对ARP支持,需要安装以下库:
- APR library
- JNI wrappers for APR used by Tomcat (libtcnative)
- OpenSSL libraries
其中JNI wrappers(libtcnative)安装依赖另外两项,以及Java headers.(It depends on APR, OpenSSL, and the Java headers),也就是:
- APR 1.2+ development headers (libapr1-dev package)
- OpenSSL 0.9.7+ development headers (libssl-dev package)
- JNI headers from Java compatible JDK 1.4+
- GNU development environment (gcc, make)
首先安装APR和OpenSSL:
$ sudo apt-get install libapr1-dev libssl-dev
但是,这样安装APR总是找不着lib,还是手动安装一下:
1. 下载:
wget http://apache.fayea.com/apache-mirror//apr/apr-1.5.2.tar.gz
wget http://apache.fayea.com/apache-mirror//apr/apr-util-1.5.4.tar.gz
或者去网页下载最新版本:
http://apr.apache.org/download.cgi
2. 解压:
tar -zxvf apr-1.5..tar.gz
tar -zxvf aor-util-1.5..tar.gz
3. 安装(使用root账号,或者每条命令前加sudo):
cd apr-1.5.
./configure --prefix=/usr/local/apr
make
make install
cd ..
cd apr-util-1.5.
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make
make insatll
apr默认安装到/usr/local/apr,所以不加--prefix也可以。apt-util必须加--with-apr,否则找不到apr。
最后安装JNI wrappers,The wrapper library sources are located in the Tomcat binary bundle, in the bin/tomcat-native.tar.gz
archive.
cd /xxxx/apache-tomcat-xxx/bin
tar -zxvf tomcat-native.tar.gz
cd tomcat-native-xxx-src/jni/native
./configure --with-apr=/usr/local/apr --with-java-home=/usr/lib/jvm/jdk1..0_91
make
make install
最后的最后,需要配置环境变量:
vi /etc/profile export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
重启电脑生效。
启动tomcat,有以下信息,说明APR配置生效:
INFO: Loaded APR based Apache Tomcat Native library 1.1. using APR version 1.5..
...... INFO: Initializing ProtocolHandler ["http-apr-8080"]
...... INFO: Initializing ProtocolHandler ["ajp-apr-8009"]
