istio 1.1及以上的版本需要k8s在1.11版本，但是实验室k8s版本是1.10 无语 没办法 还是得继续搬砖

具体步骤：
1 helm2安装 不做详细介绍
2 下载isito
wget https://github.com/istio/istio/releases/download/1.0.0/istio-1.0.0-linux.tar.gz
tar -zvxf istio-1.0.0-linux.tar.gz
3 安装配置环境变量
[root@centos-110 istio-1.0.0]# vim /etc/profile
在profile文件底部，增加如下一行：
export PATH=$PATH:/root/istio/istio-1.0.0/bin
执行source命令，使修改马上生效
[root@centos-110 istio-1.0.0]# source /etc/profile
[root@centos-110 istio-1.0.0]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/istio/istio-1.0.0/bin
验证istioctl 安装成功
[root@centos-110 bin]# istioctl version
