resin web server
This document describes how to install and run Resin "standalone" (without Apache or IIS). Resin provides a reliable, fast Web server which can also be used as a load balancer. In our benchmarks, it serves static pages faster than Apache. For most sites, Resin is ideal because of its performance, security and reliability.  Getting StartedThe following steps will start Resin for development:

Startup ScriptYou can create your own startup script which will start and stop the ResinWatchdog, and will pass any command-line arguments. The script might typically do a number of things:
The start script might look like: Example start.sh script
#!/bin/sh
JAVA_HOME=/usr/java
RESIN_HOME=/usr/local/share/resin
RESIN_ROOT=/var/www
java=$JAVA_HOME/bin/java
export JAVA_HOME
export RESIN_HOME
export RESIN_ROOT
$java -jar $RESIN_HOME/lib/resin.jar \
-resin-root $RESIN_ROOT \
-conf /etc/conf/resin.conf \
-server a \
$*
This script would be called as The More information on deploying on Unix is available on the Linux boot documentation. Getting Started

To install the service, use C:\> resin-3.1.x\httpd -install -conf conf/myconf.conf To remove the service, use C:\> resin-3.1.x\httpd -remove You will either need to reboot the machine or start the service from the Control Panel/Services panel to start the server. On a machine reboot, Windows will automatically start the web server. You can also start and stop the service from the command-line: C:\> net start resin ... C:\> net stop resin Resin's saves the command-line arguments and starts the service with those arguments. You can look view them in the control panel, under the executable string. With multiple named servers, you can use to specify the service name.
C:\> resin-3.1.x\httpd -install-as ResinA \
-conf conf/myconf.conf \
-server a
C:\> net start ResinA
Processes OverviewResin runs as multiple processes that begin with the following JVM command:
unix> java -jar /usr/local/share/resin/lib/resin.jar \
-conf /etc/resin/resin.conf \
start
The argument tells java to run the Main-Class defined in resin.jar's manifest. The argument specifies the path to your Resin configuration file. Lastly, Resin accepts , , and arguments which are passed to the watchdog process. An additional command-line option, is used in load-balanced deployments. JDK 1.5 includes a jps command which will show the pids of any java processes. Example jps Process List unix> jps 2098 Jps 2064 ResinWatchdogManager 2097 Resin When running as a daemon (eg, The first process that starts is the actual startup program,
 The Watchdog ProcessThe ResinWatchdogManager is the parent process, providing automatic restarting Resin in cases of failure, and providing a single point of control for the , and of all Resin processes. It is responsible for launching Resin with the correct JVM arguments and environment options such as starting Resin as the specified user, e.g. for <user-name> on unix. ResinWatchdogManager watches Resin via a Socket connection. When the watchdog socket closes, Resin shuts itself down gracefully. The watchdog closes the socket on a or or if the watchdog itself is killed. If Resin exits for any reason, the watchdog will automatically start a new Resin process. This socket connection approach avoids the need for any signals or actual killing of Resin from the watchdog, and also makes it easy to stop all the Resins if necessary by just killing the watchdog. The ResinWatchdogManager doesn't actually kill Resin or even check Resin's status, it just checks to see if Resin is alive or not. So if the JVM were to completely lock up, the watchdog would still think Resin was okay and would take no action. Resin ProcessesIf Resin detects a major error (like running out of memory) or if the resin.conf changes, it will exit and the watchdog would start a new Resin instance. Reasons a Resin instance might exit include:
Because the watchdog is always managing Resin processes, if you ever need to stop Resin with , you must kill the watchdog. Just killing the Resin process results in the watchdog restarting it automatically. LoggingThe watchdog will log to . The Resin standard out/err is . ResinWatchdogManager is responsible for creating both of these log files, so is not really under the control of the Resin instance. This makes it somewhat more reliable in case of JVM deadlocks, etc.
