Php codeigniter在nginx（在本地主机上运行）中不工作，linux mint

我已经在linux mint系统上安装了LEMP。 nginx配置为与php5 fpm套接字一起使用。 当我在系统index.php（link:localhost/ci/index.php）中运行codeigniter时，会显示，但当我尝试打开任何控制器时，比如blog（link localhost/ci/index.php/blog），nginx会给出404错误消息

以下是我在/etc/nginx/sites available/default文件中的nginx配置

server {
listen 127.0.0.1:80;
listen [::]:80 default_server ipv6only=on;
root /home/scoders/Workspace/public_html;
index index.html index.htm index.php;
autoindex on;

server_name localhost;

location / {
    try_files $uri $uri/ /index.php?$args;
}

# Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests

location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(.*)$;
    fastcgi_param REQUEST_URI $request_uri;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME /home/scoders/Workspace/public_html/ci/index.php;
    #fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

}

nginx.conf的内容如下：

user scoders;
worker_processes 4;
pid /run/nginx.pid;

events {
    worker_connections 768;
}
http {
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;
    gzip_disable "msie6";

    xml+rss text/javascript;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
    include /etc/nginx/sites-enabled/*.conf;
    server_names_hash_bucket_size 64;
}

我的日志显示以下错误：

    2016/03/14 14:38:38 [error] 23239#0: *1 FastCGI sent in stderr: 
"Primary script unknown" while reading response header from upstream, 
client: 127.0.0.1, server: localhost, request: "GET /ci/index.php/ci 
HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "localhost"

我尝试了这些链接，但没有成功：

由于某种原因，

/home/scoders/Workspace/public_html/ci/index.php

无法访问，或者在

include fastcgi_参数中覆盖了
脚本文件名

一般来说，您应该在
之前包含
，在
fastcgi_param
之后包含

例如：

location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    include fastcgi_params;
    fastcgi_param REQUEST_URI $request_uri;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

另外，如果默认URI是
/ci/index.php
而不是
/index.php
，请将
位置/
更改为：

location / {
    try_files $uri $uri/ /ci/index.php?$args;
}

是blog.php或blog.php的文件名，应该是大写的第一个字母。控制器名是blog.phpjust prepending/ci to/index.php？$args它工作了，尽管我已经做了这两个更改。谢谢
