linux下 nginx + tomcat 服务器集群 (2）

来源：互联网发布：wineskin for mac 编辑：程序博客网时间：2024/05/01 18:15

在上一节中我们熟悉了linux环境，并成功搭建了nginx服务器和两个tomcat服务器，现在我们需要将他们连接起来。

注意，我们是将tomcat连接到nginx的service虚拟目录，这样nginx即可以做tomcat的负载均衡，同时还兼顾静态页面、图片等处理。

为了简化配置，我们在上一节中，将tomcat的ROOT服务也配置到了相同的目录。

整个系统的编码配置为：utf-8

配置nginx，增加upstream，作为tomcat均衡负载器

vi /usr/local/nginx/conf

错误说明：

403 ：需设置正确的用户名 / 密码。

proxypass 路径设置，如果加后缀： http://localhost/ ，则转发后的路径为： http://localhost:8080/

如果不添加后缀：http://localhost ，则转发后的路径为：http://localhost:8080/service/
