一、离线安装部署 docker
1、检查docker ps
[root@CAIP122 ~]# docker ps
-bash: docker: command not found
2、下载docker 二进制包
https://docs.docker.com/engine/install/binaries/
下载到本机
[root@CAIP122 opt]# ls
docker-19.03.9.tgz
3、解压
[root@CAIP122 opt]# tar -xvf docker-19.03.9.tgz
复制文件到/bin目录
[root@CAIP122 opt]# ls
docker docker-19.03.9.tgz
[root@CAIP122 opt]# cp docker/* /usr/bin/
4、编辑离线安装配置文件
[root@CAIP122 opt]# vim /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

# 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

# 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、配置启动项
[root@CAIP122 opt]# chmod +x /etc/systemd/system/docker.service
[root@CAIP122 opt]# systemctl daemon-reload
[root@CAIP122 opt]# systemctl start docker
[root@CAIP122 opt]# systemctl enable docker.service
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /etc/systemd/system/docker.service.
检查状态和版本
[root@CAIP122 opt]# systemctl status docker.service

Status: Downloaded newer image for mysql:5.7
docker.io/library/mysql:5.7
检查镜像
[root@CAIP122 opt]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql 5.7 262701d58edd 6 days ago 495MB
3、启动容器
[root@CAIP122 opt]# docker run -d -p 3310:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 --name mysql mysql:5.7
ae921ec10632f332817aac2059f4da11bc23f5fccf1be4aaf4a7e6daa09b908d
# docker run -p 对外暴露的端口:mysql运行端口 --name 容器名称 -e MYSQL_ROOT_PASSWORD=mysql连接密码 -d 镜像名:版本号
# -p 对外暴露的端口:mysql运行端口 例：3310:3306
# --name 容器名称 //镜像首次启动时会自动创建容器,需要给容器命名
# -e MYSQL_ROOT_PASSWORD=mysql连接密码 //mysql镜像容器创建时必须设置连接密码,否则无法创建容器
# -d 后台运行
检查容器
[root@CAIP122 opt]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ae921ec10632 mysql:5.7 "docker-entrypoint.s…" 4 minutes ago Up 4 minutes 33060/tcp, 0.0.0.0:3310->3306/tcp mysql
4、进入容器exec
[root@CAIP122 opt]# docker exec -it mysql bash
bash-4.2#
#mysql为容器名 或容器ID缩写也可例ae921ec10632
5、在容器内连接mysql
bash-4.2# mysql -uroot -p
Enter password:

4 rows in set (0.00 sec)
6、不进入容器连接mysql测试
[root@CAIP122 opt]# mysql -h127.0.0.1 -uroot -P3310 -p
Enter password:

不进入容器，需要加上IP和映射端口3310，通过 root 和密码 123456 访问 MySQL 服务。
7、启动成功，用Navicat 测试连接
Navicat 连接到服务器3310， 3310和容器内的3306映射 就可以连接上了
测试连接
8、Docker查看日志
[root@CAIP122 opt]# docker logs mysql
#监控日志
[root@CAIP122 opt]# tailf /var/log/mysqld.log
