jenkins安装

jenkins是通用的持续集成工具，应用很是普遍。下面开始在服务器安装jenkins，记录安装过程。

一、添加yum repos，而后安装

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key

sudo yum install jenkins

二、若是未安装java还需安装java

三、启动和中止

sudo service jenkins start
sudo service jenkins stop
sudo service jenkins restart

四、若是启动报错，一般是由于配置文件设置的jdk环境不对。修改配置文件  

vi /etc/rc.d/init.d/jenkins

找到以下类似地方：

# Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html
candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/bin/java

能够把本身本机java路径加入进来。

 

五、若是提示权限问题，能够修改默认USER或者修改文件owner，简单起见咱们直接把默认用户从jenkins换成root。

固然，安全起见，真实的线上环境不建议这么操做。

修改配置文件  /etc/sysconfig/jenkins

修改下面的参数为相应的用户，好比JENKINS_USER="root"

## Type:        string
## Default:     "jenkins"
## ServiceRestart: jenkins
#
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="jenkins"

 

六、修改相应文件或目录的权限

/var/lib/jenkins/
/var/log/jenkins/
/var/cache/jenkins/
/usr/lib/jenkins/jenkins.war
/etc/sysconfig/jenkins

chown -R root:root /var/lib/jenkins/
chown -R root:root /var/log/jenkins/
chown -R root:root /var/cache/jenkins/
chown root:root /usr/lib/jenkins/jenkins.war
chown root:root /etc/sysconfig/jenkins

 

七、重启jenkins：service jenkins restart

八、修改端口号:

vim /etc/sysconfig/jenkins

找到相似：

## Type:        integer(0:65535)
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"

直接将默认8080修改成本身指定的端口便可。

 

登录时默认初始密码地址：

/var/lib/jenkins/secrets/initialAdminPassword
