一、安装Docker软件二、创建CentOS7.6的容器三、rpm方式安装Oracle 19c3.1、安装database-preinstall包3.2、下载安装db软件，上传到docker容器内3.3、创建数据库实例四、数据库配置4.1、修改密码4.2、修改参数4.3、修改EM的展现方式4.4、配置用户环境变量五、重启容器后的操作六、将容器打包成镜像上传，供其他用户使用七、其他用户下载使用
一、安装Docker软件
11、卸载掉旧版本的 Docker：
2yum remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine
3
42、执行以下安装命令去安装依赖包：
5yum install -y yum-utils device-mapper-persistent-data lvm2
6yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
7
8yum -y install docker-ce docker-ce-cli containerd.io
9
10# 若执行报错，则配置yum源
11wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
12wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
13
14或一键安装：
15curl -fsSL get.docker.com -o get-docker.sh
16sh get-docker.sh
17
18
19systemctl start docker
20systemctl status docker
21
22
233、检查版本
24docker version
25docker info
二、创建CentOS7.6的容器
1https://hub.docker.com/_/centos?tab=tags
2
3--拉取镜像
4docker pull centos:7.6.1810
5
6--创建容器
7docker run -d --name lhr2019ocp -h lhr2019ocp -p 5500-5510:5500-5510 -p 1521:1521 -p 222:22 --privileged=true centos:7.6.1810 /usr/sbin/init
8
9--修改时区
10docker cp /usr/share/zoneinfo/Asia/Shanghai lhr2019ocp:/etc/localtime
11
12--进入容器
13docker exec -it lhr2019ocp /bin/bash
14
15--安装一些必要的系统包
16yum install -y openssh-clients openssh-server initscripts net-tools telnet which wget passwd e4fsprogs lrzsz sudo unzip lvm2 tree traceroute bridge-utils dos2unix rlwrap
17yum -y install vim redhat-lsb
18
19--解决agetty进程cpu占用率100%，宿主机和容器都需要执行
20systemctl stop getty@tty1.service
21systemctl mask getty@tty1.service
22
23--启动ssh进程
24systemctl restart sshd
25--修改root用户密码
26echo "root:lhr" | chpasswd
27
28--远程登录
29ssh root@192.168.1.35 -p222
30
31-- 配置容器内的yum源：阿里云
32wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
33wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
34
35yum clean all
36rpm --rebuilddb
以上命令执行完后，就可以通过笔记本的cmd直接连接到容器内，注意端口的映射关系：
三、rpm方式安装Oracle 19c
3.1、安装database-preinstall包
1yum -y install oracle-database-preinstall-19c
1yum install -y https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
具体地址可以打开https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/index.html
1[root@lhr2019ocp /]# yum install -y https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

安装过程中会安装系统依赖包，等安装完成后，就会创建orale用户和组，也会修改系统参数，详见目录：/var/log/oracle-database-preinstall-19c/results。
3.2、下载安装db软件，上传到docker容器内
下载db 19c的地址：https://www.oracle.com/database/technologies/oracle-database-software-downloads.html安装19c数据库软件：
1yum install -y oracle-database-ee-19c-1.0-1.x86_64.rpm

26Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user.
四、数据库配置
4.1、修改密码
1alter user sys identified by lhr;
4.2、修改参数
1alter system set sga_max_size=1g scope=spfile;

3alter system set pga_aggregate_target=100m;
4startup force
4.3、修改EM的展现方式
1##切换为Flash-based的EM Express
2SQL> @?/rdbms/admin/execemx emx
3##切换为Java JET的EM Express
4SQL> @?/rdbms/admin/execemx omx
1https://192.168.1.35:5500/em
4.4、配置用户环境变量
1cat >> /home/oracle/.bash_profile << "EOF"
2
3export ORACLE_SID=ORCLCDB
4export ORACLE_BASE=/opt/oracle
