jenkins脚本式自动部署

一.介绍

比起jenkins声明式流水线，脚本式简单很多而且相对用得比较多。
为了理解jenkins的工作原理，需先在本地完全部署运行过一次项目后，才能用在jenkins上。
所以本节示例先用java项目在本地运行后，再用脚本进行CI/CD发版部署。
jenkins和gitlab在之前的文章上已经有安装详情：
jenkins和gitlab安装：https://www.yj-example.cn/?p=1871

二.手动部署微服务（本地）

那么我们以java微服务为案例先在本地经行部署。
项目说明：本项目使用开源的pig微服务开发框架pig4为案例进行部署
项目地址：https://www.yuque.com/pig4cloud/pig/gg3ndm
前端代码：https://gitee.com/log4j/pig-ui
后端代码：https://gitee.com/log4j/pig
项目介绍：前端使用HTML、nodejs编写，后端使用：java语言编写，数据库使用：redis、ysql，项目使用nacos进行统一管理
服务器：jenkins服务器（编译）4C8G、gitlab服务器、mysql+redis+应用服务器（由于示例都放一起了）4c8G
java项目需使用maven进行编译打包，前端项目需要使用node进行打包

1.服务器安装配置maven

配置maven环境apache-maven-3.6.2
所有服务器关防火墙、selinux：

systemctl stop firewalld
vi /etc/selinux/config
SELINUX=disable 

reboot

下载安装maven包（需要在jenkins服务器和应用服务器安装）：

[root@jenkins ~]# cd /export/soft/
[root@jenkins soft]# wget https://dlcdn.apache.org/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz --no-check-certificate
[root@jenkins soft]# tar xf apache-maven-3.6.3-bin.tar.gz 
[root@jenkins soft]# mv apache-maven-3.6.3 /usr/local/apache-maven
[root@jenkins soft]#  vi /etc/profile
# 最后一行添加
export MAVEN_HOME=/usr/local/apache-maven
export PATH=$MAVEN_HOME/bin:$PATH
# 生效环境变量
[root@jenkins soft]# source /etc/profile

#验证：
[root@jenkins soft]# mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

2.后端编译

可以在jenkins服务器上编译

[root@jenkins ~]# mkdir pig
[root@jenkins ~]# cd pig/

下载后端代码进行编译—-代码准备

https://github.com/pig-mesh/pig
[root@jenkins pig]##将代码上传至本目录
[root@jenkins pig]# ls
pig-master.zip
[root@jenkins pig]# unzip pig-master.zip 
[root@jenkins pig]# cd pig-master/

编译成jar包

[root@jenkins pig-master]# mvn clean install -Dmaven.skip.test=true

3.安装数据库mysql

mysql和redis都安装在应用服务器上
二进制安装：
[root@localhost ~]# hostnamectl set-hostname mysql && bash
#版本要求5.7+
[root@k8s-mysql ~]# cd /usr/local/
#上传下载好的mysql5.7.26的安装包到服务器

[root@k8s-mysql local]# tar xf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz 
[root@k8s-mysql local]# ln -s mysql-5.7.26-linux-glibc2.12-x86_64 mysql57
[root@k8s-mysql local]# vim /etc/profile
......
export PATH=/usr/local/mysql57/bin:$PATH

[root@k8s-mysql local]# source /etc/profile
#注意：此处配置文件lower_case_table_names = 1为不区分大小写配置（可根据实际情况修改）
[root@k8s-mysql local]# vim  /etc/my.cnf 
[mysqld]
user=mysql
port=3306
basedir=/usr/local/mysql57
datadir=/data/mysql/data_3306
server_id=6
socket=/tmp/mysql.sock
lower_case_table_names = 1
[mysql]
socket=/tmp/mysql.sock


[root@k8s-mysql local]# useradd mysql
[root@k8s-mysql local]# mkdir /data
[root@k8s-mysql local]# mkdir -p /data/mysql/data_3306                 #数据路径
[root@k8s-mysql local]# mkdir -p /data/mysql/binlog_3306               #binlog日志路径
[root@k8s-mysql local]# chown -R mysql.mysql /usr/local/mysql57
[root@k8s-mysql local]# chown -R mysql.mysql /data
[root@k8s-mysql local]# yum install libaio-devel -y
[root@k8s-mysql local]# cd /data/mysql/data_3306/
#忽略警告。。。。。。
[root@k8s-mysql local]# mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql57 --datadir=/data/mysql/data_3306
[root@k8s-mysql local]# cd /usr/local/mysql57/support-files/
[root@k8s-mysql support-files]# ls
magic  mysqld_multi.server  mysql-log-rotate  mysql.server
[root@k8s-mysql support-files]# cp mysql.server /etc/init.d/mysqld
[root@k8s-mysql support-files]# chkconfig --add mysqld
[root@k8s-mysql support-files]# systemctl start mysqld
[root@k8s-mysql support-files]# systemctl enable mysqld
mysqld.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysqld on
[root@k8s-node1 support-files]# mysql
mysql>

mysql操作(系统数据库中写的默认账号密码均为root)
创建账号密码 root root

mysqladmin -u root password "root"

4.安装数据库redis

[root@mysql ~]# yum install redis -y
[root@mysql ~]# vim /etc/redis.conf 
......
bind 192.168.1.123
# bind 127.0.0.1  #注释这行
[root@mysql ~]# systemctl restart redis
[root@mysql ~]# systemctl enable redis

5.导入微服务系统数据

在mysql机器上创建存放数据的目录

[root@mysql ~]# mkdir pigdb

将代码中SQL数据推送至mysql服务器pigdb目录中

[root@jenkins pig-master]# scp -rp db/* root@192.168.1.123:/root/pigdb/

在mysql服务器导入数据

[root@mysql ~]# mysql -uroot -p123456
mysql> source /root/pigdb/pig_codegen.sql;
mysql> source /root/pigdb/pig_config.sql;
mysql> source /root/pigdb/pig_job.sql;
mysql> source /root/pigdb/pig.sql;
mysql> show databases;
+--------------------+
| Database           |

| pig_job            |
| sys                |
+--------------------+
8 rows in set (0.00 sec)

6.启动nacos

配置host解析
现在在jenkins和应用服务器上加上解析，后面能用到。

[root@jenkins ~]# cat /etc/hosts
192.168.1.123   pig-mysql
192.168.1.123   pig-redis
127.0.0.1   pig-gateway
127.0.0.1   pig-register
127.0.0.1   pig-sentinel
127.0.0.1   pig-monitor
127.0.0.1   pig-job

启动nacos

[root@jenkins ~]# cd /root/pig/pig-master/pig-register/target
[root@jenkins target]# nohup java -jar pig-register.jar &
[root@jenkins target]# tail -f nohup.out                 #注意不要报错哦

#访问nacos   IP:8848/nacos    账号密码都是nacos

7.启动pig-upms微服务

注意：一定要按照下面笔记顺序启动
启动pig-upms

[root@jenkins ~]# cd /root/pig/pig-master/pig-upms/pig-upms-biz/target
[root@jenkins target]# nohup java -jar pig-upms-biz.jar &

查看日志没问题再进行下一步

[root@jenkins target]# tail -f nohup.out 
2022-02-25 16:56:13.872  INFO 24266 --- [           main] io.undertow                              : starting server: Undertow - 2.2.14.Final

8.启动pig-auth

[root@jenkins ~]# cd pig/pig-master/pig-auth/target/
[root@jenkins target]# nohup java -jar pig-auth.jar & 
2022-02-25 17:10:36.793  INFO 24782 --- [           main] o.s.b.a.e.web.EndpointLinksResolver      : Exposing 20 endpoint(s) beneath base path '/actuator'

9.启动pig-gateway

[root@jenkins ~]# cd pig/pig-master/pig-gateway/target/
[root@jenkins target]# nohup java -jar pig-gateway.jar &
[root@jenkins target]# tail -f nohup.out 
2022-02-25 17:12:28.427  INFO 24968 --- [           main] o.s.c.g.r.RouteDefinitionRouteLocator    : Loaded RoutePredicateFactory [Weight]

三个微服务部署完后可以在nacos上找到服务列表上，查看有没被注册
如图所示，三个服务都是正常的：

10.前端项目部署

所有的前端代码均需使用node进行编译打包
代码获取：https://github.com/pig-mesh/pig-ui
将下载的代码上传到服务器：

[root@jenkins ~]# mkdir pig-web && cd pig-web
[root@jenkins pig-web]# ls
pig-ui-master.zip
[root@jenkins pig-web]# unzip pig-ui-master.zip

配置nodejs环境

[root@jenkins ~]# cd /export/soft/
[root@jenkins soft]# wget https://nodejs.org/dist/v12.18.1/node-v12.18.1-linux-x64.tar.xz
[root@jenkins soft]# tar xf node-v12.18.1-linux-x64.tar.xz 
[root@jenkins soft]# mv node-v12.18.1-linux-x64 /usr/local/node
[root@jenkins soft]# vi /etc/profile
......最后加......
export PATH=$PATH:/usr/local/node/bin

#使环境变量失效
[root@kjenkins ~]# source /etc/profile
[root@jenkins ~]# cd /usr/local/node/bin
#查看版本（当前位置生效）
[root@jenkins bin]# ./node -v
v12.18.1

#配软连接：
相当于全局变量，在任何文件夹都能查看版本信息
ln -s /usr/local/node/bin/node /usr/local/bin/
ln -s /usr/local/node/bin/npm /usr/local/bin/

#测试全局是否生效
[root@jenkins bin]# cd
[root@jenkins ~]# node -v
v12.18.1

编译打包前端代码

[root@jenkins ~]# cd /root/pig-web/pig-ui-master
[root@jenkins pig-ui-master]# npm install -g yarn
[root@jenkins pig-ui-master]# yarn install
[root@jenkins pig-ui-master]# yarn run build
[root@jenkins pig-ui-master]# ls
babel.config.js  dist  docker  jsconfig.json  LICENSE  node_modules  package.json  public  README.md  src  vue.config.js  yarn.lock

11.配置nginx

简易安装一下：
先配置一个yum源

vim /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

yum install -y yum-utils
yum-config-manager --enable nginx-mainline
yum install -y nginx


[root@jenkins pig-ui-master]# yum install nginx -y
[root@jenkins pig-ui-master]# cd /etc/nginx/conf.d/
[root@jenkins conf.d]# rm -f default.conf 
[root@jenkins conf.d]# vim laoyan.com.conf
server {
  listen 80;
    gzip on;
    gzip_static on;     # 需要http_gzip_static_module 模块
    gzip_min_length 1k;
    gzip_comp_level 4;
    gzip_proxied any;
    gzip_types text/plain text/xml text/css;
    gzip_vary on;
    gzip_disable "MSIE [1-6]\.(?!.*SV1)";
  location / {
        root /root/pig-web/pig-ui-master/dist;
    index index.html;
    }
  # 注意维护新增微服务，gateway 路由前缀
    location ~* ^/(code|act|auth|admin|gen|monitor|tx|job|damon|pay|mp) {
        proxy_pass http://pig-gateway:9999;
        proxy_set_header   Host              $host;
    proxy_set_header   X-Forwarded-Proto $scheme;
    add_header Cache-Control no-store;
    proxy_connect_timeout 15s;
        proxy_send_timeout 15s;
        proxy_read_timeout 15s;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto http;
    }
}

修改权限，权限问题有可能会403，先改下用户为root

[root@jenkins target]# vim /etc/nginx/nginx.conf
user  root;

启动nginx：

[root@jenkins conf.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@jenkins conf.d]# systemctl start nginx
[root@jenkins conf.d]# systemctl enable nginx
[root@jenkins conf.d]# nginx -s reload

直接在部署服务器上IP地址访问：如果验证码不显示：

[root@mysql pigdb]# vim /etc/redis.conf 
#注释掉下面这一行
# bind 127.0.0.1

前端输入IP进行访问

登录正常，整个项目就部署好了

三.jenkins脚本自动部署（本地）

承接上面的类容，发现手动部署比较麻烦。
传统手动上线存在的缺点
1、全程运维进行，占用大量时间。
2、如果节点多，上线速度慢。
3、人为失误多，目录管理混乱。
4、回滚不及时，或者难以回退。
5、满足不了系统可靠性9999的要求

1.Gitlab服务器设置

由于示例，现在gialab服务器上创建2个前后端项目
创建两个项目后端pig-java，前端pig-web

在Gitlab服务器上配置hosts解析

[root@gitlab ~]# vim /etc/hosts
........
192.168.1.100 gitlab.laoyan.com

配置公钥至Gitlab服务器

[root@gitlab ~]#  ssh-keygen    #一路回车
[root@gitlab ~]# cat ~/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCcj7SZW2OUiHYrggUE6P5gdPMxikKwva54rnTpWPcRZA4z3CjvnFOpitIVZXqLlpz53BqWYOcdPDMTRSNDDCLX2kGPCqNUcVHjzze8wgw7JC0fgY3lNiV/Lmhug9f7P4yV3q/lbZTFBDwAnEoftSCkZwgW1gQOBE3YbElJ5kYBswQ5rWstkU3mRKFnRrZLLd8aTDYWVhcyIPrXUTF4zcGhuP4kl5bZrz2o1r+FVkqsF5flqMhHtFFpaLKIGFEWYLvoiZDSFfv65hIBrEP76m04PWde3se/2S84j1jKi2ETV6obYuNho09bkvTQCHQhFs7Q0Ics4l5ORZhuf7eFKYb1 root@gitlab

2.Jenkins集成Gitlab

将jenkins服务器的公钥放到gitlub上面

[root@jenkins ~]# ssh-keygen 
[root@jenkins ~]# cat ~/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDTuEBgv0vLeCRn90KkYvGSI3ss+1ntwbiZpLly86xYGxYcsnNpRp+t6VUbk2PXN2ql/H+ceOha5lu/qadb/eyNxlh6pE1/hmG30sTEWb0QMoc7dq3XStAERZZmyjG43Tk/a2itrVNJB1Jh14c09+NnHxR7tz8Dq49YCdRnu6xxVYH4U+TloEL8Luxto5nFM7dht7Gfrf+Zop4ItF5DJyi7NJ5N3ICqxQM9In2wttcK0H5PuG7gwYopTATNU3SmHeqVP+jmF69GDt8gd1D5geVl3JQHMMtn72uut8ESRTuUzxpzf9hVrx3s2U8q+myy55/y86Oa7SXi6leBCAKe4k8D root@jenkins

jenkins服务器上配置host解析

[root@jenkins ~]# vim /etc/hosts
........
192.168.1.100 gitlab.laoyan.com
查看Jenkins私钥
[root@jenkins ~]# cat ~/.ssh/id_rsa

在Jenkins上面添加凭据

3.创建测试脚本

创建一个test-Java的项目

选择脚本输出测试

echo "123" >> 123.txt
sleep 5

点击立即构建—–>查看结果

在Jenkins目录中查看项目所在路径

[root@jenkins ~]# cd .jenkins/workspace/
[root@jenkins workspace]# ls
test-java
[root@jenkins workspace]# cd test-java/
[root@jenkins test-java]# ls
123.txt
[root@jenkins test-java]# cat 123.txt 
123
[root@jenkins test-java]# pwd
/root/.jenkins/workspace/test-java

4.脚本式自动化发布

jenkins需要安装基本插件Git Parameter、GitLab、Blue Ocean Core JS、Blue Ocean
加速设置：设置——->插件管理———>高级
国内加速源： https://mirror.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

5.配置nacos注册中心的发布

由于我安装Jenkins版本的问题，我需要停掉Jenkins再进行启动。。

[root@jenkins test-java]# ps aux |grep java
root       1554  8.1  6.9 3806448 461724 pts/0  Tl   14:00   5:57 java -jar jenkins.war --httpPort=28088
[root@jenkins test-java]# kill -9 1554
[root@jenkins soft]# java -jar jenkins.war

创建一个项目名称为pig-register的项目

添加Gitlab代码仓库地址

脚本启动方式

[root@jenkins ~]# mkdir pig-jenkins-sh && cd pig-jenkins-sh
[root@jenkins pig-jenkins-sh]# vim pig-register.sh
[root@jenkins pig-jenkins-sh]# cat pig-register.sh 
[root@jenkins pig-jenkins-sh]# cat pig-register.sh 
#!/bin/bash
BUILD_ID=DONTKILLME
qi=`date +'%Y%m%d%H%M'`
node=192.168.0.124  #设置应用服务器主机IP
project=pig-register #项目名称,为gitlab上项目名称，最好不要改别的，代码冲突
address=/opt/$project  #目标端代码仓库位置，演示设置/opt为代码仓库位置，实际按需设置
runningpath=/www/wwwroot/$project  #程序运行路径，目标仓库代码会链接到运行项目路径上

#cd /root/.jenkins/workspace/$project 
#mvn clean install -Dmaven.skip.test=true  #编译代码

tar -zcvf /opt/$project-$qi.tar.gz  -C /root/.jenkins/workspace $project
ssh root@$node "mkdir -p  $address" #创建目标仓库目录
scp /opt/$project-$qi.tar.gz root@$node:$address  #把编译后压缩包发送到目标应用主机的代码仓库上
rm -rf  /opt/$project-$qi.tar.gz   #清理压缩包
ssh root@$node "tar -zxf $address/$project-$qi.tar.gz -C $address;mkdir -p  $address/$project$qi" #解压代码到目标仓库
ssh root@$node "mv $address/$project  $address/$project$qi; ln -snf $address/$project$qi/$project/ $runningpath"  #链接代码目录到程序运行目录，设置/www/wwwroot/pig-register为运行目录
ssh root@$node "ps -ef |grep $project.jar |cut -c 9-15 |head -n1 |xargs kill -9" #杀死旧进程
ssh root@$node "ls -t $address |awk 'NR>3' |xargs rm -rf"  #为了节省空间,保留最新3个版本的文件（根据需求）
ssh root@$node "find $address -type d -maxdepth 1 | grep '$address/' | sort -nr |awk 'NR>3' | xargs rm -rf" #保留最新3个目录
ssh root@$node "cd $runningpath/$project/target;nohup java -jar $project.jar &" #运行新进程


Jenkins脚本配置路径
sh +x /root/pig-jenkins-sh/pig-register.sh

Jenkins点击构建进行项目构建

6.其它微服务构建的发布

和上面基本差不多，改下项目名称和仓库位置就行了

7.前端项目构建

脚本：

cd $WORKSPACE/ && yarn install && yarn run build  #编译
cp -rp dist/* /root/pig-web/pig-ui-master/dist/   #复制编译后的文件到nginx的访问目录（根据自己的设置）
nginx -s reload

#重启nginx

8.分支构建

安装jenkins插件：List Git branches
如优化之前的pig-gateway

将其它的分支按照上面的方式修改下
