背景:
我们直接用yum install 下载安装包,因为用的是国外的源,下载速度难免会受限,我们可以改为用阿里源,当然你不改也是没问题的。还有因为在手机安装的linux是安装在一个容器里的,当我们使用systemctl命令时,无法启用服务,提示:Running in chroot, ignoring request. 百度了很多,找到有可以替代的方法。

用vim编辑 /etc/yum.conf 文件,找到 plugins=1 这一行改为0即可
vim /etc/yum.conf
?二,替换yum源为阿里源
先用cat /etc/redhat-release 命令查看自己的系统版本
cat /etc/redhat-release
?用vim编辑文件:/etc/yum.repos.d/CentOS-Base.repo
编辑前先备份,用cp命令复制一份
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bk_20220508
将下面的 7.9.2009 换成你自己当前系统的版本号 适用于aarch64构架的阿里云镜像源配置文件
用 vim?/etc/yum.repos.d/CentOS-Base.repo 编辑文件
可以用命令ggdG 快速清空当前文件,在命令模式下,首先执行 gg 这里是跳至文件首行 再执行: dG 也就是直接按 ggdG 这样就清空了整个文件,然后用下面的内容粘贴替换,:wq保存退出。
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

更新下载新的rpm秘钥: 下面的7.9.2009替换成自己的版本号 下载地址: https://mirrors.aliyun.com/centos-altarch/7.9.2009/os/aarch64/ 下载 需要的两个文件: RPM-GPG-KEY-CentOS-7? RPM-GPG-KEY-CentOS-Testing-7
然后在这个/etc/pki/rpm-gpg/目录下把原来的替换掉,替换之前也要有做备份的习惯
然后执行更新命令
yum makecache 下载需要点时间,主要看你网络
yum makecache
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7-aarch64
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
?三,添加环境变量
这里默认/usr/local/bin并不在系统变量中,我们需要在/etc/bashrc中添加它
echo export PATH=$PATH:/usr/local/bin >> /etc/bashrc
四,寻找systemctl的替代品
执行systemctl start cpolar命令时,无法启动服务,提示以下信息。
?可以用以下方法解决:
# 下载包并解压
wget https://github.com/smaknsk/servicectl/archive/1.0.tar.gz
# 解压指定到路径
tar -xf 1.0.tar.gz -C /usr/local/lib/
# 软链接
ln -s /usr/local/lib/servicectl-1.0/servicectl /usr/local/bin/servicectl
ln -s /usr/local/lib/servicectl-1.0/serviced /usr/local/bin/serviced
使用方法: servicectl: sudo servicectl [action] [service] ?此命令仅执行文件 /usr/lib/systemd/system/${service}.service中的${action}, 如果通过的操作启用或禁用,则 servicectl将在 ${service}.service上创建或删除symlink以供使用服务。?
参数: action ?- 可以是 {start, stop, restart, reload, enable, disable} service - 在/usr/lib/systemd/system/文件夹中的文件
例如:
# inside chroot
sudo servicectl start mariadb
serviced: sudo serviced [action] ?此命令执行 ${action} 为所有启用服务。?
参数: action -默认是start,也可以是: {start, stop, restart, reload, disable}
例如:
# outside chroot:?
# init startup and run all enabled daemons
sudo chroot /path/to/chroot serviced
