问题 I use ADB over WiFi to connect to an Android device.

The easiest way is to use the setprop command via a root shell on the device. setprop net.hostname TypeAnyHostName If this is not working for you, see other solutions here. This is a temporal solution, the problem repeats again some

Dynamic apache log directory based on hostname

由 萝らか妹 提交于 2019-12-06 16:46:53
I have a PHP application which is used by multiple domains. To avoid maintaining multiple vhosts, I have just setup a single "default" Apache vhost to direct any incoming request to the server to the application directory. What I want to do is to set the Apache access and error log paths dynamically based on the hostname hitting the server. For example, I would like to set the log paths to be something like: /var/log/application_name/example.com/error.log /var/log/application_name/example.com/access.log when a request to example.com is made. Is there a viable way to do this? I've looked at

I want to setup serve multiple sites from one server: 1. http://www.example.org => node.js-www (running on port (50000) 2. http://files.example.org => node.js-files (running on port 50001) Until now I only found out to have docker doing port redirect when using static ips. Is is actual possible to use docker for port redirection via hostname? I use a free amazon EC2 insance. Thanks Bo EDIT : I want to have multiple nodes applications running on the same port but however serving a different hostname. As far as I'm aware docker does not have such functionality built in, nor it should. To

Centos7(RHEL)修改主机名(hostname)

由 一笑奈何 提交于 2019-12-06 10:04:25
在CentOS或RHEL中，有三种定义的主机名: 静态的（static）， 瞬态的（transient）， 灵活的（pretty）。 “静态”主机名也称为内核主机名，是系统在启动时从/etc/hostname自动初始化的主机名。“瞬态”主机名是在系统运行时临时分配的主机名，例如，通过DHCP或mDNS服务器分配。静态主机名和瞬态主机名都遵从作为互联网域名同样的字符限制规则。而另一方面，“灵活”主机名则允许使用自由形式（包括特殊/空白字符）的主机名，以展示给终端用户（如mss01）。 centos7和之前的修改hostname的方式不同，之前修改/etc/sysconfig/network里面的配置文件即可，centos7可以 在CentOS/RHEL 7中，可以用hostnamectl命令查看或修改与主机名相关的配置。 可以使用hostnamectl set-hostname命令来修改hostname 修改pretty级别的hostname可以使用hostnamectl --pretty set-hostname [主机名]来修改 要永久修改主机名，你可以修改静态主机名： hostnamectl --static set-hostname [主机名] 来源： oschina 链接： https://my.oschina.net/u/698000/blog/741988

1、 什么是Linux主机名 无论在局域网还是INTERNET上，每台主机都有一个IP地址，是为了区分此台主机和彼台主机，也就是说IP地址就是主机的门牌号。但IP地址不 方便记忆，所以又有了域名。域名只是在公网（INtERNET)中存在(以实验为目的的局域网域网实验性除外），每个域名都对应一个IP地址，但一个IP 地址可有对应多个域名。域名类型 Linux sir.org 这样的； 主机名是用于什么的呢？在一个局域网中，每台机器都有一个主机名，用于主机与主机之间的便于区分，就可以为每台机器设置主机名，以便于以容易记忆的方法来相互访问。比如我们在局域网中可以为根据每台机器的功用来为其命名。主机名相关的配置文件：/etc/hosts; 2. Linux主机名配置文件 主机名的配置文件大多是/etc/hosts ；hosts - The static table lookup for Linux hostname（主机名查询静态表）；由于 Linux发行版本众多，与主机名相关的配置文件有时也有所不同。现在我们说说常见版本的主机名配置文件； 2.1 Linux主机名置文件 /etc/hosts Fedora/Redhat 或以Fedora/Redhat为基础打包的发行版，主机名配置文件是 /etc/hosts Debian或以Debian为基础打包的发行版，主机名配置文件是 /etc
