在centos7上安裝Jenkins

安裝

添加yum repos，然后安裝

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key sudo yum install jenkins

如果沒有java的話要安裝java

sudo yum install java

啟動和停止

sudo service jenkins start/stop/restart sudo chkconfig jenkins on

jenkins的默認設置

• Jenkins會隨系統(tǒng)啟動而啟動。詳情參照/etc/init.d/jenkins
• Jenkins會創(chuàng)建一個用戶叫做jenkins, 如果你修改了user，則要修修改所屬者：/var/log/jenkins,/var/lib/jenkins,/var/cache/jenkins
• 如果遇到問題，查看日志/var/log/jenkins/jenkins.log
• 配置文件/etc/sysconfig/jenkins
• 默認啟用8080

打開和關閉防火墻

firewall-cmd --zone=public --add-port=8080/tcp --permanent firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --reload firewall-cmd --list-all

關于centos上的java

Jenkins不支持在centos的默認的jdk上工作。如果如下所示，則需要remove：

java -version java version "1.5.0" gij (GNU libgcj) version 4.4.6 20110731 (Red Hat 4.4.6-3)

為了正確使用Jenkins：

yum remove java

然后可以安裝openjdk

yum install java-1.7.0-openjdk

正確如下：

java -version java version "1.7.0_79" OpenJDK Runtime Environment (rhel-2.5.5.1.el6_6-x86_64 u79-b14) OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

配置端口

修改/etc/sysconfig/jenkins:

JENKINS_PORT="8080"

配置java路徑

直接啟動：

sudo service jenkins start

但是發(fā)現(xiàn)啟動失敗，于是需要配置java位置：

vi /etc/init.d/jenkins

在啟動加入本機的java：

[root@iZ94xvn71eeZ ~]# vim /etc/init.d/jenkins # Set up environment accordingly to the configuration settings [ -n "$JENKINS_HOME" ] || { echo "JENKINS_HOME not configured in $JENKINS_CONFIG";if [ "$1" = "stop" ]; then exit 0;else exit 6; fi; } [ -d "$JENKINS_HOME" ] || { echo "JENKINS_HOME directory does not exist: $JENKINS_HOME";if [ "$1" = "stop" ]; then exit 0;else exit 1; fi; }# 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 /usr/java/jdk1.7.0_80/bin/java "

上述最后一行是我添加的。

重啟，可以正常運行了。

啟動

瀏覽器輸入ip和端口訪問，第一個頁面是正在啟動，啟動結束后會讓輸入一串密碼，然后進入插件安裝界面，選擇默認，這時候會報錯：
An error occurred during installation: Forbidden

解決辦法：
I "fixed it" by restarting Jenkins http://localhost:8080/restart。即重啟就可以繼續(xù)了。
