Jenkins准备篇02-Jenkins部署安装

前面已经简单介绍jenkins持续集成,今天本篇文章主要针对“阿里云服务器安装Jenkins且进入Jenkins解锁页面”进行讲解。关于“jenkins页面设置”会在下一篇进行说明,希望感兴趣的小伙伴可以坚持看下去同时欢迎提出宝贵的意见让我们一起进步！

第一步：下载安装包

（1）linux命令为：wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war

[root@iZ2zebjpjfqq58nc6ul6hnZ package]# wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war

第二步：安装jdk

如何安装jdk在前面文章已介绍,具体见文章“https://www.jianshu.com/p/5ec40e6287c4”

第三步：启动Jenkins

（1）linux控制台启用命令为(退出控制台进程就关闭)：java -jar /root/package/jenkins.war --httpPort=8080
（2）linux后台启用命令为(后台一直运行)：nohup java -jar /root/package/jenkins.war --httpPort=8080 &
（3）linux后台启用命令为(打印启动日志)：nohup java -jar /root/package/jenkins.war --httpPort=8080 > jenkins.log 2>&1 &
（4）注意：根据自己安装包所在的路径启动命令

[root@iZ2zebjpjfqq58nc6ul6hnZ package]# java -jar /root/package/jenkins.war --httpPort=8080

第四步：将TCP端口号添加到安全组实例中

（1）阿里云服务器必须将TCP端口号添加到安全组实例中才能访问相关端口,否则在地址栏输入“http://ip:端口号”会报“无法访问此网站”错误

（2）如何将TCP端口号添加到安全组实例中前面文章已介绍,具体见文章“https://www.jianshu.com/p/5d1774c412a4”

第五步：进入解锁Jenkins页面

（1）在浏览器网址栏输入“http://59.110.230.1xx:端口号/”

解锁Jenkins.png

额外补充：

（1）注意：登录Jenkins主页的ip如果是虚拟机用内网IP ;如果是云服务器用外网IP
（2）云服务器查看外网IP命令为：curl cip.cc

[root@iZ2zebjpjfqq58nc6ul6hnZ ~]# curl cip.cc
IP  : 59.110.230.1XX
地址  : 中国  北京
运营商 : 阿里云/电信/联通/移动/铁通/教育网

数据二 : 北京市 | 阿里云

数据三 : 中国北京北京 | 阿里云

URL : http://www.cip.cc/59.110.230.1XX

（3）查看端口使用情况命令为：netstat -nltp

[root@iZ2zebjpjfqq58nc6ul6hnZ ~]# netstat -nltp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      25074/java          
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1022/sshd

（4）杀死一个进程命令为：kill -9 进程号

[root@iZ2zebjpjfqq58nc6ul6hnZ ~]# ps -ef |grep jenkins
root     25074 23090  1 00:20 pts/1    00:00:11 java -jar /root/package/jenkins.war --httpPort=8080
root     25748 23090  0 00:32 pts/1    00:00:00 grep --color=auto jenkins
root     25760 23090  0 00:33 pts/1    00:00:00 grep --color=auto jenkins
[root@iZ2zebjpjfqq58nc6ul6hnZ ~]# kill -9 25074
