Auto-increment type

[Root @ node002 conf] # vi/usr/local/mycat/conf/server. xml

Meaning of each parameter:

0: Local File Auto-increment mode.

1: use mysql auto-increment.

2: Use the local timestamp to auto-increment. (Linux time)

3: zk distributed mode

Because it is not useful before 4, use the fourth (4: zookeeper auto-increment mode). The configuration steps are as follows:

1. Specify the auto-increment type (server. xml)

[Root @ node002 conf] # vi/usr/local/mycat/conf/server. xml

2. Specify the zookeeper address (myid. properties)

[Root @ node002 conf] # vi/usr/local/mycat/conf/myid. properties

3. Specify the primary key of the logical table and enable auto-increment (schema. xml)

[Root @ node002 conf] # vi/usr/local/mycat/conf/schema. xml

4. Specify the table id (MINID, MAXID, and CURID)

 

[Root @ node002 conf] #Vi/usr/local/mycat/conf/sequence_conf.properties

[Root @ node002] #Cd/usr/local/mycat/

[Root @ node002 bin] #./Mycat restart

  • 4. get the file content: get/zk to check whether znode contains the string we created
  • 5. Modify the file content: set/zk "zkbak" to set the string associated with zk
  • 6. delete the file: delete/zk delete the created znode
  • 7. Exit the client: quit
  • 8. help Command: help
