操作笔记:tomcat在正式环境的常见问题和idea的远程调试
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1,一臺服務器有兩個容器,比如:jetty,tomcat。
出現問題:
jetty啟動的時候,tomcat就不能啟動了。
此時,需要修改tomcat的配置文件:servler.xml

進入toamat安裝目錄下的bin修改catalina.sh。
添加
# ----------------------------------------------------------------------------- # Control Script for the CATALINA Server # # Environment Variable Prerequisites # # Do not set the variables in this script. Instead put them into a script # setenv.sh in CATALINA_BASE/bin to keep your customizations separate. # # CATALINA_HOME May point at your Catalina "build" directory. # # CATALINA_BASE (Optional) Base directory for resolving dynamic portions # of a Catalina installation. If not present, resolves to # the same directory that CATALINA_HOME points to. # # CATALINA_OUT (Optional) Full path to a file where stdout and stderr # will be redirected. # Default is $CATALINA_BASE/logs/catalina.out # # CATALINA_OPTS (Optional) Java runtime options used when the "start", # "run" or "debug" command is executed. # Include here and not in JAVA_OPTS all options, that should # only be used by Tomcat itself, not by the stop process, # the version command etc. # Examples are heap size, GC logging, JMX ports etc.CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=60222,suspend=n,server=y"結合idea的remote,注意:host為服務器的對外ip,port的值需要和上面的添加的address=60222保持一致。
3,用頁面部署項目。
修改的tomcat的conf/tomcat-users.xml文件。
添加
[root@iZ945sgm0ugZ conf]# vim tomcat-users.xml<?xml version='1.0' encoding='utf-8'?> <!--Licensed to the Apache Software Foundation (ASF) under one or morecontributor license agreements.
