Tech Command

docker wrong

docker 不能互相通信

具体表现：宿主机可以访问容器，容器不可以访问宿主机(可以ping通)，容器之间不可以互通

sysctl net.ipv4.ip_forward # 查看 forward 状态
sudo sysctl -w net.ipv4.ip_forward=1 #临时修改
sudo vim /etc/sysctl.conf # 永久生效，不存在就新建
# net.ipv4.ip_forward = 1
sudo sysctl -p # 立即生效

setenforce 0 # 临时生效 禁用 SELinux
# /etc/selinux/config 改 enforcing 为 disabled  # 永久生效
systemctl stop firewalld.service # 临时生效
systemctl disable firewalld.service # 永久生效

ssh -R 2222:localhost:22 -p 2222 lnks@home.test.cn #临时远程协助

docker 容器中的程序无法运行

具体表现是，安装了 kylinV10 Server 和 UOS V20 仓库自带 docker 后，运行后，容器内部程序涉及到多线程操作被拒绝的失败错误。此时安装官方的 docker 安装包即可解决。
