rpm安装jenkins启动后报错 UnknownHostException: centos68-192-168-18-4: Name or service not known

Question

1. jenkins 版本 jenkins-2.164.1-1.1.noarch.rpm
2. rpm安装方式安装成功后通过service jenkins start启动报错
3. hostname和/etc/hosts都已修改centos68

[root@centos68 work]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 centos68
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 centos68
127.0.0.1 centos68-192-168-18-4
192.168.18.4 centos68

1. 错误:
