（1)Windows上
直接安装nxclient-3.5.0-9.exe即可
（2）Linux上
准备linux rpms
nxclient-3.5.0-7.x86_64.rpm
nxnode-3.5.0-9.x86_64.rpm
nxserver-3.5.0-11.x86_64.rpm
1）首先修改/etc/login.defs文件
$ sudo vim /etc/login.defs
在里面加上两行
SYS_GID_MIN 2000
SYS_GID_MAX 9000
2）
sudo rpm -ivh nxclient-3.5.0-7.x86_64.rpm
3)
sudo rpm -ivh nxnode-3.5.0-9.x86_64.rpm
4)
sudo rpm -ivh nxserver-3.5.0-11.x86_64.rpm
安装好了后，就可以从你的Windows上通过NX连接Linux啦~
This will install and automatically start the server.
If at some later point you need to stop/start/restart the server, use:
sudo /etc/init.d/nxserver {stop|start|restart}
安装 NoMachine(NX) client and server
