一、系统优化

关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
关闭selinux
sed -ri 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce 0

二、安装Jenkins

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --no-check-certificate
rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key

安装JAVA11
yum install -y fontconfig java-11-openjdk

切换java到11版本，否则新版Jenkins不让启动
alternatives --config java

There are 2 programs which provide 'java'.

java -version
openjdk version "11.0.20" 2023-07-18
OpenJDK Runtime Environment Bisheng (build 11.0.20+8)
OpenJDK 64-Bit Server VM Bisheng (build 11.0.20+8, mixed mode, sharing)

安装Jenkins

dnf -y install jenkins
systemctl start jenkins

找初始化密码
cat /var/lib/jenkins/secrets/initialAdminPassword
admin
4jMzcjzz2KOU3cdbUnmA
然后，输入 Ip:8080，进行初始化操作。

三、修改workspace路径

华为欧拉系统默认/home路径为大空间，需要将默认装的Jenkins路径，修改到/home/jenkins下。
如果Jenkins已经使用，操作前提是你先把原来的数据mv到你需要的路径哦，copy前建议先关闭jenkins。

关闭jenkins
systemctl stop jenkins

查看jenkins安装路径
rpm -ql jenkins

/usr/bin/jenkins
/usr/lib/systemd/system/jenkins.service
/usr/share/java/jenkins.war
/usr/share/jenkins/migrate
/var/cache/jenkins
/var/lib/jenkins

vim /usr/lib/systemd/system/jenkins.service查看本来的workspace路径，把数据移走
mv /var/lib/jenkins/ /home/
vim /usr/lib/systemd/system/jenkins.service 改资料

# $JENKINS_WEBROOT.
User=root
Group=root
# Directory where Jenkins stores its configuration and workspaces
Environment="JENKINS_HOME=/home/jenkins"
WorkingDirectory=/home/jenkins

systemctl daemon-reload 使得配置生效
service jenkins restart 重启jenkins
chkconfig jenkins on 设置开机自启动
