console. 2. The newly purchased instance is originally in an uninitialized state, and needs to be initialized on the console.

4 Purchase & Initialization 1. After purchasing a CDB on Tencent Cloud, users can enter the console, and perform necessary operations (such as name modification and initialization) on the purchased CDB instance on the console. 2. The newly purchased instance is originally in an uninitialized state, and needs to be initialized on the console. During initialization, you need to specify the character set supported for the purchased CDB, determine whether the table name is case-sensitive, and set the root account password for the CDB, as shown in the figure below: You can view the initialization and other operation tasks in the list of tasks on the console. After the CBD is initialized, CBD instance will be running, as shown in the figure below: 第 4 页共 9 页

5 Now, you can log in to CDB, enter the management interface, and perform such operations as capacity and memory upgrade. 第 5 页共 9 页

6 Connection There are two methods to connect to CDB: Public network access: You can log in to phpmyadmin through the login entry on the console with a public network account, and perform operations on the database (the public network address is disabled by default). Refer to CDB for MySQL Database Management for subsequent operations or use a connection tool from a third party; In the other method, with an automatically assigned private network address, you can access the database by using the CVM in the same availability zone. The latency is relatively low because a high-speed private network is employed in this method. 第 6 页共 9 页

7 Manage Database CDB for MySQL management entry enables viewing and modification of database instance details, instance monitoring, parameter configuration, account management, database operations, backup management, as well as download of database operation logs, rollback and upgrade, etc. 1. Instance details. You can view and operate on various information of databases, as shown in the figure below. The public network address is disabled by default, and you need to enable it manually. 2. Instance monitoring. You can monitor multiple key indicators running in the current database from the following six dimensions: access, load, query cache, table, Innodb and MyISAM. The monitoring data items for access include statistics for sql operations such as numbers of slow queries, full table scans, queries, updates, deletions, insertions, and overwrites, total number of requests, number of current connections and connection usage and other server service indicators. With these data, you can get an overall sense of operations currently performed on the database in real time. The monitoring data items for load include real disk capacity, total disk capacity, volume rate, and sent and received data volume. These data can reflect some indicators such as database space increase, and can be used as the basis for database upgrade. The monitoring data items for query cache include cache hit rate and cache usage. This indicator reflects the cache efficiency of database. When there is a low cache hit rate, you need to analyze the SQL operations on the service. The table monitoring contains two indicators: number of temporary tables and number of table lock waits. If there are too many temporary tables, there might be a large number of 第 7 页共 9 页

8 data table connection operations. In this case, the query efficiency will be severely affected, and you need to optimize the query then. InnoDB monitoring and MyISAM monitoring are used to monitor the running indicators of these two storage engines respectively, so that the administrators can better understand the running status of the actual table (the above two storage engines may be used). 3. Parameter configuration. You can configure the modifiable parameters in the database and view the modification history, as shown in the figure below: 4. Account management. You can modify the password of the default root account in the system, as shown in the figure below: 第 8 页共 9 页
