并发批量管理500台以上服务器脚本分享（shell版）

2014-06-01脚本930阅读模式

也许很多人认为shell不能并发任务，其实可通过其它一些方式来实现。下面的脚本是我批量快速管理500+服务器脚本，阅读该脚本前建议先看《自动执行远程主机命令expect脚本》、《自动远程拷贝expect脚本》和《getopt：命令行选项、参数处理》

用法：

Usage: ./multi_main.sh [-h|--help]
                 [-v|-V|--version]
                 [-l|--iplist ... ]
                 [-c|--config ... ]
                 [-t|--sshtimeout ... ]
                 [-T|--fttimeout ... ]
                 [-L|--bwlimit ... ]
                 [-n|--ignore]

cat config.txt #上传文件和执行命令

file:::~/scripts/test.sh /root/ push
com:::./test.sh

cat iplist.txt #ip列表

# Usage:
#ip port user password [password_2] [password_3] [password_4]
# Example:
#192.168.0.100 22 root 123456
192.168.0.200 22 root 123456
192.168.0.201 22 root 123456
...

./multi_main.sh -c config.txt -l iplist.txt #开始执行，可查看result目录下的日志来分析是否执行成功

脚本如下：

mssh.exp 执行远程服务器命令expect脚本
mscp.exp 向远程服务器上传或下载文件expect脚本（rsync）
thread.sh 向一台服务器发起动作
ckssh.py 检查ssh是否通
multi_main.sh 批量执行，对每台调用thread.sh

mssh.exp:

    @ yeho 不存在报错，是我搞错了，是否可以在远程主机上执行本地脚本？

请问版主，你用这个脚本管理500台机器同时执行某个任务，一般需要多长时间

  @ 唯影具体要看并发数和单台服务器执行命令时间。

    @ yeho 额，像这样，假如500台机器上面都分别有一个10G的数据库，我要同时发出执行备份的命令，请问怎样控制并发数？我看了以上的脚本没找到控制并发数量的参数，希望指点指点

执行这个脚本时都需要什么环境，expect和Python的环境都要配置吗

  @ Q丶安装expect即可
