昨天部署了nginx+php+mysql，今天编排一个常见的高性能web服务器，是通过nginx反向代理tomcat
我们直接就上下编排文件试试吧，看能不能一次性通过
以下操作都再/data目录下操作，我们先创建需要的目录

sudo mkdir -p /data/{nginx/etc/,logs/nginx,/www,logs/tomcat}

version: "2.0"
services:
  nginx:
    image: nginx:latest
    restart: always
    ports:
      - 80:80
    depends_on:
      - tomcat
    volumes:
      - ./nginx/etc/nginx.conf:/etc/nginx/nginx.conf:ro
      - ./logs/nginx:/var/log/nginx:rw
    networks:
      - app_net
    container_name: app-nginx
  tomcat:
    image: tomcat:latest
    restart: always
    ports:
      - 8080:8080
    volumes:
      - ./www:/usr/local/tomcat/webapps:rw
      - ./logs/tomcat:/usr/local/tomcat/logs:rw
    networks:
      - app_net
    container_name: app-tomcat
networks:
  app_net:
    driver: bridge

nginx配置

sudo vim /data/nginx/etc/nginx.conf

user  nginx;
worker_processes  auto;
error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;
events {
    worker_connections  1024;
    multi_accept on; 
    use epoll; 
}
http {
    include       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;
    client_header_timeout 30; 
    client_body_timeout 30;
    client_max_body_size 128m;
    reset_timedout_connection on;
    sendfile        on;

    keepalive_timeout  30;
    
    send_timeout 30;
    limit_conn_zone $binary_remote_addr zone=addr:5m; 
    limit_conn addr 100;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    fastcgi_buffer_size 128k;
    fastcgi_buffers 4 256k;
    fastcgi_busy_buffers_size 256k;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 16 64k;
    gzip_http_version 1.1;
    gzip_comp_level 9;
    gzip_types text/plain application/x-javascript text/css application/xml application/x-httpd-php;
    gzip_vary on;
    proxy_buffer_size 128k;
    proxy_buffers 32 32k;
    proxy_busy_buffers_size 128k;
    open_file_cache max=100000 inactive=30s; 
    open_file_cache_valid 60s; 
    open_file_cache_min_uses 2; 
    open_file_cache_errors on;
    server {
        listen 80;
        server_name localhost;
        index index.html index.jsp;
        location / {
            proxy_pass http://app-tomcat:8080;
            proxy_redirect off;
            proxy_set_header HOST $host:$server_port;
            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 90;
            proxy_send_timeout 90;
            proxy_read_timeout 90;
            proxy_buffer_size 4k;
            proxy_buffers 4 32k;
            proxy_busy_buffers_size 64k;
            proxy_temp_file_write_size 64k;        
        }
    }
}

然后我们创建编排好的容器

docker-compose up -d

然后查看下容器状态

docker-compose ps

看到都是正常的，最后我们访问下

http://localhost
和
http://localhost:8080

发现报404的错误，这是因为tomcat容器内的webapps目录下是空的，我们进入容器内查看下

docker exec -it app-tomcat bash
ls /usr/local/tomcat/webapps/

发现这个目录下是空的，但是在webapps.dist 文件夹内找到了，我们试着将这里所有文件复制一份到webapps目录下

cp -rf /usr/local/tomcat/webapps.dist/* /usr/local/tomcat/webapps

然后再访问上面两个网址，发现都能打开tomcat的默认页面了
