安装了pakets

APR-1.3.9-5.el6_2.x86_64

Tomcat的7.0.70-2.el6.noarch

的OpenSSL 1.0.1e-48.el6_8.3.x86_64

Tomcat的本机1.1.34-1.el6.x86_64

java的1.8.0-的openjdk-1.8.0.101-3.b13.el6_8.x86_64

操作系统：CentOS

如何解决此错误？

Answer 1

尝试升级您的库。将此代码运行到终端：

sudo apt-get upgrade libtcnative-1

它应该解决问题。

Answer 2

在这种情况下，APR库可能缺少tc-native的ssl连接器的库，修复如下：

        . yum install apr-devel openssl-devel
        . download into $CATALINA_HOME/conf/tomcatnative and unpack the file tomcat-native-1.2.23-src.tar.gz
        . goto /native and run a command, this is the syntax
            ./configure --with-apr=$HOME/APR \
                        --with-java-home=$JAVA_HOME \
                        --with-ssl=$HOME/OPENSSL \
                        --prefix=$CATALINA_HOME

            And this is the real command
            ./configure --with-apr=/usr/bin/apr-1-config --with-java-home=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-2.b14.el7.x86_64 --with-ssl=/usr/bin --prefix=/opt/tomcat

        . then run 'make && make install'
            (should have 'done' in the result without errors)
            (generated libs of tcnative are found under $CATALINA_HOME/lib)

        . under server.xml make sure below line exists
            <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

        . Edit $CATALINA_HOME/bin/setenv.sh (creating the file if necessary) and add the path to the tc-native libraries to LD_LIBRARY_PATH
            'LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CATALINA_HOME/lib'
            'export LD_LIBRARY_PATH'

    - now start tomcat and test, the following should be seen in logs/catalina.out 
        09-Apr-2020 12:16:07.075 INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent Loaded APR based Apache Tomcat Native library [1.2.23] using APR version [1.4.8].

        . then test https://ip:8443/tx, should be accessible

Tomcat和APR lib：需要不可用的APR /本机库
