm start
Starting php-fpm  done

 

3, 查看进程中是否已启动
[root@kubemaster ~]# ps auxfww | grep php | grep -v grep
root      218090  0.0  0.2 190036  9092 ?        Ss   14:49   0:00  \_ php-fpm: master process (/usr/local/soft/php8/etc/php-fpm.conf)
nobody    218091  0.0  0.2 214168  9664 ?        S    14:49   0:00      \_ php-fpm: pool www
nobody    218092  0.0  0.2 214168  9664 ?        S    14:49   0:00      \_ php-fpm: pool www

 

4,查看php-fpm默认守护的端口:
[root@kubemaster html]# ss -lntp | grep php
LISTEN  0   128     127.0.0.1:9000  0.0.0.0:*   users:(("php-fpm",pid=218092,fd=5),("php-fpm",pid=218091,fd=5),("php-fpm",pid=218090,fd=10))
可以看到是9000
 

七,配置nginx访问php-fpm

1,准备测试用的目录和代码:
[root@kubemaster web]# mkdir /data/web/phpweb
[root@kubemaster web]# mkdir /data/web/phpweb/html
[root@kubemaster web]# cd /data/web/phpweb/html
[root@kubemaster html]# vi info.php
[root@kubemaster html]# more info.php
<?php
phpinfo();
?>
 
2,配置nginx
   在nginx的配置文件中增加一个虚拟主机,使可以访问php
   demo如下:
      server {
        listen       8003;
        root   /data/web/phpweb/html;
 
        location ~ \.php {
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include        fastcgi_params;
        }
    }
    然后重启nginx
 
  3,从浏览器访问php
访问:
http://127.0.0.1:8003/info.php

浏览器返回 

可见php8已安装成功
 

九,启用php8的jit特性:

1,编辑php.ini
;启用opcache
opcache.enable=1
opcache.enable_cli=1

 

;启用jit,并指定jit的buffer
opcache.jit_buffer_size=128M
opcache.jit=1255

 

;zend对opcache模块的引用,要打开
zend_extension=opcache

 

说明:关于如何设置jit的配置值,可以参考鸟哥的这个文档:
https://www.laruence.com/2020/06/27/5963.html

 

2,重启php-fpm的daemon:
[root@kubemaster html]# /usr/local/soft/php8/daemon/php-fpm stop
Gracefully shutting down php-fpm . done
[root@kubemaster html]# /usr/local/soft/php8/daemon/php-fpm start
Starting php-fpm  done

 

3,查看phpinfo的变化:
需要能看到zend opcache一项,
否则opcache未生效
注意看JIT中的一项,需要值为On
 
opcache.jit的值也是我们所设置的值

 

 

 
4,用php代码测试jit的状态?
  [root@kubemaster html]# more jit.php
<?php
var_dump(opcache_get_status()['jit']);
?>

访问:

http://127.0.0.1:8003/jit.php
返回:
array(7) {
  ["enabled"]=>
  bool(true)
  ["on"]=>
  bool(true)
  ["kind"]=>
  int(5)
  ["opt_level"]=>
  int(5)
  ["opt_flags"]=>
  int(6)
  ["buffer_size"]=>
  int(104857584)
  ["buffer_free"]=>
  int(104855312)
}
 
注意:如果enabled和on两项的值都为true,
           则表示jit已开启
 

十,查看linux的版本:

[root@kubemaster html]# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
