使用tomcat搭建Jenkins環境(centos7.3)

1.從官網下載最新版本的tomcat
下載地址:https://tomcat.apache.org/
2.Jenkins 官方網站下載最新版本war包
Jenkins官網地址:http://jenkins-ci.org/
3.安裝Jenkins
步驟一、將jenkins的war包拷貝到 $TOMCAT_HOME/webapps 下(不用解壓),刪除 webapps 下其他目錄
步驟二、建立存放jenkins資料的目錄,並新增環境變數,命令如下:

mkdir /jenkins
vi /etc/profile 新增 export JENKINS_HOME=/jenkins

步驟三、寫啟動jenkins服務指令碼,命令如下:

vi /etc/init.d/jenkins 

新增如下內容,如果你希望用指定使用者啟動,請修改 JENKINS_USER=root 的值,但要記得更改 /jenkins 以及Tomcat 目錄的訪問許可權。另外其他環境變數例如 JAVA_HOME 和 TOMCAT_HOME 要根據你實際JDK和Tomcat的安裝目錄修改。

#!/bin/sh 
# 
# Startup script for the Jenkins Continuous Integration server 
# (via Jakarta Tomcat Java Servlets and JSP server) 
# 
# chkconfig: - 85 15 
# description: Jakarta Tomcat Java Servlets and JSP server 
# processname: tomcat 
# pidfile: /var/run/tomcat.pid 

# Set Tomcat environment. 
JENKINS_USER=root 
LOCKFILE=/var/lock/jenkins 
export PATH=/usr/local/bin:$PATH 
export HOME=/jenkins 
export JAVA_HOME=/opt/jdk1.8.0_161 
export JENKINS_BASEDIR=/jenkins 
export TOMCAT_HOME=/opt/apache-tomcat-9.0.8 
export CATALINA_PID=$JENKINS_BASEDIR/jenkins-tomcat.pid 
export CATALINA_OPTS="-DJENKINS_HOME=$JENKINS_BASEDIR/jenkins-home -Xmx512m -Djava.awt.headless=true" 

[ -f $TOMCAT_HOME/bin/catalina.sh ] || exit 0 

export PATH=$PATH:/usr/bin:/usr/local/bin 

# See how we were called. 
case "$1" in 
start) 
# Start daemon. 
echo -n "Starting Tomcat: " 
su -p -s /bin/sh $JENKINS_USER -c "$TOMCAT_HOME/bin/catalina.sh start" 
RETVAL=$? 
echo 
[ $RETVAL = 0 ] && touch $LOCKFILE 
;; 
stop) 
# Stop daemons. 
echo -n "Shutting down Tomcat: " 
su -p -s /bin/sh $JENKINS_USER -c "$TOMCAT_HOME/bin/catalina.sh stop" 
RETVAL=$? 
echo 
[ $RETVAL = 0 ] && rm -f $LOCKFILE 
;; 
restart) 
$0 stop 
$0 start 
;; 
condrestart) 
[ -e $LOCKFILE ] && $0 restart 
;; 
status) 
status tomcat 
;; 
*) 
echo "Usage: $0 {start|stop|restart|status}" 
exit 1 
esac 

exit 0


步驟四、賦予啟動指令碼可執行許可權,並設定開機啟動,命令如下:

chmod a+x /etc/init.d/jenkins 
chkconfig jenkins on 
service jenkins start 

步驟五、http://192.168.1.171:8080/jenkins/ 可以看到 Jenkins 已經啟動了
佈置 Nginx 做一下反向代理
步驟一、下載並安裝nginx
步驟二、編輯nginx啟動檔案,命令如下:

vi /etc/nginx/nginx.conf

修改成如下內容

user root;
worker_processes auto;
error_log /var/log/nginx/error.log error;

events {
    worker_connections 10240;
}

http{
    server {
        listen       80;
        server_name  ci.abc.com;
        client_max_body_size 60M;
        client_body_buffer_size 512k;
        location / {
            proxy_pass      http://localhost:8080;
            proxy_redirect  off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }
}

啟動nginx service nginx start
步驟三、修改本機hosts檔案(C:\Windows\System32\drivers\etc\hosts)
192.168.1.171 ci.abc.com
步驟四、訪問
這次我們在瀏覽器裡輸入 http://ci.abc.com/jenkins 可以看到頁面了!
