docker安装_docker ce.tgz

centos7-linux安装docker(离线方式) - 青阳闲云 - 博客园

1.下载docker的安装文件

Index of linux/static/stable/x86_64/

下载的是：docker-18.06.3-ce.tgz 这个压缩文件

2.将docker-18.06.3-ce.tgz文件上传到centos7-linux系统上，用ftp工具上传即可

3.解压：

[root@localhost java]# tar -zxvf docker-18.06.3-ce.tgz

 4.将解压出来的docker文件复制到 /usr/bin/ 目录下：

[root@localhost java]# cp docker/* /usr/bin/

5.进入/etc/systemd/system/目录,并创建docker.service文件

[root@localhost java]# cd /etc/systemd/system/

[root@localhost system]# touch docker.service

6.打开docker.service文件,将以下内容复制

[root@localhost system]# vi docker.service

注意： --insecure-registry=192.168.200.128 此处改为你自己服务器ip

[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 --selinux-enabled=false --insecure-registry=192.168.200.128 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 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # 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=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target

7.给docker.service文件添加执行权限

[root@localhost system]# chmod 777 /etc/systemd/system/docker.service

8.重新加载配置文件（每次有修改docker.service文件时都要重新加载下）

[root@localhost system]# systemctl daemon-reload

9.启动

[root@localhost system]# systemctl start docker

10.设置开机启动

[root@localhost system]# systemctl enable docker.service

11.查看docker状态

[root@localhost system]# systemctl status docker

12.配置镜像加速器,默认是到国外拉取镜像速度慢,可以配置国内的镜像如：阿里、网易等等。下面配置一下网易的镜像加速器。打开docker的配置文件: /etc/docker/daemon.json文件：

[root@localhost docker]# vi /etc/docker/daemon.json

配置如下:

{"registry-mirrors": ["http://hub-mirror.c.163.com"]}

配置完后:wq保存配置并重启docker 一定要重启不然加速是不会生效的！！！

[root@localhost docker]# service docker restart
