Linux下 安装Docker

使用官方安装脚本自动安装

安装命令如下：

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

也可以使用国内 daocloud 一键安装命令：

curl -sSL https://get.daocloud.io/docker | sh

Docker离线安装

一、Docker安装

1. 安装包官方地址：https://download.docker.com/linux/static/stable/x86_64/

可以先下载到本地，然后通过ftp工具上传到服务器上，或者在服务器上使用命令下载

wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz

2. 解压

tar -zxvf docker-18.06.3-ce.tgz

3. 将解压出来的docker文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/

4. 创建docker.service文件

进入 /etc/systemd/system/ 目录,并创建 docker.service 文件，内容如下，这样可以将docker注册为service服务

[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=127.0.0.1
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

# 此处的–insecure-registry=127.0.0.1（此处改成你私服ip）设置是针对有搭建了自己私服Harbor时允许docker进行不安全的访问，否则访问将会被拒绝。

5. 启动docker

# 给docker.service文件添加执行权限
chmod +x /etc/systemd/system/docker.service
# 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）
systemctl daemon-reload
# 启动
systemctl start docker
# 设置开机启动
systemctl enable docker.service
# 查看docker服务状态
[root@localhost system]# systemctl status docker

二、docker-compose安装

# docker-compose下载并放到/usr/local/bin/下面：
curl -L "https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 下载好docker-compose的前提下，拷贝到指定位置
sudo cp docker-compose /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
docker-compose -v
# 最后使用 docker-compose -v 命令测试是否安装成功（如果提示“没有那个文件或目录”可以重启下服务器再试试）

问题

一、centOS7安装docker遇到 [Errno 14] curl#35 - "TCP connection reset by peer问题解决：

安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

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

1、更换为阿里源

首先这个问题是因为国内访问不到docker官方镜像的缘故，所以我们要使用 国内的源来访问，之前我也试过163的源，但是一直解决不了，但是后来换了阿里源就成功解决了这个问题，不扯淡了直接出语句：

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

成功的话会有如下提示：

repo saved to /etc/yum.repos.d/docker-ce.repo

2、查看docker仓库中的所有版本 输入指令可以看到docker的版本信息，如下：（如果内核版本低，docker版本高会安装出错）

yum list docker-ce --showduplicates | sort -r 

我们可以安装指定版本，使用 sudo yum install ，这里我使用 sudo yum install docker-ce 默认安装最高的版本。例如

sudo yum install docker-ce.x86_64 3:24.0.2-1.el7

3、启动并加入开机启动

sudo systemctl start docker && sudo systemctl enable docker

4、检测是否安装docker成功，查看版本信息。出现如下图，恭喜docker安装成功！可以看到Client与Server的信息。

docker version
sudo docker run hello-world

二、因为之前已经安装过旧版本的docker，在安装的时候报错如下：

Transaction check error:
  file /usr/bin/docker from install of docker-ce-17.12.0.ce-1.el7.centos.x86_64 conflicts with file from package docker-common-2:1.12.6-68.gitec8512b.el7.centos.x86_64
  file /usr/bin/docker-containerd from install of docker-ce-17.12.0.ce-1.el7.centos.x86_64 conflicts with file from package docker-common-2:1.12.6-68.gitec8512b.el7.centos.x86_64
  file /usr/bin/docker-containerd-shim from install of docker-ce-17.12.0.ce-1.el7.centos.x86_64 conflicts with file from package docker-common-2:1.12.6-68.gitec8512b.el7.centos.x86_64
  file /usr/bin/dockerd from install of docker-ce-17.12.0.ce-1.el7.centos.x86_64 conflicts with file from package docker-common-2:1.12.6-68.gitec8512b.el7.centos.x86_64

卸载旧版本的包

$ sudo yum erase docker-common-2:1.12.6-68.gitec8512b.el7.centos.x86_64

再次安装docker

$ sudo yum install docker-ce

三、No Presto metadata available for docker-ce-stable

yum install docker-ce -y

四、Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

yum provides '*/applydeltarpm'  
yum install deltarpm -y

DOCKER COMPOSE

sudo curl -L "https://github.com/docker/compose/releases/download/1.28.0-rc1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version

docker-compose up / docker-compose up -d 起服务（要有docker-compose.yml）
docker start nginx
docker-compose stop

问题：

dlopen: /lib64/libc.so.6: version `GLIBC_2.28’ not found

错误提示意思是没有GLIBC_2.28版本，升级版本：

1、下载 glibc-2./28.tar.gz (随意一个目录)

wget https://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz

2.解压编译等操作（用 root 全权操作，最后两步用时比较久）

[root@hadoop101 opt]# tar -zxvf glibc-2.28.tar.gz
[root@hadoop101 opt]# cd glibc-2.28
[root@hadoop101 glibc-2.28]# mkdir build
[root@hadoop101 glibc-2.28]# cd build
[root@hadoop101 build]# ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
[root@hadoop101 build]# make -j 8
[root@hadoop101 build]# make  install

如果报错：

These critical programs are missing or too old: make bison compiler

查看bison版本：

bison -V

使用 yum 安装bison

yum install -y bison

之后再升级make：
先在 ~/.bash_profile 里加上 PATH=$HOME/local/bin:$PATH

source ~/.bash_profile
ln -s $HOME/local/bin/make $HOME/local/bin/gmake

先下载：

wget https://ftp.gnu.org/gnu/make/make-4.3.tar.gz
tar -zvxf make-4.3.tar.gz
cd make-4.3
./configure --prefix=$HOME/local
make && make install 

3.查看安装结果

[root@hadoop101 build]$ strings /lib64/libc.so.6 | grep GLIBC  (或用这个命令也可以直接查看当前版本：ldd --version)
