Linux Redhat 7.9 下 Docker 离线安装部署

Docker安装前要

Docker官网：

服务器版：https://docs.docker.com/engine/install/#server

Docker 离线二进制tgz压缩包下载地址：https://download.docker.com/linux/static/stable/x86_64/

例如下载：docker-23.0.6.tgz

Docker 离线rpm包下载地址：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

Docker离线安装步骤:

1、确定OS系统环境，CentOS 7/Redhat 7及以上版本

# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.9 (Maipo)
# uname -a
Linux vm-ldp-sentry-test 3.10.0-1160.el7.x86_64 #1 SMP Tue Aug 18 14:50:17 EDT 2020 x86_64 x86_64 x86_64 GNU/Linux

2、卸载旧版本

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

3、下载离线安装包，上传至服务端并解压,并将解压后得到的二进制文件全复制到/usr/bin目录下.

# ls -lh
total 12534
drwxrwxr-x  2 1000 1000      146 May  6  2023 docker
-rw-r--r--  1 root root 66999866 May 14 17:09 docker-23.0.6.tgz

# cp docker/* /usr/bin/

4、将docker注册成系统服务,修改 "vi /etc/systemd/system/docker.service" 内容（没有的话vi命令会自动创建该文件）;

     注意:配置需要注意的是 ： ExecStart=/usr/bin/dockerd，代表dockerd所在位置.

# cat  /etc/systemd/system/docker.service
[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 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

5、增加文件可执行权限

# chmod +x /etc/systemd/system/docker.service
# systemctl daemon-reload

6、设置开机自启动

# systemctl enable docker.service
# systemctl status docker.service
##systemctl disable docker.service

7、启动docker服务：

# systemctl start docker
#systemctl stop docker
# systemctl restart docker
