Intellij IDEA remote tomcat debug with jrebel on linux
Intellij IDEA remote tomcat debug with jrebel on linux
Github:
https://github.com/crabdave/Docker-jrebel-debug.git
1、准备jrebel.jar文件 ，生产jrebel服务端密码
java -jar /opt/jrebel.jar -set-remote-password 12345678
2、修改catalina.sh文件指定debug端口、jrebel热部署端口等 ，添加
export JAVA_OPTS="-javaagent:/opt/jrebel.jar -Drebel.remoting_plugin=true -Drebel.remoting_port=8000 -agentlib:jdwp=transport=dt_socket,address=58200,suspend=n,server=y"
3、修改tomcat配置，配置支持maven cargo:deploy 远程部署war
#modify tomcat setting
#modify server.xml for manager web page
sed -i '/<\/Host>/i <Context path=\"/manager\" docBase=\"/opt/apache-tomcat-8.0.33/webapps/manager\" debug=\"0\" privileged=\"true\"/>' /opt/a
pache-tomcat-8.0.33/conf/server.xml
#modify tomcat-users.xml for deploy role auth
sed -i '/<\/tomcat-users>/i \<role rolename="admin"/>' /opt/apache-tomcat-8.0.33/conf/tomcat-users.xml
sed -i '/<\/tomcat-users>/i \<user username="admin" password="admin" roles="admin,manager-script,manager-gui"/>' /opt/apache-tomcat-8.0.33/con
f/tomcat-users.xml
#modify web.xml for the war more than 50M
sed -i 's/52428800/-1/g' /opt/apache-tomcat-8.0.33/webapps/manager/WEB-INF/web.xml
4、在Intellij IDEA 配置remote debug
4.1）自动编译java文件
Preferences->Build,Execution,Deployment->Compiler->Make project automatically
手动点编译（在Intellij IDEA 左上，选择 Tomcat 框的左边，向下的绿箭头图标）
4.2）配置remote
Preferences->Jrebel->Remote servers
添加Jrebel使用的地址、端口(前面设置的是8000)和密码（前面设置的是12345678），点击测试，看是否成功（tomcat启动之后才会成功）。
Run->Edit Configurations + Remote ->
指定 address=58200 debug调试端口
module's classpath 指定要debug的项目
Before launch:选择 xxx:war exploded
4.3）Configure modules for remote server support.
View > Tool Windows > JRebel.
把后面两个勾打上
4.4） 本地用maven打包部署到远程tomcat上，
mvn clean compile package cargo:deploy
然后开始同步，debug
在Intellij IDEA 左上，选择 Tomcat 框（选择刚配置的remote）的右边，小虫子是Remote debug按钮,云上的绿火箭是热部署手工同步按钮。
使用Docker容器部署
