关闭主站

[[email protected] ~]# bash /usr/local/tomcat/bin/shutdown.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/javaUsing CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

 

准备多实例主目录

[[email protected] ~]# mkdir  /usr/local/tomcat/instance{1..3}

制作实例工作目录

[[email protected] ~]# cp -r /usr/local/tomcat/{conf,logs,temp,work} /usr/local/tomcat/instance1/
[[email protected] ~]# cp -r /usr/local/tomcat/{conf,logs,temp,work} /usr/local/tomcat/instance2/
[[email protected] ~]# cp -r /usr/local/tomcat/{conf,logs,temp,work} /usr/local/tomcat/instance3/

查看目录结构

[[email protected] ~]#  tree -d -L 2 /usr/local/tomcat/
/usr/local/tomcat/
