Centos下Tomcat 安装 apr (Apache Portable Runtime)

摘选自:http://blog.chenlb.com/2009/01/install-apache-portable-runtime-or-tomcat-native-on-tomcat.html

apr 与 tomcat-native 提供更好的伸缩性、性能和集成到本地服务器技术。

如果没有apr技术,启动tomcat 时出现如下提示:

信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/jdk1.6.0_06/jre/lib/i386/client:/usr/java/jdk1.6.0_06/jre/lib/i386:/usr/java/jdk1.6.0_06/jre/../lib/i386:/usr/java/packages/lib/i386:/lib:/usr/lib

按照官方说明需要:

  • APR library
  • OpenSSL libraries

openssl 可以用 yum install openssl-devel,apr还是下载*.gz来安装。
apr-1.3.2.tar.gz
apr-util-1.3.2.tar.gz
两个可以在 http://apache.mirror.phpchina.com/apr/ 找到。
tomcat-native.tar.gz 可以在tomcat/bin目录下找到。

安装 apr

  1. wget http://apache.mirror.phpchina.com/apr/apr-1.3.2.tar.gz  
  2. tar zxvf apr-1.3.2.tar.gz  
  3. cd apr-1.3.2  
  4. ./configure  
  5. make
  6. make install

apr 默认安装在 /usr/local/apr

安装 apr-util

  1. wget http://apache.mirror.phpchina.com/apr/apr-util-1.3.2.tar.gz  
  2. tar zxvf apr-util-1.3.2.tar.gz  
  3. cd apr-util-1.3.2  
  4. ./configure --with-apr=/usr/local/apr  
  5. make
  6. make install

安装 tomcat-native

  1. cd /usr/local/tomcat-6.0.18/bin  
  2. tar zxvf tomcat-native.tar.gz  
  3. cd tomcat-native-1.1.14-src/jni/native  
  4. ./configure --with-apr=/usr/local/apr --with-java-home=/usr/java/jdk1.6.0_11  
  5. make
  6. make install

设置 apr 的环境变量:

  1. vi /etc/profile  
  2. # 后面添加以下内容
  3. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib  
  4. # 使profile生效,
  5. source /etc/profile 

启动 tomcat 后, 看日志:

  1. bin/startup.sh  
  2. head logs/catalina.out 

可以看到以下结果:

信息: Loaded APR based Apache Tomcat Native library 1.1.14.
2009-1-13 11:12:51 org.apache.catalina.core.AprLifecycleListener init
信息: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].

备注:请替换当前所使用的JDK版本;必须是JDK,JRE在编译tomcat-native时将不能通过!
