本文使用的安装工具为easzlab/kubeasz
2.1 修改docker目录
通过软连接的方式修改docker 数据存储路径
ansible new-node -i hosts -m shell -a 'mkdir /data/docker'
ansible new-node -i hosts -m shell -a 'cd /var/lib/ && ln -s /data/docker docker'
2.2 安装gluster fs依赖
如果pod需要用到gluster fs才需要执行此步骤
ansible new-node -i hosts -m shell -a 'yum install centos-release-gluster glusterfs-fuse -y'
2.3 安装ntpd确保时钟同步
# 安装ntd
ansible new-node -i hosts -m shell -a 'yum -y install ntp'
# 设置开机自启动
ansible new-node -i hosts -m shell -a 'systemctl enable ntpd'
# 启动ntpd服务
ansible new-node -i hosts -m shell -a 'systemctl start ntpd'
# 手动执行一次同步
ansible new-node -i hosts -m shell -a 'ntpdate -u 0.centos.pool.ntp.org'
2.4 添加新节点
easzctl add-node 192.168.1.11
新增kube-node节点大致流程为：tools/02.addnode.yml 见参考资料1
