nginx配置分发tomcat服务

##搭建环境：

1. ubuntu 16.04 LTS

2. apache tomcat 7

3. java 7

4. nginx/1.10.0 (ubuntu)

##搭建过程：

注：本人在这里介绍自己安装的两种方式，一种使用官方源码包进行安装，另外一种使用ubuntu软件源进行安装，但推荐大家使用源码包进行安装，源码安装更易后期配置。

使用官方源码包进行安装

1. 资源准备

   • pcre 源码包 （为了rewrite）

   • zlib 源码包 （为了压缩gzip）

   • ssl（openssl）源码包 （如果已安装可直接使用）

   • nginx源码包

   • gcc等系统编译工具（请自行准备，一般linux系统都会自带）

2. 开始安装

   1. 分别解压三个压缩包

      tar -zxvf pcre.tar.gz

      tar -zxvf nginx.tar.gz

      tar -xvf zlib.tar.gz(注：官方源码包因为不是gzip压缩，所以不能使用 -z)

   2. 使用第一步解压的源码包路径，cd /usr/local/src/nginx-1.10.2目录，在这之前我已使用.configure，make,make install进行安装之前的pcre和zlib，输入以下指令，指定安装路径到/usr/local/nginx（路径可以自定义）

      sudo ./configure --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.38 --with-zlib=/usr/local/src/zlib-1.2.8 --with-openssl=/usr/local/src/openssl-1.1.0c

      make

      make install

   3. 修改nginx.config

      vim /usr/local/nginx/nginx.conf

      在http节点的server{}标签内部末尾添加：

      ”` location ^~ /service/ { #对url中包含/service/进行拦截分发

           proxy_pass   http://127.0.0.1:8080/; #代理服务地址
      
      
          	proxy_redirect  off;
      
      
          	proxy_set_header  X-Real-IP $remote_addr;
      
      
          	proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
      

      }“`

   4. 启动，停止服务 sudo /usr/local/nginx/nginx

      sudo /usr/local/nginx/nginx -s stop

   5. 启动tomcat项目 最后访问ip+/service/即可通过nginx访问到你的tomcat服务

使用ubuntu软件源进行安装

1. sudo apt install nginx

2. vim /etc/nginx/sites-enabled/default

   在server{}标签内末尾出增加：

   ”` location ^~ /service/ {#对url中包含/service/进行拦截分发

       proxy_pass   http://127.0.0.1:8080/;#代理服务地址
   
   
       proxy_redirect  off;
   
   
       proxy_set_header  X-Real-IP $remote_addr;
   
   
       proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
   
   
   }```
   

   default完整配置如下：

3. service nginx restart

   最后访问ip+/service/即可通过nginx访问到你的tomcat服务,关于更多动静分离配置以及负载均衡，可参阅如上提供的官方文档，此博客未完待续，后期不定时更新。

   注：如果操作期间出现错误 可使用

   tail 或 cat /var/log/nginx/error.log

   查看错误日志再进行处理
