ContenOS 安装配置 rpm 版本 Jenkins

软件准备：

jenkins-2.7.4-1.1.noarch.rpm　　　　　　java环境

安装jenkins：

[root@localhost modules]# rpm -ih jenkins-2.7.4-1.1.noarch.rpm

jenkins 常用命令：

service jenkins start/stop/restart

chkconfig jenkins on

jenkins的目录结构：

/usr/lib/jenkins/jenkins.war     WAR包

/etc/sysconfig/jenkins       　　 配置文件

/var/lib/jenkins/        　　　　   默认的JENKINS_HOME目录

/var/log/jenkins/jenkins.log      Jenkins日志文件

启动jekins：

[root@localhost jenkins]# service jenkins start
Starting Jenkins bash: /usr/bin/java: 没有那个文件或目录
[失败]

出现此异常说明没有找到 java 目录下的 bin 目录，解压不了 jenkins.war 。

解决方案：

[root@localhost bin]# vim /etc/init.d/jenkins

# Search usable Java. We do this because various reports indicated
# that /usr/bin/java may not always point to Java >= 1.6
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html

for candidate in $candidates
do

JENKINS_JAVA_CMD="$candidate"
done

JAVA_CMD="$JENKINS_JAVA_CMD $JENKINS_JAVA_OPTIONS -DJENKINS_HOME=$JENKINS_HOME -jar $JENKINS_WAR"

带色文字为我的 java 目录，脚本含义就是查找 java 目录，解压jenkins.war包。

修改jenkins端口：

vim /etc/sysconfig/jenkins
JENKINS_PORT="8888"

防火墙开启8888端口：

[root@localhost modules]# vim /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter

:FORWARD ACCEPT [0:0]

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

再次启动jenkins：

[root@localhost modules]# service jenkins start

效果图：

出现此提示说明，启动成功！因为是第一次安装，所以得输入默认密码，默认密码在红框标注的位置。

查看默认密码将密码粘贴到文本框中：

[root@localhost secrets]# cat /var/lib/jenkins/secrets/initialAdminPassword
