Linux 安装docker
- 安装依赖：
yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
- 设置仓库
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
- 安装docker
yum install docker-ce docker-ce-cli containerd.io
注意： 如果安装失败 报错（but none of the providers can be installed）
解决方法：
yum list docker-ce --showduplicates | sort -r //检查相应的软件包版本
yum -y install docker-ce-18.06.0.ce-3.el7 //安装低版本的软件包
wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm //下载相关软件包
yum -y install containerd.io-1.2.6-3.3.el7.x86_64.rpm //升级containerd.io软件包 如果在此过程中安装失败再重新执行这个命令即可有可能是网络问题
安装完成后重新安装Docker
yum -y install docker-ce //安装Docker软件包
安装完成后启动Docker
[root@localhost ~]# systemctl start docker //启动并加入开机启动
systemctl enable docker
[root@localhost ~]#server docker start //CentOS6启动方法
开启docker 远程 服务
开启docker 2375 防火墙端口 firewall-cmd --zone=public -add-port=2375/tcp --permanent
防火墙开放添加8080端口 firewall-cmd --zone=public --add-port=8080/tcp --permanent
刷新防火墙：firewall-cmd --reload
重新启动防火墙 systemctl restart firewalld.service
查看端口是否打开 firewall-cmd --zone= public --query-port=2375/tcp
浏览器访问IP：2375/info 则看到信息说明配置成功。
浏览器访问 http://192.168.1.109:2375/info

docker 使用
1、启动 docker
systemctl start docker
2、关闭docker
systemctl stop docker
3、查看docker的运行状态
systemctl status docker
docker images // 查看docker镜像
docker ps //查看docker容器
4、启动docker 容器
docker start 容器名称
或者 docker start 容器id
5、停止docker 容器
docker stop 容器名称
6、删除
查询服务 ：docker ps
先停止 服务：docker stop xxx
然后删除 服务：docker rm xxxx
在删除 镜像：docker rmi xxx
示例：
[root@localhost my.Shells]# docker images

nginx
启动： service nginx start
快速停止nginx: nginx -s stop
重启 Nginx: nginx -s reopen
修改配置后重新加载生效: nginx -s reload
注意事项：
如果安装好nginx后无法通过浏览器来访问请按照下面的步骤逐一执行
首先检查
nignx -t
然后查看
ps -ef | grep nginx
如果以上都没有问题那就是防火墙的问题
sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload
查看启动的进程： ps -ef | grep xxxx
查看运行情况 : netstat -tnlp
