tomcat 常用配置

配置账号和密码，通过gui页面管理tomcat，或者使用maven自动打包部署，都需要配置 /conf/tomcat-users.xml 文件  , 增加类似如下代码：

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

<tomcat-users>

<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"/>

</tomcat-users>

 

/conf/server.xml 文件一般设置

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

<Server port="8089" shutdown="SHUTDOWN">

 

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

  

  <Listener className="org.apache.catalina.core.JasperListener" />

  

  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />

  

  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />

  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

 

<!--  Executor setter 线程池设置-->

<!--

maxThreads：最大线程数

minSpareThreads：线程空闲最少数

maxIdleTime：线程空闲最大时间(毫秒)

maxSpareThreads：线程空闲最大数

acceptCount：当tomcat起动的线程数达到最大时，接受排队的请求个数

-->

<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"

maxThreads="3000"

minSpareThreads="100"

maxIdleTime="60000"

maxSpareThreads="500"

acceptCount="100"

/>

  

  <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">

    

<!-- port:1315 URIEncoding="UTF-8" -->

    <Connector port="8888" protocol="HTTP/1.1" connectionTimeout="20000" 

  redirectPort="8443"  URIEncoding="UTF-8"

  executor="tomcatThreadPool"

  compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"

  

  />

 

    <Connector port="54329" protocol="AJP/1.3" redirectPort="8443" />

 

    <Engine name="Catalina" defaultHost="localhost">

 

    <Realm className="org.apache.catalina.realm.UserDatabaseRealm"

             resourceName="UserDatabase"/>

 

    <Host name="localhost"  appBase="webapps"

            unpackWARs="true" autoDeploy="true"

            xmlValidation="false" xmlNamespaceAware="false">

      <!-- 不带项目名访问<Context path="" reloadable="true" docBase="demo"></Context> -->

    </Host>

 

<!-- directory="d:/data/logs" -->

<!-- directory="/data/logs" -->

<!-- directory="data/logs" -->

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="data/logs/" 

        prefix="localhost_access_log." suffix=".log" 

        pattern="%a`%A`%b`%H`%m`%p`%S`%U`%q`%r`%s`%D`%t" resolveHosts="true"/>

 

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="d:/data/logs/"                             prefix="access_log." suffix=".log"                       pattern="%a`%A`%b`%H`%m`%p`%S`%U`%q`%r`%s`%D`%t" resolveHosts="false"/>

 

    </Engine>

  </Service>

</Server>

 

 

如果一个服务器配置多个tomcat，需要至少修改三个地方，保证tomcat间不会相互影响

NO1:<Server port="8089" shutdown="SHUTDOWN">

NO2:<Connector port="8888" protocol="HTTP/1.1" connectionTimeout="20000" 

NO3:<Connector port="54329" protocol="AJP/1.3" redirectPort="8443" />
