利用expect去自动执行安装docker的脚本

set host [lindex $argv 0]
# set username [lindex $argv 1]
set password [lindex $argv 2]

# spawn ssh root@$host "nohup sh -c "$(curl -fsSL https://hjr-tmp.obs.cn-north-4.myhuaweicloud.com/rsipac_docker.sh)" > run.log"
spawn ssh root@$host "wget https://hjr-tmp.obs.cn-north-4.myhuaweicloud.com/rsipac_docker.sh && nohup bash rsipac_docker.sh > run.log"
expect "*Are you sure you want to continue connecting (yes/no)?*" {send "yesr"}
expect "*password*" {send "$passwordr"}

interact

spawn scp root@$host:/root/run.log "$host.log"
expect "*password*" {send "$passwordr"}
interact

利用python的多线程去安装

import os
f = open('ip60.txt')
lines = f.readlines()
f.close()
#  for line in lines[2:4]:
#      url = line.strip()
#      print('############################## {} #############################'.format(url))
#      print('############################## url #############################')
#      print('############################## url #############################')
#      print('############################## url #############################')
#      os.system("./rsipac.sh {}".format(url))

def multiprocess_run(process, obj_list):
    # python -c "import multiprocessing; print(multiprocessing.cpu_count())"
    import sys
    from tqdm import tqdm
    from multiprocessing import Pool
    import multiprocessing
    import time
    cpus = multiprocessing.cpu_count()
    pool = Pool(processes=30)
    result_list = []
    tic = time.time()
    for result in tqdm(pool.imap(process, obj_list)):
        result_list.append(result)
        sys.stdout.flush()
    toc = time.time()
    print('time waste', toc - tic)
    return result_list

    url = line.strip()
    print('############################## {} #############################'.format(line))

    #  print('############################## url #############################')
    #  os.system("./rsipac.sh {}".format(url))
