centos atomic host安装完成会，第一次启动时会调用cloud-init等服务。这是个什么东东？
cloud-init用于在创建虚拟机时通过元数据服务对虚拟机基本配置，包括常见的主机名，用户，密码等等。cloud-init会在启动的过程中分四个阶段运行，按照时间顺序分为：
cloud-init-localcloud-initcloud-configcloud-final控制cloud-init配置行为的方式有两种：cloudinit的配置文件(/etc/cloud/cloud.cfg)和数据源（如openstack及ec2中的userdata）
系统安装时我禁用cloud-init，以下就是atomic的cloud-init本地配置文件
# cat cloud.cfg users: - default disable_root: 1 # 禁用root远程登录 ssh_pwauth: 0 # 禁用ssh密码认证, 改为1 locale_configfile: /etc/sysconfig/i18n mount_default_fields: [~, ~, 'auto', 'defaults,nofail', '0', '2'] resize_rootfs_tmp: /dev ssh_deletekeys: 0 ssh_genkeytypes: ~ syslog_fix_perms: ~ cloud_init_modules: - migrator - bootcmd - write-files - growpart - resizefs - set_hostname - update_hostname - update_etc_hosts - rsyslog - users-groups - ssh cloud_config_modules: - mounts - locale - set-passwords - yum-add-repo - package-update-upgrade-install - timezone - puppet - chef - salt-minion - mcollective - disable-ec2-metadata - runcmd cloud_final_modules: - rightscale_userdata - scripts-per-once - scripts-per-boot - scripts-per-instance - scripts-user - ssh-authkey-fingerprints - keys-to-console - phone-home - final-message system_info: default_user: name: centos lock_passwd: true # centos用户被锁密码，改为false passwd: $6$MySalt$0jzR1u/sSfVjQ2h6Udn4reCOEjj9/.pVHfAp7bWDoUd7cfi0GYsFqn9EL9a2MQP4sMZoVOlX4UeGKVUbwYE/N. #增加：设置密码 gecos: Cloud User groups: [wheel, adm, systemd-journal] sudo: ["ALL=(ALL) NOPASSWD:ALL"] shell: /bin/bash distro: rhel paths: cloud_dir: /var/lib/cloud templates_dir: /etc/cloud/templates ssh_svcname: sshd # vim:syntax=yaml posted on 2016-08-18 16:14 北京涛子 阅读( ...) 评论( ...) 编辑 收藏转载于:https://www.cnblogs.com/liujitao79/p/5784325.html
