dcoker安装脚本命令

如下命令可保存成docker-install.sh脚本执行即可

#!/bin/bash
echo "(1/11): 解压Docker安装文件..."
tar -zxvf docker-24.0.6.tgz
sleep 5
echo "(2/11): 文件解压完毕!开始迁移Docker文件..."
mv docker/* /usr/bin/
echo "(3/11): 迁移完成!开始将Docker添加到service服务..."

安装启动时遇到的问题

启动docker卡住无报错情况 可能是防火墙问题 先关闭防火墙再启动docker

    systemctl stop firewalld 关闭防火墙
    systemctl start firewalld 开启防火墙

docker卸载脚本

如下命令可保存成 docker-uninstall.sh 文件，并将如下内容粘贴进去。

#!/bin/bash
echo "(1/8): 开始删除Docker服务..."

echo '(2/8)停止docker'
systemctl stop docker

echo '(3/8)取消开机自启'
systemctl disable docker

echo '(4/8)取消注册文件'
rm -rf /etc/systemd/system/docker.service

echo '(5/8)删除docker相关文件'
rm -rf /usr/bin/containerd
rm -rf /usr/bin/containerd-shim
rm -rf /usr/bin/ctr
rm -rf /usr/bin/runc
rm -rf /usr/bin/docker*

echo '(6/8)删除docker配置'
rm -rf /etc/docker/

echo '(7/8)删除镜像/容器'
rm -rf /var/lib/docker

echo '(8/8)重新加载配置文件'
systemctl daemon-reload
echo '卸载成功!'

搭建docker容器服务器遇到的问题

容器之间通信遇到No route to host ，找到容器服务用到的网卡设置信任即可，默认为docker0

firewall-cmd --permanent --zone=trusted --change-interface=docker0
firewall-cmd --reload
