上一頁	第 4 章 Tomcat 安裝與配置	下一頁

2.1. server.xml

			
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

性能調整

			
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               maxThreads="2048" />

	<Connector port="80" protocol="HTTP/1.1"
				maxThreads="2048"
				minSpareThreads="64"
				maxSpareThreads="256"
				acceptCount="128"
				enableLookups="false"
				redirectPort="8443"
				debug="0"
				connectionTimeout="20000"
				disableUploadTimeout="true"
				URIEncoding="UTF-8" />

2.1.1. compression

壓縮傳送數據

				
compression="on"
compressionMinSize="2048"
noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"

2.1.2. useBodyEncodingForURI

如果你的站點編碼非UTF-8,去掉URIEncoding="UTF-8"使用下面選項.

useBodyEncodingForURI="true"

2.1.3. HTTPS

				
   <Connector port="443" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" disableUploadTimeout="true"
               acceptCount="100" scheme="https" secure="true"
               SSLEngine="on"
               SSLCertificateFile="${catalina.base}/conf/localhost.crt"
               SSLCertificateKeyFile="${catalina.base}/conf/localhost.key" />

2.1.4. 隱藏Tomcat版本信息

在Connector中加入server="Neo App Srv 1.0"

				
vim $CATALINA_HOME/conf/server.xml

    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
				maxThreads="8192"
				minSpareThreads="64"
				maxSpareThreads="128"
				acceptCount="128"
				enableLookups="false"
                server="Neo App Srv 1.0"/>

# curl -I http://localhost:8080/
HTTP/1.1 400 Bad Request
Transfer-Encoding: chunked
Date: Thu, 20 Oct 2011 09:51:55 GMT
Connection: close
Server: Neo App Srv 1.0

2.1.5. vhost

傳統配置方式

				
      <Host name="www.example.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
                        <Context path="" docBase="/www/example/www" debug="0" reloadable="false"/>
      </Host>
      <Host name="news.example.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
                        <Context path="" docBase="/www/example/news" debug="0" reloadable="false"/>
      </Host>

建議配置方式

				
vim server.xml

<Engine name="Catalina" defaultHost="neo">
    <Host name="neo"    appBase="neoapps"/>
    <Host name="other" appBase="otherapps"/>
</Engine>

Configuring Your Contexts

				
mkdir $CATALINA_HOME/conf/Catalina/neo

cp $CATALINA_HOME/conf/Catalina/localhost/manager.xml $CATALINA_HOME/conf/Catalina/neo/ROOT.xml

or

cp $CATALINA_HOME/conf/Catalina/localhost/manager.xml $CATALINA_HOME/conf/Catalina/neo

Webapps Directory

				
mkdir $CATALINA_HOME/neo

2.1.6. access_log

				
<Host name="localhost" ...>
  ...
  <Valve className="org.apache.catalina.valves.AccessLogValve"
         prefix="localhost_access_log." suffix=".txt"
         pattern="common"/>
  ...
</Host>

2.2. tomcat-users.xml

			
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>

<role rolename="manager"/>
<user username="tomcat" password="QI0Ajp7" roles="manager"/>

</tomcat-users>

狀態監控 http://localhost/manager/status

服務管理 http://localhost/manager/html/list

			
<tomcat-users>
<!--
  NOTE:  By default, no user is included in the "manager-gui" role required
  to operate the "/manager/html" web application.  If you wish to use this app,
  you must define such a user - the username and password are arbitrary.
-->
<!--
  NOTE:  The sample user and role entries below are wrapped in a comment
  and thus are ignored when reading this file. Do not forget to remove
  <!.. ..> that surrounds them.
-->
<!--
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
-->
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <role rolename="manager-jmx"/>
  <role rolename="manager-status"/>

  <user username="tomcat" password="tomcat" roles="manager-gui,manager-script,manager-jmx,manager-status"/>
  <role rolename="admin-gui"/>
  <role rolename="admin-script"/>
  <user username="admin" password="admin" roles="admin-gui,admin-script"/>

</tomcat-users>

2.3. logging.properties

修改日誌目錄

1catalina.org.apache.juli.FileHandler.level = FINE
#1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.directory = /www/logs/tomcat
1catalina.org.apache.juli.FileHandler.prefix = catalina.
