一、下载
(资料图片仅供参考)
1、https://www.php.net/distributions/php-8.0.0.tar.gz下载到本地，文件传输上传到 /usr/local/src/
2、wget -P /usr/local/src/ https://www.php.net/distributions/php-8.0.0.tar.gz
二、解压、编译、安装
1、解压缩
> cd /usr/local/src/> tar xzf php-8.0.0.tar.gz> cd php-8.0.0

登录后复制3、编译源码
> make -j2 # 这里是依赖系统cpu核心数进行编译，对性能有一定提升，通常利用核心数不要超过一半，
4、安装
make install
登录后复制安装成功

登录后复制6、获取默认配置
// 复制php.ini到编译配置参数指定的目录。php.ini在解压的源码目录里> cp /usr/local/src/php-8.0.0/php.ini-production /usr/local/php8/etc/php.ini// 复制一份php-fpm的配置模版文件到同级目录 方便备份和修改> cp /usr/local/php8/etc/php-fpm.conf.default /usr/local/php8/etc/php-fpm.conf// 复制一份php-fpm的扩展配置模板文件到同级目录 方便备份和修改> cp /usr/local/php8/etc/php-fpm.d/www.conf.default /usr/local/php8/etc/php-fpm.d/www.conf// 复制开启自起脚本到系统启动自动加载脚本目录。fpm/init.d.php-fpm在解压的源码目录里> cp /usr/local/src/php-8.0.0/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
登录后复制7、开机自启动
设置命令可被执行
> chmod +x /etc/init.d/php-fpm # 添加可执行权限
登录后复制检验自启动脚本
> service php-fpm start # 检验服务启动> service php-fpm stop # 检验服务关闭// 均正常提示> chkconfig php-fpm on # 设置开机自动执行php-fpm开机自启动脚本> reboot # 重启，ssh重连# 重启后[root@54skyer ~]# netstat -ntlpActive Internet connections (only servers)Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1097/nginx: master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1061/sshd tcp 0 0 0.0.0.0:16379 0.0.0.0:* LISTEN 1090/redis-server 0 tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 1083/php-fpm: maste
登录后复制7、额外说明
关于配置文件的一些说明
php-fpm.conf是PHP-FPM特有的配置文件
php.ini是所有php模式中必须的配置文件
两者的区别是，php-fpm.conf是PHP-FPM进程管理器的配置文件，php.ini是PHP解析器的配置文件
有的PHP版本的配置文件路径中还有/fpm.d/www.conf配置文件
这是php-fpm.conf配置的文件的扩展文件，可以打开php-fpm.conf文件查看
; include=fpm.d/*.conf
登录后复制我们可以使用php-fpm.conf配置慢日志
我们是可以开启慢日志功能的。
slowlog = /usr/local/var/log/php-fpm.log.slowrequest_slowlog_timeout = 5s
