基于Docker部署Tomcat集群、 Nginx负载均衡的问题小结

详细介绍

写在前面

看完Dokcer相关的书籍，正好有个项目要这样搞，所以自己练习一下。

当作一百世一样。这里的道理很明白:我思故我在,既然我存在,就不能装作不存在。无论如何,我要为自己负起责任。——王小波《三十而立》

结构图：

这里仅作为一种学习，一般这种负载的话，Nginx是放到主机侧的， JavaWeb(Tomcat)应用放到容器里。

效果

新建文件夹。

D=uag;mkdir $D;cd $D;mkdir uag_nginx uag_tomcat8;
 ls
 uag_nginx  uag_tomcat8

一，Ngixn 镜像制作

cd uag_nginx/
# 用于存放配置文件
mkdir nginx
vim Dockerfile

Dockerfile 文件内容

FROM nginx
LABEL maintainer="uag"
ENV REFRESHED_AT 2021-08-27

EXPOSE 8099

构建nginx配置文件内容

这个的配置文件，在容器运行的时候通过 -v参数与容器内部共享。方便后期参数更改

cd ./nginx
vim nginx.conf

nginx.conf 配置文件内容

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;
daemon off;

events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  "$upstream_addr - $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;

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

    server {
        listen          8099;
        server_name     localhost;

        root            /var/www/html/;
        index           index.html index.htm;

        access_log      /var/log/nginx/default_access.log main;
        error_log       /var/log/nginx/default_error.log;

        
        location / {
                proxy_pass http://backend;
        }

        location ~ .* {
                        proxy_pass http://backend;
                        proxy_set_header Host $http_host;
                        proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                }

        

}
    # 这里配置负载 
    upstream backend {
    server 172.23.231.190:8069;
    server 172.23.231.190:8079;
    server 172.23.231.190:8089;
}
}

配置负载:172.23.231.190为宿主机IP,8069,8079,8089为对应的Java Web 暴露的应用端口。

 # 这里配置负载 
    upstream backend {
    server 172.23.231.190:8069;
    server 172.23.231.190:8079;
    server 172.23.231.190:8089;
}

构建Nginx镜像

docker build -t uag/uag_nginx .

二，java Web(Tomcat)应用镜像构建

cd uag_tomcat8/

vim Dockerfile

Dockerfile 文件内容

FROM dordoka/tomcat
MAINTAINER LIRUILONG

COPY UAWeb.war   /opt/tomcat/webapps/UAWeb.war

EXPOSE 8080

ENTRYPOINT [ "/opt/tomcat/bin/catalina.sh", "run" ]

上传对应的War包

ls
Dockerfile  UAWeb.war

构建镜像

docker build -t uag/uag_tomcat .

三，运行容器 Nginx镜像

docker run -d -p 8099:8099 --name uag_nginx  -v $PWD/nginx/nginx.conf:/etc/nginx/nginx.conf   uag/uag_nginx nginx

java Web(Tomcat)镜像

docker run -it -d -p 8089:8080 --name uag_app_1  uag/uag_tomcat
 docker run -it -d -p 8079:8080 --name uag_app_2  uag/uag_tomcat
 docker run -it -d -p 8069:8080 --name uag_app_3  uag/uag_tomcat

构建好镜像上传仓库：

嗯，需要注册一个Docker Hub账号，然后登录，需要镜像前面加 账户名/
