一、安装docker

yum install -y yum-utils
#配置阿里源
yum-config-manager \
>     --add-repo \
>     https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#更新源
[root@localhost ~]# yum makecache fast -q
#安装docker
[root@localhost ~]# yum install docker-ce docker-ce-cli containerd.io -y -q
#启动docker并开机自启
[root@localhost ~]# systemctl start docker
[root@localhost ~]# systemctl enable docker

二、获取docker的Oracle镜像

docker pull jaspeen/oracle-11g

三、上传Oracle11g安装包

/install目录是默认安装目录，不然安装时会报错（Installation files not found. Unzip installation files into mounted(/install) folder）

#创建Oracle安装目录，
mkdir /install
#将两个Oracle安装目录上传到/install目录下
-rw-r--r--. 1 root root 1239269270 4月  29 15:52 linux.x64_11gR2_database_1of2.zip
-rw-r--r--. 1 root root 1111416131 4月  29 15:54 linux.x64_11gR2_database_2of2.zip
#解压
[root@localhost install]unzip linux.x64_11gR2_database_1of2.zip
[root@localhost install]unzip linux.x64_11gR2_database_2of2.zip

[root@localhost install]# ll
总用量 2295592
drwxr-xr-x. 8 root root        128 8月  21 2009 database
-rw-r--r--. 1 root root 1239269270 4月  29 15:52 linux.x64_11gR2_database_1of2.zip
-rw-r--r--. 1 root root 1111416131 4月  29 15:54 linux.x64_11gR2_database_2of2.zip

四、安装Oracle11g

[root@localhost install]# docker run --privileged --name oracle11g -p 1521:1521 -v /install/:/install jaspeen/oracle-11g

五，初始化数据库

5.1，连接到容器，

docker exec -it oracle11g /bin/bash

3.2，切换到oracle用户，然后连接到sql控制台

su - oracle
sqlplus / as sysdba
#默认scott用户是被锁定的，需要解锁
SQL>
3.3，解锁账户
SQL> alter user scott account unlock;
