Docker搭建Nacos集群
一、Centos7安装Docker
//1.查看操作系统的发行版号
uname -r
//2.安装依赖软件包
yum install -y yum-utils device-mapper-persistent-data lvm2
//3.设置yum镜像源
//官方源(慢)
yum-config-manager --add-repo http://download.docker.com/linux/centos/docker-ce.repo
//阿里源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
//清华大学源
yum-config-manager --add-repo https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
//4.查看docker版本
yum list docker-ce --showduplicates | sort -r
//5.默认安装最新版本
yum -y install docker-ce
二、设置Docker阿里云镜像加速
1.阿里云选择容器镜像服务
注意事项:registry-mirrors 每个人的地址是不一样的
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://rsmi26wc.mirror.aliyuncs.com"]
}
EOF
三、Docker部署Nacos集群
1、准备工作

2、Docker安装Nacos(这里我使用的是VMware的虚拟机三台机器128、129、130)
在128和129两台机器上分别使用docker拉去Nacos的镜像
docker pull nacos/nacos-server
分别在两台机器上运行容器
//在128机器上运行
docker run -itd -e PREFER_HOST_MODE=ip \
-e MODE=cluster \
-e NACOS_SERVERS="192.168.32.128:8848 192.168.32.129:8848" \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=你的数据库ip地址 \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_DB_NAME=nacos_conf \
-e MYSQL_SERVICE_USER=nacos_conf \
-e MYSQL_SERVICE_PASSWORD=adminadmin \
--network host \
--name nacos-128\
--restart=always \
-d bdf60dc2ada3
//在129机器上运行
docker run -itd -e PREFER_HOST_MODE=ip \
-e MODE=cluster \
-e NACOS_SERVERS="192.168.32.128:8848 192.168.32.129:8848" \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=你的数据库ip地址 \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_DB_NAME=nacos_conf \
-e MYSQL_SERVICE_USER=nacos_conf \
-e MYSQL_SERVICE_PASSWORD=adminadmin \
--network host \
--name nacos-129\
--restart=always \
-d bdf60dc2ada3
参数详情可以查看官方文档
Nacos文档
参数 | 描述 | |
---|---|---|
PREFER_HOST_MODE | 支持IP还是域名模式 | hostname/ip 默认 ip |
MODE | 系统启动方式: 集群/单机 | cluster/standalone默认 cluster |
NACOS_SERVERS | 集群地址 | p1:port1空格ip2:port2 空格ip3:port3 |
SPRING_DATASOURCE_PLATFORM | 支持MYSQL数据库 | mysql / 空 默认:空 |
MYSQL_SERVICE_HOST | 数据库ip地址 | 数据库 连接地址 |
MYSQL_SERVICE_DB_NAME | 数据库名称 | 名称 |
MYSQL_SERVICE_USER | 数据库用户名 | 数据库用户名 |
MYSQL_SERVICE_PASSWORD | 数据库密码 | 密码 |
–network | 网络设置 | 容器与宿主共用网络 |
–name | 容器名称 | 容器名称 |
–restart | 重启策略 | 退出时总是重启 |
-d | 后台运行 | 后台运行 |
3、测试成功
四、Nginx代理Nacos集群地址(配置统一访问地址)
1、在192.168.32.130机器上搭建Nginx代理
//1、拉取nginx镜像
docker pull nginx
//2、在宿主机上新建目录 与docker nginx镜像做文件映射
mkdir -p /home/nginx/{conf,html,log}
//3、启动nginx容器
docker run -d --name nginx nginx
//4、copy容器配置文件到宿主机上
docker cp nginx:/etc/nginx/conf.d /home/nginx/conf
docker cp nginx:/etc/nginx/nginx.conf /home/nginx/conf/nginx.conf
docker cp nginx:/usr/share/nginx/html/index.html /home/nginx/html/index.html
//5、停止nginx容器并删除该临时容器
docker stop nginx
docker rm nginx
//6、启动nginx容器
docker run -p 8848:8848 -p 80:80 \
--name nginx \
-v /home/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /home/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /home/nginx/log:/var/log/nginx \
-v /home/nginx/html:/usr/share/nginx/html \
-d 605c77e624dd
//7、新增nginx配置文件
vi /home/nginx/conf/conf.d/nacos.conf
upstream nacos {
server 192.168.32.128:8848;
server 192.168.32.129:8848;
}
server {
listen 8848;
server_name 192.168.32.130;
location / {
proxy_pass http://nacos;
}
}
注意事项:不要忘记在开放防火墙端口
//查看开发的端口
firewall-cmd --zone=public --list-ports
//添加开放端口
firewall-cmd --zone=public --add-port=8848/tcp --permanent
//重启防火墙
firewall-cmd --reload
2、测试192.168.32.130:8848
Nacos默认账号密码为 nacos/nacos
