這篇是快速配置 Tomcat7 的心得筆記。因為是快速配置，所以只寫重點部份，實務上如有其它需要，請自行查閱官方文件。


我的系統環境如下

• OS：Windows 7
• Tomcat path：Z:\apache-tomcat-7.0.29
• Java version：Java7

設定 Tomcat 啟動時用到的 JVM 相關參數(java home path,gc parameter...etc)

1. 在 Z:\apache-tomcat-7.0.29\bin 目錄裡，自行建立 setenv.bat 與 setenv.sh 。setenv.bat 是給 windows 使用，setenv.sh是給 linux 使用。
2. setenv.bat 的設定可參考下例

   set JAVA_HOME=C:\Java\jdk1.7.0_05
   set JAVA_OPTS=-Xms64m -Xmx384m -XX:+UseParallelGC -Duser.timezone=Asia/Taipei
   

3. setenv.sh 的設定可參考下例

   export JAVA_HOME="/usr/lib/jvm/java-7-sun-1.7.0_05"
   export JAVA_OPTS="-Xms64m -Xmx384m -XX:+UseParallelGC -Duser.timezone=Asia/Taipei"
   

設定 HTTP、HTTPS 連線相關參數

1. 開啟  Z:\apache-tomcat-7.0.29\conf\server.xml
2. 參考下例修改成符合自己所需的設定

   <!--
    port : The TCP port number on which this Connector will create a server socket and await incoming connections.
    protocol : Sets the protocol to handle incoming traffic.
    connectionTimeout : The number of milliseconds this Connector will wait.
    compression : The Connector may use HTTP/1.1 GZIP compression in an attempt to save server bandwidth.
    compressionMinSize : It is used to specify the minimum amount of data before the output is compressed.
    compressableMimeType : The value is a comma separated list of MIME types for which HTTP compression may be used.
   -->
   <Connector port="8080" protocol="HTTP/1.1"
        connectionTimeout="20000"      
        redirectPort="8443" 
        compression="on"
        compressionMinSize="2048" 
        compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css" />
        
   <!--
    port : The TCP port number on which this Connector will create a server socket and await incoming connections.
    protocol : Sets the protocol to handle incoming traffic.
    SSLEnabled : Use this attribute to enable SSL traffic on a connector.
    keystoreFile : The pathname of the keystore file where you have stored the server certificate to be loaded.
    keystorePass : The password used to access the specified keystore file.
   -->      
   <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
        maxThreads="150" scheme="https" secure="true"       
        clientAuth="false" sslProtocol="TLS" 
        keystoreFile="${catalina.base}/conf/.keystore" keystorePass="keystore_password"/>
   

3. 可參考官方文件，進行更仔細的設定

設定 MIME Type Mappings 相關參數

1. 開啟  Z:\apache-tomcat-7.0.29\conf\web.xml
2. 參考下例增加或修改所需的 MIME Type Mappings

   <mime-mapping>
    <extension>pdf</extension>
    <mime-type>application/pdf</mime-type>
   </mime-mapping>
   

設定 Tomcat 系統 Log 要記錄到哪個 level

1. 開啟  Z:\apache-tomcat-7.0.29\conf\logging.properties
2. 設定 Log level。官方文件的重點是這一句「A handler's log level threshold is INFO by default and can be set using SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST or ALL.」
3. 可參考官方文件，進行更仔細的設定
