1,查看配置的幫助:
[root@kubemaster php-8.0.0]# ./configure --help
php配置時參數時有變化，
不確定時可以查看這里給出的提示
2,配置

[root@kubemaster php-8.0.0]# dnf -y install libzip-devel
四，測試php8安裝是否成功:
[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，生成各個配置文件:
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，啟動php-fpm
1，生成php-fpm啟動文件
[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，啟動php-fpm
[root@kubemaster ~]# /usr/local/soft/php8/daemon/php-fpm start Starting php-fpm done
3, 查看進程中是否已啟動
[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默認守護的端口:
[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訪問php-fpm
1,准備測試用的目錄和代碼:
[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個虛擬主機,使可以訪問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; } }
然后重啟nginx
3，從瀏覽器訪問php
訪問:
http://127.0.0.1:8003/info.php
瀏覽器返回
可見php8已安裝成功
九，啟用php8的jit特性:
1,編輯php.ini
;啟用opcache
opcache.enable=1 opcache.enable_cli=1
;啟用jit,並指定jit的buffer
opcache.jit_buffer_size=128M opcache.jit=1255
;zend對opcache模塊的引用，要打開
zend_extension=opcache
說明：關於如何設置jit的配置值，可以參考鳥哥的這個文檔:
https://www.laruence.com/2020/06/27/5963.html
2,重啟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的變化：
需要能看到zend opcache一項，
否則opcache未生效
注意看JIT中的一項，需要值為On
opcache.jit的值也是我們所設置的值
4,用php代碼測試jit的狀態?
[root@kubemaster html]# more jit.php <?php var_dump(opcache_get_status()['jit']); ?>
訪問:
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兩項的值都為true,
則表示jit已開啟
十，查看linux的版本:
[root@kubemaster html]# cat /etc/redhat-release CentOS Linux release 8.2.2004 (Core)
