docker 部署Nginx

一、安装 docker

1.从官方下载Docker安装包并上传至虚拟机 https://download.docker.com/linux/static/stable/x86_64/

2.解压安装包 tar -xvf docker-22.0.6.tgz

3.将解压出来的docker文件内容移动到 /usr/bin/ 目录下 mv docker/* /usr/bin/

4.将docker注册为service服务 vi /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.启动docker

chmod +x /etc/systemd/system/docker.service #设置权限
systemctl daemon-reload
systemctl start docker            #启动Docker
systemctl enable docker.service   #设置开机自启

6.验证 systemctl status docker #查看Docker状态

docker -v #查看Docker版本

二、安装 docker-compose

1.获取docker-compose部署文件，官方获取地址如下： https://github.com/docker/compose/releases/docker-compose-Linux-x86_64

2.将上述文件拷贝至服务器某处，然后将其移动到/usr/local/bin，并重命名为“docker-compose” mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose

3.为docker-compose文件赋予可执行权限，命令如下： chmod +x /usr/local/bin/docker-compose

4.查看是否安装成功，命令如下： docker-compose -v
