(15)Docker之用Nginx实现SpringBoot应用的负载均衡简单记录

标签:nginx配置文件 erer 构建 roo body 假设 arch param 失败 怎样用Docker部署SpringBoot应用请参考上篇文章,本文假设已经部署了两个SpringBoot应用: 访问:http://192.168.43.151:8080/user/test 输出“测试1” 访问:http://192.168.43.151:8081/user/test 输出“测试2” 下面说一下怎么安装Nginx,以及实现两个应用的负载,本文采用简单轮询。 1、安装Nginx 1)安装镜像 查找镜像 拉取镜像 说明:拉取的最新镜像。ps:之前不知道怎么误删了/var/lib/nginx下的tmp目录,导致无法拉取,重建后好了。 2)根据镜像,启动构建容器 2、准备Nginx配置文件 编写负载均衡文件upstream_test.conf 修改主配置文件nginx.conf 注意:红色字是添加或者修改的部分 3、将配置文件放到容器中 【格式】docker cp 宿主机目录 容器ID:容器目录 重新启动容器 4、测试 浏览器输入:http://192.168.43.151/user/test 不停刷新,发现轮询输出 “测试1”、“测试1”,测试 成功! 备注 如果将配置文件cp到容器中,重启容器失败,可以重新cp一个正确的覆盖或者直接重新run一个容器。 如果不想执行cp命令复制文件,可以考虑容器卷的方式。 (15)Docker之用Nginx实现SpringBoot应用的负载均衡简单记录 标签:nginx配置文件 erer 构建 roo body 假设 arch param 失败 原文地址:https://www.cnblogs.com/javasl/p/13357222.htmldocker search nginx
