Docker 安装 MySQL
方法一、通过 Dockerfile构建
创建Dockerfile
首先，创建目录mysql,用于存放后面的相关东西。
|
w3cschool@w3cschool:~$
mkdir -p ~/tomcat
/webapps ~/tomcat/logs
~/tomcat/conf |
data目录将映射为mysql容器配置的数据文件存放路径
logs目录将映射为mysql容器的日志目录
conf目录里的配置文件将映射为mysql容器的配置文件
进入创建的mysql目录，创建Dockerfile

# Tomcat Native 1.2+ requires a newer version
of OpenSSL than debian:jessie has available
(1.0.2g+)

EXPOSE 8080
CMD ["catalina.sh", "run"] |
通过Dockerfile创建一个镜像，替换成你自己的名字
|
w3cschool@w3cschool:~/tomcat$
docker build -t tomcat . |
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
|
w3cschool@w3cschool:~/tomcat$
docker images|grep tomcat
tomcat latest 70f819d3d2d9 7 days ago 335.8
MB |
方法二、docker pull mysql
查找Docker Hub上的mysql镜像
这里我们拉取官方的镜像,标签为5.6
|
w3cschool@w3cschool:~/tomcat$
docker pull tomcat |
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为mysql,标签为5.6的镜像。
使用mysql镜像
运行容器
|
w3cschool@w3cschool:~/tomcat$
docker run
--name tomcat
-p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test
-d tomcat
acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d5248
81267aa715c61cf75320
w3cschool@w3cschool:~/tomcat$ |
命令说明：
1.-p 3306:3306：将容器的3306端口映射到主机的3306端口
2.-v $PWD/conf/my.cnf:/etc/mysql/my.cnf：将主机当前目录下的conf/my.cnf挂载到容器的/etc/mysql/my.cnf
3.-v $PWD/logs:/logs：将主机当前目录下的logs目录挂载到容器的/logs
4.-v $PWD/data:/mysql_data：将主机当前目录下的data目录挂载到容器的/mysql_data
5.-e MYSQL_ROOT_PASSWORD=123456：初始化root用户的密码
查看容器启动情况
|
w3cschool@w3cschool:~/tomcat$
docker ps
CONTAINER ID IMAGE COMMAND ... PORTS NAMES
acb33fcb4beb tomcat "catalina.sh run"
...
