jenkins介绍

 

 jenkins安装

1.安装openjdk

[root@centos-03 ~]# yum install -y java-1.8.0-openjdk

2.安装Jenkins yum源

[root@centos-03 ~]# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo

3.安装Jenkins  key

[root@centos-03 ~]# rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key
[root@centos-03 ~]# 

4.yum安装

[root@centos-03 ~]# yum install -y jenkins

5.启动Jenkins

[root@centos-03 ~]# systemctl start jenkins
[root@centos-03 ~]# ps aux|grep jenkins
jenkins    3492 64.2  6.2 2252192 62356 ?       Ssl  15:38   0:21 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/libjenkins -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       3513  1.0  0.0 112664   936 pts/0    R+   15:39   0:00 grep --color=auto jenkins
[root@centos-03 ~]# 

6.我们可以在Jenkins日志中查看jenkins密码，或是在initialAdminPassword文件中查看

[root@centos-03 yum.repos.d]# less /var/log/jenkins/jenkins.log 
[root@centos-03 yum.repos.d]# 
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:

8a72142953e9417f81970ffcb9366194

This may also be found at: /var/lib/jenkins/secrets/initialAdminPassword

[root@centos-03 yum.repos.d]# cat /var/lib/jenkins/secrets/initialAdminPassword 
8a72142953e9417f81970ffcb9366194
[root@centos-03 yum.repos.d]# 

了解jenkins

1.浏览器访问192.168.133.66:8080进入jenkins页面，填写密码，选择安装推介插件。

2.安装完插件后创建第一个管理员用户，下一步安装成功

3.jenkins配置文件目录

[root@centos-03 yum.repos.d]# vim /etc/sysconfig/jenkins 
[root@centos-03 yum.repos.d]# 

4.程序主目录（如果想备份，直接拷贝这个目录就可以了）

[root@centos-03 yum.repos.d]# cd /var/lib/jenkins/

[root@centos-03 jenkins]# ls
config.xml                                      nodeMonitors.xml
hudson.model.UpdateCenter.xml                   nodes  （多节点的时候用到的目录）
hudson.plugins.git.GitTool.xml                  plugins （插件目录）
identity.key.enc                                secret.key
jenkins.CLI.xml                                 secret.key.not-so-secret
jenkins.install.InstallUtil.installingPlugins   secrets
jenkins.install.InstallUtil.lastExecVersion     updates
jenkins.install.UpgradeWizard.state             userContent
jenkins.model.JenkinsLocationConfiguration.xml  users
jobs     （我们创建的任务所在的目录）                                       workflow-libs
logs     （日志相关目录）
[root@centos-03 jenkins]#

发布php代码(上)　　

1.在创建任务之前我们需要安装必须的两个插件系统管理-》管理插件-》已安装插件列表中看是否安装了Git plugin和publish over ssh，发现没有publish over ssh我们从可选插件中安装，选中直接安装，安装完成之后，linux服务器直接重启Jenkins。

[root@centos-03 jenkins]# systemctl restart jenkins
[root@centos-03 jenkins]# 

2.在配置publish over ssh之前需要生成一对秘钥，如果服务器上有默认的秘钥对可以不生成直接用

[root@centos-03 jenkins]# 
[root@centos-03 jenkins]# cd /root/.ssh/
[root@centos-03 .ssh]# ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
[root@centos-03 .ssh]# 

3.将私钥填到key中　　

[root@centos-03 .ssh]# cat id_rsa
-----BEGIN RSA PRIVATE KEY-----

[root@centos-03 .ssh]# 

系统管理-》系统设置找到下面选项，将key填上

4.将公钥配置到远程机器上（centos-02）

[root@centos-03 .ssh]# cat id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDYzwzucn1JkSSXBDNAZ9KNAbRFLUGn27xeJ/3H7bkXC8FpdNfesSuoHDHg3+RxLnOa7h5M2fLb/ThvPzpl8BA5PYdzY+adqjYzkaCubU/Yjt5GvZV0lTJN+Xsxf8X4wXQtZKQdgKKf+ejo6O7

5.测试ssh是否能登录

[root@centos-03 .ssh]# ssh centos-02
The authenticity of host 'centos-02 (192.168.133.88)' can't be established.
ECDSA key fingerprint is bf:dc:4b:e3:1c:99:f4:12:6f:d0:a8:e0:13:8a:d0:dd.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'centos-02' (ECDSA) to the list of known hosts.
Last login: Mon Jun 25 18:53:00 2018 from 192.168.133.1
[root@centos-02 ~]# 

5.配置ssh server

6.点击test测试成功

7.保存即可

发布php代码(下)

 

1.点击新建任务填写任务名点击构建一个自由风格的软件项目

2.填写描述，源码管理选择git

3.配置完成点击保存，构建环境

 

4.如图

5.点击立即构建

6.构建失败，原来是服务器没有安装git，yum安装

[root@centos-03 linux_php]# yum install -y git

7.重新构建成功

8.查看日志

[root@centos-02 tmp]# pwd
