jenkins发布Spring Cloud(单机版)

一、概述

有一台测试服务器，需要部署Spring Cloud。通过Jenkins来发布！

环境说明

gitlab版本：GitLab 社区版 10.5.1

jenkins版本：2.219

测试服务器：操作系统为centos7.6

项目说明

微服务统一在一个git项目里面，项目的大致结构如下：

./
├── auth-server
│   ├── pom.xml
│   └── src
├── common
│   ├── pom.xml
│   └── src
├── config-server
│   ├── pom.xml
│   └── src
├── eureka-server
│   ├── pom.xml
│   └── src
├── gateway
│   ├── pom.xml
│   └── src
├── pom.xml
└── service-user
    ├── pom.xml
    └── src

主要有5个微服务器，分别是eureka，config，auth，user，gateway

二、ansible配置

增加分组

修改文件/etc/ansible/hosts，增加一个分组

[test_java]
192.168.28.229 ansible_ssh_port=22

ansible playbook

登录到jenkins服务器，创建目录

mkdir -p /opt/ansible/test

发布模板

vi /opt/ansible/test/deploy_standard_template.yml

内容如下：

---
 - hosts: "{{ HOSTS }}"
   remote_user: root
   become: yes
   become_method: sudo
   # 需要传入变量HOSTS,ENV，PROJECT_NAME，PREFIX，PORT
   # 分别表示主机,环境，项目名，路径前缀(拼接jenkins jar包路径)，端口。
   # 声明变量
   vars:
     # 远程项目基础目录
     BASE_DIR: "/data/code"
     # 远程项目目录名
     PROJECT_DIR: "{{ ENV }}_{{ PROJECT_NAME }}_{{ PORT }}"
     # 备份目录
     BAK_DIR: "/data/website_backup"
     # 完整的jenkins jar包路径
     JENKINS_JAR: "/data/jenkins_data/workspace/{{ JOB_NAME }}/{{ PREFIX }}/target/{{ PROJECT_NAME }}.jar"
   tasks:
    #删除原来的包
     - name: move old package
       file: path={{ BASE_DIR }}/{{ PROJECT_DIR }}/{{ PROJECT_NAME }}.jar state=absent
    #同步jar包到目标服务器
     - name: synchronize package to {{ PROJECT_NAME }}
       synchronize:
         src: "{{ JENKINS_JAR }}"
         dest: "{{ BASE_DIR }}/{{ PROJECT_DIR }}/"
    #修改包的属性
     - name:  modify package
       file:  path="{{ BASE_DIR }}/{{ PROJECT_DIR }}/{{ PROJECT_NAME }}.jar" owner=root group=root
    # 备份当前的包
     - name: backup jar
       shell: "mkdir -p {{ BAK_DIR }}/{{ PROJECT_DIR }}_rollback/{{ BUILD_NUMBER }}/;cp -a {{ BASE_DIR }}/{{ PROJECT_DIR }}/{{ PROJECT_NAME }}.jar {{ BAK_DIR }}/{{ PROJECT_DIR }}_rollback/{{ BUILD_NUMBER }}/;chown -R root:root {{ BAK_DIR }}/{{ PROJECT_DIR }}_rollback"
    #启动server
     - name: start
       shell: "/opt/script/{{ PROJECT_DIR }} restart"
     - name: view port,Wait for 90 seconds
       shell: "sleep 90;lsof -t -i:{{ PORT }}"

回滚模板

vi /opt/ansible/test/rollback_standard_template.yml

内容如下：

---
 - hosts: "{{ HOSTS }}"
   remote_user: root
   become: yes
   become_method: sudo
   # 需要传入变量HOSTS，ENV，PROJECT_NAME，PORT，BUILD_ID
   # 分别表示主机，环境，项目名，端口，回滚的构建ID
   # 声明变量
   vars:
     # 远程项目基础目录
     BASE_DIR: "/data/code"
     # 远程项目目录名
     PROJECT_DIR: "{{ ENV }}_{{ PROJECT_NAME }}_{{ PORT }}"
     # 备份目录
     BAK_DIR: "/data/website_backup"
   tasks:
    # 还原指定的包
     - name: reduction package
       shell: "\\cp -a {{ BAK_DIR }}/{{ PROJECT_DIR }}_rollback/{{ BUILD_ID }}/{{ PROJECT_NAME }}.jar {{ BASE_DIR }}/{{ PROJECT_DIR }}/{{ PROJECT_NAME }}.jar"
    #启动server
     - name: start
       shell: "/opt/script/{{ PROJECT_DIR }} restart"
     - name: view port,Wait for 80 seconds
       shell: "sleep 80;lsof -t -i:{{ PORT }}"

三、服务器配置

jdk配置

登录测试服务器，创建代码目录

mkdir -p /data/code

安装rsync，用于jenkins同步代码

yum install -y rsync

安装jdk，这里就不做描述了。请参考链接：

https://www.cnblogs.com/xiao987334176/p/11678894.html

java启动脚本

创建脚本目录

mkdir /opt/script

eureka启动脚本

vi /opt/script/test_eureka-server_8761

内容如下

#!/bin/bash
# auditd        Start jar package
# chkconfig: 2345 14 87
# description: This is admin project
#define var

export JAVA_BIN=/data/jdk1.8.0_211/
export JAR_NAME=eureka-server.jar
export PROJECT_SERVICE=eureka-server
export ENV=test
export XMS=512m
export XMX=512m
export PORT=8761
export PROJECT_HOME=/data/code/${ENV}_${PROJECT_SERVICE}_${PORT}

. /etc/init.d/functions 
export START="nohup ${JAVA_BIN}bin/java -Xms${XMS} -Xmx${XMX} -XX:MetaspaceSize=50M -XX:MaxMetaspaceSize=256m -jar ${PROJECT_HOME}/${JAR_NAME} &"

#服务脚本
start(){
    echo "${PROJECT_SERVICE} starting....."
    source /etc/profile && cd $PROJECT_HOME && eval $START 
    if [ $? -eq 0 ];then
            action "$PROJECT_SERVICE is starting" /bin/true
    else
            action "$PROJECT_SERVICE is starting" /bin/false
    fi
}
stop(){
    for i in $(ps -aux|grep ${JAR_NAME}|grep -v grep|awk '{print $2}');do
            kill -9 $i;
    done
    if [ $? -eq 0 ];then
        action "$PROJECT_SERVICE is stoping" /bin/true
    else
        action "$PROJECT_SERVICE is stoping" /bin/false
    fi 
}
status(){
    if [ `ss -tunlp|grep ${PORT}|awk '{print $5}'|cut -d: -f2` = ${PORT} ];then
            echo "${PROJECT_SERVICE} is running....."
    else
            echo "${PROJECT_SERVICE} is stopping....."
    fi
}
case $1 in
start)
    start
    ;;
stop)
    stop
    ;;
restart)
    stop
    start
    ;;
status)
    status
    ;;
*)
   echo "$0 <start|stop|restart>"
esac

添加执行权限

chmod 755 /opt/script/test_eureka-server_8761

其它4个微服务脚本也是同样的，注意修改项目名和端口号。

四、jenkins配置

确保jenkins已经安装了插件：Git Parameter

新建job

名为：test_eureka-server，选择自由风格的。

参数化构建

指定分支

build参数

构建后执行shell脚本

完整内容如下：

case $Status  in
  Deploy)
    echo "Status:$Status"
    ansible-playbook -v /opt/ansible/test/deploy_standard_template.yml -e "HOSTS=test_java JOB_NAME=${JOB_NAME} BUILD_NUMBER=${BUILD_NUMBER} ENV=test PROJECT_NAME=eureka-server PREFIX=eureka-server PORT=8761"
    echo "Completing!"
    ;;
  Rollback)
    echo "Status:$Status"
    echo "BUILD_ID:$BUILD_ID"
    ansible-playbook -v /opt/ansible/test/rollback_standard_template.yml -e "HOSTS=test_java ENV=test PROJECT_NAME=eureka-server PORT=8761 BUILD_ID=${BUILD_ID}"
    echo "Completing!"
    ;;
  *)
  exit
    ;;
esac
