Nginx CodeIgniter not working - mysql

Question

I am new to nginx. I am transfering my server from apache to nginx but my many projects on the CodeIgniter core PHP sites working perfectly but the CodeIgniter is not work.
My sample url like this:
http://example.com/track/
this is redirect to:
http://example.com/track/index.php/sessions/login
but it returns 404 Not Found.
my server configure like this:
server {
listen 80;
server_name 192.168.0.80;
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}
my error log file like this

What's wrong? I did a search in google but not working perfectly.

Answer 1

Check out this link, should fix your rewriting issues.
If you have further questions you can ask.
Code igniter for nginx
Edit:
Ok so there's several ways to fix your case, but I'll describe the closest to your case
If you're going to edit in the same file as nginx conf as how I think you're doing right now then try adding this
location /track {
try_files $uri $uri/ /track/index.php;
}
Not sure if the routing needs $request_uri appended to index.php or not.
And i think you should configure CodeIgniter to be aware of this sub folder
$config['base_url'] = "192.168.0.80/track"
This isn't really the cleanest way to do this configuration, I'd prefer adding a domain name in the /etc/hosts and create a new separate server in nginx.

Answer 2

I ran into a similar problem earlier today: the code igniter URI routing requires that both the REQUEST_URI and the SCRIPT_NAME variables be defined. Many of the Nginx/PHP-FPM guides don't define the SCRIPT_NAME variable, so you end up with routing failures. You'll need to add a line that looks like this:
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
and then you can use REQUEST_URI in your config.php file and the routing should work.
