rc.local

1. 新建文件
# /etc/systemd/system/rc-local.service
=================================
[Unit]
 Description=/etc/rc.local Compatibility
 ConditionPathExists=/etc/rc.local

[Service]
 Type=forking
 ExecStart=/etc/rc.local start
 TimeoutSec=0
 StandardOutput=tty
 RemainAfterExit=yes
 SysVStartPriority=99

[Install]
 WantedBy=multi-user.target
===============================
 
2. 激活服务
$ sudo systemctl enable rc-local.service

3. 新建rc.local，并给执行权限
$ sudo chmod +x /etc/rc.local
*如果原来存在的/etc/rc.local 检查是否有执行权限,但是不生效，检查是否有执行权限，注意权限给/etc/rc.d/rc.local，/etc/rc.local只是其软链接*

python描述符

http://fanchunke.me/Python/Python%E4%B8%AD%E7%9A%84%E5%B1%9E%E6%80%A7%E8%AE%BF%E9%97%AE%E4%B8%8E%E6%8F%8F%E8%BF%B0%E7%AC%A6/ 只定义__get__则为非数据描述符，同时定义__get__和__set__才是数据描述符。

优先级 data descriptor > instance dictionary > non-data descriptor > __getattr__

  • descriptors are invoked by the getattribute() method
  • overriding getattribute() prevents automatic descriptor calls
  • getattribute() is only available with new style classes and objects
  • object.getattribute() and type.getattribute() make different calls to get().
  • data descriptors always override instance dictionaries.
  • non-data descriptors may be overridden by instance dictionaries.

property(fget=None, fset=None, fdel=None, doc=None) -> property attribute

大文件传输

server B: nc -l 0.0.0.0 PORT | tar -zxvf -

加上pv可以显示速度
