1、问题描述：换过tomcat版本，换过jdk版本，也换过tomcat/bin/下的tomcat-native,以及以为是ssl证书的问题。 1）、启动tomcat后，查看netstat -tlnpu查看端口8443端口一直起不来。 2）、查看log日志有如下错误 The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path：
2、查看jdk是否安装,如未安装，请安装（我这里直接rpm包安装的）#rpm -qa |grep jdk#sudo rpm -ivh jdk-**.rpm
3、查看apr是否安装（如未安装，请安装）#rpm -qa |grep apr#sudo yum install -y apr apr-devel
4、安装tomcat-native (在tomcat/bin/下)#sudo tar zxvf tomcat-native.tar.gz #cd tomcat-native-1.1.14-src/native #sudo ./configure --with-java-home=/usr/java/jdk1.8.0_60/#sudo make #sudo make install
5、设置 apr 的环境变量：#vi /etc/profile #追加到最后面 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib #source /etc/profile
6、附上server.xml的配置截取ssl如下<Connector port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol" maxThreads="150" SSLEnabled="true" > <SSLHostConfig> <Certificate SSLCertificateFile="/home/yingjiahulian_BOS/tomcat/conf/ssl/certs/rickricks.com-cert.cer" SSLCertificateKeyFile="/home/yingjiahulian_BOS/tomcat/conf/ssl/private/rickricks.com.key" type="RSA" /> </SSLHostConfig></Connector>
