tomcat 设置 APR TC native

 

1、tomcat各类链接器比较

Java Blocking Connector   Java Non Blocking Connector       APR/native Connector
                                 BIO                         NIO                       APR
    Classname              Http11Protocol             Http11NioProtocol         Http11AprProtocol
    Tomcat Version           3.x onwards                 6.x onwards              5.5.x onwards
    Support Polling              NO                          YES                       YES
    Polling Size                 N/A                   maxConnections             maxConnections
    Read Request Headers      Blocking                  Non Blocking                 Blocking
    Read Request Body         Blocking                    Blocking                   Blocking
    Write Response            Blocking                    Blocking                   Blocking
    Wait for next Request     Blocking                  Non Blocking               Non Blocking
    SSL Support               Java SSL                    Java SSL                   OpenSSL
    SSL Handshake             Blocking                  Non blocking                 Blocking
    Max Connections        maxConnections              maxConnections             maxConnection

 

二 、编译打包apr tc native

一、须要的lib
APR library
OpenSSL libraries
Java SE Development Kit (JDK)

安装各类lib

apt-get install libapr1.0-dev libssl-dev #debian
或
yum install apr-devel openssl-devel  #rhel

二、下载 tcnative

wget http://mirrors.noc.im/apache/tomcat/tomcat-connectors/native/1.2.7/source/tomcat-native-1.2.7-src.tar.gz

rhel安装要注意 1.2.7 目前支持的openssl版本最高为 OpenSSL version to 1.0.2h , 若有须要用到ssl，请先自行升级openssl，不过目前rhel官方库并无这个版本。

若是是centos 那就本身随意搞了，呵呵。
若是是debian/ubuntu 就无视了

三、安装编译

下面是官方作法：

./configure --help

./configure --with-apr=$HOME/APR \
            --with-java-home=$JAVA_HOME \
            --with-ssl=$HOME/OPENSSL \
            --prefix=$CATALINA_HOME

$HOME/APR is something like /usr/bin/apr-1-config or the path where apr is installed.
$JAVA_HOME is something /home/jfclere/JAVA/jdk1.5.0_09 path to a JDK installation. Any JDK should work but it is advisable to use the same JVM version the JVM you use with Tomcat.
$HOME/OPENSSL is the path where OpenSSL is installed.
$CATALINA_HOME is the path where the produced libraries will be installed. Something like $HOME/apache-tomcat-6.0.16/

按照官方文档说明，可指定各个组件的位置， 其实不写明也能本身找到。


如：
./configure --with-apr=/usr/bin/apr-1-config \
            --with-java-home=/home/jfclere/JAVA/jdk1.5.0_09/ \
            --with-ssl=yes \
            --prefix=$CATALINA_HOME

make && make install

最后就会安装到 $CATALINA_HOME/lib中。

=======================================================================

下面是个人作法：

我这里配置环境不太同样，因为前方有设备统一卸载SSL负载，因此这里也不须要SSL， 所以不编译SSL。 步骤以下：

如下是步骤

tar -xvf tomcat-native-1.2.7-src.tar.gz 
cd tomcat-native-1.2.7-src/native/
 ./configure --disable-openssl  --prefix=/tmp/tcnative
make
make install
cd /tmp/tcnative
tar -czvf tcnative1.2.7_nossl.tgz lib/lib*

四、 推到内网下载服务器，编译打包就完成了

省略

3、 客户端配置
1\
从内网软件库下下来

cd /home/tomcat
wget http://web01/tomcat/tcnative1.2.7_nossl.tgz
tar -xvf tcnative1.2.7_nossl.tgz && rm -f tcnative1.2.7_nossl.tgz

2\
在setenv.sh 加入

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

3\
在 conf/server.xml 找到

这里的SSLEngine改成off 由于不须要
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" />

增长链接设置
<Service name="Catalina">

    <Connector port="28080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="28443" />

  <Connector port="28443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="200" SSLEnabled="false" />

4\
启动tomcat

startup.sh

检查tcnative是否ok

grep APR catalina.out
发现
INFO: Loaded APR based Apache Tomcat Native library 1.2.7 using APR version 1.4.8.

lsof 看一下

lsof -p PID

发现：

java    28799 app02  mem       REG              253,4    763798 50359083 /home/tomcat/lib/libtcnative-1.so.0.2.7

好了配置完毕

若是须要SSL 请查阅tomcat官方文档配置， 同时tcnative编译时按照官方文档作法编译便可。这里不BB了。
