虚拟机下搭建JDK+Tomcat+Nginx环境【一】——安装准备工作

虚拟机下搭建JDK+Tomcat+Nginx环境【二】——部署多tomcat

基于上两篇文章，环境基本搭建完成。这一篇记录配置Nginx，监听Tomcat端口。

打开Nginx配置文件，命令：vim /export/servers/nginx-1.12.0/conf/nginx.conf

配置监听多个应用，格式为在conf文件夹建立domains文件夹，放置各个应用的配置，nginx.conf放置基本配置。

Nginx配置有几篇文章讲的不错：

我的nginx.conf配置：

user                    nobody;
#虚拟机有几核写几核，我的虚拟机两核
worker_processes        2;
#绑定worker进程和cpu 
worker_cpu_affinity     10 01;
#指一个nginx进程打开的最多文件描述符个数，理论值是最多打开文件数（ulimit -n）与nginx进程数相除，但是nginx分配请求不那么均匀，最好和ulimit -n 保持一致
。

        #不能大于操作系统支持的最大文件句柄数

        include domains/*;

}

domain内配置（下面是test1配置，test2相似）：

upstream test1_base {
                server 127.0.0.1:8081;
}

server {
                listen                   80;
                server_name             test1.test.com;
                access_log               /export/servers/nginx-1.12.0/logs/test1/test1.test.com_access.log main;
                error_log                /export/servers/nginx-1.12.0/logs/test1/test1.test.com_error.log warn;
      location / {
        proxy_next_upstream     http_500 http_502 http_503 http_504 error timeout invalid_header;
        proxy_set_header        Host  $host;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass              http://test1_base;
        expires                 1d;
        }
        location /logs/ {
                autoindex       off;
                deny all;
        }
}

配置host，修改/etc/hosts文件

127.0.0.1 test1.test.com test2.test.com
