WEB服务的下载限速（一)(Apache与Tomcat整合)
阴 19°公司要发布一个apk应用，但不能让用户全速下载。Tomcat本身不能对速度限制。
思路
1、整合Apache和Tomcat
2、Apache加载Bandwidth模块
一、准备所需软件
1、httpd-2.4.7.tar.gz http://mirror.esocc.com/apache/httpd/
2、jakarta-tomcat-connectors-1.2.15-src.tar.gz http://archive.apache.org/dist/jakarta/tomcat-connectors/jk/source/jk-1.2.15/
3、tomcat方面因为已经安装了，我这边就不需要了
二、安装apache
# tar xzvf httpd-2.4.7.tar.gz
# cd httpd-2.4.7
# ./configure --prefix=/usr/local/apache --enable-so
# make
# make install
三、编译生成mod_jk
# tar xzvf jakarta-tomcat-connectors-1.2.15-src.tar.gz
# cd jakarta-tomcat-connectors-1.2.15-src/jk/native
# ./configure --with-apxs=/usr/local/apache/bin/apxs
# make
# cp ./apache-2.0/mod_jk.so /usr/local/apache/modules/
四、连接apache和tomcat
1、
cd /usr/local/apache/conf/
vim mod_jk.conf
添加
# 指出mod_jk模块工作所需要的工作文件workers.properties的位置
JkWorkersFile /usr/local/apache/conf/workers.properties
# Where to put jk logs
JkLogFile /usr/local/apache/logs/mod_jk.log
# Set the jk log level
JkLogLevel info
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"
# 将所有servlet 和jsp请求通过ajp13的协议送给Tomcat，让Tomcat来处理
JkMount /servlet/* worker1
JkMount /*.jsp worker1
2、
vi workers.properties
添加
# Defining a worker named worker1 and of type ajp13
worker.list=worker1
# Set properties for worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009
worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300
3、修改apache主配置文件
vim /usr/loacl/apache/conf/httpd.conf
添加index.jsp支持
<IfModule dir_module>
DirectoryIndex index.html index.jsp
</IfModule>
添加别名(根据各自需要了)
我的tomcat放在/usr/apache-tomcat-7.0.47
Alias /test2 "/usr/apache-tomcat-7.0.47/webapps/test"
<Directory "/usr/apache-tomcat-7.0.47/webapps/test">
AllowOverride None
Options Indexes MultiViews
Order allow,deny
Allow from all
</Directory>
加载apache-tomcat连接模块
找到LoadModule的地方添加一段
LoadModule jk_module modules/mod_jk.so
同样在nclude conf/extra/httpd-ssl.conf下面添加一段
Include /usr/local/apache2/conf/mod_jk.conf
4、配置tomcat
vim /usr/apache-tomcat-7.0.47/conf/server.xml
添加或修改
<Context path="/test2" docBase="/usr/apache-tomcat-7.0.47/webapps/test" reloadable="false" crossContext="true" />
标红的地址必须和apache上别名下面的标红地址一致
5、编写一个jsp页面
vim /usr/apache-tomcat-7.0.47/webapps/test/index.jsp
<HTML>
<HEAD>
<TITLE>JSP测试页面---HelloWorld!</TITLE>
</HEAD>
<BODY>
<%
out.println("<h1>Hello World!<br>世界，你好！</h1>");
%>
</BODY>
</HTML>
6、重启apache和tomcat
/usr/local/apache/bin/httpd -k restart
/usr/apache-tomcat-7.0.47/bin/shutdown.sh
/usr/apache-tomcat-7.0.47/bin/start.sh
7、测试一下
成功。。。
