php displays blank page despite error reporting = On
Posted: Thu Nov 11, 2010 9:14 am
I had a Wordpress site on a Debian VPS, it was working fine with Apache and PHP, except that Apache kept on running out of RAM and getting killed. So I switched to nginx instead. NGInx requires something called php5-fpm to work with PHP. So I installed it, and it ran. But every php page now shows up completely blank. /var/log/php5-fpm.log shows nothing interesting, even when set to debug level logging. I made sure to tell NGInx to pass PHP to 127.0.0.1:9000 too:
/etc/nginx/sites-available/default
Looks OK, right? I then saw that PHP blank pages mean you need to set error reporting = On in php.ini, which is fine except that in /etc/php5, there are this many php.ini files:
I set display_errors = On in fpm/php.ini, and in cli/php.ini, and in cgi/php.ini. Then I restarted php5-fpm. Still a blank page. Not even a simple <?php phpinfo(); ?> page works. What should I do?
/etc/nginx/sites-available/default
Code: Select all
server {
listen 80;
server_name localhost;
access_log /var/log/nginx/localhost.access.log;
location / {
root /var/www;
index index.php index.html index.htm;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
#proxy_pass http://127.0.0.1;
#}
#pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
