持续集成-交付-部署-Java 项目
------
## 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 ~]# wget http://182.92.143.66:40072/directlink/img/java-demo/easy-springmvc-maven-master.zip
[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
