tomcat 設置 APR TC native

 

1、tomcat各類鏈接器比較

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 、編譯打包apr tc native

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

安裝各類lib

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

二、下載 tcnative

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

rhel安裝要注意 1.2.7 目前支持的openssl版本最高爲 OpenSSL version to 1.0.2h , 若有須要用到ssl，請先自行升級openssl，不過目前rhel官方庫並無這個版本。

若是是centos 那就本身隨意搞了，呵呵。
若是是debian/ubuntu 就無視了

三、安裝編譯

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/

按照官方文檔說明，可指定各個組件的位置， 其實不寫明也能本身找到。


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

最後就會安裝到 $CATALINA_HOME/lib中。

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

下面是個人作法：

我這裏配置環境不太同樣，因爲前方有設備統一卸載SSL負載，因此這裏也不須要SSL， 所以不編譯SSL。 步驟以下：

如下是步驟

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、 推到內網下載服務器，編譯打包就完成了

省略

3、 客戶端配置
1\
從內網軟件庫下下來

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

這裏的SSLEngine改成off 由於不須要
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" />

增長鏈接設置
<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\
啓動tomcat

startup.sh

檢查tcnative是否ok

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

lsof 看一下

lsof -p PID

發現：

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

好了配置完畢

若是須要SSL 請查閱tomcat官方文檔配置， 同時tcnative編譯時按照官方文檔作法編譯便可。這裏不BB了。
