Nacos The persistence of

There is no need for the registry to persist data to the database , It can be persisted to the local hard disk . The distributed configuration center will persist the data to the local embedded database by default .

• By default , The data of the distributed configuration center is stored locally data Under the table of contents .
• If you don't cluster , Once down, the entire configuration center cannot be used .
• If we do clustering , The synchronization of data cannot be guaranteed .
• So the data should be stored in a unified and shared database .

stay 0.7 Before the release , In stand-alone mode nacos Use embedded database to store data , It is not convenient to observe the basic situation of data storage .0.7 Support for mysql Data source capabilities , Specific operation steps ：

1. mount this database , Version for ：5.6.5+
2. initialization mysql database , Database initialization file ：nacos-mysql.sql
3. modify conf/application.properties file , Increase support mysql Data source configuration （ Currently only supported mysql）, add to mysql Data sources url、 User name and password .

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=root

Tips：

A、 If there is data in the original memory , After using the database , The data in the database will prevail , The data in memory is not displayed .
B、 The registry will not be put into the database , It is necessary to put the configuration center into the database .
