创建用户

bioinfo, gid, 密码等需要根据注意

外部

#!/bin/bash

user=$1
gid=1000  # bioinfo
shared_home=/data/home/${user}

# get 10 开头的最大 uid
max_uid=$(awk -F: '{print $3}' /etc/passwd | grep 10 | sort -n | tail -1)

# 将最大的 UID 加 1
uid=$((max_uid + 1))

pdsh -w master,node[1-4] "/opt/create_user_in.sh ${user} ${uid} ${gid} no"

# 设置无缝 ssh
username=$user
# Create SSH key pair for the new user, and input an empty passphrase
sudo -u $username ssh-keygen -t rsa -N "" -f $shared_home/.ssh/id_rsa

# Copy the public key to the new user's authorized_keys file to enable passwordless login
cat $shared_home/.ssh/id_rsa.pub >> $shared_home/.ssh/authorized_keys
chown $username:bioinfo $shared_home/.ssh/authorized_keys && chmod 600 $shared_home/.ssh/authorized_keys

echo "User $username created successfully."
