linux中如何通过php.ini添加扩展？

Question

在编译安装的时候，我只通过了以下命令来安装，然后我想像windows中那样修改 php.ini 就开启了扩展 ./configure \ --enable-fpm \ --with-fpm-user=www-data \ --with-fpm-group=www-data \ --enable-soap \ --enable-mysqlnd \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd $ make && make install 拷贝下载的php-7.2.6文件中的扩展文件 cp -r /opt/downloads/php-7.2.6/ext /usr/local/lib/ 然后去修改完 php.ini 文件，开启了以下扩展 extension_dir = "/usr/local/lib/etc" extension=bz2 extension=curl ;extension=fileinfo extension=gd2 extension=gettext ;extension=gmp ;extension=intl ;extension=imap ;extension=interbase ;extension=ldap extension=mbstring ;extension=exif ; Must be after mbstring as it depends on it extension=mysqli ;extension=oci8_12c ; Use with Oracle Database 12c Instant Client extension=odbc extension=openssl extension=pdo_firebird extension=pdo_mysql extension=pdo_oci extension=pdo_odbc; extension=pdo_pgsql; extension=pdo_sqlite extension=pgsql ;extension=shmop 运行报错 php-fpm -t [25-May-2018 08:24:59] NOTICE: PHP message: PHP Warning: PHP Startup:
