We are in 2015 but we still have problems with blogging, at least I have problems. What I am looking for:
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( array( 'host' => Rediska_Connection::DEFAULT_HOST, 'port' => Rediska_Connection::DEFAULT_PORT, 'weight' => Rediska_Connection::DEFAULT_WEIGHT, 'db'=>2, 'persistent'=>TRUE, 'timeout'=>0 ) ) ); $redis = new Rediska($options);
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:
CentOS [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1
To install php 5.3.8 we need extra repos (source article).
## Remi Dependency on CentOS 5 and Red Hat (RHEL) 5 ## rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm ## CentOS 5 and Red Hat (RHEL) 5 ## rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
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
Start PHP-FPM
/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 { server_name example.net; 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_pass 127.0.0.1:9000; 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(); ?>
