nginx的反向代理实例1

0. 实现效果

通过本地浏览器输入域名，可以实现通过nginx反向代理的操作，跳转到linux服务器的tomcat主页面的效果。

1. 准备工作

• 配置java环境
• 安装tomcat，并测试是否可以正常访问
• 配置安装nginx

2. 具体配置

2.1 在windows系统的host文件中进行域名和ip地址的对应关系配置

• 进入目录，打开hosts文件

C:\Windows\System32\drivers\etc\hosts

• 在hosts文件中添加映射规则，此时可以通过该域名访问到指定ip的地址

# ip 域名
62.234.149.220 www.test.com

2.2 修改nginx的配置文件，修改访问nginx的ip地址以及转发的url路径

• 进入conf目录

cd /usr/local/nginx/conf

• 修改配置文件 nginx.conf
  • 修改server中的server_name，改为服务器的ip地址
  • 在server中的location中添加proxy_pass属性，用于定义转发的url路径

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

2.3 测试

• 启动nginx

cd /usr/local/nginx/sbin
./nginx

• 在本地浏览器测试，输入 www.test.com 便可成功访问到tomcat的主页面
