一、Rockylinux换源，国外的源换成国内的源

#nmcli connection modify ens33 ipv4.addresses 192.168.121.11 ipv4.gateway 192.168.121.2 ipv4.method manual ipv4.dns 114.114.114.114 connection.autoconnect yes

修改地址

#systemctl stop firewalld

#systemctl diabled firewalld

#cd /etc/yum.repos.d/

#mv rocky* /a

阿里

sed -e 's|^#mirrorlist=|mirrorlist=|g' \

    -e 's|^baseurl=https://mirrors.aliyun.com/rockylinux|#baseurl=http://dl.rockylinux.org/$contentdir|g' \

    -i.bak \

    /etc/yum.repos.d/rocky*.repo

中科大

sed -e 's|^mirrorlist=|#mirrorlist=|g' \

    -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g' \

    -i.bak \

    /etc/yum.repos.d/rocky-extras.repo \

    /etc/yum.repos.d/rocky.repo

#yum config-manager --set-enabled crb 开启crb为Complete Releasabld Binding完全可释放绑定，轻松解决绑定或链接机制

#yum -y install epel-release 安装epel源，解决一些依赖关系

#yum -y install vim 安装vim

#yum -y install bash-completion 安装自动补齐

#sestatus

#vim 网卡的uuid删掉，移除

#sestatus   查看selinux状态

#vim  /etc/selinux/config

SELINUX=disabled

# setenforce 0   或者 reboot

#yum -y install epel-release     //安装epel源

#yum -y install bash-completion   //安装自动补齐

二、centos换源

#nmcli connection modify ens33 ipv4.addresses 192.168.121.11 ipv4.gateway 192.168.121.2 ipv4.method manual ipv4.dns 114.114.114.114 connection.autoconnect yes

修改地址

#systemctl stop firewalld

#systemctl diabled firewalld

#cd /etc/yum.repos.d/

#mv Centos* /a

#wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

#curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

其他步骤同上，还有设置的地址是能连接网络的地址
