Ubuntu 18.04 下部署k8s
一 、更新Ubuntu源
mv /etc/apt/sources.list /etc/apt/sources.list.bakcat /etc/apt/sources.list.bak |grep -v "#" |grep -v "^#34; >sources.listsed -i s/archive.ubuntu.com/mirrors.ustc.edu.cn/g /etc/apt/sources.listsed -i s/security.ubuntu.com/mirrors.ustc.edu.cn/g /etc/apt/sources.listapt -y update && apt -y upgrade# 2 、timedatectlsed -i s/en_US/C/g /etc/default/localetimedatectl set-timezone Asia/Shanghai# 3、bash-completionsed -i 97,99s/#//g /root/.bashrc# 4、sshecho "PermitRootLogin yes" >>/etc/ssh/sshd_configpasswd root << "EOF"passwordpasswordEOFsystemctl reload ssh# 5 、hostsvim /etc/hosts10.0.0.20 k8s-master0010.0.0.21 k8s-master0110.0.0.22 k8s-master0210.0.0.23 k8s-node0110.0.0.24 k8s-node0210.0.0.25 k8s-bl-master# 6
