DevOps(9)Build the NodeJS Env
 
1. Memcached and Monitor
Command to start memcached
>memcached -d -m 50 -p 11211 -u carl -l 0.0.0.0
 
Install the Memcache-Top
Prepare the right directory
> mkdir /home/carl/tool/memcache-top-v0.6
> mkdir /home/carl/tool/memcache-top-v0.6/bin
> mv memcache-top-v0.6 /home/carl/tool/memcache-top-v0.6/bin/memcache-top
> chmod a+x /opt/memcache-top/bin/memcache-top
 
Start the Monitor Tool
> memcache-top --sleep 3 --instance ubuntu-dev1,ubuntu-dev2
 
The output will be as follow:
memcache-top v0.6 (default port: 11211, color: on, refresh: 3 seconds)

INSTANCE USAGE HIT % CONN TIME EVICT/s READ/s WRITE/s
ubuntu-dev1:11211 0.0% 0.0% 5 1.6ms 0.0 2 367
ubuntu-dev2:11211 0.0% 0.0% 5 1.5ms 0.0 2 367

AVERAGE: 0.0% 0.0% 5 1.6ms 0.0 2 367

TOTAL: 0B/ 0.1GB 10 3.1ms 0.0 4 733
(ctrl-c to quit.)
 
2. Prepare the NodeJS Env
follow
 
I was using version python 2.7.6 and node 0.10.28. I will try different this time on my local and VM.
> ./configure --prefix=/home/carl/tool/node-v0.12.0
make it and install that.
> node -v
v0.12.0
 
Install gulp
> sudo npm install -g gulp
 
or
 
> npm install --global gulp
 
> gulp -version
[13:31:35] CLI version 3.8.11
 
Install the NODEJS Plugin in jenkins
Install the GitHub Plugin in Jenkins
Install the  SSH plugin in Jenkins
 
3. Prepare deploy Env
 
> sudo apt-get install git
> npm install pm2 -g
> pm2 -v
[PM2] Spawning PM2 daemon
[PM2] PM2 Successfully daemonized
0.12.7
 
gulp command to get the dist and deploy
>gulp serve
>gulp clean
>gulp dist
>gulp deploy

//run app using nodemon
gulp.task('serve', [], function(){
return nodemon({

watch : paths.sources
});
});

Unzip the binary
>mkdir sillycat-secure-proxy-1.0
>tar zxvf sillycat-secure-proxy-1.0.tar.gz -C ./sillycat-secure-proxy-1.0
 
Deploy the binary
Download the binary from artifactory
>mkdir sillycat-secure-proxy-1.0
>tar zxvf sillycat-secure-proxy-1.0.tar.gz -C ./sillycat-secure-proxy-1.0
>pm2 start app.js --name sillycat-secure-proxy -i max
 
Stop the binary
>pm2 stop sillycat-secure-proxy
 
Restart the binary
>pm2 restart sillycat-secure-proxy
 
Watch all the node applications
>pm2 list
 
Jenkins can finish the deployer work
. ~/.profile
cd /opt/sillycat-secure-proxy
pm2 stop sillycat-secure-proxy
rm -fr *
wget --user=deployer --password=deployer http://ubuntu-pilot:8080/artifactory/libs-release-local/com/sillycat/sillycat-secure-proxy/sillycat-secure-proxy-1.0.tar.gz
tar zxf sillycat-secure-proxy-1.0.tar.gz
pm2 restart sillycat-secure-proxy
 
Or
 
. ~/.profile
cd /opt/sillycat-secure-proxy
pm2 delete sillycat-secure-proxy
rm -fr *
wget --user=deployer --password=deployer http://ubuntu-pilot:8080/artifactory/libs-release-local/com/sillycat/sillycat-secure-proxy/sillycat-secure-proxy-1.0.tar.gz
