FreeBSD 12 下

apache 2.4
ee /usr/local/etc/apache24/httpd.conf
<Directory />
…
AllowOverride None 改为 AllowOverride All
…
</Directory>
重启 apachectl restart

如果 .htaccess
php_flag display_errors on
报500错误了，查看apache的error_log找到了如下的错误信息：
.htaccess: Invalid command ‘php_flag’, perhaps misspelled or defined by a module not included in the server configuration
是suPHP的问题，写另外一个文件”.user.ini”
error_reporting = E_ALL
display_errors = On
更改过”.user.ini”要重启php-fpm生效
#/usr/local/etc/rc.d/php-fpm restart

https://www.php.net/manual/zh/configuration.file.per-user.php

# cd /usr/ports/graphics/pear-Image_Barcode && make install clean

<?php
require_once('Image/Barcode.php');
Image_Barcode::draw('RR651943036CN', 'Code39', 'gif');
exit;
?>

FreeBSD 7.0-RELEASE-i386 + PHP5 + Apache2.2

# cd /usr/ports/net/pecl-geoip && make install clean
# apachectl restart
# cd ~
# fetch http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz
# gunzip GeoIP.dat.gz
# mv GeoIP.dat /usr/local/share/GeoIP/GeoIP.dat
# fetch http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
# gunzip GeoLiteCity.dat.gz
# mv GeoLiteCity.dat /usr/local/share/GeoIP/GeoIPCity.dat

<?php
echo geoip_database_info(GEOIP_COUNTRY_EDITION);

$country = geoip_record_by_name('wangblog.org');
if($country){
	echo "\nThis host is located in: \n";
	print_r($country);
}
?>

可以写个定时更新IP地址库的程序：

cd ~
/usr/bin/fetch http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz
/usr/bin/gunzip GeoIP.dat.gz
mv GeoIP.dat /usr/local/share/GeoIP/GeoIP.dat
/usr/bin/fetch http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
/usr/bin/gunzip GeoLiteCity.dat.gz
mv GeoLiteCity.dat /usr/local/share/GeoIP/GeoIPCity.dat

以上保存为：update-ipdata-cron.sh

crontab -e
添加以下一行，每月5日0点10分运行：
10 0 5 * * /bin/csh /path/to/update-ipdata-cron.sh
