1）線上安裝jenkins

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

最新的jenkins都要求java版本在7以上，不然會啟動失敗。

yum remove java
yum install java-1.7.0-openjdk

建議用supervisorctl管理linux啟動項。

yum install python-setuptools
easy_install supervisor

[unix_http_server]
file = /var/run/supervisord_mongo.sock
chmod = 0777
chown= root:root

[inet_http_server]
# Web管理介面設定
port=127.0.0.1:9003
username = qlog
password = qlog

[supervisorctl]
; 必須和'unix_http_server'裡面的設定匹配
serverurl = unix:///var/run/supervisord_mongo.sock

[supervisord]
logfile=/data/logs/supervisord_waterfall.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10          ; (num of main logfile rotation backups;default 10)
loglevel=info               ; (log level;default info; others: debug,warn,trace)
pidfile=/var/run/supervisord_waterfall.pid ; (supervisord pidfile;default supervisord.pid)
#nodaemon=true              ; (start in foreground if true;default false)
minfds=1024                 ; (min. avail startup file descriptors;default 1024)
minprocs=200                ; (min. avail process descriptors;default 200)
user=root                 ; (default is current user, required if root)
childlogdir=/var/log/supervisord/            ; ('AUTO' child log dir, default $TEMP)
identifier = supervisor

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[include]
files = /usr/local/apps/supervisor/*.conf
 

[program:jenkins]
command=java -jar /usr/lib/jenkins/jenkins.war —httpPort=9100
directory=/root/
autostart = true
startsecs = 5
stopsignal=TERM
autorestart=true
numprocs=1
user = root
redirect_stderr = true
stdout_logfile = /data/logs/jenkins.log

supervisord -c /etc/supervisord.conf
 

jenkins啟動成功後，直接在瀏覽器中就能開啟對應的埠（如http://x.x.x.x:9100）進行配置。

第一步是更新各種外掛，比如git/github外掛。

第二步是安裝修改一些系統環境，比如maven/nodejs等。

第三步可能需要配置你的github賬戶，這裡注意jenkins裡面需要的是你賬戶名與私鑰，並非ssh key的公鑰。

第四步是建立一個job任務，配置github源，以及你需要編譯的步驟指令碼等，如下grunt編譯操作：

#!/usr/bin/env bash

# kill jinx drive
ID=`ps -ef | grep 'grunt' | awk '{print $2}'`
for id in $ID
do
   echo "kill process $id"
   kill -9 $id
done

cd /root/.jenkins/jobs/nimble/workspace
echo "bower install -allow-root"
bower install -allow-root

echo "npm install"
npm install

echo "grunt build"
grunt build

echo "grunt serve:dist >> /root/.jenkins/jobs/nimble/workspace/nimbleRun.log 2>&1 &"
nohup grunt serve:dist >> /root/.jenkins/jobs/nimble/workspace/nimbleRun.log 2>&1 &

5）總結

jenkins是個非常輕量級的持續整合開源軟體，各種外掛也非常好用，特別是和git/githut的無縫連結，極大地解放了系統整合的生產力。
