Use five virtual machines to simulate a relatively simple production environment. Direct (poor painting, please forgive me) I. Prerequisites: 1. Have a deep understanding of how DNS works. 2. Compile and install the software package 3. apache service workflow 4. Distinction between static and dynamic websites 5. Basic Database knowledge 6. Network Sharing 7. lvm If you have the above knowledge, it will be clear at a glance (I just painted too bad) Ii. Briefly describe the functions that can be

Vsphere supports storage multipath selection for NFS and iSCSI, which are explained in detail in the following two ways.first, the multipath approach to NFS is described, and NFS is a multi-path IP-based network, although he can do link aggregation through LACP, but he is only a shunt technology, not the bandwidth over

I. Overview 1. Architecture Diagram 2. Software Overview Heartbeat (Linux-HA) Working principle: heartbeat consists of two core parts: Heartbeat monitoring and resource management. heartbeat monitoring can be performed through network links and serial ports, and supports redundant links, they send messages to each other to inform the other party of their current status. If the message is not sent to the other party within the specified time, the other party is deemed invalid, in this case, you

Hat recommends that all critical data be backed up and verified before making any changes to the underlying storage as an unforeseen problem might occur. 1. Create a physical volume from a free disk or partition (e.g./dev/sdc1As a partition) #pvcreate/dev/sdc1 2. Extend the volume group (/dev/sdc1Is an existing physical volume path ). #vgextendvgdata/dev/sdc1 3. Extend the logical volume (/dev/vgdata/lvdataIs the existing logical volume path), which

VMware connects to shared storage in three different ways, San,ip sans (that is, iSCSI) and Nas (NFS). This article is not about the difference between the 3 and the SAN and NAS, please go to Google. Second, this article does not look at FC Sans, if your environment already has a SAN that supports MPIO and has enough storage space, try to make the most of it. Be

NFS storage for ESX typically configures backup links. Automatically switch to the backup link when the primary link fails, which is called failover. Q: When will the failover be launched? A: When a storage link fails to be found. Q: How can I tell if a storage link is interrupted? A: I can't find my heartbeat. Q: W
