需要在作業系統中安裝libtcnative庫

一、環境準備

1.1 安裝APR

下載apr-1.7.0.tar.gz、apr-util-1.6.1.tar.gz ，下載地址https://mirror.bit.edu.cn/apache/apr/

上傳至/home 目錄下後解壓；

執行：

#cd /home/apr-1.7.0
#./configure
#make
#make install

cd /home/apr-util-1.6.1
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make
make install

1.2 下載安裝openSSL，地址

cd /home/openssl
./config
make
make install

1.3 下載安裝Tomcat Native，地址http://tomcat.apache.org/download-native.cgi

同樣解壓後執行：

cd /home/tomcat-native-1.2.24-src/native
./configure --with-apr=/usr/local/apr --with-ssl=/usr/local/openssl --with-java-home=${JAVA_HOME}
make
make install

1.4 配置 /etc/profile 檔案，在末尾追加紅色資訊：

unset i
unset -f pathmunge

if [ -n "${BASH_VERSION-}" ] ; then
        if [ -f /etc/bashrc ] ; then
                # Bash login shells run only /etc/profile
                # Bash non-login shells run only /etc/bashrc
                # Check for double sourcing is done in /etc/bashrc.
                . /etc/bashrc
       fi
fi

export JAVA_HOME
 
=/usr/java/jdk1.8.0_131
export JRE_HOME=${JAVA_HOME}/jre
export HADOOP_HOME=/home/hadoop-3.3.0
export HIVE_HOME=/home/hive-3.1.2
export CLASSPATH=$($HADOOP_HOME/bin/hadoop classpath):$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH:$HIVE_HOME/bin:$JAVA_HOME/bin
export LD_LIBRARY_PATH=/usr/local/apr/lib:$LD_LIBRARY_PATH

二、配置tomcat 8.5

1、在/home/apache-tomcat-8.5-jjdemo/bin 目錄中建立setenv.sh檔案， 內容如下：

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CATALINA_HOME/lib
export LD_LIBRARY_PATH

2、修改server.xml 檔案的Connector 節點資訊：

    <Connector port="996"               keepAliveTimeout="15"
               maxKeepAliveRequests="200"
               maxThreads="5000"
               minSpareThreads="50"
               acceptCount="500" 
               acceptorThreadCount="500"
               URIEncoding="UTF-8"
               enableLookups="false"
               compression="on"
               compressionMinSize="10240"
               noCompressionUserAgents="gozilla,traviata"
               compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"
               connectionTimeout="20000"
               disableUploadTimeout="true"
               protocol="org.apache.coyote.http11.Http11Nio2Protocol"
               SSLEnabled="true" >
         <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
         <SSLHostConfig>
            <Certificate certificateKeyFile="conf/cert/4016613_jjdemo.xuetz.com.key"
                         certificateFile="conf/cert/4016613_jjdemo.xuetz.com.pem"
                         type="RSA" />
         </SSLHostConfig>
    </Connector>    

其中證書從阿里雲SSL證書的“其他”類別中下載：

3、重啟tomcat 檢視日誌資訊，出現以下資訊表示配置成功：

27-Aug-2020 11:01:51.545 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Djava.io.tmpdir=/home/apache-tomcat-8.5-jjdemo/temp

4、訪問頁面後，檢視localhost_access_log.2020-08-27.txt 檔案，出現HTTP/2.0表示執行成功：
