安装ansible：

yum -y install epel-release
yum -y install ansible

安装jinja2：

easy_install pip pip2
install jinja2 --upgrade

安装python3.6：

yum -y install python36

生成ssh公钥和私钥：

ssh-keygen
vi /etc/ssh/sshd_config
PasswordAuthentication yescd kubespray-2.6.0
PermitRootLogin yes
systemctl restart sshd.service

将公钥分发给机器:

ssh-copy-id [email protected]
ssh-copy-id [email protected]
ssh-copy-id [email protected]
ssh-copy-id [email protected]
ssh-copy-id [email protected]

官网下载kubespray：

wget https://github.com/kubernetes-sigs/kubespray/archive/v2.6.0.tar.gz
cd kubespray-2.6.0
pip install -r requirements.txt
cp -r inventory/sample inventory/mycluster

使用inventory_builder，初始化inventory文件:

declare -a IPS=(192.168.136.111 192.168.136.112 192.168.136.113 192.168.136.114 192.168.136.115 192.168.136.116)
CONFIG_FILE=inventory/mycluster/hosts.ini python36 contrib/inventory_builder/inventory.py ${IPS[@]}

vim inventory/mycluster/hosts.ini

强制更新requets库：

pip install --ignore-installed requests

下载谷歌镜像需要翻墙，设置代理：

vim /lib/systemd/system/docker.service
