docker+Emqx+nginx集群搭建
拉取镜像
docker pull emqx/emqx;
创建虚拟网络
docker network create -d bridge --subnet=172.18.0.0/16 emqx_bridge
启动服务
节点1
docker run -d --hostname emqx01 --name emqx01 --network emqx_bridge --ip 172.18.0.2 -p 60001:1883 -p 60004:8083 -p 60007:8883 -p 60010:8084 -p 60017:18083 -p 60013:11883 -v /etc/localtime:/etc/localtime:ro emqx/emqx:latest;
节点2
docker run -d --hostname emqx02 --name emqx02 --network emqx_bridge --ip 172.18.0.3 -p 60002:1883 -p 60005:8083 -p 60008:8883 -p 60011:8084 -p 60018:18083 -p 60014:11883 -v /etc/localtime:/etc/localtime:ro emqx/emqx:latest;
节点3
docker run -d --hostname emqx03 --name emqx03 --network emqx_bridge --ip 172.18.0.4 -p 60003:1883 -p 60006:8083 -p 60009:8883 -p 60012:8084 -p 60019:18083 -p 60015:11883 -v /etc/localtime:/etc/localtime:ro emqx/emqx:latest
配置集群归属
节点2
docker exec -it emqx02 sh
bin/emqx_ctl cluster join emqx01@172.18.0.2
exit
节点3
docker exec -it emqx03 sh
bin/emqx_ctl cluster join emqx01@172.18.0.2
bin/emqx_ctl cluster status
exit
负载均衡
拉取镜像
Docker pull nginx;
启动项目
docker run --name nginx -p 80:80 -d nginx;
本地映射配置文件
mkdir -p /data/nginx
mkdir -p /data/nginx/www
mkdir -p /data/nginx/conf
mkdir -p /data/nginx/logs
复制配置文件到主机
docker cp 容器id:/etc/nginx/nginx.conf /data/nginx/
docker cp 容器id:/etc/nginx/conf.d /data/nginx/conf/
docker cp 容器id:/usr/share/nginx/html/ /data/nginx/www/
docker cp 容器id:/var/log/nginx/ /data/nginx/logs/
移除之前的服务
docker stop 容器id docker rm 容器id
配置文件编辑
/data/nginx/conf/default.conf此处文件配置不变
/data/nginx/nginx.conf 配置文件进行修改
