goal
----

The goal is send syslog traffic to a remote host and use unpriviledged ports;
so that I can have my logstash (http://logstash.net/) server not need to
run as root. On vSphere 5.1, tcp 1514 is covered by the syslog rule, but
in my case udp is preferred.

installation
------------

dnozay

install the packages

# yum install php-fpm php-ldap

then make sure php-fpm can create sessions
and change user and group to be nginx
see /etc/php-fpm.d/www.conf for more details

# sed -i -e 's/apache/nginx/g'  /etc/php-fpm.d/www.conf
# sed -i -e 's/;catch_workers_output = yes/catch_workers_output = yes/'  /etc/php-fpm.d/www.conf
