安装Tomcat的Apr

安装Tomcat的Apr，提升性能

发现 Tomcat 可以用 Apache Portable Runtime 来提供更强性能，提升Web静态页面的处理能力，不再需要专门的Web Server来处理静态页面了。
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 -y openssl-devel

apr还是下载*.gz来安装。

(0)安装gcc

yum install gcc -y

(1)安装apr

cd /data
wget http://mirrors.cnnic.cn/apache//apr/apr-1.5.2.tar.gz
tar zxf apr-1.5.2.tar.gz
cd apr-1.5.2
./configure --prefix=/usr/local/apr
make && make install

(2)安装apr-iconv

cd /data
wget http://mirrors.cnnic.cn/apache//apr/apr-iconv-1.2.1.tar.gz
tar zxf apr-iconv-1.2.1.tar.gz
cd apr-iconv-1.2.1
./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr
make && make install

(3)安装apr-util

cd /data
wget http://mirrors.cnnic.cn/apache//apr/apr-util-1.5.4.tar.gz
tar zxf apr-util-1.5.4.tar.gz
cd apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr --with-apr-iconv=/usr/local/apr-iconv/bin/apriconv
make && make install

(4)安装tomcat-native

cd /data/tomcat/bin/
tar zxf tomcat-native.tar.gz
cd tomcat-native-1.1.33-src
cd jni/native/
./configure --with-apr=/usr/local/apr
make && make install

(5)设置 apr 的环境变量

cd /data/tomcat/bin
vi catalina.sh

添加下面的代码

#!/bin/sh

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
export LD_LIBRARY_PATH

(6)设置 tomcat 的连接器 Http11AprProtocol

cd /data/tomcat/conf
vim server.xml

修改Connector的protocol属性值

<Connector port="80"
protocol="org.apache.coyote.http11.Http11AprProtocol"
