vsphere replication

What are the files that make up the virtual machines in the VMware vsphere virtualization platform? What is the meaning of composing a file separately? What are the areas of attention when excluded? There is a virtualization expert Eric Siebert's article, introduced the virtual machine file composition, write very detailed, although ESXi has upgraded several versions, but still use, here reference the following figure, at the same time I take vcenter

I believe we all know how to configure the HA function in the vsphere environment, know ha failover time for VM system startup time + Application start time + 15 seconds of heartbeat detection time, know ha is not affected by DRS and Vmotion, Know ha do not need to rely on vcenter (vcenter Hung, license authorized ESXi host only 3 days after the virtual shutdown can not be opened), know Ha is through the ESXi host network heartbeat detection failure,

Recently for some reason a Linux virtual machine, and then boot found unable to ssh. But can ping through the gateway, outside but can not ping it, troubleshooting for a long time, add a new virtual network card is not, found that their subnets are through, but not out. Guessing is a routing problem, execution route-n found that the default route did not.Check Configuration Vi/etc/sysconfig/network-scripts/ifcfg-eth0the arrow position defroute=no; Change to Yes to restart the network service jus

The ultimate goal of data replication is to synchronize the data of one server with the data of another server, which can achieve data redundancy or load balancing of services. A master server can connect multiple slave servers, and the slave server can act as the master server in turn. The master-slave server can be located in different network topologies. Due to the powerful mysql replication function, th

The previous blog said how to use Xtrabackup to back up and restore databases. After the database has been restored, the two machine databases are the same, including Binlog file and Pos.At the same time, after the Xtrabackup backup is completed, the relevant Binlog file and POS information has been written to the backup information file, and the cat can view it under Linux. Then execute the Change Master command on the standby to successfully build the master-slave

VMware vsphere provides virtual machines with a virtualized infrastructure that divides physical resources into resources and provides virtual resources, including CPU and memory, for each virtual machine. To allocate these resources well, you must use a resource pool. Resource pools are logical abstractions that manage resources flexibly. Resource pools can be grouped into hierarchies that are used to partition the available CPU and memory resources

allocates resources in two ways: by migrating the virtual machine to another server with more appropriate capital, or by migrating other virtual machines on that server, freeing up more "space" for that virtual machine.In fact, VMware DRS is primarily an ESXi server in a load-balanced cluster. VMware DRS will continuously monitor all hosts in the cluster, monitoring the distribution and usage of the CPU, memory resources of the virtual machine. DRS compares this write metric to the resource uti

How does vSphere Web Client 6.5 upload iso files?1, first turn on the SSH function.Web login management side, select a host, configuration-security profile-service edit-ssh-start.2. Upload the ISO file with SFTP.Connect the host with SFTP, go to the Sftp://[email protected] host ip/vmfs/volumes/vsandatastore/iso/directory, upload the ISO file.3. Turn off the SSH feature.Refer to the first step to stop SSH. If you do not close, there will be repeated s

In the process of erecting a virtual server using Vmwaer vsphere, the problem of Vmwaer vsphere client being unable to connect to Vcenter server was encountered. First, the failure description: Second, find and solve the problem of the method: 1, verify the login vcenter server, IP address, username, password is correct. If correct, proceed to the next step. 2, verify that the Vcenter Server service is sta

Before we briefly introduced the VMware vsphere 5.0, Next, we started to download the installation ESXi 5, download the address for Https://my.vmware.com/web/vmware/info/slug/datacenter_cloud_ Infrastructure/vmware_vsphere/5_0, you may need to register to download normally. ESXi 5 can be tested for 60 days free of charge. ESXi 5 can be installed directly on the server, where we use the test environment to install, I use the VM workstation 8.0来 install

This Monday evening the new company part of the staff dinner, round table nine people sit around, the eight, all five years of it age, eldest brother for the elderly. Play a game during the dinner and find the common ground, One person Yue, there are white-haired people drink, the public will all toast, all.

Core componentsVsphere is a system that can be installed and run on naked machines independently, so unlike other VMware Workstation software we have seen before, it is no longer dependent on the host operating system. After ESXi is installed, we can create multiple VMS (virtual machines) on the ESXi server with vsphere Client remote connection control, and install the Linux/windows Server system for these virtual machines to become virtual servers th

MariaDB's GTID replication and multi-source replication, mariadbgtid Replication What is GTID? GTID is the global transaction ID (global transaction identifier). It was initially implemented by google and officially added to MySQL in MySQL 5.6. GTID is actually composed of UUID + TID. UUID is the unique identifier of a MySQL instance. TID indicates the number of

Asynchronous replication: MySQL natively supports one-way, asynchronous replication. Asynchronous replication means there is a delay in copying data from one machine to another-most importantly this means that the data cannot be copied/applied to the slave at the same time when the application's transaction commit has been confirmed. Typically, this delay is dete
