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；

1.nginx安装

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

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;

}
