docker 安裝oracle 19C
最近有個需求，客戶環境安裝oracle資料庫安裝不上，想到用docker的方式制作好oracle鏡像然後傳到客戶的機器上直接用docker跑oracle下面是大概流程記錄一下
安裝oracle19cdocker的版本必須在17以上
Docker version is below the minimum required version 17.09
Please upgrade your Docker installation to proceed.
解除安裝原來yum安裝的docker
systemctl stop docker.service
yum remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine
安裝docker
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum -y install docker-ce docker-ce-cli containerd.io

2. 将安裝包拷貝到該目錄下，運作開始安裝：
需要提前下載下傳Oracle安裝媒體，檔案名預設是不需要更改的，應該是LINUX.X64_193000_db_home.zip，然後将其複制到對應版本的目錄下即可。

注意：/oracle/oradata目錄權限一定要正确，在容器中oracle使用者的uid是54321，是以要保證容器内的oracle使用者有權限讀寫該目錄。
如建立oracle使用者且uid是54321：
容器内的使用者id如下
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba)

echo "oracle" | passwd --stdin oracle
chown oracle:oinstall /data/oracle
useradd -u 54321 -g oinstall -G dba oracle
注:如果"DATABASE IS READY TO USE!"提示資訊，表示資料庫已成功安裝了。
注意:oracle 企業版的docker run的指令格式如下（XE版的都有所差別）：
