NOTES

  1. If due to any reason like slow ISP, network issues, if create lab vagrant up --provision got failed, then just re-run the vagrant up --provision command to create lab.
  2. Once you done with usage of PORP LAB, you can just simply run vagrant halt command to power off the nodes and Next time when you need again PORP LAB then just run vagrant up --provision to start all lab nodes.
  3. Error :-
Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to create the host-only adapter
VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface

SLEEP thread causing "Waiting for table metadata lock"

SLEEP thread causing "Waiting for table metadata lock" We might have faced some scenarios once our db connection threads are getting locked and we try to find the culprit thread id which is locking the thread, to kill and release the connections.  Here I am going to focus on one of the scenarios when db connection threads are locked at state " waiting for table metadata lock " and when we see the processlist, we can't find any thread which is running and using the same table, i.e., all threads are in SLEEP state except the locked threads. Such as :  mysql [localhost:5726] {msandbox} (world) > show processlist\G *************************** 1. row ***************************            Id: 5          User: rsandbox          Host: localhost:60624            db: NULL       Command: Binlog Dump       ...

errno: 24 - Too many open files You might see this error inside MySQL's error log file or during mysql_upgrade operation. Can't open file: ‘./db/table.frm' (errno: 24 - Too many open files) To solve this issue, you will need to change the open files limit at system and db service level. --> To check and change this limit at the system level, we use ulimit client tool to set it dynamically. * Check current system open file limit. root@test:~# ulimit -a core file size          (blocks, -c) 0 data seg size           (kbytes, -d) unlimited scheduling priority             (-e) 0 file size               (blocks, -f) unlimited pending signals            ...

How to properly shutdown MySQL before any maintenance activity

How to properly shutdown MySQL before any maintenance activity We might have different scenarios once we need to stop MySQL service before performing either server or database activity like patching/upgrade.   Before performing such activity, we need to make sure that we stop MySQL service properly to avoid any unforeseen crashes once our maintenance activity complete and MySQL service is started.  Here I would like to share the below steps which should be performed and take care to properly stop MySQL service.  Step 1: Ensure we don't have any long-running queries. Manually verify by checking the processlist. show processlist;  Step 2: If it is the master node, then ensure to stop application write hits on the database by doing either stop an app and put in maintenance OR if we have any failover solution then move write hits on another node.  Step 3: If it is a slave node, then STOP replication and note down t...

set --server-id to enable either a master or a slave

By
set --server-id to enable either a master or a slave Below issue can be faced, when we run CHANGE MASTER command to setup replication. mysql> change master to master_host='xx.xx.xx.xx',master_user='rep_user',master_password="xxxxxxx", master_log_file='db-01-test-bin.000064',master_log_pos=95854072,master_auto_position=0; ERROR 1794 (HY000): Slave is not configured or failed to initialize properly. You must at least set --server-id to enable either a master or a slave. Additional error messages can be found in the MySQL error log. Solution :- Here It is assumed, We have already set server-id parameter value different on master and slave node but still, we have the above error. It happens once, you performed the server packages upgrade(like from 5.6 to 5.7) and just started MySQL service and going to run CHANGE MASTER command. So, to solve this issue, Run mysql_upgrade command to update/upgrade system tables and then restart M...

ERROR 1040 (HY000): Too many connections

By

ERROR 1040 (HY000): Too many connections An application might face this issue when all the defined max_connections parameter value is exhausted.  mysqld reserve a  +1 connection (i.e., max_connections + 1) for the user who is having the SUPER privilege.  When this issue appears, Only the user with the SUPER privileges can be connected if any other user who has SUPER privileges is not already connected to the database and we have reached max_connections.  1. Always make sure to DON'T give the SUPER privilege to any application user or any user which is being used inside the scripts. Because if that user has already been connected to db when "too many connections" issue appears, then that time root user can't be connected even though root user is having all privileges along with SUPER privileges.  Here I am presenting 3 cases which will help us, how MySQL handles "too many connections" and reserve 1 connection. For below example,...
