使用jenkins搭建gitlab持续集成CI和持续部署CD

1.gitlab安装

gitlab的安装就不说了

2.java环境

由于之前就已经安装了java环境，所以就也不说了

3.安装jenkins

命令安装jenkins

wget -q -O - https://pkg.jenkins.io/debian/jenkins-ci.org.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins

如果出现启动失败，则可能需要修改端口

配置文件在 /etc/default/jenkins中，
- NAME 默认用户名为jenkins
- HTTP_PORT 默认8080 可以更改端口号等相关配置，
密码在 /var/lib/jenkins/secrets/initialAdminPassword中，如果没有权限访问可以修改文件夹权限。

修改完后重启启动jenkins

sudo service jenkins start

如果出现启动失败，使用journalctl -xe显示

-- Unit jenkins.service has begun starting up.
Aug 06 02:44:37 onehour jenkins[22830]: ERROR: No Java executable found in current PATH: /bin:/usr/bin:/sbin:/usr/sbin
Aug 06 02:44:37 onehour jenkins[22830]: If you actually have java installed on the system make sure the executable is in the aforementioned path and that 'type -p java' returns the java executable path
Aug 06 02:44:37 onehour systemd[1]: jenkins.service: Control process exited, code=exited status=1
Aug 06 02:44:37 onehour systemd[1]: jenkins.service: Failed with result 'exit-code'.
Aug 06 02:44:37 onehour systemd[1]: Failed to start LSB: Start Jenkins at boot time.

需要将java执行文件添加软连接到/bin:/usr/bin:/sbin:/usr/sbin其中一个目录下

sudo ln -s /usr/java/jdk1.8/bin/java java

使用type -p java检测
