#  #

# 一、拉取镜像及创建挂载文件 #

#拉取nginx镜像
    docker pull registry.docker-cn.com/library/nginx
    #用于挂载nginx web文件
    mkdir -p /home/nginx/www
    #用于挂载nginx配置文件
    mkdir -p /home/nginx/conf
    #用于挂载zookeeper日志文件
    mkdir -p /home/nginx/logs
    #修改image的tgs
    docker tag registry.docker-cn.com/library/nginx nginx

# 二、启动容器 #

#先启动
    docker run -p 9999:80 --name mynginx -d nginx
    #拷贝配置文件
    docker cp -a mynginx:/etc/nginx/ /home/nginx/conf
    #修改配置文件
    vi /home/nginx/conf/nginx/nginx.conf
    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;
        keepalive_timeout  65;
        upstream www_server_pools {
    		server 47.105.108.195:15672 weight=1;
    		server 47.105.108.195:15672 weight=1;
    	}
    	upstream bbs_server_pools {
    		server 47.105.108.195:15672 weight=1;
    		server 47.105.108.195:15672 weight=1;
        }
    
        include /etc/nginx/conf.d/*.conf;
    }
    
    vi /home/nginx/conf/nginx/conf.d/default.conf
    server {
        listen       80;
        server_name  localhost;
    
        location / {
            proxy_pass http://www_server_pools;
        }
    
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
    server {
        listen       80;
        server_name  localhost;
    
        location / {
            proxy_pass http://bbs_server_pools;
        }
    
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
    
    #再启动
    docker run -p 9999:80 --name mynginx -v /home/nginx/www:/www -v /home/nginx/conf/nginx:/etc/nginx -v /home/nginx/logs:/wwwlogs -d nginx
    #-p 9999:80：将容器的80端口映射到主机的9999端口
    #--name nginx：将容器命名为mynginx
    #-v /home/nginx/www:/www：将主机中当前目录下的www挂载到容器的/www
    #-v /home/nginx/conf:/etc/nginx：将主机中当前目录下的nginx.conf挂载到容的/etc/nginx/nginx.conf
    #-v /home/nginx/logs:/wwwlogs：将主机中当前目录下的logs挂载到容器的/wwwlogs

# `三、防火墙设置` #

#编辑防火墙配置文件
    vi /etc/sysconfig/iptables
    -A IN_public_allow -p tcp -m tcp --dport 9999 -m conntrack --ctstate NEW -j ACCEPT
    #重启防火墙
    systemctl restart iptables
    
    ##如果是云服务需到云端配置安全组规则

# 四、docker-compose安装 #

# 先启动一个nginx，拷贝文件到本地：docker cp -a nginx:/etc/nginx ./config/
    version: '3'
    services:
        nginx:
          image: 'nginx'
          restart: always
          container_name: myhome
          ports:
            - '9999:80'
          volumes:
            - /srv/dev-disk-by-id-ata-HITACHI_HUA723030ALA640_YHJL158A-part1/appdata/myhome/config/nginx:/etc/nginx
            - /srv/dev-disk-by-id-ata-HITACHI_HUA723030ALA640_YHJL158A-part1/appdata/myhome/html:/usr/share/nginx/html
            - /srv/dev-disk-by-id-ata-HITACHI_HUA723030ALA640_YHJL158A-part1/appdata/myhome/logs:/var/log/nginx
