3、docker 安装

3.1 上传解压

[root@docker ~]# rz -E
rz waiting to receive.
[root@docker ~]# ls
anaconda-ks.cfg  docker-18.06.-ce.tgz
[root@docker ~]# tar -xvf docker-18.06.-ce.tgz
docker/
docker/docker-containerd
docker/docker-proxy
docker/docker
docker/docker-runc
docker/dockerd
docker/docker-containerd-ctr
docker/docker-containerd-shim
docker/docker-init
[root@docker ~]# ls docker/
docker                  docker-containerd-shim  docker-proxy
docker-containerd       dockerd                 docker-runc
docker-containerd-ctr   docker-init

3.2 移动解压文件内容至 /usr/bin/ 目录下

[root@docker ~]# cp docker/* /usr/bin/
[root@docker ~]# ls /usr/bin/docker*
/usr/bin/docker                 /usr/bin/docker-containerd-shim  /usr/bin/docker-proxy
/usr/bin/docker-containerd      /usr/bin/dockerd                 /usr/bin/docker-runc
/usr/bin/docker-containerd-ctr  /usr/bin/docker-init

3.3 将 docker 注册为 service

[root@docker ~]# vim /etc/systemd/system/docker.service    #新建文件，将下列配置添加至文件
[Unit]

Description=Docker Application Container Engine

Documentation=https://docs.docker.com

After=network-online.target firewalld.service

Wants=network-online.target

[Service]

Type=notify

# the default is not to use systemd for cgroups because the delegate issues still

# exists and systemd currently does not support the cgroup feature set required

# for containers run by docker

ExecStart=/usr/bin/dockerd

ExecReload=/bin/kill -s HUP $MAINPID

# Having non-zero Limit*s causes performance problems due to accounting overhead

# in the kernel. We recommend using cgroups to do container-local accounting.

LimitNOFILE=infinity

LimitNPROC=infinity

LimitCORE=infinity

# Uncomment TasksMax if your systemd version supports it.

# Only systemd  and above support this version.

#TasksMax=infinity

TimeoutStartSec=

# set delegate yes so that systemd does not reset the cgroups of docker containers

Delegate=yes

# kill only the docker process, not all processes in the cgroup

KillMode=process

# restart the docker process if it exits prematurely

Restart=on-failure

StartLimitBurst=

StartLimitInterval=60s

[Install]

WantedBy=multi-user.target

3.4 启动 docker

[root@docker ~]# chmod +x /etc/systemd/system/docker.service  #添加文件权限
[root@docker ~]# systemctl daemon-reload    #重载unit配置文件
[root@docker ~]# systemctl start docker    /#启动Docker
[root@docker ~]# systemctl enable docker.service    #设置开机自启
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /etc/systemd/system/docker.service.
