nginx 설정

- ip_hash

/etc/nginx/conf.d/default.conf

upstream backend_tomcat {
        ip_hash;
        server 192.168.0.62:8082;
        server 192.168.0.62:8083;
        server 192.168.0.63:8082;
        server 192.168.0.63:8083;
        #keepalive 100;
    }

tomcat server.xml 설정

vim /apps/tomcat/instance1/conf/server.xml

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

    <Connector port="8082" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <!--
    <Connector protocol="AJP/1.3"
               address="::1"
               port="8009"
