开启监控

tomcat-users.xml

<role rolename="manager-gui"/>
<role rolename="manager-jmx"/>
<user username="hbzw2023" password="hbzw2023#3202" roles="manager-gui, manager-jmx"/>

内存优化

startup.sh

export CATALINA_OPTS=" -server -Dfile.encoding=UTF-8 -Xms4096m -Xmx4096m -XX:PermSize=256M -XX:MaxNewSize=256m -XX:MaxPermSize=1024m "

连接优化

<!--The connectors can use a shared executor, you can define one or more named thread pools-->
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
    maxThreads="500" 
    minSpareThreads="50"  　　    prestartminSpareThreads="true" 
    maxQueueSize="1000" />

<!-- A "Connector" represents an endpoint by which requests are received
     and responses are returned. Documentation at :
     Java HTTP Connector: /docs/config/http.html
     Java AJP  Connector: /docs/config/ajp.html
     APR (HTTP/AJP) Connector: /docs/apr.html
     Define a non-SSL/TLS HTTP/1.1 Connector on port 8080
-->
<Connector port="8080" protocol="HTTP/1.1"
           address="192.168.2.110"
           executor="tomcatThreadPool"               
           protocol="org.apache.coyote.http11.Http11NioProtocol"
           connectionTimeout="20000"
           redirectPort="8443" />

允许ip访问

server.xml

Connector 中添加address
::1 是IPV6
192.168.2.100, 192.168.2.101 可以多个
