linux(ubuntu) 建立一個名為hadoop的使用者和使用者組

寫在前面:無論怎麼确認,還是淚奔了,同一個賬号以前的東西消失了,雖然不多,如同丢失了心愛的東西。

步驟:

1. 建立名為hadoop使用者組

sudo addgroup hadoop

2. 建立名為hadoop的使用者

sudo adduser --ingroup hadoop hadoop

直接一路回車

3. sudo gedit /etc/sudoers

為了讓hadoop使用sudo指令,修改該檔案,在root ALL=(ALL:ALL) ALL下面添加一行:

hadoop ALL=(ALL:ALL) ALL

原檔案備份:

#

# This file MUST be edited with the 'visudo' command as root.

#

# Please consider adding local content in /etc/sudoers.d/ instead of

# directly modifying this file.

#

# See the man page for details on how to write a sudoers file.

#

Defaults    env_reset

Defaults    mail_badpass

Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification

root    ALL=(ALL:ALL) ALL

(應在此處添加修改)

# Members of the admin group may gain root privileges

%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command

%sudo    ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d
