一、去官网下载最新版本的[Tomcat][]到/usr/local目录下

二、解压tomcat

tar -zxf apache-tomcat-9.0.16.tar.gz

三、优化catalina.sh文件

vim /usr/local/apache-tomcat-9.0.16/bin/catalina.sh
    
    #在该注释后加入如下代码
    # OS specific support.  $var _must_ be set to either true or false.
    
    export JAVA_OPTS="-server -Xms512M -Xmx1400M -Xss512k -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:+DisableExplicitGC -XX:MaxTenuringThreshold=8 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC  -XX:+CMSParallelRemarkEnabled -XX:LargePageSizeInBytes=128m  -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -Djava.awt.headless=true"

四、优化server.xml文件

vim /usr/local/apache-tomcat-9.0.16/conf/server.xml
    
    #修改内容如下
    <?xml version="1.0" encoding="UTF-8"?>
    <Server port="8005" shutdown="SHUTDOWN">
      <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
      <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
      <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
      <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
      <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
    
      <GlobalNamingResources>
        <Resource name="UserDatabase" auth="Container"
                  type="org.apache.catalina.UserDatabase"
                  description="User database that can be updated and saved"
                  factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
                  pathname="conf/tomcat-users.xml" />
      </GlobalNamingResources>
    
    
      <Service name="Catalina">
        <Connector port="9000" protocol="HTTP/1.1"
    			   URIEncoding="UTF-8"			  
                   maxHttpHeaderSize="8192"
    			   maxThreads="1200"
    			   enableLookups="false"
    			   acceptCount="200"
                   connectionTimeout="20000"
    			   disableUploadTimeout="true"
    			   compression="on"
    			   compressionMinSize="2048"
    			   compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"
                   redirectPort="8443" />
       
        <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    
        <Engine name="Catalina" defaultHost="localhost">
    
          <Realm className="org.apache.catalina.realm.LockOutRealm">   
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                   resourceName="UserDatabase"/>
          </Realm>
    
          <Host name="localhost"  appBase="webapps"
                unpackWARs="true" autoDeploy="true">
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                   prefix="localhost_access_log" suffix=".txt"
                   pattern="%h %l %u %t "%r" %s %b" />
          </Host>
        </Engine>
      </Service>
    </Server>

五、开启tomcat的apr模式

1.  安装apr和gcc

yum -y install apr apr-devel
    yum -y install gcc

1.  安装native

cd /usr/local/apache-tomcat-9.0.16/bin/
    tar xzfv tomcat-native.tar.gz
    cd tomcat-native-1.2.21-src/native/
    ./configure --with-apr=/usr/bin/apr-1-config
    make
    make install

安装完成后会提示  
![在这里插入图片描述][20190307171952369.png]  
3. 整合Tomcat的apr到环境上变量中

vim /etc/profile
    
    #在文件中加入下面这句话
    export CATALINA_OPTS=-Djava.library.path=/usr/local/apr/lib
    
    #使配置生效
    source /etc/profile

1.  修改tomcat的server.xml配置文件

vim tomcat/conf/server.xml
    #将配置中的
    Connector port="8080" protocol="HTTP/1.1"
    改成
    Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol"
    
    将配置中的
    Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
    改成
    Connector port="8009" protocol="org.apache.coyote.ajp.AjpAprProtocol" redirectPort="8443"

重启tomcat，启动日志出现以下内容证明此时以APR模式启动

INFO: Initializing ProtocolHandler ["http-apr-8080"]
    INFO: Initializing ProtocolHandler ["apj-apr-8009"]
