Static Blog

We are in 2015 but we still have problems with blogging, at least I have problems. What I am looking for:

  • Simple WYSIWYG editor to write posts
  • Simple GUI to manage current posts
  • Different themes to select or at least easily customize a theme
  • To get static html version of whole blog
  • Html version should work seamless in a simple server (no PHP, or database support required)
  • A bonus feature, automatically update web site when I change local version (auto export and deploy)

Rediska Instance Problem

I am building a task module, to do time consuming jobs in background. A worker instance is constantly pooling redis db for a new task. However after first connection, somehow rediska (a php redis client) closes connection, and when I make query to db, it automatically creates a new connection using default settings. At this point new connection is not using the settings in the configuration. It is using hard coded default values. I don’t know why it is doing this but here is the solution.

Whenever you use a rediska key, explicitly tell the instance name you want to use.
$option = array("rediska"=>"use_this_instance_name");
$pointer = new Rediska_Key("job:$index:pointer",$option);

To define aforementioned rediska instance:

$options = array (
                    'addToManager' => true,
                    'name'         => "use_this_instance_name",
                    'namespace'    => '',
                    'servers'      => array(
                            'host'   => Rediska_Connection::DEFAULT_HOST,
                            'port'   => Rediska_Connection::DEFAULT_PORT,
                            'weight' => Rediska_Connection::DEFAULT_WEIGHT,
$redis = new Rediska($options);

Nginx 1.010 + PHP 5.3.8 (on Centos 5.7)

Installing nginx is straightforward, so I will not go into details, just check the nginx documentation for more.

First create a repo file.

vi /etc/yum.repos.d/nginx.repo

and add following content to repo file:

name=nginx repo

To install php 5.3.8 we need extra repos (source article).

## Remi Dependency on CentOS 5 and Red Hat (RHEL) 5 ##
rpm -Uvh
## CentOS 5 and Red Hat (RHEL) 5 ## 
rpm -Uvh

Install using added repos.

yum --enablerepo=remi install nginx php php-fpm php-common

Install necessary php modules for you.

yum --enablerepo=remi install php-pear

Start Nginx

/etc/init.d/nginx start ## use restart after update
## OR ##
service nginx start ## use restart after update


/etc/init.d/php-fpm start ## use restart after update
## OR ##
service php-fpm start ## use restart after update

Autostart Nginx on boot

chkconfig --add nginx
chkconfig --levels 235 nginx on
#Autostart PHP-FPM on boot
chkconfig --add php-fpm
chkconfig --levels 235 php-fpm on

Now it is time to configure nginx to work with php.

vi /etc/nginx/conf.d/test.conf

put these lines into file.

server {
    access_log /var/logs/nginx/example.access.log;
    error_log /var/logs/nginx/example.error.log;
    root /var/www/example;
    location / {
        index index.html index.htm index.php;
    location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /var/www/example$fastcgi_script_name;

restart nginx

service nginx restart

create an index file to test.

vi /var/www/example/index.php
<?php phpinfo(); ?>
