误操作删除服务器上git仓库的处理方法
说明:
git 服务器上仓库代码不小心被删除了,但是通过git clone下来的code存在
另外git 服务器上没有建立任何branch信息;
1.在之前clone过服务器代码的客户端机器上,找到clone下来的代码目录,
执行git remote -vv
查询原来git 仓库所在服务器的IP地址以及路径;
2.根据步骤1上查询的结果,在服务器上找到对应路径,创建git仓库;
git init –bare
3.在客户端之前clone 代码所在目录,强制push客户端的代码至服务器
git push origin master –force
这样原来clone下来的代码以及change log等信息,就会被强制clone到服务器上;
说明:此处必须加–force选项,否则会因服务器上仓库信息与客户端仓库信息不匹配导致push失败

承接上K8s的安装教程,继续安装ISTIO。
因为ISTIO具备完整的监控,包括grafana/prometheus等,故需要先删除原集群的相关监控,然后按istio方式部署。
第一步:检查目标K8s是否满足安装istio的条件。
istio x precheck
第二步:安装示范DEMO
istioctl install --set profile=demo
安装结束后,可用命令检查是否安装完整
istioctl verify-install

使用kubespray安装k8s时,必须禁用IPV6,否则会导至请求以ipv6方式请求,从而最终无法安装docker-ce等。
第一步:编辑/etc/sysctl.conf配置,增加net.ipv6.conf.all.disable_ipv6=1

第二步:编辑/etc/sysconfig/network配置,增加 NETWORKING_IPV6=no

第三步:编辑/etc/sysconfig/network-scripts/ifcfg-ens33,确保IPV6INIT=no是存在。而ifcfg-ens33可能在不同的系统中,是不同的名字。可以先通过ls /etc/sysconfig/network-scripts/检查确认具体名字后,再修改。

第四步:关闭防火墙的开机自启动
systemctl disable ip6tables.service
第五步:执行sysctl -p或者reboot重启命令
第六步:使用ifconfig检查验证ipv6是否真的禁用。
