一、Resin简介
Resin官网地址：http://caucho.com/
Resin源码包下载地址：http://caucho.com/products/resin/download
Resin是CAUCHO公司的产品，是一个非常流行的支持servlets和jsp的引擎，速度非常快。
Resin本身包含了一个支持HTTP/1.1的WEB服务器。虽然它可以显示动态内容，但是它显示静态内容的能力也非常强，速度直逼APACHESERVER。许多站点都是使用该WEB服务器构建的
Resin也可以和许多其他的WEB服务器一起工作，比如Apache server和IIS等。Resin支持Servlets 2.3标准和JSP 1.2标准。熟悉ASP和PHP的用户可以发现用Resin来进行JSP编程是件很容易的事情
Resin支持负载平衡（Load balancing），可以增加WEB站点的可靠性。方法是增加服务器的数量。比如一台SERVER的错误率是1%的话，那么支持负载平衡的两个Resin服务器就可以使错误率降到0.01%
版本区别
resin 普通版本和pro版本主要区别是 pro支持缓存和负载均衡。pro因为有强大的cache功能，独立作为web服务器处理静态页面性能都可以和apache有一比。但普通版本独立作为web服务器性能就要差一些。当然可以使用apache+resin的方案借助apache的缓存功能提高性能。 但负载均衡就是普通版不能比的了。

3、启动Resin服务

#第一种方法启动
[root@Resin ~]
# /usr/local/resion/bin/resin.sh start
Resin
/4
.0.40 launching watchdog at 127.0.0.1:6600
Resin
/4
.0.40 started -server
'app-0'
with watchdog at 127.0.0.1:6600
第二种方法启动
[root@Resin ~]
# service resin start
|
4、验证Resin

[root@Resin ~]
# netstat -tnlp |grep java
tcp 0 0 127.0.0.1:6800 0.0.0.0:* LISTEN 4338
/java
tcp 0 0 127.0.0.1:6600 0.0.0.0:* LISTEN 4292
/java
tcp 0 0 :::8080 :::* LISTEN 4338
/java
|
5、浏览器访问Resin
5.2 点击【/resin-admin】进入登陆、注册页面；如下图所示
5.3 由于首次登陆Resin还没有用户，所以先注册一个管理员账号；如下图所示
5.4 点击【Create Configuration File】；如若用户创建成功，提示如下图所示
5.5 注册用户创建成功后会在/usr/local/resion/conf目录下生成一个admin-users.xml.generated的模板文件，这个模板不能直接使用，我们需要将其改成为admin-users.xml文件
|
1
2
|
[root@Resin ~]# cd /usr/local/resion/conf/
[root@Resin conf]# cp admin-users.xml.generated admin-users.xml
|
注释：如果部署到无GUI界面的系统上如：CentOS Solaris Ubuntu-Server等，无法通过浏览器访问本地resin-admin，则需要修改resin.properties文件爱你，开启远程访问权限，然后再次登录
|
1
|
[root@Resin conf]# vim resin.properties
|
5.6 首次登陆后的界面如下：
四、简单的Resin部署web测试环境
1、拷贝自已的项目到Resin的webapps目录下

-->
<web-app
id
=

root-directory=
"webapps/ROOT"
/>
<web-app
id
=
"/api"
root-directory=
"webapps/api"

<
/host

|
3、测试
五、Resin4基于目录和域名的部署
1、同一个域名下多个子app，根据url层级来指向
http://www.allentuns.com/api2
2、多个域名对应指定的host，根据域名来指定
