jenkins打包发布前端项目

node项目构建

    1.把npm变成cnpm

    

    2.使用cnpm进行构建打包

       sh  "cd /var/lib/jenkins/workspace/sdc-h5"
       sh  "cnpm config set strict-ssl false"
       sh  "cnpm install node-sass --unsafe-perm --save-dev"
       sh  "cnpm install"
       sh  "cnpm run build:sit"

 ansible安装配置

       1.配置免密登录 在ansible主机上使用普通用户创建公私钥即可,不一定要使用管理员用户 

         1.[jenkins@localhost ~]$ ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
         2.[jenkins@localhost ~]$ ssh-copy-id -i .ssh/id_rsa.pub admin@192.168.30.98

          

        3.ansible建立ssh免密的时候必须选用合适的用户 服务端主机上和客户端主机上必须存在同样的用户才行

           ansible主机上存在jenkins普通用户 但是远程主机上没有jenkins用户，执行ansible命令的时候是以jenkins用户远程连接的 所以会出现连接异常

         

       4.在ansible主机上从jenkins用户切换到admin用户,然后重新生成公私密钥即可

       5.在执行ansible命令的时候指定远程连接用户

          ansible webservers --user=admin -m ping

          

发布项目流程

    ansible webservers --user=admin -m copy -a "src=/var/lib/jenkins/workspace/sdc-h5/dist/* dest=/home/admin/testh5/"
    copy模块用于将本地或远程机器上的文件拷贝到远程主机上
    拷贝前备份  backup=yes
    src是目录时
        源目录以/结尾,只拷贝了目录下的内容
        源目录未以/结尾,直接将src目录本身拷贝到目的地
    src和dest都是文件,若dest的文件的父目录不存在将报错

   

 Pipeline依次执行指令

         1.获取命令执行是否成功             excuteCode = sh(script: "<shell command>", returnStatus: true)    

         2.获取命令执行的输出内容          result = sh(script: "<shell command>", returnStdout: true)

              }
           }
      }

 如果其中一条命令执行失败,后面的指令就会中断执行.

错误排查

  1. name cannot start with an underscore; name can only contain URL-friendly characters

     原因分析：通过cnpm命令安装模块时，会同时生成带下划线的文件（eg: _jquery@3.4.1@jquery)，不符合命名规范（根据报错提示）

     1.安装模块时用npm，非cnpm

     2.先通过npm init初始化目录，生成包管理文件package.json，再安装模块（npm/cnpm）

  2.如何指定`package.json`的npm的路径

     cnpm run build:sit -config=/var/lib/jenkins/workspace/netcehui-h52/h5-new/package.json
