一、单机部署

1.1、环境依赖

• 64 bit OS，支持 Linux/Unix/Mac/Windows，推荐选用 Linux/Unix/Mac
• 64 bit JDK 1.8+；
• Maven 3.2.x+；

# 版本自己挑: https://github.com/alibaba/nacos/releases
[root@nacos ~]# wget https://github.com/alibaba/nacos/releases/download/2.0.0-bugfix/nacos-server-2.0.0.tar.gz

1.3、部署

[root@nacos ~]# tar -xvf nacos-server-2.0.0.tar.gz -C /app/

1.4、单机启动

[root@nacos ~]# cd /app/nacos/bin/
[root@nacos bin]# sh startup.sh -m standalone

1.5、验证

[root@nacos ~]# tail -f /app/nacos/logs/start.out

# 端口校验
[root@nacos conf]# ss -ntl  | grep 8848

1.6、页面访问

http://192.168.1.55:8848/nacos/

默认账号密码：nacos/nacos

1.7、OPENAPI验证

# 服务注册
[root@nacos ~]# curl -X PUT 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080'
caused: service not found, namespace: public, service: Service{namespace='public', group='DEFAULT_GROUP', name='nacos.naming.serviceName', ephemeral=true, revision=0};

# 服务发现
[root@nacos ~]# curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=nacos.naming.serviceName'
{"name":"DEFAULT_GROUP@@nacos.naming.serviceName","groupName":"DEFAULT_GROUP","clusters":"","cacheMillis":10000,"hosts":[],"lastRefTime":1629164329309,"checksum":"","allIPs":false,"reachProtectionThreshold":false,"valid":true}

# 发布配置
[root@nacos ~]# curl -X POST "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=helloWorld"
true

# 获取配置
[root@nacos ~]# curl -X GET "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test"
helloWorld

1.8、关闭

[root@nacos bin]# sh shutdown.sh
The nacosServer(20159) is running...
Send shutdown request to nacosServer(20159) OK

1.9、外部MySQL数据库支持

• 版本要求：5.6.5+ ，mysql 8 以下 （自行安装）
• 初始化mysql数据库，新建数据库nacos_config，数据库初始化文件 /app/nacos/conf/nacos-mysql.sql
• 修改/conf/application.properties文件

# 1、创建数据库
CREATE DATABASE IF NOT EXISTS nacos_devtest CHARACTER SET utf8;

# 2、导入nacos-mysql.sql
use nacos_devtest
source  /app/nacos-mysql.sql

• 修改配置文件,末尾增加

[root@nacos conf]# vim /app/nacos/conf/application.properties
spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://192.168.1.208:3306/nacos_devtest?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=username
db.password=password

1.10、再次启动

[root@nacos ~]# cd /app/nacos/bin/
[root@nacos bin]# sh startup.sh -m standalone
