centos7怎么关机 centos7怎么取消指令
CentOS 7关闭不必要的系统组件需先识别启用服务(systemctl list-unit-files --type=service | grep enabled),重点停用并卸载postfix、abrt*、NetworkManager、avahi-daemon等冗余项,禁用后须yum remove彻底清除二进制与配置,并用yum versionlock防止自动重装。

If you are not sure what to do and how to do it yourself, check the results and see how it works: systemctl list-unit-files --type=service | grep enabled ——查所有启用的服务重点关注这些典型可关项:postfix(邮件)、 abrt*(崩溃报告)、NetworkManager(如果你用静态/etc/sysconfig/network-scripts/ file systemctl status
很多教程只教 systemctl stop 和 systemctl disable,但实际中这俩操作只影响运行时和启动项,二进制、配置、日志全留着:postfix 占着:25?Light disable 不行,得 yum remove postfix -y卸载后手动清残留:rm -rf /etc/postfix /var/spool/postfix /var/log/maillog Check the new, sad, sad, happy, new, happy, sad, and sad again: yum versionlock add postfix(需先 yum install yum-plugin-versionlock)类似地,abrt系列服后台拉起其他子服务NetworkManager 和 network.service别同时开
CentOS 7 默认启用 NetworkManager.service,但传统服务器习惯用 network.service 管理网卡。
