如果安装了防火墙，则必须将 Jenkins 添加为例外。 您必须在下面的脚本中更改为要使用的端口

YOURPORT=8080
PERM="--permanent"
SERV="$PERM --service=jenkins"

firewall-cmd $PERM --new-service=jenkins
firewall-cmd $SERV --set-short="Jenkins ports"
firewall-cmd $SERV --set-description="Jenkins port exceptions"
firewall-cmd $SERV --add-port=$YOURPORT/tcp
firewall-cmd $PERM --add-service=jenkins
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload

?使用

首次访问新的 Jenkins 实例时，系统会要求您使用 自动生成的密码

1. 浏览到（或您为其配置的任何端口） Jenkins）并等待?Unlock Jenkins?页面出现

http://localhost:8080

2.?从 Jenkins 控制台日志输出中，复制自动生成的 字母数字密码（在 2 组星号之间）

?也可以执行命令查看密码

sudo cat /var/lib/jenkins/secrets/initialAdminPassword
