CentOS7下的Django2集成部署五：Jenkins的流水线部署pipeline-job

1.Push本地的项目到GitLab

　　准备工作：由于之前在MySQL设置时禁止了root用户的远程访问，此处需要授权一个新的用户

mysql> GRANT ALL PRIVILEGES ON *.* TO 'py3web'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

#新建数据库

  mysql> CREATE DATABASE pyblog DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
  Query OK, 1 row affected (0.01 sec)

　　本地项目初始目录

　　　　

　　在GitLab上新建项目

　　　　

　　push本地项目到GitLab

admin@DESKTOP-BC8FMN2 MINGW64 /e/python
$ cd my-blog/

$ git init
Initialized empty Git repository in E:/python/my-blog/.git/

$ git remote add origin git@192.168.23.211:root/my-blog.git

$ git add .

$ git commit -m "initial code"

admin@DESKTOP-BC8FMN2 MINGW64 /e/python/my-blog (master)
$ git push -u origin master

2.创建Jenkins的pipeline-job

　　创建步骤

　　　　

　　基本设置

　　　　　　

　　　构建触发器

　　　　　　

　　流水线构建

　　　　　　

　　重新保存下设置。

　　同样的，需要将 Build Triggers里的GitLab CI Service URL http://192.168.23.211:8080/project/blog-pipeline-job 和 Secret Token 配置到GitLab的该git项目的settings-->intergrations中

　　　　　　

　　此时需要在项目中添加下Jenkinsfile，以便后面的调试

　　　　　　

　　提交后，Jenkins这边就已经自动触发了

　　　　　　

　　执行完成后可以看到流水线记录

　　　　　　

　　基本上pipeline已经就绪了

3.初步调试构建

　　给my-blog项目配置nginx的conf

[root@home-ct75211 ~]# vim /etc/nginx/conf.d/my_blog.conf

    server {
        listen       80;
        server_name  www.my-blog.cc;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            include  uwsgi_params;
            uwsgi_pass  127.0.0.1:21190;         
            uwsgi_param UWSGI_SCRIPT luffy_blog.wsgi;
            uwsgi_param UWSGI_CHDIR  /usr/share/nginx/html/my_blog;
            index  index.html index.htm;
            client_max_body_size 35m;
            #uwsgi_cache_valid 1m;
            #uwsgi_temp_file_write_size 64k;
            #uwsgi_busy_buffers_size 64k;
            #uwsgi_buffers 8 64k;
            #uwsgi_buffer_size 64k;
            #uwsgi_read_timeout 300;
            #uwsgi_send_timeout 300;
            #uwsgi_connect_timeout 300;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }


    }

[root@home-ct75211 ~]# systemctl restart nginx

　　要自动部署，后面的流水线脚本则需要重新修改下

pipeline {
    agent any
    stages{
        stage("fetch code"){
            steps {
                echo "fetch code"
                sh "pwd"
            }        
        }
        stage("unit test"){
            steps {
                echo "unit test"
                echo "${BUILD_NUMBER}"
            }        
        }
        stage("package"){
            steps {
                echo "package"
                sh 'tar czf /opt/blog-${BUILD_ID}.tar.gz ./* --exclude=./git --exclude=Jenkinsfile'
            }
            
        }
        stage('deploy'){
            steps {
                sh 'cd /var/webroot && mkdir blog-${BUILD_ID}'
                sh 'cp /opt/blog-${BUILD_ID}.tar.gz /var/webroot/blog-${BUILD_ID}'
                sh 'cd /var/webroot/blog-${BUILD_ID} && tar xf blog-${BUILD_ID}.tar.gz && rm -f blog-${BUILD_ID}.tar.gz'
                sh 'cd /var/webroot && rm -rf my_blog && ln -s /var/webroot/blog-${BUILD_ID} /usr/share/nginx/html/my_blog'
            }
            
        }
        stage('finished'){
            steps {
                echo "finished"
                sh "date +%F"
            }
            
        }
    }
}

　　提交后，Jenkins那边的显示为

　　　　

　　　　

　　可以看到触发的脚本事件正常运行了，访问下看下

[root@home-ct75211 my_blog]# elinks http://www.my-blog.cc --dump
   Internal Server Error
# 看下uwsgi的日志

[root@home-ct75211 my_blog]# tailf /var/log/uwsgi21190.log 
added /root/py3web/lib/python3.7/site-packages/ to pythonpath.

　　因为虚拟环境的pip里只装了Django，但项目中还有用到了其他模块，此处需要同步下pip环境。其实到这里，pipeline的部署已经基本完结了，后面的基本就属于Django项目的环境问题了
