Universal搭建流程之二—LNMP环境搭建之3—docker的安装（前期不用）

一、docker安装

1、下载软件（docker))

sharepoint网站

wget https://download.topunix.com/LNMP/docker/containerd.io-1.2.2-3.el7.x86_64.rpm
wget https://download.topunix.com/LNMP/docker/docker-ce-19.03.0-3.el7.x86_64.rpm
wget https://download.topunix.com/LNMP/docker/docker-ce-cli-19.03.0-3.el7.x86_64.rpm
wget https://download.topunix.com/LNMP/docker/container-selinux-2.119.2-1.911c772.el7_8.noarch.rpm

2、yum安装

yum localinstall -y containerd.io-1.2.2-3.el7.x86_64.rpm
yum localinstall -y container-selinux-2.119.2-1.911c772.el7_8.noarch.rpm
yum localinstall -y docker-ce-cli-19.03.0-3.el7.x86_64.rpm
yum localinstall -y docker-ce-19.03.0-3.el7.x86_64.rpm

3、docker配置

vi /etc/docker/daemon.json

{
"registry-mirrors":["https://docker.mirrors.ustc.edu.cn","https://hub-mirror.c.163.com","https://yrrmmhwn.mirror.aliyuncs.com","https://registry.docker-cn.com","https://3laho3y3.mirror.aliyuncs.com","http://f1361db2.m.daocloud.io","https://mirror.ccs.tencentyun.com"],
"insecure-registries": ["192.168.21.109:8880"],
"max-concurrent-downloads": 20,
"max-concurrent-uploads": 10,
"debug": true,
"data-root": "/data/docker/data",
"log-opts": {
"max-size": "100m",
"max-file": "5"
}
}

4、docker启动

systemctl start docker

4、docker的测试

（1）获取镜像（互联网获取）

# docker pull busybox:1.28.3

--查看当前有哪些版本的busybox

# docker search busybox

（2）查看当前有哪些镜像

# docker images

（3）删除镜像

# docker rmi -f eb1648c027a4

（4）启动一个容器

# docker run -it busybox:1.28.3 /bin/sh  #注：这种方法退出去后就会自动清理。

--后台(d)启动一个容器，退出后，容器继续运行，同时可以给容器起一个名字

$ docker run -itd --name conLLL busybox:1.28.3 /bin/sh

（5）查看容器

# docker ps
# docker ps -l
# docker ps -a    --查看容器,所有容器，在运行的或已经停止的

# docker start 580cbd2fce63

# docker stop 124c050bdf7a
# docker restart 124c050bdf7a

# docker attach conLLL

# docker start conLLL 

# docker exec -it conLLL /bin/sh

$ docker export 124c050bdf7a > busybox.1.28.3.tar

$ docker save busybox:1.28.3 > busybox.1.28.3.tar

$ cat busybox.1.28.3.tar | docker import - fgedu/busybox.1.28.3
$ docker load < busybox.1.28.3.tar

docker rm 580cbd2fce63
docker rm -f 580cbd2fce63   --强制删除

docker container prune

docker logs -f 124c050bdf7a

docker top conLLL

docker inspect conLLL

$ docker port 124c050bdf7a

5000/tcp -> 0.0.0.0:5000
