Fedora开机启动速度的优化

一直认为我的虚拟机性能不够所以导致自己的机器开桌面环境,开机慢慢慢慢慢慢…….今天终于发现了原因……是自己的傻(╯‵□′)╯︵┻━┻ ……

过程

使用systemd-analyze 命令
使用systemd-analyze blame 命令罗列所有的启动的服务和耗时

我的机器耗时间最长的是

  1. dnf-makecache.service 占用了 1min 8.124s;
  2. plymouth-quit-wait.service 占用了 1min 744ms

重点来了

所以关闭它,阻止今后开机的时候启动

systemctl disable dnf-makecache.service
systemctl disable dnf-makecache.timer
OR
systemctl mask dnf-makecache.service
systemctl mask dnf-makecache.timer
systemctl mask plymouth-quit-wait.service
systemctl mask firewalld.service

尽量不使用DHCP使用固定的IP可以提高启动速度,其他的不需要服务可以自行关闭即可

优化后的结果

Startup finished in 3.091s (kernel) + 1.669s (initrd) + 5.211s (userspace) = 9.971s
