深圳软件测试培训：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

搜索获得“好评 stars”超过的5个的记录（这个参数的用法已经被废止，不建议使用了）
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
3.docker.io/wordpress latest 5040cbf30a44 2 days ago 502 MB

5.[root@localhost docker]#
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
检查容器运行情况，可以看到新运行的mysql容器
1.[root@localhost /]# docker ps

1.[root@localhost /]# docker run -d --name mywp -e WORDPRESS_DB_HOST=mysql -e WORDPRESS_DB_PASSWORD=1111 -p 80:80 --link wpmysql:mysql wordpress
2.32ad7252ec8e7d0b3fd6abd8a8c4883f2cccdb4480f2994c14ee05b7b8f2dc76
docker run -d
–name mywp 设置容器名称
-e WORDPRESS_DB_PASSWORD=1111 设置访问数据库的密码
-p 80:80 在主机和容器间进行端口映射
–link wpmysql:mysql 连接到mysq容器
wordpress
