I'm new with the PCF and trying to deploy a simple web-app. I've installed the cf CLI, pcfdev and pushed my app to pcf:
cf push test-ui -b staticfile_buildpack
...
name: test-ui
requested state: started
instances: 1/1
usage: 256M x 1 instances
routes: test-ui.local.pcfdev.io
last uploaded: Thu 23 Aug 13:09:04 +03 2018
stack: cflinuxfs2
buildpack: staticfile_buildpack
start command: $HOME/boot.sh
state since cpu memory disk details
#0 running 2018-08-23T10:09:17Z 0.0% 5.3M of 256M 25M of 512M
So, now, I can access my test app by link test-ui.local.pcfdev.io from the same machine where I've started my pcf instance. But I don't know how to access to this app from another device in the same network.
Could someone tell me what I should do to open my test app from another device in the same network as my local machine?
Since PCFDev was installed in your local machine. I believe you cannot access the cloud foundry apps outside of your machine unless some networking stuff should be done that provide access to other machines.
I've found a solution: using the reverse proxy to redirect request from my local port app's url:
(using nginx as example):
server {
listen 8090;
server_name pcf-rp;
location / {
proxy_pass http://test-ui.local.pcfdev.io;
}
}

So, I have recently started using CF and am using the same to publish a nodejs app to my cf space.
As suggested in the CF wiki, I have used the nodejs_buildpack to
build my app so that can be run via CF PaaS.
Although I don't need this if I push my own cached
node_modules dependency folder in the CF Space , please correct me if I am wrong ?
Following screenshots represent the output of cf push ,
Output of : CF logs STARS --recent
manifest.yml
---
applications:
- name: STARS
buildpack: nodejs_buildpack
memory: 256m
disk_quota: 512MB
instances: 1
command: npm run build
I don't understand why 8080 fails as this works like charm on my machine. i.e. localhost:8080
I do set the express in the following way though,
app.set('port', process.env.PORT || 8080);
// set up listening
app.listen(port, function (err) {
if (err) {
console.log(err)
} else {
opn('http://localhost:' + app.get('port'))
}
})
--Update--
As suggested by #K.AJ in the answer below I have tried to increase the memory limit in my manifest from 256 to 512 and you know what it started working. :)
But its a little strange that the allocation 179.4M in memory and 206.1M on disk is present. Looks like the addition of these two is considered in the deployment process.
My updated configuration is ,
app.set('port', process.env.PORT || 8080);
In the above statement, the port is 8080, only when running locally.
On cloud platforms like PCF, you have no control on which port an app will be running.
If you look closely to the error message, your app is crashing due to out of memory error. The 256MB memory is not enough for it. Try setting it to 1GB first, get it working and then optimize it.
Assuming, you have successfully deployed your app, run cf apps. It should list you the deployed apps along with the route.
Copy the route url for your app and run it in browser. You should be able to see your app, provided your app instance is healthy and in running state.

so... my web site can't access when my computer was power off, none SSL connection...
I want everyone can access my web service 24/7
please give me a method thank you :)
When you want to run a command that continues after your current shell terminates, you should use the nohup command to launch it.
That causes the process to be detached from its initial parent shell so it is not killed when the parent terminates.
I'm trying to install the enterprise edition of neo4j on an existing EC2 (Amazon linux) instance. So far I've
wget "link to enterprise"
untar the file
renamed and moved the folder to NEO4J_HOME
then went into the config files for neo4j.properties to make the following changes:
# Enable shell server so that remote clients can connect via Neo4j shell.
remote_shell_enabled=true
# The network interface IP the shell will listen on (use 0.0.0 for all interfaces)
remote_shell_host=127.0.0.1
# The port the shell will listen on, default is 1337
remote_shell_port=1337
EDITED Christophe Willemsen pointed out that for my original error, I had forgotten to restart the server at that point but I was still unable to access the web server while it was running. So to make it more clear, I've edited the remaining post:
I went to neo4j-server.properties and uncommented:
org.neo4j.server.webserver.address=0.0.0.0
And start the server
NEO4J_HOME/bin/neo4j start
WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.

checking the status:

I can run the shell but the when I go to localhost 7474 I still can not connect
Any help would be appreciative. The only tutorial or help I've found assumed I was starting from scratch with a new instance. If someone could provide some instructions for installing or fix my configuration that would be great.
Thanks!
You have to edit neo4j-server.properties and uncomment the line with:
org.neo4j.server.webserver.address=0.0.0.0
So that the db listens on an external interface not just localhost, and you have to open the port (7474) in your firewall rules.
Make sure to secure access to the db though:
http://neo4j.com/docs/stable/security-server.html
I would like to do some real world data testing on micro cloud foundry but the capacity of postgres database is limited to 256MB which is not sufficient for my testing. Is there a way to increase the db capacity temporarily in offline mode for testing?
If not, can somebody point me the latest instructions of setting up private cloud foundry server on Ubuntu Server 12.04
you can ssh in to the instance, change the configuration for mysql and restart the service.
SSH to the MCF instance :
$ ssh vcap#api.<your-mcf-instance-name-here>.cloudfoundry.me
*note - if you can't remember the password for the vcap user, you can change this via the vm console menu by selecting option 3.
Edit the mysql-node configuration file :
$ vi /var/vcap/jobs/mysql_node/config/mysql_node.yml
the file should look something or exactly like this :
---
local_db: sqlite3:/var/vcap/store/mysql_node.db
base_dir: /var/vcap/store/mysql
mbus: nats://nats:f5dc63f74be5e38f#127.0.0.1:4222
index: 0
logging:

file: /var/vcap/sys/log/mysql_node/mysql_node.log

node_id: mysql_node_1
max_db_size: 256
max_long_query: 3
mysql:

max_long_tx: 0
max_user_conns: 20
mysqldump_bin: /var/vcap/packages/mysql/bin/mysqldump
mysql_bin: /var/vcap/packages/mysql/bin/mysql
gzip_bin: /bin/gzip
ip_route: 127.0.0.1
z_interval: 30
max_nats_payload: 1048576
The two lines you are interested in are;
available_storage: 2048
and
max_db_size: 256
The first line is the maximum available amount of disk storage made available to MySQL, the second is the maximum size per mysql db instance. Set these to your desired values, obviously available_storage has to be large than max_db_size and also a multiple of that value.
Save the file and then restart the VM (shut it down via the menu in the VM console or do it via SSH) and you should be good to go!
WHAT AM I TRYING TO DO
Trying to setup a VCAP on a UBUNTU SERVER VM on my machine by following the steps mentioned at https://github.com/cloudfoundry/vcap/
WHAT IS THE ISSUE
Things seemed to be working fine but at step5 (https://github.com/cloudfoundry/vcap/#step-5-validate-that-you-can-connect-and-tests-pass) I got an exception while trying to execute the following command - vmc target api.vcap.me
The exception that I see on my console is:
Host is not available or is not valid: 'http://api.vcap.me'
Would you like see the response? [yN]: y
HTTP exception: Errno::ECONNREFUSED:No connection could be made because the target machine actively refused it. - connect(2)
ANY OTHER RELEVANT INFO
For some earlier experiments I was using MicroCloud (provided as a download by CloudFoundry). I am having issues in pointing my VMC to this Microcloud as well.
On the Micro Cloud console I see the following message:
To access your Micro Cloud Foundry instance, use:
vmc target http://api.agoel.cloudfoundry.me
When I run this vmc command from the Ruby Command Prompt setup on my Windows7 I get following error:
Host is not available or is not valid: 'http://api.agoel.cloudfoundry.me'
Would you like see the response? [yN]: y
HTTP exception: Errno::ETIMEDOUT:A connection attempt failed because the connected party did not properly respond after a period of time, or
ost has failed to respond. - connect(2)
WHATS DOES VMC INFO DISPLAY
I ran vmc info command on command prompt. It displayed following info
VMware's Cloud Application Platform

MY SETUP DETAILS
Windows7 running on 4GB RAM
Microcloud from Cloudfoundry already installed (this was done as part of some other exercise. My recent experiment requires me to setup a Ubuntu server with VCAP on it. So this MicroCloud should not really matter)
vmc 0.3.18 (installed on my Windows7 machine)
ruby 1.9.2p290 (2011-07-09) [i386-mingw32]
add in your hosts files the following entry:
IP_of_ubuntu_server vcap.me api.vcap.me
If you want to avoid having to edit your hosts file every time you deploy a new app and depending on what virtualisation platform you are using you may be able to forward all traffic on port 80 for your own computer on to the VM.
*.vcap.me is set to resolve to 127.0.0.1 so this is an ideal solution. To do this you should set the network settings to NAT rather than Bridged (maybe you have done this already) and then set port 80 to forward to the IP of the guest OS. In VMWare Fusion for example this is as simple as editing a settings file.
