【程序源代码】docker精选操作

service network restart

ip addr

1、检查内核版本，必须是3.10及以上
uname -r
2、安装Docker
yum install docker
3、输入y确认安装
4、启动Docker
[root@localhost ~]# systemctl start docker
[root@localhost ~]# docker -v
Docker version 1.12.6, build 3e8e77d/1.12.6
5、开机启动Docker
[root@localhost ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
6、停止Docker
systemctl stop docker

1、搜索镜像
[root@localhost ~]# docker search tomcat
2、拉取镜像
[root@localhost ~]# docker pull tomcat
3、根据镜像启动容器
docker run --name mytomcat -d tomcat:latest
4、docker ps 查看运行中的容器
5、停止运行中的容器
docker stop 容器的id
6、查看所有的容器
docker ps -a
7、启动容器
docker start 容器id
8、删除一个容器
docker rm 容器id
9、启动一个做了端口映射的tomcat
[root@localhost ~]# docker run -d -p 8888:8080 tomcat
docker run --privileged -it -d --name tomcat02 -p 8099:8080 tomcat
-d：后台运行
-p: 将主机的端口映射到容器的一个端口 主机端口:容器内部的端口
10、为了演示简单，关闭Linux的防火墙
service firewalld status；查看防火墙状态
service firewalld stop：关闭防火墙
11、查看容器的日志
docker logs container-name/container-id
更多命令参看https://docs.docker.com/engine/reference/commandline/docker/
可以参考每一个镜像的文档

docker pull mysql

[root@localhost ~]# docker run --name mysql01 -d mysql
42f09819908bb72dd99ae19e792e0a5d03c48638421fa64cce5f8ba0f40f5846
mysql退出了
[root@localhost ~]# docker ps -a

//错误日志
[root@localhost ~]# docker logs 42f09819908b
error: database is uninitialized and password option is not specified 
You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD；这三个参数必须指定一个

[root@localhost ~]# docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql
b874c56bec49fb43024b3805ab51e9097da779f2f572c22c695305dedd684c5f
[root@localhost ~]# docker ps

[root@localhost ~]# docker run -p 3306:3306 --name mysql02 -e MYSQL_ROOT_PASSWORD=123456 -d mysql

docker run --name mysql03 -v /conf/mysql:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag
把主机的/conf/mysql文件夹挂载到 mysqldocker容器的/etc/mysql/conf.d文件夹里面
改mysql的配置文件就只需要把mysql配置文件放在自定义的文件夹下（/conf/mysql）
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
指定mysql的一些配置参数
