Nginx+tomcat+ssl免费证书配置

0.说明

本文说描述的方式是用nginx的443重定向到tomcat的8443，nginx的80端口重定到tomcat的8080；

乱入：个人标记：caicongyang

1.nginx安装

可以参考我前面的文章： Linux tar包安装Nginx  ;http://blog.csdn.net/caicongyang/article/details/46388845

不过这篇文章中，我们编译的时候没有带ssl模块，因此需要重新编译安装

需要在安装时带上ssl模块的选项 

完成命令如下：

#./configure --with-http_ssl_module 

当然你可以用以下命令查看所有的编译选项

#./configure --help

2.nginx生成免费证书

# cd /opt/nginx/sslkey/
# openssl genrsa -des3 -out server.key 1024
# openssl req -new -key server.key -out server.csr
# cp server.key server.key.org
# openssl rsa -in server.key.org -out server.key
# openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

3.tomcat配置

server.xml

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" keystoreFile="${user.home}/.
keystore" keystorePass="123456"/>

我的tomcat证书是重新在生成的：（当前用户路径下）

#keytool -v -genkey -alias tomcat -keyalg RSA -keystore .keystore  -validity 36500

当然你也可以指定目录

#keytool -v -genkey -alias tomcat -keyalg RSA -keystore /opt/tomcat/sslkey/server.keystore  -validity 36500

当然你也可以在项目的web.xml中配置某个重要模块强制使用https,其他的模块正常走http

web.xml

 <security-constraint> 
           <web-resource-collection> 
                <web-resource-name>services</web-resource-name> 
                <url-pattern>/login/*</url-pattern> 
                </web-resource-collection> 
                <user-data-constraint> 
                       <transport-guarantee>CONFIDENTIAL</transport-guarantee> 
                </user-data-constraint> 
  </security-constraint> 

以上配置规定路径带login的全部走https

4.nginx配置

#user  nobody;
worker_processes  1;

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

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    server {
       listen       443;
       server_name  localhost;
