配置叢集歸屬
節點2
docker exec -it emqx02 sh
bin/emqx_ctl cluster join [email protected]
exit
節點3
docker exec -it emqx03 sh
bin/emqx_ctl cluster join [email protected]
bin/emqx_ctl cluster status
exit
負載均衡
拉取映象
Docker pull nginx;
啟動專案
docker run --name nginx -p 80:80 -d nginx;
本地對映配置檔案
mkdir -p /data/nginx
mkdir -p /data/nginx/www
mkdir -p /data/nginx/conf
mkdir -p /data/nginx/logs
複製配置檔案到主機
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/
移除之前的服務
docker stop 容器id docker rm 容器id
配置檔案編輯
/data/nginx/nginx.conf 此處檔案配置不變
/data/nginx/conf/default.conf配置檔案進行修改

啟動檔案
docker run --name nginx -p 80:80 --network emqx_bridge --ip 172.18.0.6 -v /data/nginx/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/www/:/usr/share/nginx/html/ -v /data/nginx/logs/:/var/log/nginx/ -v /data/nginx/conf/:/etc/nginx/conf.d --privileged=true -d nginx
