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
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=22ansible 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 }}"
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/scripteureka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。
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
构建后操作
点击build
直接点开始构建，build_id不需要输入
先查看左侧的build_id
如果要回到上一个版本，选择rollback，输入数字1
点击开始构建，就可以了！
