Docker nginx安裝與配置掛載

• 在Docker下載Nginx映象

docker pull nginx
docker images

• 建立掛載目錄

mkdir -p /data/nginx/{conf,conf.d,html,logs}

• 編寫nginx,conf配置檔案，並放在資料夾中

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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;

    include             /etc/nginx/mime.types;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include

    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  182.254.161.54;

        include /etc/nginx/default.d/*.conf;

        location / {
        proxy_pass http://pic; 
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

    upstream pic{
                server 182.254.161.54:8088 weight=5;
                server 182.254.161.54:8089 weight=5;
    }

}

• 啟動容器

docker run --name mynginx -d -p 82:80  -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf  -v /data/nginx/logs:/var/log/nginx -d docker.io/nginx

• 檢視啟動的容器

docker ps 

• 先前已經在Docker部署兩個tomcat，一個是8088埠，另一個是8089埠，並進入兩個容器裡編寫了簡單的頁面

訪問8088埠

訪問8089埠

• 現在通過Nginx訪問兩個tomcat的內容，實現負載均衡的功能，出於區別，更能體現負載均衡的功能，兩個頁面的內容不一樣，但是訪問路徑都一樣，只是通過Nginx反向代理去輪換訪問
