|NO.Z.00048|——————————|^^ 部署 ^^|——|CI/CD&Jenkins_Harbor部署.V05|——|部署_Jenkins|

一、CI/CD.Jenkins服务部署

### --- Jenkins服务部署配置

~~~     Jenkins服务部署说明
~~~     在centos7.2 10.10.10.12 192.168.1.12 jenkins服务器配置

### --- 安装Jenkins.repo源地址

[root@jenkins ~]# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
[root@jenkins ~]# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

### --- 安装Jenkins，Git，maven
~~~     查看java是否已经安装

[root@jenkins ~]# yum install -y jenkins git maven
[root@jenkins ~]# java -version                                             
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode) 

### --- 查看Java版本
~~~     查看java是否已经安装

[root@jenkins ~]# java -version                                             
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode) 

### --- 启动Jenkins

[root@jenkins ~]# systemctl start jenkins

~~~     查看Jenkins进程

[root@jenkins ~]# ps -ef|grep jenkins
jenkins   20817      1 99 21:40 ?        00:00:15 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8080 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20
root      20854  20503  0 21:40 pts/0    00:00:00 grep --color=auto jenkins

~~~     查看启动的8080端口

[root@jenkins ~]# lsof -i:8080
COMMAND   PID    USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    20817 jenkins  147u  IPv6  94236      0t0  TCP *:webcache (LISTEN)

二、预先配置

### --- Jenkins可以使用docker命令
~~~     由于在Jenkins机器上docker是使用root用户运行的，
~~~     而Jenkins是使用普通用户jenkins运行的，
~~~     所以要先配置下jenkins用户可以使用docker命令。

[root@docker ~]# visudo
jenkins ALL=(root)      NOPASSWD: /usr/bin/docker

### --- 另外在Jenkins机器上配置：

[root@docker ~]# visudo
jenkins ALL=(root)      NOPASSWD: /usr/bin/docker
Disable "ssh hostname sudo <cmd>", because it will show the password in clear.
        You have to run "ssh -t hostname sudo <cmd>".
#Defaults    requiretty
Defaults:jenkins !requiretty

### --- 确认
~~~     通过该命令查看docker的命令是否在/usr/bin/下

[root@docker ~]# which docker   
/usr/bin/docker 

### --- 如果不配置这个，在执行下面脚本时，会报错误：

+ cp -f /home/jenkins/.jenkins/workspace/godseyeBranchForNov/godseye-container/target/godseye-container-wisedu.war /home/jenkins/docker-file/godseye_war/godseye.war
+ sudo docker login -u jkzhao -p Wisedu123 -e 01115004@wisedu.com 172.16.206.32
sudo: sorry, you must have a tty to run sudo

---

三、安装Jenkins插件配置

### --- 登录Jenkins

~~~     ——>浏览器登录Jenkins：http://10.10.10.12:8080，http://192.168.1.12:8080进行初始化配置
~~~     ——>点击“系统管理”，点击“管理插件”，搜索插件"Maven Integration"和"SSH"，进行安装。
~~~     ——>SSH安装完成后为：SSH Plugin

### --- 查看Jenkins初始化密码

[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword
4a19650966bb42978f33f7f5e879644b

### --- 配置远程机器

~~~     ——>配置远程机器：登录Jenkins，点击“Credentials”，点击“Add domain”。
~~~     ——>Dashboard——>Manage Jenkins——>Manage Credentials
~~~     ——>Jenkins:添加域：域名/描述/OK——>返回到添加凭据域列表
~~~     ——>docker——>添加凭据——>添加一些凭据——>确定——>END
~~~     ——>点击“系统管理”，“系统配置”，找到“SSH remote hosts”。
~~~     ——>Dashboard——>Manage Jenkins——>Configure System——>SSH remote hosts
~~~     ——>Check connection——>保存——>END
