基於gitlab和jenkins的自動化部署例項
阿新 • • 發佈：2019-02-19
gitlab+jenkins服務簡述：
GitLab是一個程式碼倉庫，用來管理程式碼。Jenkins是一個自動化伺服器，可以執行各種自動化構建、測試或部署任務。
所以這兩者結合起來，就可以實現開發者提交程式碼到GitLab，Jenkins以一定頻率自動執行測試、構建和部署的任務，
幫組開發團隊更高效的整合和釋出程式碼。實驗環境：
紅帽7.3版本虛擬機器gitlab的安裝配置,官網給的配置最低要求為4G，使用虛擬機器配置的話結合物理機的配置要求分配記憶體：
[root@test1 ~]# yum install curl policycoreutils openssh-server openssh-clients postfix 安裝依賴性 
安裝過程比較慢因為是跟我們分配記憶體大小相關，安裝成功會出來gitlab的圖案：
[root@test1 ~]# vim /etc/gitlab/gitlab.rb 編輯配置檔案寫入當前主機IP，修改gitlab倉庫路徑 
[root@test1 ~]# gitlab-ctl reconfigure 初始化gitlab
[root@test1 ~]# gitlab-ctl restart 過載服務
在網頁訪問輸入密碼大於八位即可：

我們可以建立一個新工程：
建立工程成功：
配置免密連線：
[root@foundation38 Desktop]# systemctl restart httpd 重啟httpd服務
[root@foundation38 Desktop]# cd
[root@foundation38 
配置gitlab的免密連線：
[root@foundation38 .ssh]# git clone [email protected]:root/demo.git 進行克隆

在gitlab介面可以看到實時資料：
重新開啟一臺虛擬機器配置jenkins：
[root@localhost ~]# ls
[root@localhost ~]# route -n 檢視閘道器
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.25.0.0 0.0.0.0 255.255.0.0 U 100 0 0 eth0
[root@localhost ~]# ip route add default via 172.25.38.250 新增閘道器
[root@localhost ~]# route -n 檢視閘道器

[root@localhost ~]# vim /etc/resolv.conf 配置dns
[root@localhost ~]# cat /etc/resolv.conf
nameserver 114.114.114.114
[root@foundation38 Desktop]# iptables -t nat -I POSTROUTING -s 172.25.38.0/24 -j MASQUERADE 在真機新增策略
[root@localhost ~]# ping www.baidu.com 保證虛擬機器可以ping通百度（上網即可）
jenkins的安裝配置：
[root@localhost ~]# ls
jdk-8u171-linux-x64.rpm jenkins-2.121.1-1.1.noarch.rpm
[root@localhost ~]# yum install * -y
[root@localhost ~]# systemctl status jenkins

在網頁訪問jenkins：
根據提示在虛擬機器獲取初始化密碼：
[root@localhost ~]# cat /var/lib/jenkins/secrets/initialAdminPassword
