Install nodejs 0.9.0 in centos 6

Ensure that python is installed. Most installation failures are caused by the low Python version. Before installation, upgrade python to http://www.tomtalk.net/wiki/python.

[Root @ SNDA-192-168-15-161 ~] # Python-V
Python 2.7.3
Start installation:

1) download nodejs to the local device and decompress it.
[Root @ SNDA-192-168-15-161 node] # wget http://nodejs.org/dist/v0.9.0/node-v0.9.0.tar.gz
[Root @ SNDA-192-168-15-161 node] # tar zxvf node-v0.9.0.tar.gz
2). Go to the directory to compile and install
[Root @ SNDA-192-168-15-161 node-v0.9.0] # cd node-v0.9.0
[Root @ SNDA-192-168-15-161 node-v0.9.0] #./configure -- prefix =/usr/local/node/0.9.0
It is installed in the/usr/local/node/0.9.0 directory.
[Root @ SNDA-192-168-15-161] # Make
[Root @ SNDA-192-168-15-161] # make install
3) Configure node_home
[Root @ SNDA-192-168-15-161] # vi/etc/profile
In export path user... Add the following content to the line and set node_home/bin to the system path.
# Set for nodejs
Export node_home =/usr/local/node/0.9.0
Export Path = $ node_home/bin: $ path
Save and exit, and execute the following command to make the configuration take effect.
[Root @ SNDA-192-168-15-161] # source/etc/profile

Run the node-H command to verify that the setting is successful.

[root @ SNDA-192-168-15-161 ~] # Node-H

[Root @ SNDA-192-168-15-161 ~] # Vi app. js

VaR HTTP = require ('http ');
VaR IO = require ('socket. Io ');
VaR Server = http. createserver (function (req, Res ){

Res. writehead (200, {'content-type': 'text/plain '});
Res. End ('Hello World ');
});

Server. Listen (process. argv [2]);

VaR socket = Io. Listen (server );
Socket. On ('connection', function (client ){
Console. Log ('client has connected ');
Client. On ('message', function (){});
});
