Nginx+Tomcat搭建

Nginx简介

Nginx ("engine x") 是一个高性能的 HTTP 和 反向代理 服务器，也是一个 IMAP/POP3/SMTP 代理服务器 。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的Rambler.ru 站点开发的，它已经在该站点运行超过四年多了。Igor 将源代码以类BSD许可证的形式发布。自Nginx 发布四年来，Nginx 已经因为它的稳定性、丰富的功能集、 示例配置文件和低系统资源的消耗而闻名了。目前国内各大门户网站已经部署了Nginx，如新浪、网易、腾讯等；国内几个重要的视频分享网站也部署了Nginx，如六房间、酷6等。 新近发现Nginx 技术在国内日趋火热，越来越多的网站开始部署Nginx。

前置准备

可能要用到的包、工具

1.yum –y install lrzsz   //上传下载工具，高大上的工具，再次鄙视那些用ftp工具的

2.yum –y install gcc gcc-c++  //两个包gcc和gcc-c++  为了pcre的编译

3.yum –y install openssl*   //ssl的支持

4.yum install pcre*

5.yum install zlib 

6.yum install zlib-devel

7. yum install wget

 

要是编译报错看错误提示，有的可能是少包的支持，没啥yum啥

 

关闭防火墙

首先把防火墙关闭：service iptables stop

再设置为永久关闭：chkconfig iptables off

一定要关，不然本地可能访问不了虚拟机上的apache

 

JDK安装

Nginx安装

Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个，下面是把 Nginx 安装到 /usr/local/nginx 目录下的详细步骤：

 

cd/usr/local/

下载nginx安装包

wget http://nginx.org/download/nginx-1.9.3.tar.gz

创建安装目录

 mkdir /usr/local/nginx

解压nginx

tar -zxvf  nginx-1.9.3.tar.gz

进入目录

cd  nginx-1.9.3  

配置。通常将软件安装在/usr/local/目录下。

./configure --prefix=/usr/local/nginx --with-pcre=/usr/local/pcre-8.21--with-zlib=/usr/local/zlib-1.2.8 --with-http_stub_status_module--with-openssl=/usr/local/openssl-1.0.1c --with-http_ssl_module

编译

make

安装

make  install

 

--with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源码路径。

--with-zlib=/usr/src/zlib-1.2.8 指的是zlib-1.2.8 的源码路径。

--with-openssl=/usr/local/openssl-1.0.1c指的是openssl-1.0.1c的源码路径。

检查是否安装成功

# cd /usr/local/nginx/sbin

# ./nginx -t

结果显示：

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

启动

确保系统的 80 端口没被其他程序占用，

/usr/local/nginx/sbin/nginx

 

检查是否启动成功：

netstat-ano|grep 80 有结果输入说明启动成功

IE输入IP：端口，出现如下表示安装nginx成功

修改配置文件

cd/usr/local/nginx/conf

vinginx.conf

10.Nginx负载均衡的相关配置代码如下：

upstream mytomcats { 

      server 192.168.12.132:8080; 

      server 192.168.12.133:8080; 

      server 192.168.12.134:8080; 

} 

 

server{ 

      listen 80; 

      server_name www.ixdba.net; 

location~* \.(jpg|gif|png|swf|flv|wma|wmv|asf|mp3|mmf|zip|rar)$ { 

      root /web/www/html/; 

}  

 

location /{ 

    root  html;

          index index.html index.htm;

          proxy_pass http://mytomcats; 

          proxy_redirect off; 

          proxy_set_header Host $host; 

          proxy_set_header X-Real-IP$remote_addr; 

          proxy_set_header X-Forwarded-For$proxy_add_x_forwarded_for; 

          client_max_body_size 10m; 

          client_body_buffer_size 128k; 

          proxy_connect_timeout 90; 

          proxy_send_timeout 90; 

          proxy_read_timeout 90; 

          proxy_buffer_size 4k; 

          proxy_buffers 4 32k; 

          proxy_busy_buffers_size 64k; 

          proxy_temp_file_write_size 64k;

}

}

测试负载

在两个tomcat下加入工程test

mkdir /usr/local/tomcat1/webapps/test

mkdir /usr/local/tomcat2/webapps/test

在两个test工程下分别创建test.jsp,内容如下

<%@ pagecontentType="text/html;charset=UTF-8"%>

<html>

<head>

<title> Tomcat_test1</title>

</head>

<body>

<font color = "red" size ="20" >

<% out.print( "test111" );%>

</font>

</body>

</html>

 

<%@ pagecontentType="text/html;charset=UTF-8"%>

<html>

<head>

<title> Tomcat_test2</title>

</head>

<body>

<font color = "red" size ="20" >

<% out.print( "test222" );%>

</font>

</body>

</html>

 

启动tomcat+nginx

启动nginx：/usr/local/nginx/sbin/nginx

启动tomcat：

/usr/local/tomcat1/bin/startup.sh

/usr/local/tomcat2/bin/startup.sh

 

查看进程

在两个IE中输入ip：nginx端口/工程/jsp页面，最好是不同浏览器，出现如下表示搭建成功
