• 基于Jenkins实现可腹部回滚的cicd平台


    • Jenkins :是一个开源的实现持续集成的工具,可以实施监控持续集成过程中所存在的问题,提供详细的日志文件和提醒功能,还能用图表的形式直观的展示出项目构建的趋势和稳定性
    • maven:只有在Java项目时才会使用,帮助实现Java项目的打包
    • ansible:自动化运维工具,实现批量系统配置,批量程序部署,批量运行命令等

    基于Jenkins+git+docker 发布Java项目

    192.168.200.10 git Git/Docker registry
    192.168.200.20 jenkins jenkins
    192.168.200.14 docker docker

    [root@docker ~]# setenforce 0
    setenforce: SELinux is disabled
    [root@docker ~]# iptables -F
    [root@docker ~]# systemctl stop firewalld

    配置Git模拟开发提交

    [root@Git ~]# rpm -q git

    [root@Git ~]# useradd git
    [root@Git ~]# passwd git  #设置密码123456
    
    #配置jenkins主机上免交互拉取Git仓库
    [root@jenkins ~]# ssh-keygen
    [root@jenkins ~]# ssh-copy-id git@192.168.200.14
    [root@jenkins ~]# ssh git@192.168.200.20  #测试git
    [git@Git ~]$ exit
    
    #在git服务器上创建probe仓库
