Jenkins系列之三——centos7.4+GitLab+Jenkins部署

GitLab介绍

GitLab 是一个用于仓库管理系统的开源项目，使用Git作为代码管理工具，并在此基础上搭建起来的web服务。

系统环境准备

建议：内存4G以上不然带不动

[root@hejianlai-jenkins ~]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
[root@hejianlai-jenkins ~]# uname -r

#关闭firewalld和NetWorkManager

[root@hejianlai-jenkins ~]# systemctl stop firewalld
[root@hejianlai-jenkins ~]# systemctl stop NetWorkManager

#永久关闭

[root@hejianlai-jenkins ~]# systemctl disable firewalld
[root@hejianlai-jenkins ~]# systemctl disable NetWorkManager

#关闭selinux

[root@hejianlai-jenkins ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@hejianlai-jenkins ~]# setenforce 0

#更换阿里源和下载epel源

[root@hejianlai-jenkins ~]#mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
[root@hejianlai-jenkins ~]#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@hejianlai-jenkins ~]#wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

#yum源更新，重启系统

[root@hejianlai-jenkins ~]# yum update && reboot

#安装相应工具

[root@hejianlai-jenkins ~]yum install curl policycoreutils openssh-server openssh-clients postfix -y
[root@hejianlai-jenkins ~]systemctl start postfix

#新建GitLab源

[root@hejianlai-jenkins ~]# vim /etc/yum.repos.d/gitlab-ce.repo
[gitlab-ce]

gpgkey=https://packages.gitlab.com/gpg.key
[root@hejianlai-jenkins ~]# yum makecache
[root@hejianlai-jenkins ~]# yum install -y gitlab-ce

#安装git工具

[root@hejianlai-jenkins ~]# yum install git -y

#加载配置文件并启动，时间稍长

[root@hejianlai-jenkins ~]# gitlab-ctl reconfigure

#gitlab-ctl其他命令

启动：gitlib-ctl start
关闭：gitlab-ctl stop
重启：gitlab-ctl restart
重载配置：gitlab-ctl reconfigure
查看状态：gitlab-ctl status

#查看端口保证80端口不被占用

[root@hejianlai-jenkins ~]# lsof -i:80

warning: push.default is unset; its implicit value is changing in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the current behavior after the default changes, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

GitLab上查看：

#安装JenKins

[root@hejianlai-jenkins web-demo]# sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

[root@hejianlai-jenkins web-demo]# sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
[root@hejianlai-jenkins web-demo]# yum install java jenkins –y
#JenKins默认端口为8080，因为gitlab已经占用我们需要更改。

[root@hejianlai-jenkins web-demo]# vim /etc/sysconfig/jenkins

JENKINS_PORT="8080"  ---> JENKINS_PORT="8081"

#启动JenKins

[root@hejianlai-jenkins web-demo]# /etc/init.d/jenkins start
Starting jenkins (via systemctl):                          [  OK  ]

#浏览器登录JenKins，地址：http://192.168.247.135:8081/

正在启动；

进入有个密码路径，系统上查看这个文件并把密码复制粘贴才能登录；

选择推荐安装；

创建一个管理员

开始使用jenkins

下面实现持续集成

进入主页--创建一个新任务

输入项目名称---构建一个自由风格的软件项目---确认

General--填写项目描述

源码管理--安装git插件--授权认证

ssh私钥认证我们在系统上查看粘贴进去即可。

Credentials—选择root
