k8s快速部署nacos2.2.0集群
精简的nacos集群部署脚本,简化复杂配置。nacos2.2.0集群部署。nacos-headless内部集群端口服务,nacos-service为了方便ingress转发提供给用户web界面操作,requiredDuringSchedulingIgnoredDuringExecution强制反亲和禁止同一个节点部署nacos实列。

1、数据库导入nacos的sql
# 创建数据库
create database nacos_config character set utf8mb4 collate utf8mb4_general_ci;
# 创建用户
create user 'nacos_config'@'%' identified with mysql_native_password by 'nacos_config_db@Yangdouya';
# 授权
grant all privileges on nacos_config.* to 'nacos_config'@'%';
sql脚本mysql-schema.sql
注意不同版本nacos的数据表字段有差异,可以在安装前从git中按照版本获取nacos sql脚本获取地址

注意事项:
1、nacos集群搭建,保证高可用禁止部署在同一个节点,需要配置强制反亲和requiredDuringSchedulingIgnoredDuringExecution
2、集群内部服务地址配置,使用StatefulSet方式部署,将实列编排为xx-0,xx-1, xx-2, xx-n,在配置集群地址上按照 xx-n:acos-headless.default.svc.cluster.local:8848 配置集权dns服务:
name: NACOS_SERVERS
value: “nacos-0.nacos-headless.default.svc.cluster.local:8848 nacos-1.nacos-headless.default.svc.cluster.local:8848 nacos-2.nacos-headless.default.svc.cluster.local:8848”
外部访问(ingress-nginx部署安装,提供外部访问)
部署脚本nacos-deployment.yaml直接下载
完成!
