Tomcat 安裝和配置

安裝：

1. 下載安裝包解壓 http://tomcat.apache.org/download-80.cgi
2. 進入bin文件夾，./startup.sh開啓Tomcat，./shutdown.sh關閉Tomcat
3. 進入conf文件夾，配置tomcat-users.xml配置用戶
4. 打開localhost:8080/管理Tomcat，經過Tomcat管理界面或者idea部署war包便可部署;]
5. 默認部署到webapps目錄下，war的訪問前綴爲包名springboot.war即爲localhost:8080/springboot/

配置：

1. tomcat-users.xml配置用戶

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

    

2. server.xml配置Tomcat

   <!—配置線程池-->
   <Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
          maxThreads="150" minSpareThreads=「4」 maxIdleTime=「60000"/>
   
   <!--設置監聽端口，設置共享線程池提升性能-->
   <!--設置爲nio protocol="org.apache.coyote.http11.Http11NioProtocol" -->
   <!--tomcat8之後默認爲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"/>
   
   <!--設置war目錄以及部署屬性，能夠配置多個Host對應多個域名綁定-->
   <Host name="localhost"
               appBase="webapps"
               unpackWARs="true" autoDeploy="true">

    

3. web.xml配置容許跨域請求

   <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內存，具體參數參考機器配置
   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配置靜態資源映射
