Installing Node.js via package manager

Source:
http://www.unixmen.com/install-node-js-centos-7/

epel’s repo 要事先安排好，如果沒有可以參照以下:
wget -r --no-parent -A 'epel-release-*.rpm' http://dl.fedoraproject.org/pub/epel/7/x86_64/e/

rpm -hiv epel-release-7-5.noarch.rpm
會在 /etc/yum.repos.d 底下建立兩個 epel’s repo 檔案  


yum -y install npm

yum -y install nodejs

安裝好 nodejs 之後
編輯一個文字檔，進行測試

vi hello.js

var http = require('http');
http.createServer(function (request, response) {
 response.writeHead(200, {'Content-Type': 'text/plain'});
 response.end('Hello World\n');
 }).listen(8080);

console.log('Server started');
存檔

執行
node hello.js

打開瀏覽器
http://127.0.0.1:8080
看到 Hello World 即可。

node -v 確認版本



另一種安裝方法:

wget http://nodejs.org/dist/v0.10.30/node-v0.10.30-linux-x64.tar.gz

tar xzvf node-v* && cd node-v*

sudo yum install gcc gcc-c++

./configure
make

node --version 確認版本

會在 /etc/yum.repos.d 底下建立兩個 epel’s repo 檔案  

接下來

編輯 xrdp.repo
vi /etc/yum.repos.d/xrdp.repo

[xrdp]
name=xrdp
baseurl=http://li.nux.ro/download/nux/dextop/el7/x86_64/
enabled=1
gpgcheck=0


安裝 Installation:

yum -y install pixman libXfont xrdp tigervnc-server

以下兩個動作 很重要：
chcon --type=bin_t /usr/sbin/xrdp
chcon --type=bin_t /usr/sbin/xrdp-sesman

如果失敗了，先下以下指令
ls -Z /usr/sbin
找到 xrdp 等檔案，發現有 ? 符號
以下列指令修改屬性，例如：
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp-chansrv
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp-sesman
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp-sessvc

然後再檢查一次，
ls -Z /usr/sbin
直到都沒有 ? 符號，成功之後，再回頭下剛剛那兩個指令

接下來，編輯 vi /etc/xrdp/sesman.ini
找到 [Xnvc] 這一段，加入以下：

param7=-depth
param8=24

確定 param 數字號碼是連續的。


要修改 xrdp 對外服務的 PORT 號碼則
vi /etc/xrdp/xrdp.ini
改掉 3389 的值

檔案最尾巴加入以下:
[xrdp8]
name=Reconnect
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=5910



啟動服務：
systemctl stop firewalld
systemctl disable firewalld
systemctl enable xrdp.service
systemctl start xrdp.service



防火牆如果需要打洞3389
firewall-cmd --permanent --zone=public --add-port=3389/tcp
firewall-cmd --reload
