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
打開和關閉防火牆
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 -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：
[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.

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。即重啟就可以繼續了。
