Tomcat Connector的三种运行模式

详情参考：
http://tomcat.apache.org/tomcat-7.0-doc/apr.html
http://www.365mini.com/page/tomcat-connector-mode.htm

操作环境：rhel6.3 x86_x64、 tomcat7.0.42

tomcat connector三种运行模式分别为：bio、nio和apr。你可以简单地理解成，性能上：bio<nio<=apr

其中bio为默认运行方式，即（server.xml）:

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

nio，只需修改protocol为：

<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="20000" redirectPort="8443" />

如果要进入apr运行模式，就稍稍麻烦些。除了修改protocol：

<Connector port="" protocol="org.apache.coyote.http11.Http11AprProtocol" connectionTimeout="" redirectPort="" />

还需要安装部分组件来构建apr运行环境（openssl一般系统默认安装），方法如下：

#install apr & tcnative
cd apr-1.5./
./configure --prefix=/tomcat/lib/apr
make
make install

cd apr-iconv-1.2./
./configure --prefix=/tomcat/lib/apr-iconv --with-apr=/tomcat/lib/apr
make
make install

cd apr-util-1.5./
./configure --prefix=/tomcat/lib/apr-util --with-apr=/tomcat/lib/apr --with-apr-iconv=/tomcat/lib/apr-iconv
make
make install

cd tomcat-native-1.1.-src/jni/native/
./configure --prefix=/tomcat/lib/apr --with-apr=/tomcat/lib/apr --with-java-home=$JAVA_HOME
make
make install

export LD_LIBRARY_PATH=/tomcat/lib/apr/lib:$LD_LIBRARY_PATH

#startup the tomcat
bin/startup.sh

#访问 http://localhost:8080/manager/status/all 查看运行模式 或者 查看启动日志
