步骤
uname -r 检查内核版本
yum install docker 安装docker
systemctl start docker //启动docker
docker -v //查看版本号
systemctl enable docker //docker开机启动
systemctl stop docker //停止docker
docker search mysql //搜索mysql镜像
docker pull mysql //下载mysql镜像
docker images //查看当前系统中镜像的状态
docker pull mysql:5.5 //5.5版本的镜像
docker rmi 29e0ae3b69b9 删除镜像
tomcat配置步骤
docker search tomcat //搜索镜像
docker pull tomcat //拉去镜像
docker run --name mytomcat -d tomcat:latest //启动容器 后台 版本
docker ps //查看运行中的容器
docker stop 0b09fbd875b0 //停止tomcat容器 容器ID
docker ps -a //查看所有容器
docker start 0b09fbd875b0 //启动容器 容器ID
docker rm 0b09fbd875b0 //先停止容器，然后就可以删除容器了 容器ID
docker run -d -p 8888:8080 tomcat 启动容器
-d表示后台运行
-p表示主机8888端口映射到tomcat的8080端口
这样启动以后，就可以外网:8888查看tomcat了，注意防火墙屏蔽端口
service firewalld status //查看防火墙状态
docker logs c6f0a631a540 //查看容器日志
mysql,redis,rabbitmq,elasticsearch安装步骤
docker pull mysql //下载镜像
docker run --name mysql01 -d mysql //启动容器
这样启动容器并不能正常运行
通过 `docker logs`可以看到说需要设置mysql的密码
有问题的容器，直接`docker rm 78c308e8939f`删除
docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql//启动mysql容器
mysql的root用户密码是123456
由于没有做端口映射，所以也不能访问
docker run -p 3306:3306 --name mysql02 -e MYSQL_ROOT_PASSWORD=123456 -d mysql
端口号映射
root密码
后台运行
