Sunseekers/Vue: vue实例练习与总结. Keeping multiple web servers in sync with rsync – Stephen R Lang. People looking to create a load balanced web server solution often ask, how can they keep their web servers in sync with each other?
There are many ways to go about this: NFS, lsync, rsync, etc. This guide will discuss a technique using rsync that runs from a cron job every 10 minutes. There will be two different options presented, pulling the updates from the master web server, and pushing the updates from the master web server down to the slave web servers.

多数的朋友都是这样：再加一颗新硬盘，然后重新分割、格式化，将 /home 的数据完整的复制过来， 然后将原本的 partition 卸载重新挂载新的 partition 。 啊！ 好忙碌啊！ 若是第二次分割却给的容量太多！ 导致很多磁碟容量被浪费了！ 调整 Linux 分区，第 2 部: 高级分区调整. 调整 Linux 分区，第 2 部 LVM、故障排除和供选方案.

[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target. Systemd 入门教程：命令篇. Systemd 是 Linux 系统工具，用来启动守护进程，已成为大多数发行版的标准配置。 本文介绍它的基本用法，分为上下两篇。 今天介绍它的主要命令，下一篇介绍如何用于实战。 一、由来. Systemd 入门教程：命令篇. 编写systemd下服务脚本. Red Hat Enterprise Linux 7（RHEL 7）已经将服务管理工具从SysVinit和Upstart迁移到了systemd上，相应的服务脚本也需要改变。 前面的版本里，所有的启动脚本都是放在/etc/rc.d/init.d/ 目录下。 这些脚本都是bash脚本，可以让系统管理员控制这些服务的状态，通常，这些脚本中包含了start，stop，restart这些方法，以提供系统自动调用这些方法。
但是在RHEL 7中当中已经完全摒弃了这种方法，而采用了一种叫unit的配置文件来管理服务。 ■Systemd下的unit文件 Unit文件专门用于systemd下控制资源，这些资源包括服务(service)、套接字(socket)、设备(device)、挂载点(mount point)、自动挂载点(automount point)、交换文件或分区(a swap file or partition)… 所有的unit文件都应该配置[Unit]或者[Install]段.由于通用的信息在[Unit]和[Install]中描述，每一个unit应该有一个指定类型段，例如[Service]来对应后台服务类型unit. unit 类型如下：service ：守护进程的启动、停止、重启和重载是此类 unit 中最为明显的几个类型。 Mount ：此类 unit 封装系统结构层次中的一个挂载点。 ■认识service的unit文件 扩展名：.service. 总结 - Linux初始化过程（init系统）
一般情况下，我们是不需要知道Linux启动时候的初始化过程的，这其实是一件挺烦躁的事情。 Sendmail配置经验总结. 从昨天晚上忙到今天晚上，一直在研究sendmail和DNS相关知识，还翻阅了O'Reilly的sendmail, 3rd edition和DNS and BIND，对sendmail这个小东西还真费了些神，现在总算搞得差不多了。 Lubuntu - installing VNC server - Home Circuits. I use vnc to access graphic interface from my PC to cubieboard that runs on lubuntu. I have chosen tightvncserver and spent some time to configure and run it. Also to my surprise it took me a while to set it up correctly. VirtualBox 5.1 Released - Install on RHEL/CentOS/Fedora and Debian/Ubuntu/Linux Mint. VirtualBox is an open source cross-platform virtualization software, it can be installed on any operating system and enable you to install and run multiple guest operating systems on same computer. For example, if you install it on your Linux system, you can run Windows XP operating system under it as a Guest OS or run Linux OS on your Windows system and so on.
This way, you can install and run as many as guest operating systems as you like, the only limit is disk space and memory. Recently Oracle has released latest stable version of Virtualbox 5.1.0, the newest version of Virtual box comes with so many major changes and new features added to it. Whats new in Virtualbox 5.1 You can see the complete new change log details about VirtualBox 5.1 on their Official Changelog Page. Sulogin 解決.
