7 docker容器演练

一 环境说明：

tomat mysql nginx 三个容器，如下图，目的让nginx反向代理tomcat,并且连接数据库

二 tomcat配置

里面跑了两个应用程序，一个是tomcat自带的程序端口8080，另一个是java -jar 启动的程序端口8000
demo-0.0.1-SNAPSHOT.jar 这个jar包里面填写了数据库的一些信息
启动tomcat 容器

docker run  -p 8080:8080 -d --rm --name tomcat_jdk -v /mydockerfile/tomcat/test:/usr/local/apache-tomcat-7.0.63/webapps/test -v /mydockerfile/tomcat/tomcatlogs/:/usr/local/apache-tomcat-7.0.63/logs --privileged=true hnftomcat java -jar /usr/local/apache-tomcat-7.0.63/webapps/test/demo-0.0.1-SNAPSHOT.jar

三 nginx配置

反向代理了两个应用，分别是8080和8000

1 nginx配置文件如下：

upstream tm {
  server 172.17.0.2:8000; #tomcat容器的ip,jar包的端口
}
upstream tomcat {
  server 172.17.0.2:8080; #tomat的端口
}
server {
    listen       80;
    server_name  www.tomcat.com;

    access_log  /var/log/nginx/host.access.log  main;
    location / {
            proxy_pass http://tomcat;
            proxy_set_header Host  $host;
            proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP  $remote_addr;
        }

    
}

server {
    listen       80;
    server_name  www.hu.com;

    access_log  /var/log/nginx/host.access.log  main;

    location /pc/ {
        
        alias   /usr/share/nginx/html/;
        index  index.html index.htm;
    }
    location / {
            proxy_pass http://tm;
            proxy_set_header Host  $host;
            proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP  $remote_addr;
        }
    location /tomcat/ {
            proxy_pass http://tomcat;
            proxy_set_header Host  $host;
            proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP  $remote_addr;
        }



    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }



}

2 启动nginx容器

docker run -p 80:80 --rm -v /mydockerfile/nginx/conf:/etc/nginx/conf.d/ -v /mydockerfile/nginx/logs/:/var/log/nginx -v /mydockerfile/nginx/html/:/usr/share/nginx/html -d nginx

浏览器访问 ，访问之前，绑定两个域名
http://www.hu.com/pc/这里面的数据是从数据库读取过来的

下面是代理的tomcat,www.tomcat.com

四 启动mysql容器

 docker run -p 3306:3306 --name mysql --rm -v /mydockerfile/mysql/conf:/etc/mysql/conf.d -v /mydockerfile/mysql/logs:/logs -v /mydockerfile/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6
