Preface ：

MySQL It is the middleware of microservice business application , It's also a microservice , It can be deployed separately , Follow the basic process of microservice deployment .

The first 1 Step ： precondition

1.1 stay Kubesphere Select project space （ Namespace ）

1.2  stay dockerhub find MySQL Required configuration parameters for deployment

（1）docker hub Home page

Docker Hub

（2）search “mysql”

https://hub.docker.com/_/mysql

$ docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

#  Expose profile 
$ docker run --name some-mysql -v /my/custom:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

mysql It is not accessed arbitrarily , User name required + Password authentication .

therefore ,mysql The startup of the needs to be accessed through the setting of environment variables mysql Password .

1.3 MySql server Deployment planning

•  PVC be used for MySql Use on the outside of the container （ Write ） Persistence MySql Of Business data
• ConfigMap be used for MySql In the container external Use （ read ） The configuration file

1.4 Pre created outside the microservice PVC Persistent volume

 

1.5 Pre created outside the microservice MySQL Configuration file for

 MySQL There is a lot of configuration information , We can choose several experiments ：

[client]

port = 3306
default-character-set = utf8mb4

[mysql]
default-character-set = utf8mb4

[mysqld]

The first 2 Step ： Deploy mysql Microservices

2.1 Install container image

 

 

 

 

2.2 Hang on external persistent volumes

2.3 Mount external configuration file

2.4 Check the image installation

 

 

step 3： by mysql establish Service service object

3.1 establish clusterIP service object （ Only internal cluster access ）

Get into Service, Access by service name MySQL service ： 

mysql -u root -h his-mysql-glgf.his -p

123456

3.2  establish NodePort service object （ It can be accessed through the public network MySQL service ）

 

Outside the cluster （ Public network host ）, adopt mysql Client access MySQL service

• Install client in advance

MySQL :: Download MySQL Workbench

• Access password ：123456  （ Install the password set through the environment variable ）
