复制端口步骤
copy configuration
name: 9011
vm options: -DServer.port=9011

http://localhost:9001/payment/nacos/1
http://localhost:9011/payment/nacos/1
http://localhost:83/consumer/payment/nacos/11
#切换成CP模式
curl -X PUT '$NACOS_SERVER:8848/nacos/v1/ns/operator/switches?entry=serverMode&value=CP'

# ${spring.application.name}-${spring.profile.active}.${spring.cloud.nacos.config.file-extension}
# nacos-config-client-dev.yaml

http://localhost:3377/config/info

默认情况:Name    space=public,Group=DEFAULT_GROUP,默认Cluster是DEFAULT。

nacos-server-1.1.4
新建nacos_config数据库，脚本在对应config目录下。

application.properties增加内容：

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=root

修改cluster.conf文档
192.168.0.211:3333
192.168.0.211:4444
192.168.0.211:5555

命令： ./startup.sh -p 3333

修改startup.sh
while getopts ":m:f:s:c:p:" opt
        p)
            #EMBEDDED_STORAGE=$OPTARG;;
            PORT=$OPTARG;;
nohup "$JAVA" -Dserver.port=${PORT}


修改nginx对应配置
/usr/local/nginx/conf/nginx.conf
新版不一样（可能是指定安装位置的）。

配置文件位置
主配置文件：/etc/nginx/nginx.conf
虚拟主机配置：/etc/nginx/conf.d/目录下的 .conf文件

修改/etc/nginx/conf.d/default.conf文档
upstream cluster{
    server 127.0.0.1:3333;
    server 127.0.0.1:4444;
    server 127.0.0.1:5555;
}
server{
    listen        1111;
    server_name   localhost; 
    location / {
        #root   /usr/share/nginx/html;
        #index  index.html index.htm;
        proxy_pass http://cluster;
    }

}

/usr/local/nginx/sbin目录下运行下面一行
./nginx -C /usr/local/nginx/conf/nginx.conf


ps -ef |grep nacos |grep -v grep |wc -l
