Centos 6.4默认没有安装scp和lrzsz，yum装下
1.安装scp
[root@localhost ~]# scp
-bash: locate: command not found
[root@localhost ~]# yum install openssh-clients
[root@localhost ~]# scp
usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port] [-S program]
[[user@]host1:]file1 ... [[user@]host2:]file2
[root@localhost ~]# scp /root/hostcheck/check.tar.gz root@192.168.200.70:/root/
2.安装lrzsz
[root@localhost ~]# yum install lrzsz
