在CentOS 7上安裝Jenkins

安裝

添加yum repos，然後安裝

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.keysudo 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會隨系統啟動而啟動。詳情參照/etc/init.d/jenkins

• Jenkins會創建一個用戶叫做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，查看日誌/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 --permanentfirewall-cmd --zone=public --add-service=http --permanentfirewall-cmd --reload

firewall-cmd --list-all

關於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 -versionjava 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

然後可以安裝openjdk

yum install java-1.7.0-openjdk

正確如下：

java -versionjava 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

但是發現啟動失敗，於是需要配置java位置：

vi /etc/init.d/jenkins

在啟動加入本機的java：

[[email protected] ~]# 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.htmlcandidates="
/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
"

上述最後一行是我添加的。

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，啟動結束後會讓輸入一串密碼，然後進入插件安裝界面，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。即重啟就可以繼續了。
