I am using Terraform v11 to upgrade DB's running on AWS RDS with MySql engine from v5.6 to v5.7.
Each of the DB's has it's own dedicated options group and parameter group.
The upgrade process fails with error:
aws_db_parameter_group.manager: Error deleting DB parameter group: InvalidDBParameterGroupState: One or more database instances are still members of this parameter group foo-rds-mysql56, so the group cannot be deleted
Is there any workaround for this?

I have a mysql cluster with 2 sql nodes, I want to use yii2 to connect this cluster without more coding. It's perfect with Elastich search cluster with a thirth party doing like the bellow:
'elasticsearch' => [
'class' => 'yii\elasticsearch\Connection',
'nodes' => [
['http_address' => '127.0.0.1:9200'],
// configure more hosts if you have a cluster
],
'dslVersion' => 7,
],
How can we do this with a mysql cluster?
after a range time for testing, I have an easy solution want to share for everyone needed.
We just use Yii db replication config, the master's array config is the nodes of mysql ndb cluster, that't it!
[
'class' => 'yii\db\Connection',
// common configuration for masters
'masterConfig' => [
'username' => 'sqlnodeuser',
'password' => 'sqlnodepass',
'attributes' => [
// use a smaller connection timeout
PDO::ATTR_TIMEOUT => 10,
],
],
// list of master configurations
'masters' => [
['dsn' => 'dsn for ndb sql node 1'],
['dsn' => 'dsn for ndb sql node 2'],
],
]
from yii2 official document: https://www.yiiframework.com/doc/guide/2.0/en/db-dao

What am I possibly doing wrong?
Is there a way to obtain a dump (e.g. mysqldump) from an Elasticsearch server (Stage or Production) and then reimport into a local instance running Elasticsearch without using logstash?
This is the same configuration file that works inside an Amazon EC-2 Production Instance but don't know why its not working in my local macOS Mojave instance?
You may encounter the SSL issue of RDS, since
If you use either the MySQL Java Connector v5.1.38 or later, or the MySQL Java Connector v8.0.9 or later to connect to your databases, even if you haven't explicitly configured your applications to use SSL/TLS when connecting to your databases, these client drivers default to using SSL/TLS. In addition, when using SSL/TLS, they perform partial certificate verification and fail to connect if the database server certificate is expired.
as described in AWS RDS Doc
To overcome, either set up the trust store for the LogStash, which is described in the above link as well.
Or take the risk to disable the SSL in the connecting string, like
jdbc_connection_string => "jdbc:mysql://myapp-production.crankbftdpmc.us-west-2.rds.amazonaws.com:3306/products?sslMode=DISABLED"
I'm getting this error "Use of undefined constant SIGKILL - assumed 'SIGKILL'" from my AJAX request, that starts this artisan command ->
Artisan::call('queue:work', [
'connection' => 'database',
'--memory' => '700',

I'm using Laravel 5.7 as framework for application.
Jobs are managed from database, configuration ->

Problem appeared recently.. That is weird, because troubles wasn't here before and all this "system" worked just fine. Now worker get some jobs done just fine, but then it drops to error, and writes to table "failed_jobs" in DB this ->
ErrorException: PDOStatement::execute(): MySQL server has gone away in /srv/migration-xxxxxx-xxxx-xxxxxx/www/vendor/laravel/framework/src/Illuminate/Database/Connection.php:458
As DB I'm using Microsoft Azure MySQL DB. Microsoft specialist after consultation find nothing .. server is working correctly. Queries are just fine, not that big to fail.
Please help, don't know what to do, or what is wrong...
I have a problem on connecting to a mysql datasource from JBoss EAP 6.3 with Teiid 8.10.1 copied over it. I need to mention that I've copied mysql connector driver as a module for using mysql datasource.
Also, when I try with JBoss EAP 6.3 without Teiid, the connection works.
Anybody that confronted the same problem?
This is the error message I receive in administration console of JBoss:
"Unknown error
Unexpected HTTP response: 500
Request {
"address" => [
("subsystem" => "datasources"),
("data-source" => "database")
],
"operation" => "test-connection-in-pool" }
Response
Internal Server Error {
"outcome" => "failed",
"failure-description" => "JBAS010440: failed to invoke operation: JBAS010447: Connection is not valid",
"rolled-back" => true }"
Need to mention that in logs I don't receive a more verbose message for the error, with all logs enabled(Trace, Debug, Error, etc).
In one of my project, I am planning to use ElasticSearch with MySQL.
I have successfully installed ElasticSearch. I am able to manage index in ES separately. but I don't know how to implement the same with MySQL.
I have read a couple of documents but I am a bit confused and not having a clear idea.
As of ES 5.x , they have given this feature out of the box with logstash plugin.
This will periodically import data from database and push to ES server.
One has to create a simple import file given below (which is also described here) and use logstash to run the script. Logstash supports running this script on a schedule.
# file: contacts-index-logstash.conf
input {
jdbc {
jdbc_connection_string => "jdbc:mysql://localhost:3306/mydb"
jdbc_user => "user"
jdbc_password => "pswd"
schedule => "* * * * *"
jdbc_validate_connection => true
jdbc_driver_library => "/path/to/latest/mysql-connector-java-jar"
jdbc_driver_class => "com.mysql.cj.jdbc.Driver"
statement => "SELECT * from contacts where updatedAt > :sql_last_value"
}
}
output {
elasticsearch {
protocol => http
index => "contacts"
document_type => "contact"
document_id => "%{id}"
host => "ES_NODE_HOST"
}
}
# "* * * * *" -> run every minute
# sql_last_value is a built in parameter whose value is set to Thursday, 1 January 1970,
# or 0 if use_column_value is true and tracking_column is set
You can download the mysql jar from maven here.
In case indexes do not exist in ES when this script is executed, they will be created automatically. Just like a normal post call to elasticsearch
Finally i was able to find the answer. sharing my findings.
To use ElasticSearch with Mysql you will require The Java Database Connection (JDBC) importer. with JDBC drivers you can sync your mysql data into elasticsearch.
I am using ubuntu 14.04 LTS and you will require to install Java8 to run elasticsearch as it is written in Java
following are steps to install ElasticSearch 2.2.0 and ElasticSearch-jdbc 2.2.0 and please note both the versions has to be same
after installing Java8 ..... install elasticsearch 2.2.0 as follows
# cd /opt
# wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/deb/elasticsearch/2.2.0/elasticsearch-2.2.0.deb
# sudo dpkg -i elasticsearch-2.2.0.deb
This installation procedure will install Elasticsearch in /usr/share/elasticsearch/ whose configuration files will be placed in /etc/elasticsearch .
Now lets do some basic configuration in config file. here /etc/elasticsearch/elasticsearch.yml is our config file
you can open file to change by
nano /etc/elasticsearch/elasticsearch.yml
and change cluster name and node name
For example :
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: servercluster
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: vps.server.com
#
# Add custom attributes to the node:
#
# node.rack: r1
Now save the file and start elasticsearch
/etc/init.d/elasticsearch start
to test ES installed or not run following
curl -XGET 'http://localhost:9200/?pretty'
If you get following then your elasticsearch is installed now :)
{
"name" : "vps.server.com",
"cluster_name" : "servercluster",
"version" : {
"number" : "2.2.0",
"build_hash" : "8ff36d139e16f8720f2947ef62c8167a888992fe",
"build_timestamp" : "2016-01-27T13:32:39Z",
"build_snapshot" : false,
"lucene_version" : "5.4.1"
},
"tagline" : "You Know, for Search"
}
Now let's install elasticsearch-JDBC
download it from http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/2.3.3.1/elasticsearch-jdbc-2.3.3.1-dist.zip and extract the same in /etc/elasticsearch/ and create "logs" folder also there ( path of logs should be /etc/elasticsearch/logs)
I have one database created in mysql having name "ElasticSearchDatabase" and inside that table named "test" with fields id,name and email
cd /etc/elasticsearch
and run following
echo '{
"type":"jdbc",
"jdbc":{
"url":"jdbc:mysql://localhost:3306/ElasticSearchDatabase",
"user":"root",
"password":"",
"sql":"SELECT id as _id, id, name,email FROM test",
"index":"users",
"type":"users",
"autocommit":"true",
"metrics": {
"enabled" : true
},
"elasticsearch" : {
"cluster" : "servercluster",
"host" : "localhost",
"port" : 9300
}
}
}' | java -cp "/etc/elasticsearch/elasticsearch-jdbc-2.2.0.0/lib/*" -"Dlog4j.configurationFile=file:////etc/elasticsearch/elasticsearch-jdbc-2.2.0.0/bin/log4j2.xml" "org.xbib.tools.Runner" "org.xbib.tools.JDBCImporter"
now check if mysql data imported in ES or not
curl -XGET http://localhost:9200/users/_search/?pretty
If all goes well, you will be able to see all your mysql data in json format
and if any error is there you will be able to see them in /etc/elasticsearch/logs/jdbc.log file
Caution :
In older versions of ES ... plugin Elasticsearch-river-jdbc was used which is completely deprecated in latest version so do not use it.
I hope i could save your time :)
Any further thoughts are appreciated
Reference url : https://github.com/jprante/elasticsearch-jdbc
The logstash JDBC plugin will do the job:
input {
jdbc {
jdbc_connection_string => "jdbc:mysql://localhost:3306/testdb"
jdbc_user => "root"
jdbc_password => "factweavers"
# The path to our downloaded jdbc driver
jdbc_driver_library => "/home/comp/Downloads/mysql-connector-java-5.1.38.jar"
jdbc_driver_class => "com.mysql.jdbc.Driver"
# our query
schedule => "* * * *"
statement => "SELECT" * FROM testtable where Date > :sql_last_value order by Date"
use_column_value => true
tracking_column => Date
}
output {
stdout { codec => json_lines }
elasticsearch {
"hosts" => "localhost:9200"
"index" => "test-migrate"
"document_type" => "data"
"document_id" => "%{personid}"
}
}
To make it more simple I have created a PHP class to Setup MySQL with Elasticsearch. Using my Class you can sync your MySQL data in elasticsearch and also perform full-text search. You just need to set your SQL query and class will do the rest for you.
