gitlab+jenkins自动化部署环境搭建

环境说明

系统 主机 IP 安装软件
CentOS 7 study-1 192.168.100.51 gitlab、git
CentOS 7 study-2 192.168.100.52 jdk、maven、jenkins、git
CentOS 7 study-3 192.168.100.53 tomcat、mysql、jenkins、git

所有系统的selinux和iptables都已经关闭,同时需要做好时间同步,机器的hosts文件如下:

192.168.100.51 study-1 gitlab.study.com
192.168.100.52 study-2
192.168.100.53 study-3

下面还需要在study-1机器上生成的公钥和私钥复制到study-2和study-3主机上。

[root@study-1 ~]# ssh-keygen 
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory ‘/root/.ssh‘.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
f0:02:05:f7:5c:9c:66:d2:25:42:42:a4:11:dc:27:92 root@study-1
The key‘s randomart image is:

gitlab主机配置

下载

下载地址:https://mirror.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

安装

[root@study-1 ~]# yum install -y gitlab-ce-8.16.9-ce.0.el7.x86_64.rpm

配置

安装后修改配置文件中的如下内容:

[root@study-1 ~]# vim /etc/gitlab/gitlab.rb
......
external_url ‘http://gitlab.study.com‘
......
[root@study-1 ~]# gitlab-ctl reconfigure
[root@study-1 ~]# gitlab-ctl start

启动后需要登录:http://gitlab.study.com 然后去设置用户root的密码这里不做介绍。之后需要进行密钥的配置,这个比较简单就不错介绍

测试程序配置

这里的测试代码是用的如下的内容:https://git.oschina.net/zchuanzhao/jeesns.git
下面是在gitlab克隆测试的代码:

安装插件
点击左侧的“系统管理”----"管理插件"------“已安装”---查找需要安装的插件:git-client/scm-api/git/publish over SSH//ssh

jenkins设置

密钥的配置

[root@study-2 opt]# cp /root/.ssh/* /var/lib/jenkins/.ssh/
[root@study-2 opt]# chown -R jenkins.jenkins /var/lib/jenkins/.ssh/

Global Tool Configuration 配置
点击左侧的“系统管理”----"Global Tool Configuration"
下面是jdk和git的配置:

Credentials 配置
点击左侧“Credentials”-->“System”-->在“Global credentials (unrestricted)”选择“Add Credentials”-->写上登录gitlab上的帐号密码。

系统设置
配置gitlab主机:

jenkins的访问地址,自动生成可以不用配置:

Configure Global Security 配置
SSH Server 端口的修改,这里使用的是默认端口:

安装排错

构建时控制台报错如下:

Host key verification failed.
lost connection
Build step ‘Execute shell‘ marked build as failure
SSH: Current build result is [FAILURE], not going to run.
Finished: FAILURE

原因:这个是由于ssh密钥配置的问题,虽然我们在系统配置中配置了私钥但是还是不行。原先我是用root运行jenkins,而rpm包是用普通用户运行。所以密钥需要拷贝至jenkins的家目录中及:/var/lib/jenkins/.ssh/中才能使用。

构建项目

创建
点击左侧的“新建”然后如下:

构建
点击“增加构建步骤”-->选择“Execute shell”:

点击“增加构建步骤”-->选择“Invoke top-level Maven targets”:

配置了上面的信息后,maven会将打包的war包放在下面的这个目录中:
/var/lib/jenkins/jobs/study/workspace/target/
/var/lib/jenkins/:jenkins的工作目录
jobs/study/:jenkins管理study项目的目录
workspace:表示maven等插件的工作目录

上面图片来自:http://www.cnblogs.com/horizonli/p/5332515.html 。之后就是保存了。我们还可以在上面中继续添加server,添加server之前需要提前做好设置。

执行构建的项目
下面就是选择刚才创建的项目并执行“立即构建”。

技术分享

构建后我们还可以在“Console Output”中查看构建执行的状态。

下面是远程主机执行的脚本,没有做过多的判断只能能够让其运行起来就行了。

[root@study-3 jeesns]# cat /opt/deploy/deploy.sh 
#!/bin/bash

tomcatPid=`ps aux |grep tomcat |grep -v grep|awk ‘{print $2}‘`
kill $tomcatPid
sleep 5
rm -rf /usr/local/tomcat/webapps/jeesns*
cp /opt/deploy/jeesns/jeesns.war /usr/local/tomcat/webapps/
/usr/local/tomcat/bin/catalina.sh start
echo ‘部署完毕‘
