Learn a little about mysql dual-host hot backup-quickly understand the principle and practice of mysql master/slave backup Thank you for learning Git in the previous article-quick start with git in 20 minutes. Here we will share the dry goods and briefly introduce the simple practices of mysql dual-host and multi-host remote hot standby. The concept of dual-machine hot standby is simply to maintain automatic synchronization of the two databases. Opera

The data synchronization function of mysql not only provides load balancing for database queries to a certain extent, but also provides great help for database redundancy, backup, recovery, and load balancing. The data synchronization function can be implemented through master-slave replication, while master-slave replication is performed asynchronously. mysql only supports one

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 t

MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary server, one or more servers as from the server. No data is written from the server, and the source of the data is the primary server. The purpose of the replication is to synchroniz
