9、修改配置文件
# 查看当前配置文件
[root@*-*-*-* ~]# /usr/local/php8/bin/php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php8/etc
# 查看源文件中的ini配置文件
[root@*-*-*-* ~]# ll /software/php-8.0.17 | grep ini
-rw-rw-r--. 1 root root 72384 Mar 15 16:24 php.ini-development
-rw-rw-r--. 1 root root 72530 Mar 15 16:24 php.ini-production
# 复制php.ini 配置文件
[root@*-*-*-* php-8.0.17]# cp /software/php-8.0.17/php.ini-production /usr/local/php8/etc/php.ini
# 创建php、php-fpm软连接
ln -s /usr/local/php8/bin/php /usr/local/bin/php
ln -s /usr/local/php8/sbin/php-fpm /usr/local/bin/php-fpm
10、启动php-fpm服务
[root@10-60-71-116 php-8.0.17]# cd /usr/local/php8/etc/
[root@10-60-71-116 etc]# cp php-fpm.conf.default php-fpm.conf
[root@10-60-71-116 etc]# cp php-fpm.d/www.conf.default php-fpm.d/www.conf
