1.安裝

需先下載java環(huán)境
# 拉取庫的配置到本地對應文件
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，用戶改成了root,端口8020
3、vim /etc/sysconfig/jenkins 
JENKINS_USER="root"
JENKINS_PORT="8020"

4、啟動
systemctl start jenkins
systemctl enable jenkins

5.查看狀態(tài)
[root@iZuf6fy2kg5mx828krkhcuZ qqc_data]# systemctl status jenkins

2、使用

2.1 啰嗦幾句

ps: 配置了半天也沒搞清楚怎么操作，各種選項操作太復雜了；
它的基本流程：手動在服務器執(zhí)行發(fā)布任務命令的過程，進行封裝后，可視化頁面進行一鍵批量調用；
本質上就是干了這么一件事，附加了一些用戶權限，發(fā)布日志記，異常發(fā)郵件等相關功能；
有興趣的同學去jenkins官網(wǎng)(https://www.jenkins.io/zh/doc/)學一下，我暫時學不會啊

2.2 自己實現(xiàn)簡易版發(fā)布接口

目標：在本地起一個flask 服務，寫一個發(fā)布接口
(1) 建一個表，存發(fā)布日志信息，基本信息如：用戶id,發(fā)布描述信息，服務器返回的日志等
(2)連接服務器，執(zhí)行發(fā)布命令，日志信息入庫，返回

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):
        """ 連接服務器 """
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

        # 通過ssh 私鑰登錄
        ssh.connect(hostname='47.102.138.171', username='root', key_filename=r'C:\Users\admin\.ssh\id_rsa')
        return ssh

    @property
    def command(self):
        """ 發(fā)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):
        """ 記錄發(fā)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):
        """ 執(zhí)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()}

調用路由(參數(shù)根據(jù)實際業(yè)務需求調節(jié))：
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. 測試

問題：
1、多臺服務器發(fā)布
2、用戶使用權限配置
3、實際生產過程中，通過跳板機連接到生產服務器；
4、可視化頁面操作
ps:優(yōu)化是沒完沒了的過程，有興趣的伙伴們來完善起來了啊
