[Solved] Nacos2.1.1 Startup Error: nacos is starting with standalone

Project Scene:

Developing a microservice project, requires the service registration and configuration center. The development and application of Nacos technology. The native OS is Windows11, Nacos version is 2.1.1 installed on Drive D.

Problem description

Nacos start：

Double-click startup.cmd in the bin directory and it will flash back, that is, the startup failed;

Use the command to start: startup.cmd -m standalone, An error message appears

D:\Program Files (x86)\nacos-server-2.1.1\nacos\bin>startup.cmd -m standalone
"nacos is starting with standalone"
There should be no \nacos-server-2.1.1\nacos"\logs\java_heapdump.hprof -XX:-UseLargePages" at this point.

Solution：

The first solution: unzip Nacos to a directory does not contain non-English and numbers, Command line started successfully

Second solution: Open startup with editor, Comment out the content shown below：

rem if %MODE% == "cluster" (
rem echo "nacos is starting with cluster"
rem if %EMBEDDED_STORAGE% == "embedded" (
rem set "NACOS_OPTS=-DembeddedStorage=true"
rem )

rem set "NACOS_JVM_OPTS=-server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX: HeapDumpPath=%BASE_DIR%\logs\java_heapdump.hprof -XX:-UseLargePages"
rem )

Not sure if this solution will cause other problems, but it starts fine

[Solved] Nacos1.3.2 Startup Error: Unable to start embedded Tomcat

Recently, I started to plan to learn springcloud-alibaba, so I downloaded the Nacos installation package on the GitHub official website, and found an error on startup.

Error message: Unable to start embedded Tomcat
the built-in Tomcat cannot be loaded.

Opened the conf folder and saw a nacos-mysql.sql
It seems to import a database script, so I created a database named nacos in the local database
and executed this sql script, which generated some tables.

With a database and tables, we must change the configuration.
So I opened application.properties with an editor
I saw that there is a place to configure the db, so I changed it.

After saving
enter the bin directory again and double-click startbat.cmd to start.

I found that I still reported an error.

Caused by: java.net.UnknownHostException: jmenv.tbsite.net

Here I have changed the configuration file again, but it has no effect.

The key point is that during startup, I noticed a message,
Nacos has been started in cluster mode. Cluster list is []

I wonder if this is the problem, because I clicked run and did not configure the Nacos cluster.

So I use the editor to open the startup.cmd in the dictory bin
see a key message

Here you can configure click mode startup, so try to change the startup configuration to click mode startup

Exit after saving. Double click the startup file startup.cmd

It started normally this time.

Enter in Browser: localhost:8848/nacos/index.html

Normally access the Nacos configuration center.

[Solved] Kafka Error: kafka.common.InconsistentClusterIdException…

1. Background

Kafka’s physical machine is unexpectedly down, resulting in Kafka’s failure to start

2. Details of error report

[2022-08-09 08:20:42,097] ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
kafka.common.InconsistentClusterIdException: The Cluster ID 123456 doesn't match stored clusterId Some(456789) in meta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong.
	at kafka.server.KafkaServer.startup(KafkaServer.scala:235)
	at kafka.server.KafkaServerStartable.startup(KafkaServerStartable.scala:44)
	at kafka.Kafka$.main(Kafka.scala:82)
	at kafka.Kafka.main(Kafka.scala)

3. Solution

It can be seen that the error is obvious. The cluster-id is not correct. At this time, we can modify the configuration of meta.properties

# The location of the meta.properties file can be found based on the value of the log.dirs parameter in the server.properties configuration file
vim meta.properties

cluster.id=123456

Then it can be started normally

[Solved] Hadoop Error: ERROR: Cannot set priority of namenode process

Phenomenon:

solve:

1. Look at Hadoop logs:

Check the namenode log: tail -n 200 hadoop-xinjie-namenode-VM-0-9-centos.log (location of file directory: Hadoop installation location logs file)

2. It is found that the port is occupied

3. Command to check the port occupancy: netstat -anp|grep 9866

4. Kill process: kill -9 9866

5. Restart the cluster after killing all the occupied ports. The problem is solved

Zookeeper Failed to Start Error: start failed [How to Solve]

=====There is no error prompt in ZK here. Look for the logs. There is a logs directory on the upper layer of the bin directory. Check the logs===

Main error log information:

2022-07-28 15:31:50,793 [myid:] - ERROR [main:QuorumPeerMain@98] - Invalid config, exiting abnormally

========Solution information========

cd apache-zookeeper-3.6.2-bin/conf/

View the VIM zoo configuration file, view the dataDir directory defined by yourself, and view the ID information of zkServer.

CD to the dataDir directory,

echo “serverid” > myid

Go to the bin directory and start again, sh zkServer.sh start
check ZK application status: sh zkServer.sh status, (if the startup is successful and the status is wrong, you can wait until the cluster machine starts completely).

========================End=====================

[Solved] Win 10 Kafka error: failed to construct Kafka consumer

After updating the code, the package succeeds, but an error is reported when the project is started. The error information is shown in the following figure:

I mean, it is obvious that the problem lies in Kafka. After looking at the configuration, it should be the port problem.

Instead of using IP configuration, I directly configured the port name in the host file, as shown in the following figure:

Add configuration 127.0.0.1 Kafka-server

Then change the service address of Kafka to kafka-server:9092 in the application configuration file of the project

[Solved] RabbitMQ Error: Error creating bean with name ‘rabbitConnectionFactory‘ defined in class path resource

1. Error Messages:

Error creating bean with name 'rabbitConnectionFactory' defined in class path resource [org/springframework/boot/autoconfigure/amqp/RabbitAutoConfiguration$RabbitConnectionFactoryCreator.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.amqp.rabbit.connection.CachingConnectionFactory]: Factory method 'rabbitConnectionFactory' threw exception; nested exception is java.lang.IllegalArgumentException: Address 192.168.74.128:5672:5672 seems to contain an unquoted IPv6 address. Make sure you quote IPv6 addresses like so: [2001:db8:85a3:8d3:1319:8a2e:370:7348]

2. Reason
Address 192.168.74.128:5672:5672 seems to contain an unquoted IPv6 address. Make sure you quote IPv6 addresses like so: [2001:db8:85a3:8d3:1319:8a2e:370:7348]
Identified as ipv6, rabbitmq should also support IPV6

3. Solution
application.yml File

 rabbitmq:
  #host: 192.168.74.128:5672//去掉端口
  host: 192.168.74.128
  username: admin
  password: 123123
  virtual-host: /
