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-1.5.1.tar.gz
apr-util-1.5.4.tar.gz
两个可以在 https://apr.apache.org/download.cgi找到。
tomcat-native.tar.gz 也可以在tomcat/bin目录下找到。

 

 


 

安装 apr

1 wget http://www.interior-dsgn.com/apache//apr/apr-1.5.1.tar.gz   
2 tar zxvf apr-1.5.1.tar.gz   
3 cd apr-1.5.1   
4 ./configure   
5 make  
6 make install

 

 

apr 默认安装在 /usr/local/apr

 


安装 apr-util

wget http://www.interior-dsgn.com/apache//apr/apr-util-1.5.4.tar.gz   
tar zxvf apr-util-1.5.4.tar.gz   
cd apr-util-1.5.4   
./configure --with-apr=/usr/local/apr   
make  
make install 

 


 

安装 tomcat-native

http://archive.apache.org/dist/tomcat/tomcat-connectors/native/1.1.32/source/tomcat-native-1.1.32-src.tar.gz
tar zxvf tomcat-native-1.1.32-src.tar.gz   
cd tomcat-native-1.1.32-src/jni/native/   
./configure --with-apr=/usr/local/apr --with-java-home=/usr/java/jdk1.7.0_71    (此处JAVA_HOME不知道,可echo $JAVA_HOME)
make;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

 

 

安装完成后

启动类似提示错误:INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/lib/jvm/java-6-sun-1.6.0.20/jre/lib/amd64/server:/usr/lib/jvm/java-6-sun-1.6.0.20/jre/lib/amd64:/usr/lib/jvm/java-6-sun-1.6.0.20/jre/../lib/amd64:/usr/lib64/xulrunner-addons:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

其实可以忽略这个错误参考(http://stackoverflow.com/questions/2231163/what-tomcat-native-library-should-i-be-using-in-production)

但是可以修改 tomcat 的启动 shell (startup.sh),在该文件中加入启动参数:
 CATALINA_OPTS="$CATALINA_OPTS -Djava.library.path=/usr/local/apr/lib" 。
