Ubuntu安装Jenkins并配置改装

安装包

wget http://mirrors.jenkins-ci.org/debian-stable/jenkins_2.277.3_all.deb

按照官方提示安装

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -

向文件/etc/apt/sources.list中加入如下行

deb https://pkg.jenkins.io/debian-stable binary/

执行升级安装

 

安装完成后 find / -name jenkins 查看jenkins默认安装目录

1、配置文件：/etc/default/jenkins

2、启动脚本：/etc/init.d/jenkins

3、监听端口：8080

4、war包位置：/usr/lib/jenkins/jenkins.war

5、缓存目录：/var/cache/jenkins

6、文档目录：/usr/share/doc/jenkins

7、日志文件：/var/log/jenkins/

目录修改配置如下：

# mkdir /opt/jenkins

# mkdir /opt/jenkins/logs && mkdir /opt/jenkins/plugins && mkdir /opt/jenkins/conf && mkdir /opt/jenkins/lib && mkdir /opt/jenkins/bin && mkdir /opt/jenkins/home && mkdir /opt/jenkins/cache

分别存放日志、插件、配置文件、war包、启动文件、工作目录、缓存

# mv /etc/default/jenkins /opt/jenkins/conf && ln -s /opt/jenkins/conf/jenkins /etc/default/jenkins

# mv /etc/init.d/jenkins /opt/jenkins/bin && ln -s /opt/jenkins/bin/jenkins /etc/init.d/jenkins

# mv /usr/share/jenkins/jenkins.war /opt/jenkins/lib

/opt/jenkins/conf/jenkins修改如下：

# arguments to pass to java

# Allow graphs etc. to work even when an X server is present

#JENKINS_LOG=daemon.info

# Whether to enable web access logging or not.
# Set to "yes" to enable logging to /var/log/$NAME/access_log
JENKINS_ENABLE_ACCESS_LOG="no"

# OS LIMITS SETUP
#   comment this out to observe /etc/security/limits.conf
#   this is on by default because http://github.com/jenkinsci/jenkins/commit/2fb288474e980d0e7ff9c4a3b768874835a3e92e
#   reported that Ubuntu's PAM configuration doesn't include pam_limits.so, and as a result the # of file
#   descriptors are forced to 1024 regardless of /etc/security/limits.conf
MAXOPENFILES=8192

# set the umask to control permission bits of files that Jenkins creates.
#   027 makes files read-only for group and inaccessible for others, which some security sensitive users
#   might consider benefitial, especially if Jenkins runs in a box that's used for multiple purposes.
#   Beware that 027 permission would interfere with sudo scripts that run on the master (JENKINS-25065.)
#
#   Note also that the particularly sensitive part of $JENKINS_HOME (such as credentials) are always
#   written without 'others' access. So the umask values only affect job configuration, build records,
#   that sort of things.
#
#   If commented out, the value from the OS is inherited,  which is normally 022 (as of Ubuntu 12.04,
#   by default umask comes from pam_umask(8) and /etc/login.defs

# UMASK=027

JENKINS_ARGS="--webroot=/opt/$NAME/cache/war --httpPort=$HTTP_PORT"

 

/opt/jenkins/bin/jenkins修改如下：

最后一步，修改/opt/jenkins目录所有者授权：

# userdel -rf jenkins && useradd -g root -m jenkins

# chown -R jenkins:root /opt/jenkins

否则jenkins启动不成功

# systemctl enable jenkins.service

# systemctl start jenkins.service

最后，启动jenkins成功，日志显示如下：
