Centos-Thin Web server for Ruby (install thin in centos and run rails)

ArticleDirectory

• 1. Install thin
• 2. Start and Stop thin
• 3. Cluster
• 4. runlevels
• 5. Run rails

1. Install thin

 
Gem install thin
 

He will need some gem support.

 
Rack-0.9.1Eventmachine-0.12.6Daemons-1.0.10Thin-1.0.0
 

Of course, it will be installed automatically.

2. Start and Stop thin

Run the following command in the root directory of the rails project:

 
Thin start-d
 

Adding-D enables him to run in the background without adding it. When we stop thin, we can directly use Ctrl + C.

Append "-e production" to run in the production environment, append "-P 3003" to the specified port, and specify port 3003 here

 
Thin stop
 

Stop thin

3. Cluster

 
Thin start -- servers 3
 

 
Thin stop -- servers 3
 

4. runlevels

You can add thin to runlevel (/etc/init. d /)

 
Sudo thin install
 

Add scripts for the default runlevels

 
Sudo/sbin/chkconfig -- level 345 thin on
 

Note:

An error may occur here, indicating that thin cannot be found.

Run this command.

 
Sudo mV/etc/rc. d/thin/etc/rc. d/init. d/thin
 

Then run

 
Sudo/sbin/chkconfig -- level 345 thin on
 

You can.

View

 
Sudo/sbin/chkconfig -- list thin
 

Will display

 
Thin 0: off 1: off 2: On 3: On 4: On 5: on 6: Off
 

5. Run rails

Now let's define which rails project will run at the restart.

For example, our tails project is here

 
/Home/demo/public_html/testapp/
 

We want him to start in production mode under three thin' services when starting.

Sudo thin config-C/etc/thin/testapp. yml-C/home/demo/public_html/testapp/-- servers 3-e Production
 

Take a look at the generated/Etc/thin/testapp. yml File

 
CAT/etc/thin/testapp. yml
 

Display

 
PID: TMP/PIDs/Thin. pidlog: Log/Thin. logtimeout:30Port:3000Max_conns:1024Max_persistent_conns:512Environment: productionchdir:/Home/demo/public_html/Testapprequire: [] address:0.0.0.0Servers:3Daemonize:True
 

We can see that servers and environment are set. Of course, we can also add or modify other command parameters we want, such as the port number.

OK
