Tomcat 安装和配置

安装：

1. 下载安装包解压 http://tomcat.apache.org/download-80.cgi
2. 进入bin文件夹，./startup.sh开启Tomcat，./shutdown.sh关闭Tomcat
3. 进入conf文件夹，配置tomcat-users.xml配置用户
4. 打开localhost:8080/管理Tomcat，经过Tomcat管理界面或者idea部署war包便可部署;]
5. 默认部署到webapps目录下，war的访问前缀为包名springboot.war即为localhost:8080/springboot/

配置：

1. tomcat-users.xml配置用户

   <role rolename="admin-gui"/>   #admin gui用户
   <role rolename="manager-gui”/> #manager gui用户
   <user username="admin" password="admin" roles=" admin-gui , manager-gui "/>

    

2. server.xml配置Tomcat

   <!—配置线程池-->
   <Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
          maxThreads="150" minSpareThreads=“4” maxIdleTime=“60000"/>
   
   <!--设置监听端口，设置共享线程池提升性能-->
   <!--设置为nio protocol="org.apache.coyote.http11.Http11NioProtocol" -->
   <!--tomcat8之后默认为nio -->
   <Connector executor="tomcatThreadPool"
                port="8080" protocol="HTTP/1.1"
                connectionTimeout="20000"
                enableLookups=“false"
                redirectPort="8443" />
   
   <!-- https配置 -->
   <Connector executor="tomcatThreadPool" port="443" protocol="HTTP/1.1" 
               SSLEnabled=“true"  scheme="https" secure="true" clientAuth="false" 
               sslProtocol=“TLS" keystoreFile="conf/tomcat.keystore" keystorePass="123456"/>
   
   <!--设置war目录以及部署属性，能够配置多个Host对应多个域名绑定-->
   <Host name="localhost"
               appBase="webapps"
               unpackWARs="true" autoDeploy="true">

    

3. web.xml配置容许跨域请求

   <filter>
       <filter-name>CorsFilter</filter-name>
       <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
   </filter>
   <filter-mapping>
       <filter-name>CorsFilter</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>

   
    
4. catalina.sh中配置jvm内存，具体参数参考机器配置
   JAVA_OPTS = "-Xmx1024m -Xms1024m -Xmn400m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=0 -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintHeapAtGC -Xloggc:/usr/local/tomcat/logs/gc.log”
   cygwin=false
    
5. server.xml配置静态资源映射
