Zero, configure Tomcat
By default, Tomcat does not have user role permissions configured.
However, subsequent Jenkins deployment projects to Tomcat server need to use Tomcat users, so modify the following configuration of Tomcat, add users and permissions
vi /opt/tomcat/conf/tomcat-users.xml
# 内容如下:
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-status"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<user username="tomcat" password="tomcat" roles="manager-gui,manager-script,tomcat,admin-gui,admin-script"/>
User and password are: tomcat Note: In order to log in to Tomcat by the user just configured, the following configuration needs to be modified
vi /opt/tomcat/webapps/manager/META-INF/context.xml
<!--
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
-->
# 把上面这行注释掉即可!
Restart Tomcat, access test,
enter tomcat tomcat to
configure Tomcat credentials
1. Remote deployment of war packages for free style projects
1. Create a free style project

Second, create a pipeline project to remotely deploy the war package
The project selection is Pipeline流水线项目,
- The concept
Pipeline, in simple terms, is a set of workflow frameworks running on Jenkins, which
connects tasks that originally run independently on a single or multiple nodes to achieve complex process orchestration and visualization work that is difficult to complete with a single task. - The use of Pipeline has the following benefits (from the official document translation):
Code: Pipeline is implemented in the form of code and is usually checked into source control, enabling the team to edit, review and iterate its delivery process. Durable: Whether it is a planned or unplanned server restart, Pipeline is recoverable. Can be stopped: Pipeline can receive interactive input to determine whether to continue the pipeline. Multi-function: Pipeline supports complex continuous delivery requirements in the real world. It supports fork/join, loop execution, and parallel execution of tasks. Extensible: The Pipeline plug-in supports custom extensions of its DSL, as well as multiple options for integration with other plug-ins. - How to create Jenkins Pipeline?
Pipeline script is implemented by Groovy language, but we don’t need to learn Groovy
Pipeline separately. It supports two grammars: Declarative (declarative) and Scripted Pipeline (scripted) grammar.
Pipeline also has two creation methods: Yes Enter the script directly in the Jenkins Web UI interface; you can also create a Jenkinsfile script file and put it into the project source code library (generally we recommend loading the Jenkinsfile Pipeline directly from the source code control (SCM) in Jenkins) ).
Install the Pipeline plug-in Manage Jenkins->Manage Plugins->Optional plug
-ins After installing the plug-ins, there are more "pipeline" types when creating projects
1. Pull the code
Configure git repository, click流水线语法
Click to generate pipeline script
2. Build and compile
stage('编译构建') {
steps {
sh label: '', script: 'mvn clean package -Dmaven.test.skip=true'
}
}
3. Remote deployment
Click to generate pipeline script
stage('远程部署') {
steps {
deploy adapters: [tomcat8(credentialsId: 'a2672517-c02b-4f62-ab3c-e6f70d08b98e', path: '', url: 'http://wangyitong.club:8080/')], contextPath: null, war: 'target/*.war'
}
}
Full script:
pipeline {
agent any
stages {
stage('拉取代码') {
steps {
checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '614e4281-db76-4388-befc-c50588f5e751', url: 'https://gitee.com/L1692312138/ssm_web_war_jenkins.git']]])
}
}
stage('编译构建') {
steps {
sh label: '', script: 'mvn clean package -Dmaven.test.skip=true'
}
}
stage('构建完成') {
steps {
echo '构建完成'
}
}
stage('远程部署') {
steps {
deploy adapters: [tomcat8(credentialsId: 'a2672517-c02b-4f62-ab3c-e6f70d08b98e', path: '', url: 'http://wangyitong.club:8080/')], contextPath: null, war: 'target/*.war'

Installation Pipeline Script from SCM plugin
we just are writing code directly in Jenkins Pipeline UI interface, so the script is not convenient maintenance, it is recommended to put script Pipeline
in the project (with version control) 1) establish Jenkinsfile file in the root directory of the project, Copy the content to the file
2) Reference the file in the project
Click Build to view the console output
Second, deploy the jar package
1. Create a free style project
Process:
Add post-build operation steps, then configure ssh information, write scripts, then execute the scripts after sending the package, stop the process, and start the process.
2. Install Publish Over SSH plugin
Publish Over SSH plugin
Then configure ssh
3. Add build steps to compile and package
4. Add post-build operation steps
Configuration project--"Add Sned build artifacts over SSH for post-build operation steps
-
Source files directory after the project is built
-
Remove prefix
-
Remote directoty release directory
-
Exec command issued the executed command
5. Write a shell script
First find the port number of the running project by the project name, if it exists, kill the process,
and then restart the project again.
shell script:
#!/bin/env bash
#PID=`ps -ef |grep 项目名称 |grep -v grep | awk '{print $2}'`
PID=`ps -ef |grep 'wxthepublic-1.0-SNAPSHOT.jar' |grep -v grep | awk '{print $2}'`
if [ ! "$PID" ]
then # 这里判断TOMCAT进程是否存在
echo $PID"进程不存在"
else
echo "进程存在 杀死进程PID$PID"
kill -9 $PID
fi
nohup java -jar 'wxthepublic-1.0-SNAPSHOT.jar' >/dev/null 2>log &
#根据重启后是否有当前应用判断启动是否成功
pid=$(ps -ef | grep java| grep 'wxthepublic-1.0-SNAPSHOT.jar'|awk -F '[ ]+' '{print $2}')
echo $pid
if [ -z $pid ]
then
echo "启动失败"
exit 1
else
echo 'wxthepublic-1.0-SNAPSHOT.jar' : $pid "启动成功"
fi
6. Build now
