Yii and AWS: Configure Yii on EC2 AMI

First you need to install essential modules on AMI. If you like to use Nginx, please take a look at tutorial here. If you like Apache more, please see here.
I myself likes to use Nginx. However, by default AWS Nginx config does not contain sites-avaliable and sites-enabled folder. I recommend using sites-enable and available structure to keep things organized.

Configure Nginx

First we make two directories within nginx config.

cd /etc/nginx/
sudo mkdir sites-available
sudo mkdir sites-enabled

then we need to config nginx.conf, we construct a new config file.

sudo vim nginx.temp

Paste the following code into the file without modification.Refer to Yii official website.

worker_processes 4;
pid /var/run/nginx.pid;

events {
 worker_connections 768;
 # multi_accept on;
}

http {

 ##
 # Basic Settings
 ##

 sendfile on;
 tcp_nopush on;
 tcp_nodelay on;
 keepalive_timeout 65;
 types_hash_max_size 2048;
 # server_tokens off;

 # server_names_hash_bucket_size 64;
 # server_name_in_redirect off;

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

 ##
 # Logging Settings
 ##

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

 ##
 # Gzip Settings
 ##

 gzip on;
 gzip_disable "msie6";

 # gzip_vary on;
 # gzip_proxied any;
 # gzip_comp_level 6;
 # gzip_buffers 16 8k;
 # gzip_http_version 1.1;
 # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

 ##
 # nginx-naxsi config
 ##
 # Uncomment it if you installed nginx-naxsi
 ##

 #include /etc/nginx/naxsi_core.rules;

 ##
 # nginx-passenger config
 ##
 # Uncomment it if you installed nginx-passenger
 ##
 
 #passenger_root /usr;
 #passenger_ruby /usr/bin/ruby;

 ##
 # Virtual Host Configs
 ##

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


#mail {
# # See sample authentication script at:
# # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
# server {
#  listen     localhost:110;
#  protocol   pop3;
#  proxy      on;
# }
# 
# server {
#  listen     localhost:143;
#  protocol   imap;
#  proxy      on;
# }
#}

then we replace the config file

sudo mv nginx.temp nginx.conf

after that we edit a nginx server file, replace the with your own domain

sudo vim sites-avaliable/

copy and edit the server info to the file, replace the domain with your own domain info and the host_path and document to be the root of your hosted files.

server {
    set $host_path "/var/www/html/";
    set $document "/var/www/html/";
    server_name  "domain";

    #access_log  /var/log/nginx/access.log  main;

    root   $host_path;
    set $yii_bootstrap "index.php";
    charset utf-8;

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

    location ~ ^/(protected|framework|themes/\w+/views) {
        deny  all;
    }

    #avoid processing of calls to unexisting static files by yii
    location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
        try_files $uri =404;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php {
        fastcgi_split_path_info  ^(.+\.php)(.*)$;

        #let yii catch the calls to unexising PHP files
        set $fsn /$yii_bootstrap;
        if (-f $document$fastcgi_script_name){
            set $fsn $fastcgi_script_name;
        }

        fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME  $document$fsn;

        #PATH_INFO and PATH_TRANSLATED can be omitted, but RFC 3875 specifies them for CGI
        fastcgi_param  PATH_INFO        $fastcgi_path_info;
        fastcgi_param  PATH_TRANSLATED  $document$fsn;
    }

    location ~ /\.ht {
        deny  all;
    }
}

make a symbolic link from sites-enabled to sites-available, so even the file is deleted in sites-enabled, the file in sites-available is still there.

sudo ln -s sites-available/domain sites-enabled/domain

Make sure that you session was started automatically in /etc/php.ini config "session.auto_start = 1" or it was started manually by session_start() or Yii similar function

$session=new CHttpSession;
$session->open();

And check your session status by session_status() function. restart nginx and the server, everything will be fine.
