3. 修改jenkins配置

vi /etc/sysconfig/jenkins

修改内容JENKINS_USER 为root,  JENKINS_PORT改为80  ：

## Type:        string
## Default:     "jenkins"
## ServiceRestart: jenkins
#
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="root"

## Type: integer(0:65535)
## Default: 8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="80"

4. 重启服务

systemctl restart jenkins

5. 修改jenkins的java路径配置

vi /etc/init.d/jenkins 

# Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html
candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/lib/jvm/java-11.0/bin/java
/usr/lib/jvm/jre-11.0/bin/java
/usr/lib/jvm/java-11-openjdk-amd64
/usr/bin/java
"

修改内容：

candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/lib/jvm/java-11.0/bin/java
/usr/lib/jvm/jre-11.0/bin/java
/usr/lib/jvm/java-11-openjdk-amd64
/usr/bin/java
/root/soft/jdk1.8.0_261/bin/java
"

6.重启服务

[root@jenkins-node ~]# systemctl daemon-reload
[root@jenkins-node ~]# systemctl restart jenkins

 7. 此时/var/lib/jenkins/ 目录下内容

[root@jenkins-node jenkins]# ll
total 36
-rw-r--r--. 1 root root 1655 Jan  8 05:56 config.xml
-rw-r--r--. 1 root root   58 Jan  8 05:55 failed-boot-attempts.txt

drwxr-xr-x. 2 root root   24 Jan  8 05:56 userContent
drwxr-xr-x. 3 root root   56 Jan  8 05:56 users

8. 浏览器中访问jenkins服务IP+端口号

http://10.0.0.200/

出现页面

此时/var/lib/jenkins/ 目录下内容 多了updates目录

[root@jenkins-node jenkins]# ll
total 32
-rw-r--r--. 1 root root 1638 Jan  8 05:59 config.xml
-rw-r--r--. 1 root root  156 Jan  8 05:56 hudson.model.UpdateCenter.xml
-rw-------. 1 root root 1712 Jan  8 05:56 identity.key.enc
-rw-r--r--. 1 root root    5 Jan  8 05:56 jenkins.install.UpgradeWizard.state

drwxr-xr-x. 2 root root    6 Jan  8 05:56 nodes
drwxr-xr-x. 2 root root    6 Jan  8 05:56 plugins
-rw-r--r--. 1 root root  129 Jan  8 05:56 queue.xml.bak
-rw-r--r--. 1 root root   64 Jan  8 05:56 secret.key
-rw-r--r--. 1 root root    0 Jan  8 05:56 secret.key.not-so-secret
drwx------. 4 root root  265 Jan  8 05:56 secrets
drwxr-xr-x. 2 root root   67 Jan  8 05:59 updates
drwxr-xr-x. 2 root root   24 Jan  8 05:56 userContent
drwxr-xr-x. 3 root root   56 Jan  8 05:56 users

 9. 国内镜像加速

9.1 修改hudson.model.UpdateCenter.xml  为清华源

  vi /var/lib/jenkins/hudson.model.UpdateCenter.xml

<?xml version='1.1' encoding='UTF-8'?>
<sites>
<site>
<id>default</id>
<url>https://updates.jenkins.io/update-center.json</url>
</site>
</sites>

修改内容为：

<?xml version='1.1' encoding='UTF-8'?>
<sites>
  <site>
    <id>default</id>
    <url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url>
  </site>
</sites>

重启

[root@jenkins-node ~]# systemctl restart jenkins

 9.2 修改/var/lib/jenkins/updates/default.json 

cd /var/lib/jenkins/updates/

使用sed命令替换  文件内容中的搜索为百度 ，下载服务方为清华源

sed -i 's#https://updates.jenkins.io/download#https://mirrors.tuna.tsinghua.edu.cn/jenkins#g' default.json && sed -i 's#http://www.google.com#https://www.baidu.com#g' default.json

重启

[root@jenkins-node ~]# systemctl restart jenkins

10. 获取初始登录密码，输入密码，登录系统

cat /var/lib/jenkins/secrets/initialAdminPassword

 选择推荐安装插件 等待安装完即可。

附踩坑记录

1. [jenkins] 启动错误 Failed to start LSB

2. 如果安装完访问不了，查看下防火墙

[root@jenkins-node jenkins]# systemctl status firewalld.service
[root@jenkins-node jenkins]# systemctl stop firewalld.service
