CentOS Use Clush

1, Clush principle is the use of SSH, you can directly put the root password to turn off, in/etc/sudoers plus nopasswd:

All= (All) Nopasswd:all

sudo chmod u+w/etc/sudoers

sudo vi/etc/sudoers

sudo chmod u-w/etc/sudoers

2, Installation Clush

sudo yum install clustershell-y

3, Configuration Clush

Vi/etc/clustershell/groups

ALL:A1 host1 Host2

Name:host3 Host4

It is important to note that all must be configured, Clush has the-a parameter, separated by a space between the hosts.

Clush-a all equals clush-g all

Clush-g Specifying groups

Clush-w Operation host Name

Clush-g Copy--dest file distribution

5, Clush is not supporting the environment variable $path
