调整配置

查看 php.ini 默认的装载目录

因为在编译阶段没有加入 --with-config-file-path=(path-to-ini-dir)，所以目录是源码默认的目录，加入这个参数在 ./configure 可以指定目录；这里可以通过命令来查找出装载的 ini 的位置，当然如果是 cli 模式也可以通过 -c 参数来指定本次执行装载的 php.ini 文件。

1
php -i | grep ini
1
Configuration File (php.ini) Path => /usr/local/php/lib

创建 ini 配置

拷贝一份源码目录下的 php.ini-production 到 etc 目录下

1
cp /opt/php74/php.ini-production /usr/local/php/etc/php.ini

软连接到默认目录

1
ln -s /usr/local/php/etc/php.ini /usr/local/php/lib/php.ini
