1.安装
需先下载java环境
# 拉取库的配置到本地对应文件
0、wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
1、wget https://pkg.jenkins.io/redhat-stable/jenkins-2.190.1-1.1.noarch.rpm
2、yum install jenkins-2.190.1-1.1.noarch.rpm -y
# 修改配置文件，用户改成了root,端口8020
3、vim /etc/sysconfig/jenkins
JENKINS_USER="root"
JENKINS_PORT="8020"
4、启动
systemctl start jenkins
systemctl enable jenkins
5.查看状态
[root@iZuf6fy2kg5mx828krkhcuZ qqc_data]# systemctl status jenkins

2、使用
2.1 啰嗦几句
ps: 配置了半天也没搞清楚怎么操作，各种选项操作太复杂了；
它的基本流程：手动在服务器执行发布任务命令的过程，进行封装后，可视化页面进行一键批量调用；
本质上就是干了这么一件事，附加了一些用户权限，发布日志记，异常发邮件等相关功能；
有兴趣的同学去jenkins官网(https://www.jenkins.io/zh/doc/)学一下，我暂时学不会啊
2.2 自己实现简易版发布接口
目标：在本地起一个flask 服务，写一个发布接口
(1) 建一个表，存发布日志信息，基本信息如：用户id,发布描述信息，服务器返回的日志等
(2)连接服务器，执行发布命令，日志信息入库，返回
逻辑代码：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
# @Time : 2020/12/10 15:28
# @Author : qqc
# @File : release_tool.py
# @Software: PyCharm
import paramiko
import datetime
import json
from utils.connect_mysql import *
class ReleaseTools(object):
def __init__(self, user_id, params):
self.user_id = user_id
self.params = params
@property
def ssh_connect(self):
""" 连接服务器 """
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 通过ssh 私钥登录
ssh.connect(hostname='47.102.138.171', username='root', key_filename=r'C:\Users\admin\.ssh\id_rsa')
return ssh
@property
def command(self):
""" 发布的命令 """
cmds = " cd /object/test_obj/django_test ; " \
"git pull ; " \
"supervisorctl restart test-django:test-django-uwsgi "
return cmds
def create_release_data(self, info_data):
""" 记录发布日志 """
sql_str = """
INSERT INTO obj_release
(user_id, params_data, out_data,create_time)
VALUES
({0}, '{1}','{2}', NOW());
""".format(self.user_id, self.params, info_data)
cursor_sql(sql_str)
def obj_release(self):
""" 执行入口 """
stdin, stdout, stderr = self.ssh_connect.exec_command(self.command)
out = stdout.readlines()
err = stderr.readlines()
info_data = json.dumps({"out": out, "err": err}, ensure_ascii=False)
self.create_release_data(info_data)
self.ssh_connect.close()
return {"user_id": self.user_id, "params_data": self.params, "out": out, "err": err,
"create_time": datetime.datetime.now()}
调用路由(参数根据实际业务需求调节)：
from flask import Flask, request, jsonify
from utils.release_tool import *
app = Flask(__name__)
@app.route('/get/release')
def release_objects():
user_id = request.args.get("user_id", 0)
params = request.args.get("params", '')
release = ReleaseTools(user_id, params)
res = release.obj_release()
return jsonify(res)
3. 测试
问题：
1、多台服务器发布
2、用户使用权限配置
3、实际生产过程中，通过跳板机连接到生产服务器；
4、可视化页面操作
ps:优化是没完没了的过程，有兴趣的伙伴们来完善起来了啊
