Nacos集群搭建

1.集群结构图

官方给出的Nacos集群图：

compose docker 集群部署 docker-compose nacos集群_1024程序员节

其中包含3个nacos节点，然后一个负载均衡器代理3个Nacos。这里负载均衡器可以使用nginx。

我们计划的集群结构：

compose docker 集群部署 docker-compose nacos集群_修改时间_02

2.搭建集群

1.前置准备：docker、nacos的数据库

MySQL安装可以查看应用部署的内容进行安装，这里不进行重复了

INSERT INTO roles (username, role) VALUES ('nacos', 'ROLE_ADMIN');

2.创建nacos目录

mkdir -p /apps/nacos

最总文件目录结构如下：

compose docker 集群部署 docker-compose nacos集群_表名_03

3、切换到nacos目录下，创建并写nginx.conf配置文件

①切换到nacos目录

cd /apps/nacos

②创建nginx配置文件

touch nginx.conf

③写nginx.conf文件信息

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  4096;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;

    # include /etc/nginx/conf.d/*.conf;
    # 添加负载均衡配置
    upstream nacos {
        server 192.168.43.128:8846 weight=1 max_fails=2 fail_timeout=10s;# 192.168.43.128是宿主机的ip，因为nacos容器安装好后就是通过宿主机ip:端口访问的
        server 192.168.43.128:8847 weight=1 max_fails=2 fail_timeout=10s;
        server 192.168.43.128:8849 weight=1 max_fails=2 fail_timeout=10s;
    }

    server {
        listen       80;
        listen  [::]:80;
        # 修改为宿主机的 IP地址
        server_name 192.168.43.128;


        # To allow special characters in headers
        ignore_invalid_headers off;
        # Allow any size file to be uploaded.
        # Set to a value such as 1000m; to restrict file size to a specific value
        client_max_body_size 0;
        # To disable buffering
        proxy_buffering off;
        proxy_request_buffering off;

        location /nacos {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;

            proxy_connect_timeout 300;
            # Default is HTTP/1, keepalive is only enabled in HTTP/1.1
            proxy_http_version 1.1;
            proxy_set_header Connection "";
            chunked_transfer_encoding off;
            # 添加代理配置

            proxy_pass http://nacos;
        }
    }
}

4、创建并写docker-compose.yaml配置文件

切换到nacos目录

cd /apps/nacos

创建docker-compose.yaml文件

touch docker-compose.yaml

写docker-compose.yaml文件信息

vim docker-compose.yaml

以下为docker-compose.yaml内容,注意MYSQL_SERVICE_*相关为数据库配置,nacos-nginx的volumes为挂载读取同目录下的nginx.conf配置

version: "3"
services: 
    nacos-nginx: 
        container_name: nacos-nginx

        hostname: nacos-server02
        image: nacos/nacos-server
        environment: 
            - MODE=cluster
            - PREFER_HOST_MODE=hostname
            - NACOS_SERVERS=nacos-server01:8848 nacos-server02:8848 nacos-server03:8848

        ports: 
            - 8847:8848
            - 9849:9848
        restart: on-failure

    nacos3:
        container_name: nacos-server03
        hostname: nacos-server03
        image: nacos/nacos-server
        environment: 
            - MODE=cluster
            - PREFER_HOST_MODE=hostname
            - NACOS_SERVERS=nacos-server01:8848 nacos-server02:8848 nacos-server03:8848

            - 8849:8848
            - 9850:9848
        restart: on-failure

5、编排docker-compose.yaml

编排docker-compose.yaml

#语法 docker-compose -f <编排文件路径> up -d
docker-compose -f docker-compose.yaml up -d

查看运行情况

docker ps -n 5
