Tomcat常设参数

1、docBase：设置成这种样式后，js修改后无需重新发布
 <Context docBase="D:\svn\scim\trunk\scim\WebContent" path="/" reloadable="false"/>

2、maxHttpHeaderSize：request请求参数最大

 <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" maxHttpHeaderSize="131072" maxPostSize="4194304"/>

3、修改JSESSIONID的名字，防止多个tomcat发布一个web时，帐号互踢
 <Context sessionCookieName="JSP_SessionId">//session、cookie

 4、tomcat的几个端口：port="8080" http访问端口、redirectPort="8443" https访问端口、port="8005" 远程停服务端口、port8009AJP端口，APACHE能过AJP协议访问TOMCAT的8009端口
  <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="60000"
     redirectPort="8443" disableUploadTimeout="false" executor="tomcatThreadPool" URIEncoding="UTF-8"/>
    <Server port="8005" shutdown="SHUTDOWN">
  <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />  

5、一个tomcat部署多个项目:复制多个<service></service>节点，修改8080端口、注释8009端口、修改appBase
     <!-- the first service-->  
  <Service name="Catalina">  
      <Connector port="80" protocol="HTTP/1.1"  
                connectionTimeout="20000"  
                redirectPort="8443" />  
       <!-- 注释的地方-->  
       <!-- <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>       

   <!-- the second service-->  
       
     <Service name="Catalina">  
     <!-- 修改的地方-->  
     <Connector port="8081" protocol="HTTP/1.1"  
                connectionTimeout="20000"  
                redirectPort="8443" />  
                 -->  
   <!-- 注释的地方-->  
   <!--<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>  
         <!-- 修改的地方 appBase：第二个项目放置的位置-->  
       <Host name="localhost"  appBase="webapps1"  
             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>  

6、一个环境中部署多个tomcat//增加环境变量CATALINA_HOME2，值为新的tomcat的地址；增加环境变量CATALINA_BASE2，值为新的tomcat的地址。

//修改新的tomcat中的startup.bat、shutdown.bat，把其中的CATALINA_HOME改为CATALINA_HOME2。

//修改新的tomcat中的catalina.bat，把其中的CATALINA_HOME改为CATALINA_HOME2，CATALINA_BASE改为CATALINA_BASE2。

//修改conf/server.xml文件
  <Server port="8005" shutdown="SHUTDOWN">把端口改为没有是使用的端口。    
    <Connector port="8080" maxHttpHeaderSize="8192"    
     maxThreads="150" minSpareThreads="25" maxSpareThreads="75"    
     enableLookups="false" redirectPort="8443" acceptCount="100"    
     connectionTimeout="20000" disableUploadTimeout="true" /> 把端口改为没有是使用的端口。    
    <Connector port="8009"enableLookups="false" redirectPort="8443" protocol="AJP/1.3" /> 把端口改为没有是使用的端口。 

7、一个完整的tomcat server.xml配置文件。
 <?xml version="1.0" encoding="UTF-8"?>
   <Server port="8005" shutdown="SHUTDOWN">
     <Service name="Catalina">
       <Connector connectionTimeout="20000" maxHttpHeaderSize="131072" maxPostSize="4194304" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
       <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>
       <Engine defaultHost="localhost" name="Catalina">
           <Realm className="org.apache.catalina.realm.LockOutRealm">
           <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
           </Realm>
       <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">
         <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log" suffix=".txt"/> 
         <Context docBase="D:\svn\scim\trunk\scim\scim_web\WebContent" path="/" reloadable="false"/>
       </Host>
     </Engine>
   </Service>
 </Server>
