docker 部署后端项目nginx负载均衡

1,拉取镜像

docker pull java

2,创建docker卷

docker volume create j1

3,运行容器

docker run -it -d --name j1 -v j1:/home/soft --net=host java

之所以要用主机的网段，是为了让项目能连上docker容器内其他主机的网络。

4,上传jar文件到卷位置

1，查看卷位置 docker volume inspect j1 2，上传

5,进入容器内部运行jar

docker exec -it j1 bash nohup java -jar /home/soft/renren-fast.jar

6,创建同样两个容器

docker volume create j2 docker volume create j3 docker run -it -d --name j2 -v j2:/home/soft --net=host java docker run -it -d --name j3 -v j3:/home/soft --net=host java ##分别上传修改完端口后的项目到这两个容器中 ..... docker exec -it j2 bash nohup java -jar /home/soft/renren-fast.jar docker exec -it j3 bash nohup java -jar /home/soft/renren-fast.jar

7,拉取nginx

docker pull nginx

8,上传nginx配置文件

宿主机上/home/nginx/nginx.conf配置文件内容如下

user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } 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; #tcp_nopush on; keepalive_timeout 65; #gzip on; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 5s; proxy_send_timeout 5s; proxy_read_timeout 5s; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; upstream tomcat { server 123.207.72.15:8081; server 123.207.72.15:8082; server 123.207.72.15:8083; } server { listen 6101; server_name 123.207.72.15; location / { proxy_pass http://tomcat; index index.html index.htm; } } }

9,启动nginx

docker run -it -d --name n1 -v /home/nginx/nginx.conf:/etc/nginx/nginx.conf --net=host --privileged nginx
