软件测试：Docker下部署MySQL和Wordpress
检查当前系统版本，Docker要求CentOS必须是64位7版本以上才可以：
1.[root@localhost ~]# cat /etc/redhat-release
2.CentOS Linux release 7.6.1810 (Core)
检查内核版本，Docker支持内核3.10版本以上：
1.[root@localhost ~]# uname -r
2.3.10.0-957.el7.x86_64
安装Docker
1.[root@localhost ~]# yum install -y docker
为了加快Docker的下载速度，我们一般从国内镜像站点下载。修改镜像服务器
打开配置文件
1.[root@localhost ~]# cd /etc/docker
2.[root@localhost docker]# vi daemon.json
修改配置文件内容，此处选择阿里云的镜像站点：
1.{
2. “registry-mirrors”: [“https://6xacs6l2.mirror.aliyuncs.com”]
3.}
启动Docker服务
1.[root@localhost docker]# systemctl start docker.service
查看安装的Docker版本
1.[root@localhost docker]# docker -v
2.Docker version 1.13.1, build 7f2769b/1.13.1
查看当前已有的镜像（新建系统镜像为空）
1.[root@localhost docker]# docker images
2.REPOSITORY TAG IMAGE ID CREATED SIZE
搜索全部与wordpress有关的镜像
1.[root@localhost docker]# docker search wordpress

1.[root@localhost docker]# docker search wordpress -s 5
2.Flag –stars has been deprecated, use –filter=stars=3 instead

查看当前容器列表，已经出现我们拉取的两个镜像文件了：
1.[root@localhost docker]# docker images
2.REPOSITORY TAG IMAGE ID CREATED SIZE

创建并运行MySQL容器
1.[root@localhost /]# docker run -d –privileged=true -p 3306:3306 –name wpmysql -v /data/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=1111 mysql
2.cd13f4311f8e14511eba7d124a0a3a17a4ee553ccdfb4b45770535396c035256
3.[root@localhost /]#
docker run -d
–privileged=true 使container内的root拥有真正的root权限
-p 3306:3306 将主机和容器之间进行端口映射
–name wpmysql 为容器起名
-v /data/mysql:/var/lib/mysql 将mysql挂载到本地主机
-e MYSQL_ROOT_PASSWORD=1111 设置mysql数据库root用户的密码
mysql
