标签:dubbo Spring spring nacos 192.168 demo cloud

环境
  nacos-2.2.0
  Spring Cloud-2.1.2.RELEASE
  CentOS Linux release 7.9.2009 (Core)
  部署三台虚拟机IP:192.168.6.102:8848,192.168.6.103:8848,192.168.6.104:8848

一、部署nacos
1、下载、编译nacos

#下载代码 这里下载2.2.0版本
git clone -b 2.2.0 https://github.com/alibaba/nacos.git
#构建
cd nacos/
mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U 
#查看构建结果
ls -al distribution/target/
cd distribution/target/nacos-server-2.2.0/nacos/

 将distribution/target/nacos-server-2.2.0 下nacos上传到服务器即可

  2、数据库配置

(1)mysql创建UTF8数据的数据库:nacos_config,然后使用navicat接连该数据库执行脚本:nacos/conf/mysql-schema.sql

(2)修改nacos数据库连接:nacos/conf/application.properties

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:  如果使用mysql 开启这一行注释
spring.datasource.platform=mysql

### Count of DB:
db.num=1

### Connect URL of DB:
db.url.0=jdbc:mysql://node102:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=123456

3、集群配置 

复制一份集群配置文件:cp nacos/conf/cluster.conf.example nacos/conf/cluster.conf

#2023-01-12T11:24:11.094
192.168.6.102:8848
192.168.6.103:8848
192.168.6.104:8848

4、启停

#启动
[root@node104 bin]# sh ./startup.sh
/usr/local/jdk1.8.0_271/bin/java -Djava.ext.dirs=/usr/local/jdk1.8.0_271/jre/lib/ext:/usr/local/jdk1.8.0_271/lib/ext  -server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/usr/local/nacos/logs/java_heapdump.hprof -XX:-UseLargePages -Dnacos.member.list= -Xloggc:/usr/local/nacos/logs/nacos_gc.log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M -Dloader.path=/usr/local/nacos/plugins,/usr/local/nacos/plugins/health,/usr/local/nacos/plugins/cmdb,/usr/local/nacos/plugins/selector -Dnacos.home=/usr/local/nacos -jar /usr/local/nacos/target/nacos-server.jar  --spring.config.additional-location=file:/usr/local/nacos/conf/ --logging.config=/usr/local/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288
nacos is starting with cluster
nacos is starting,you can check the /usr/local/nacos/logs/start.out
#停止
[root@node104 bin]# sh ./shutdown.sh
The nacosServer(1826) is running...
Send shutdown request to nacosServer(1826) OK

5、控制台

http://192.168.6.102:8848/nacos/    用户名/密码:nacos/nacos
http://192.168.6.103:8848/nacos/    用户名/密码:nacos/nacos
http://192.168.6.104:8848/nacos/    用户名/密码:nacos/nacos

 

 

二、集成dubbo

 

 0、代码模块整体pom
