1.Docker 安裝

• 卸載舊版本

yum remove docker docker-client \
docker-client-latest  docker-common \
docker-latest  docker-latest-logrotate \
docker-logrotate  docker-selinux \
docker-engine-selinux  docker-engine

• 安裝依賴組件

sudo yum install -y yum-utils \
device-mapper-persistent-data  lvm2

• 添加yum源

sudo yum-config-manager --add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast

• 安裝docker

yum -y install docker-ce

• 啟動(dòng)docker

# 設(shè)置docker開機(jī)自啟動(dòng)
systemctl enable docker     
systemctl start docker

• 驗(yàn)證安裝是否成功

docker version

顯示如下證明安裝啟動(dòng)成功:

• 配置加速器

vi /etc/docker/daemon.json    #修改配置

添加如下配置:

{
    "registry-mirrors": ["https://tueulghe.mirror.aliyuncs.com","https://registry.docker-cn.com","http://hub-mirror.c.163.com","https://docker.mirrors.ustc.edu.cn"]
}

• 開啟docker遠(yuǎn)程訪問

vi /usr/lib/systemd/system/docker.service    #修改docker服務(wù)配置文件

修改如下:

# 在ExecStart=/usr/bin/dockerd 后添加
-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

:wq 保存退出

systemctl daemon-reload      #重新載入配置
systemctl restart docker     #重啟docker

• 開放2375端口

vi /etc/sysconfig/iptables

添加如下規(guī)則

-A INPUT -p tcp -m state --state NEW -m tcp --dport 2375 -j ACCEPT

:wq 保存退出

# 重啟iptables服務(wù)使規(guī)則配置生效
systemctl restart iptables.service 

2.Docker-compose安裝

• 下載docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

• 對(duì)文件添加可執(zhí)行權(quán)限

sudo chmod +x /usr/local/bin/docker-compose

• 驗(yàn)證安裝是否成功

docker-compose --version

顯示如下說明安裝成功:

docker-compose version 1.24.1, build 4667896b
