21-[信创]-Nacos使用docker-compose方式部署nacos集群_表名

一、数据库初始化

自己下载或者使用下面的都可以

wget https://raw.githubusercontent.com/alibaba/nacos/master/distribution/conf/mysql-schema.sql

[root@redis-nacos data]# vim mysql-scheme.sql

三、配置NGINX

[root@nginx01 ~]# cat /data/nginx/conf/vhost/nacos.aqsc.com.conf 
upstream nacos-http {
    ip_hash;
    server 10.1.19.73:8848;
    server 10.1.19.73:2258;  # 其他节点统一使用 8848 端口
    server 10.1.19.73:3368;
}

server {
    listen 8848;
    server_name nacos.aqsc.com;

    location /nacos {
        proxy_pass http://nacos-http/nacos;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

server {
    listen 9848;
    proxy_pass nacos-grpc;
}
