Centos、Ubuntu、Debian、Fedora、OpenSUSE、FreeBSD系统换软件源 Linux系统安装完后软件源一般都是国外服务器，在国内特别慢，这时候就需要更换国内的镜像源。 **高性价比和便宜的VPS/云服务器推荐：**[https://blog.zeruns.tech/archives/383.html](https://blog.zeruns.tech/archives/383.html) ## Centos ### 1、备份 ``` mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup ``` ### 2、更换源 下载新的`CentOS-Base.repo`到`/etc/yum.repos.d/` ``` wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo ``` 或者 ``` curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo ``` 注意`http://mirrors.aliyun.com/repo/Centos-7.repo`中的`7`改为自己的Centos版本号，比如Centos 8就是`http://mirrors.aliyun.com/repo/Centos-8.repo`。 ### 3、运行yum makecache生成缓存 ``` yum makecache ``` ## Ubuntu ### 1.备份 ``` sudo cp /etc/apt/sources.list /etc/apt/sources_init.list ``` 将以前的源备份一下，以防以后可以用的。 ### 2.更改文件权限使其可编辑 ``` sudo chmod 777 /etc/apt/source.list ``` ### 3.更换源 ``` sudo nano /etc/apt/sources.list ``` 使用nano打开文本，删除原来文件里的内容，将下面其中一个源复制进去，然后保存。 **阿里源：** ``` deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse ``` **清华源：** ``` deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse ``` ### 3.更新 更新源 ``` sudo apt-get update ``` 修复损坏的软件包，尝试卸载出错的包，重新安装正确版本的。 ``` sudo apt-get -f install ``` 更新软件 ``` sudo apt-get upgrade ``` ## Debian ### 1.备份 ``` sudo cp /etc/apt/sources.list /etc/apt/sources.list_bak ``` ### 2.更换源 一般情况下，将`/etc/apt/sources.list`文件中 Debian 默认的源地址`http://deb.debian.org`替换为`http://mirrors.ustc.edu.cn`（清华源）即可。 ``` sudo sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list ``` 也可以直接编辑`/etc/apt/sources.list`文件（v） ``` sudo vi /etc/apt/sources.list ``` 加入如下内容即可 ``` deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian stable main contrib non-free deb http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free # deb http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free ``` 敲击`i`键进入插入模式，组合键`ctrl+shift+v`将复制内容粘贴至源文件中，敲击esc键进入命令模式，输入`:wq!`保存并退出。 其他镜像源： 阿里云：http://mirrors.aliyun.com/ 搜狐：http://mirrors.sohu.com/ 网易：http://mirrors.163.com/ ### 3.更新 ``` sudo apt-get update ``` ## Fedora ``` su cd /etc/yum.repos.d/ mv fedora.repo fedora.repo.backup mv fedora-updates.repo fedora-updates.repo.backup wget -O /etc/yum.repos.d/fedora.repo http://mirrors.aliyun.com/repo/fedora.repo wget -O /etc/yum.repos.d/fedora-updates.repo http://mirrors.aliyun.com/repo/fedora-updates.repo dnf clean all dnf makecache ``` ## OpenSUSE ### 1.禁用原有软件源 ``` sudo zypper mr -da ``` ### 2.添加科大镜像源 ``` sudo zypper ar -fc https://mirrors.ustc.edu.cn/opensuse/distribution/leap/42.1/repo/oss USTC:42.1:OSS sudo zypper ar -fc https://mirrors.ustc.edu.cn/opensuse/distribution/leap/42.1/repo/non-oss USTC:42.1:NON-OSS sudo zypper ar -fc https://mirrors.ustc.edu.cn/opensuse/update/leap/42.1/oss USTC:42.1:UPDATE-OSS sudo zypper ar -fc https://mirrors.ustc.edu.cn/opensuse/update/leap/42.1/non-oss USTC:42.1:UPDATE-NON-OSS ``` ### 3.手动刷新软件源 ``` sudo zypper ref ``` ### 4.更新系统 ``` sudo zypper up ``` ## FreeBSD ### 1.修改 pkg 源 ```shell mkdir -p /usr/local/etc/pkg/repos vim /usr/local/etc/pkg/repos/FreeBSD.conf # content of FreeBSD.conf FreeBSD: { url: "pkg+http://mirrors.ustc.edu.cn/freebsd-pkg/${ABI}/quarterly", } ``` ### 2.修改 ports 源 ``` vim /etc/make.conf # content of make.conf FETCH_CMD=axel -n 10 -a DISABLE_SIZE=yes MASTER_SITE_OVERRIDE?=http://mirrors.ustc.edu.cn/freebsd-ports/distfiles/${DIST_SUBDIR}/ ``` ### 3.修改 portsnap 源 ``` vim /etc/portsnap.conf # content of porsnap.conf SERVERNAME=porsnap.tw.freebsd.org ``` ##
