Kubesphere - build Nacos cluster

One 、KubeSphere - build nacos colony

In the last article, we passed the experiment KubeSphere stay k8s Build in a cluster elasticsearch colony And Visualization tools kibana, In this article, let's experiment together adopt KubeSphere stay k8s Build in a cluster nacos colony , Here is the address of the last article ：

Before the experiment , Please make sure that the installation is complete k8s And kubesphere Environmental Science ：

Here we built nacos It mainly stores data in mysql in , Therefore, it should be installed in advance before the experiment mysql service . Please refer to my blog below ：

https://blog.csdn.net/qq_43692950/article/details/122819844

Above I created a is headless Service for , stay k8s The interior can provide a stable DNS domain name , One is nodeport , A peripheral release port is provided to facilitate mysql To operate . Here mine DNS by ：mysql.test-project.

We need to build naocs:2.0.3 Version of cluster , It is best to download the official installation package before starting , The configuration documents and SQL We can get and modify the file directly , Download address ：

https://github.com/alibaba/nacos/releases/tag/2.0.3

among config The file under is what we need to use below ：

First, create a... In the database nacos_config database , And implement config In the catalog nacos-mysql.sql：

Two 、 establish application.properties、cluster.conf Prepare a dictionary

modify config In the catalog application.properties file , The specified storage mode is mysql, And designate mysql Link to ：

stay kubesphere Create a configuration dictionary in ：

After the next step , Add data , The key is ：application.properties, Value just copy the contents of the above file ：

Then add another data , The key is ：cluster.conf, Next, we specify both the service name and the container name as nacos, Version is v1 edition , So the value can be written as follows ：

nacos-v1-0.nacos.test-project.svc.cluster.local:8848
nacos-v1-1.nacos.test-project.svc.cluster.local:8848
nacos-v1-2.nacos.test-project.svc.cluster.local:8848

3、 ... and 、 establish nacos service

Select Create stateful service ：

The service name is specified as nacos ：

The number of containers is specified as 3：

The following image is used nacos/nacos-server:v2.0.3 edition , And use the default port ：

The following environment variable specifies JVM Size , It depends on the size of your server , Here just set JVM_XMS、JVM_XMX、JVM_XMN：

And then the next step , Then mount the two configuration files created above ：

among application.properties Mount to ：/home/nacos/conf/application.properties,
cluster.conf Mount to ：/home/nacos/conf/cluster.conf.

All sub paths should be specified here , Otherwise, other files in this path cannot be found ：

Specify a specific key ：

The following is prepared in the same way cluster.conf：

Click next below , establish .

Click the service to go in and see the created container ：

Enter one at random nacos Log , You can see that the cluster has been initialized .

Four 、 by nacos Create a NodePort Service for

Now? nacos Only then k8s Only in the cluster can access , In the cluster, I can use headless Load access , You can also build another nginx, But none of this allows us to visit outside , So here we need to create another nodeport Service for , You can access nacos.

Select the specified workload ：

Name the service ：

Then specify the workload here ：

Then select the one you just created nacos service ：

Port we choose 8848 port ：

And then the next step , Select external access ,NodePort Pattern ：

Finally create , Click this service to enter details , You can see the released port ：

Now visit in the browser ：http://192.168.40.130:30797/nacos

Use nacos/nacos Sign in ：
