scp自动备份
scp自动备份
2021-06-02
一台FTP服务器, 查看文件是否占用过多空间. 然后就scp到指定服务器. 删除过期文件
已提前使用
ssh-keygen -t rsa ssh-copy-id -i root@server
添加相关信任
本来想用 pexpect 模块自动输入密码. 然后发现这个在复制大文件似乎有问题. 查了一下说更改下面的文件
vi /usr/lib/python2.7/dist-packages/pxssh.py # 说在这个地方再添加 self.sendline() time.sleep() 试了不行. 135 self.read_nonblocking(size=10000,timeout=1) # GAS: Clear out the cache before getting the prompt 136 time.sleep(0.1) 137 self.sendline()
