centos6.2下，Tomcat运行模式apr安装过程，如下：
一、安装apr
[root@vmT227-m5 /]# cd /usr/local/ [root@vmT227-m5 local]# tar zxvf apr-1.4.2.tar.gz
[root@vmT227-m5 local]# ./configure --prefix=/usr/local/ap
如果报错误：rm: cannot remove `libtoolT': No such file or directory
解决方法：
[root@vmT227-m5 apr-1.4.2]# vi configure 将 RM='$RM' 改成： RM='$RM -f'
[root@vmT227-m5 apr-1.4.2]# make && make install
二、安装apr-iconv
[root@vmT227-m5 local]# tar -zxvf apr-iconv-1.2.1.tar.gz [root@vmT227-m5 local]# cd apr-iconv-1.2.1 [root@vmT227-m5 local]# ./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr [root@vmT227-m5 local]# make && make install
三、安装apr-util
[root@vmT227-m5 local]# tar zxvf apr-util-1.3.10.tar.gz [root@vmT227-m5 local]# cd apr-util-1.3.10 [root@vmT227-m5 local]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr --with-apr-iconv=/usr/local/apr-iconv/bin/apriconv [root@vmT227-m5 local]# make && make install
四、安装tomcat-native
[root@vmT227-m5 local] cd /usr/local/tomcat-jiaoshiduan-app/bin/ #tomcat安装路径 [root@vmT227-m5 bin]# tar zxvf tomcat-native-1.1.33-src.tar.gz [root@vmT227-m5 bin]# cd tomcat-native-1.1.33-src/jni/native [root@vmT227-m5 bin]# ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/jdk1.7.0_75 [root@vmT227-m5 bin]# make && make install
五、配置tomcat apr模式
[root@vmT227-m5 local] vim /etc/profile #apr export LD_LIBRARY_PATH=/usr/local/apr/lib [root@vmT227-m5 local] source /etc/profile
六、修改server.xml
将 <Connector port="28080" protocol="HTTP/1.1”中的protocol修改成org.apache.coyote.http11.Http11AprProtocol，然后重启Tomcat，看到以下内容，表示apr模式安装成功
org.apache.catalina.core.AprLifecycleListener init INFO: Loaded APR based Apache Tomcat Native library 1.1.20. INFO: Starting ProtocolHandler ["http-apr-8080"] INFO: Starting ProtocolHandler ["ajp-apr-8019"]
