集群部署nacos

三台服务器

主机系统	主机IP
almaLiunx	10.1.0.108
almaLiunx	10.1.0.109
almaLiunx	10.1.0.112

需要提前准备数据库

下面的操作，每个主机都要做

安装依赖

dnf install java-11-openjdk-devel

下载安装包

wget https://github.com/alibaba/nacos/releases/download/2.5.1/nacos-server-2.5.1.tar.gz

修改配置

vim conf/application.properties
# 修改下面的配置
spring.sql.init.platform=mysql

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

### Connect URL of DB:
db.url.0=jdbc:mysql://10.1.0.108:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=Asia/Shanghai
db.user.0=admin
db.password.0=111111

nacos.core.auth.enabled=true
### Since 1.4.1, worked when nacos.core.auth.enabled=true and nacos.core.auth.enable.userAgentAuthWhite=false.
### The two properties is the white list for auth and used by identity the request from other server.
nacos.core.auth.server.identity.key=abc
nacos.core.auth.server.identity.value=111

### The default token (Base64 String):
nacos.core.auth.plugin.nacos.token.secret.key=MTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExCg==

这就表示成功了
然后可以访问
http://10.1.0.108:8848/nacos
http://10.1.0.109:8848/nacos
http://10.1.0.112:8848/nacos

前面可以加个LB

这里就可以看到，集群已经正常了
