我看见

我可以访问sudo. 我试过了

[ec2-user@ip-172-99-99-99 Weekly Report]$ sudo su - jenkins

drwxr-xr-x 7 jenkins jenkins 4096 Jan 28 09:00 .

我需要以 Jenkins 用户的身份执行命令来解决 Maven 问题。

我正在遵循本指南

https://www.linuxtechi.com/configure-domainkeys-with-postfix-on-centos-7/

当我到达本节时，它给出了一个错误

# opendkim-default-keygen
Generating default DKIM keys:
Cannot determine host's domain name, so skipping default key generation.

我确实设置了主机名

# hostname
domain.org

# cat /etc/hostname
domain.org

# cat /etc/hosts
# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.redhat.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
#     /etc/cloud/cloud.cfg or cloud-config from user-data
#
# The following lines are desirable for IPv4 capable hosts
127.0.0.1 domain domain.org
127.0.0.1 localhost.localdomain localhost
127.0.0.1 localhost4.localdomain4 localhost4

# The following lines are desirable for IPv6 capable hosts
::1 domain domain.org
::1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=domain.org
NOZEROCONF=yes

（我用 . 替换了所有域名实例domain。）

网上其他页面只说设置主机名，就是设置好了。

# cat /etc/centos-release
CentOS Linux release 7.5.1804 (Core)
centos hostname
