Tomcat 安装与配置规范

Tomcat 安装

演示版本:8.5.32 安装版

JDK推荐版本:jdk1.8

下载地址:https://tomcat.apache.org/download-80.cgi

安装教程

注意:tomcat8.5以后的版本,这样配置是无法进入管理页面的,客户端进入tomcat首页点击manager想进行项目管理发现没有登录提示,直接跳转403或401权限错误。我们需要修改相应的配置文件方可访问。

修改:/webapps/magager/META-INF/context.xml

原文为:

<Context antiResourceLocking="false" privileged="true" >
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

 

修改为:

<Context antiResourceLocking="false" privileged="true" >
   
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="^.*$" />

 <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

 

tomcat并发调优处理:

 修改server.xml

<Executor name="tomcatThreadPool" 
            namePrefix="HTTP-8115-exec-" 
            prestartminSpareThreads="true" 
            maxThreads="5000" 
            minSpareThreads="20" 
            maxSpareThreads="50" 
            maxIdleTime="1000"/>

     <Connector executor="tomcatThreadPool"
               port="8115" protocol="org.apache.coyote.http11.Http11NioProtocol"
               URIEncoding="UTF-8"
               connectionTimeout="30000"
               enableLookups="false"
               disableUploadTimeout="false"
               connectionUploadTimeout="150000"
               acceptCount="300"
               keepAliveTimeout="120000"
               maxKeepAliveRequests="1"
               compression="on"
               compressionMinSize="2048"
               compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,image/gif,image/jpg,image/png" 
               redirectPort="8443" />

 

增加全局错误页面处理

准备一个错误处理页面404.html和500.html(内容自定义)

把error.html放到\webapps\ROOT目录下

修改web.xml增加下图代码

<error-page>
        <exception-type>java.lang.Exception</exception-type>
        <location>/500.html</location>
    </error-page>
    <error-page>
        <error-code>404</error-code>
        <location>/404.html</location>
    </error-page>
    <error-page>
        <error-code>500</error-code>
        <location>/500.html</location>
    </error-page>

 

增加tomcatq启动内存

-XX:PermSize=512M
-XX:MaxPermSize=1024M
