+------
+
+## 一：环境
+
+| 服务器 | IP地址 | 说明 |
+| ------- | --------------- | -------------- |
+| GitLab | 192.168.159.136 | 私有仓库 |
+| Jenkins | 192.168.159.137 | 自动化部署 |
+| web | 192.168.159.138 | 项目所属服务器 |
+
+三台服务器相互传ssh私钥
+
+## 二：GitLab
+
+### 1. 配置SSH
+
+
+
+
+
+
+
+### 2. 创建项目
+
+
+
+
+
+
+
+
+
+## 三：Jenkins
+
+### 1. 安装插件
+
+```bash
+• Maven插件 Maven Integration plugin
+• 发布插件 Deploy to container Plugin
+• Git 插件 可能已经安装
+• Pipeline Maven Integration:jenkins利用Maven编译，打包所需插件
+• Publish Over SSH:通过ssh连接
+```
+
+### 2. 配置凭证
+
+
+
+
+
+
+
+
+
+**用户密码模式**
+
+
+
+**SSH密钥模式**
+
+
+
+### 3. 配置SSH
+
+
+
+Jenkins服务器私钥传给web服务器
+
+
+
+
+
+### 4. jdk git maven配置
+
+
+
+
+
+Jenkins服务器安装git
+
+
+
+
+
+## 四：web
+
+### 1. 拉取仓库
+
+
+
+```bash
+[root@web ~]# cd /opt
+[root@web opt]# git clone http://192.168.159.136/root/easy-springmvc-maven.git
+```
+
+### 2. 获取测试文件
+
+```bash
+[root@web ~]#
+[root@web ~]# cp -r easy-springmvc-maven-master/* /opt/easy-springmvc-maven/
+```
+
+### 3. 上传代码
+
+```bash
+[root@web easy-springmvc-maven]# git add .
+[root@web easy-springmvc-maven]# git commit -m "first"
+[root@web easy-springmvc-maven]# git push
+```
+
+### 4. 安装jdk tomcat
+
+```bash
+[root@web ~]# tar xf jdk-8u211-linux-x64.tar.gz -C /usr/local/
+[root@web ~]# ln -s /usr/local/jdk1.8.0_211/ /usr/local/jdk8
+[root@web ~]# vim /etc/profile
+JAVA_HOME=/usr/local/jdk8
+MAVEN_HOME=/usr/local/maven
+PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
+export PATH JAVA_HOME MAVEN_HOME
+
+[root@web ~]# source /etc/profile
+[root@web ~]# mkdir -p /data/application
+[root@web ~]# wget https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.104/bin/apache-tomcat-9.0.104.tar.gz
+[root@web ~]# tar xf apache-tomcat-9.0.104.tar.gz -C /data/application/
+[root@web ~]# mv /data/application/apache-tomcat-9.0.104/ /data/application/tomcat
+[root@web ~]# vim /data/application/tomcat/conf/server.xml
+取消8009的注释
+
+
+```
+
+### 5. 编写脚本
+
+```bash
+[root@web ~]# vim /opt/jenkins.sh
+#!/usr/bin/bash
+
+#Defining variables
+export JAVA_HOME=/usr/local/java
+webapp_path="/data/application/tomcat/webapps"
+tomcat_run="/data/application/tomcat/bin"
+updata_path="/data/update/`date +%F-%T`"
+backup_path="/data/backup/`date +%F-%T`"
+tomcat_pid=`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`
+files_dir="easy-springmvc-maven"
+files="easy-springmvc-maven.war"
+job_path="/root/upload"
+
+#Preparation environment
+echo "Creating related directory"
+mkdir -p $updata_path
+mkdir -p $backup_path
+
+echo "Move the uploaded war package to the update 2directory"
+mv $job_path/$files $updata_path
+
+echo "========================================================="
+cd /opt
+echo "Backing up java project"
+if [ -f $webapp_path/$files ];then
+ tar czf $backup_path/`date +%F-%H`.tar.gz $webapp_path
+ if [ $? -ne 0 ];then
+ echo "打包失败，自动退出"
+ exit 1
+ else
+ echo "Checking if tomcat is started"
+ if [ -n "$tomcat_pid" ];then
+ kill -9 $tomcat_pid
+ if [ $? -ne 0 ];then
+ echo "tomcat关闭失败，将会自动退出"
+ exit 2
+ fi
+ fi
+ cd $webapp_path
+ rm -rf $files && rm -rf $files_dir
+ cp $updata_path/$files $webapp_path
+ cd /opt
+ $tomcat_run/startup.sh
+ sleep 5
+ echo "显示tomcat的pid"
+ echo "`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`"
+ echo "tomcat startup"
+ echo "请手动查看tomcat日志。脚本将会自动退出"
+ fi
+else
+ echo "Checking if tomcat is started"
+ if [ -n "$tomcat_pid" ];then
+ kill -9 $tomcat_pid
+ if [ $? -ne 0 ];then
+ echo "tomcat关闭失败，将会自动退出"
+ exit 2
+ fi
+ fi
+ cp $updata_path/$files $webapp_path
+ $tomcat_run/startup.sh
+ sleep 5
+ echo "显示tomcat的pid"
+ echo "`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`"
+ echo "tomcat startup"
+ echo "请手动查看tomcat日志。脚本将会自动退出"
+fi
+[root@web ~]# chmod +x /opt/jenkins
+```
+
+## 五：jenkins创建项目
+
+### 1. 创建项目
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### 2. 构建
