http://www.cnblogs.com/melonjiang/p/5342505.html http://www.django-china.cn/topic/1054/ 1、连接方式   redis-py提供两个类Redis和StrictRedis用于实现Redis的命令,StrictRedis用于实现大部分官方的命令,并使用官方的语法和命令,Redis是StrictRedis的子类 #!/usr/bin/env python # -*- coding:utf-8 -*- import redis r = redis.Redis(host='192.168.0.110', port=6379,db=0) r.set('name', 'zhangsan') #添加 print (r.get('name')) #获取 2、连接池    redis- py使用connection pool来管理对一个redis server的所有连接,避免每次建立、释放连接的开销。默认,每个Redis实例都会维护一个自己的连接池。可以直接建立一个连接池,然后作为参数 Redis,这样就可以实现多个Redis实例共享一个连接池。 #!/usr/bin/env python # -*- coding:utf-8 -*- import redis pool = redis.ConnectionPool

1、String 操作   redis中的String在在内存中按照一个name对应一个value来存储 set() #在Redis中设置值,默认不存在则创建,存在则修改 r.set('name', 'zhangsan') '''参数: set(name, value, ex=None, px=None, nx=False, xx=False) ex,过期时间(秒) px,过期时间(毫秒) nx,如果设置为True,则只有name不存在时,当前set操作才执行,同setnx(name, value) xx,如果设置为True,则只有name存在时,当前set操作才执行''' setex(name, value, time) #设置过期时间(秒) psetex(name, time_ms, value) #设置过期时间(豪秒) mset() #批量设置值 r.mset(name1='zhangsan', name2='lisi') #或 r.mset({"name1":'zhangsan', "name2":'lisi'}) get(name) 获取值 mget(keys, *args) #批量获取 print(r.mget("name1","name2")) #或 li=["name1","name2"] print(r.mget(li)) getset(name, value)

linux挂载新硬盘,开机自动挂载

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 说到挂载文件系统了,说一下挂载u盘啊 外部磁盘之类的。 挂载u盘必须先 fdisk -l 看一下/dev 下边有没有识别到u盘, 然后用mkdir命令在/mnt目录下为u盘新建一个文件目录,然后执行mount命令把u盘挂载到/mnt对应的文件夹下,然后就能查看修改u盘里的东西了。 如果不想每次开机都这个挂载的话,必须修改/etc/fstab 文件,设置开机自动挂载。 稍微截个图发俩命令吧: 最下边那个/dev/sdb1就是u盘 这个usb文件夹就是我为挂载u盘建的。然后执行 mount -t vfat /dev/sdb1 /mnt/usb 命令挂载u盘。 挂载成功,如果要实现开机自动挂载的话,修改/etc/fstab文件, 我的是这样修改的,见下图。 最后一行是我自己加的,不知道UUID的用这个命令 ls -l /dev/disk/by-uuid 或者自己百度! http://blog.csdn.net/catoop/article/details/7334901 由于公司文件服务器整个文件容量为850G。为了加强服务器的可用性,将架设一台备用服务器在线随时替换,可以恢复到前一天晚上23.59的状态。 备用服务器系统盘空间不够,另外增加一块1t的硬盘作为保存再用文件服务器同步硬盘。 具体操作过程如下:

Linux - understanding the mount namespace & clone CLONE_NEWNS flag

余生长醉 提交于 2019-12-29 18:43:36
问题 I am reading the mount & clone man page. I want to clarify how CLONE_NEWNS effects the view of file system for the child process. (File hierarchy) Lets consider this tree to be the directory hierarchy. Lets says 5 & 6 are mount points in the parent process. I clarified mount points in another question. So my understanding is : 5 & 6 are mount points means that the mount command was used previously to 'mount' file systems (directory hierarchies) at 5 & 6 (which means there must be directory

Accessing linux mount location on windows through jenkins

问题 I have path /opt/test/share mounted on ubuntu and shared with everyone using samba. I have mapped Z: drive on windows to above path. Now, If I do cd Z:/ and then dir from local windows box, it works fine. But if I try to do same thing through jenkins it says "The system cannot find the path specified" Please help. 回答1: Is Jenkins running on the Windows machine as you or as a Windows Service. Mounting in Windows is user dependent. If you are running Jenkins as a Service on Windows, you will

Where is a file mounted?

℡╲_俬逩灬. 提交于 2019-12-29 03:21:06
问题 Given a path to a file or directory, how can I determine the mount point for that file? For example, if /tmp is mounted as a tmpfs filesystem then given the file name /tmp/foo/bar I want to know that it's stored on a tmpfs rooted at /tmp . This will be in C++ and I'd like to avoid invoking external commands via system() . The code should be robust--not necessarily against deliberate tampering but definitely in the face of nested mountpoints, symlinks, etc. I haven't been able to find a simple

Mount volume to Docker image on OSX

问题 On a Mac, how do you mount a volume to a Docker container? On my linux box, this is easy. All I need to do is something like -v /src/webapp:/opt/webapp when running the container. But Mac is different since I have to run boot2docker to run a VM in VirtualBox. I've tried running boot2docker init boot2docker up boot2docker ssh # to poke around boot2docker stop VBoxManage sharedfolder add "boot2docker-vm" --name "Users" --hostpath /Users boot2docker up boot2docker ssh "sudo modprobe vboxsf" but
