Tomcat安装APR

Ttomcat可以使用Apache的apr 【Apache portable Run-time libraries，Apache可移植运行库】，这样可以加速IO的访问和使用Openssl

安装步骤：

所需软件包：

-- apr.tar.gz

-- apr-util.tar.gz

-- tomcat-native.tar.gz   //tomcat自带

1. 安装apr.tar.gz

# tar zxvf apr.tar.gz

# cd apr

# ./configure

# make

# make install

//apr被安装在/usr/local/apr下

2. 安装apr-util.tar.gz

# tar zxvf apr-util.tar.gz

# cd apr-util

# ./configure --with-apr=/usr/local/apr

// --with-apr=/usr/local/apr 指定APR安装路径

# make

# make install

3. 安装tomcat-native.tar.gz

# cd /usr/local/tomcat/bin

# tar zxvf tomcat-native.tar.gz

# cd tomcat-native-1.1.10-src/jni/native

# ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/jdk

4. 添加环境变量

# vi /etc/profile

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

5.修改conf/server.xml

<Connector protocol="HTTP/1.1"/>

 改为：

<Connector protocol="org.apache.coyote.http11.Http11AprProtocol"/>

5. 重启tomcat查看结果

# vi /usr/local/tomcat/logs/catalina.out

原来为

org.apache.coyote.http11.Http11Protocol start

INFO: Starting Coyote HTTP/1.1 on http-8080

现在为

Apr 1, 2011 3:33:53 PM org.apache.coyote.http11.Http11AprProtocol start

INFO: Starting Coyote HTTP/1.1 on http-10004

Apr 1, 2011 3:33:53 PM org.apache.coyote.ajp.AjpAprProtocol start

INFO: Starting Coyote AJP/1.3 on ajp-10005

Apr 1, 2011 3:33:53 PM org.apache.catalina.startup.Catalina start
