tomcat中apr的配置
安装APR
安装libssl-dev:(如果没有安装会出现错误如：fatal error: openssl/opensslv.h: No such file or directory。都是没有安装libssl-dev～
libssl-dev包含libraries, header files and manpages，他是openssl的一部分，而openssl对ssl进行了实现～)
如果没做这一步，那么在最后make的时候会出现错误：
/apache-tomcat-7.0.54/bin/tomcat-native-1.1.30-src/jni/native# make
make[1]: Entering directory `/usr/local/tomcat/apache-tomcat-7.0.54/bin/tomcat-native-1.1.30-src/jni/native'

因此，在开始下面步骤之前，请先安装libssl-dev
apt-get install libssl-dev
从http://apr.apache.org/download.cgi下载apr,apr-util,apr-iconv.
传输完安装apr:
tar zxvf apr-1.5.2.tar.gz cd apr-1.5.2 ./configure --prefix=/usr/local/apr make make install
安装apr-iconv:
tar zxvf apr-iconv-1.2.1.tar.gz cd apr-iconv-1.2.1 ./configure --with-apr=/usr/local/apr make make install
安装apr-util:
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:首先到tomcat/bin目录下,找到对应的tar文件.
tar zxvf tomcat-native.tar.gz
cd tomcat-native-1.1.30-src/jni/native/
./configure
--with-apr=/usr/local/apr
--with-java-home=/usr/local/jdk/jdk1.7.0_60
--with-ssl=/usr/bin
make
make install
备注：
--with-java-home 后面是本机的jdk安装目录
参数--with-ssl=/usr/bin 必须加上，服务器的ssl目录，否则启动tomcat会报错，SEVERE: Failed to initialize the SSLEngine.
org.apache.tomcat.jni.Error: 70023: This function has not been implemented on this platform
安装完成之后 会出现如下提示信息
Libraries have been installed in: /usr/local/apr/lib
添加环境变量: vi /etc/profile在文件末尾处添加下面的变量
export LD_LIBRARY_PATH=/usr/local/apr/lib
然后执行下面命令，使环境变量即时生效
source /etc/profile
启动tomcat，你看到如下的信息，表示apr生效
