安装Oracle数据库

1.搜索oracle镜像

docker search oracle

[root@localhost ~]# docker search oracle

2.拉取阿里云oracle镜像

docker pull registry.aliyuncs.com/helowin/oracle_11g 或者 docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

[root@localhost ~]# docker pull registry.aliyuncs.com/helowin/oracle_11g
Using default tag: latest
latest: Pulling from helowin/oracle_11g
ed5542b8e0e1: Already exists
a3ed95caeb02: Already exists
1e8f80d0799e: Already exists
Digest: sha256:4c12b98372dfcbaafcd9564a37c8d91456090a5c6fb07a4ec18270c9d9ef9726
Status: Image is up to date for registry.aliyuncs.com/helowin/oracle_11g:latest
registry.aliyuncs.com/helowin/oracle_11g:latest

3.查看镜像拉取情况

docker iamges

[root@localhost ~]# docker images
REPOSITORY                                             TAG          IMAGE ID       CREATED       SIZE
...
registry.aliyuncs.com/helowin/oracle_11g               latest       3fa112fd3642   5 years ago   6.85GB

4.创建并启动oracle容器

持久化启动方式：docker run  -itd -p 1521:1521 --name oracle_11g --restart=always -v /mnt/oracle_data/app:/opt/oracle/app -v /mnt/oracle_data/dpdump:/opt/oracle/dpdump  -v  /mnt/oracle_data/oraInventory:/opt/oracle/oraInventory registry.aliyuncs.com/helowin/oracle_11g

5.查看创建的oracle本地数据映射目录

在创建启动oracle容器的时候会自动在宿主机上创建相关的数据映射目录。

[root@localhost ~]# ll /mnt/oracle_data/
总用量 0
drwxr-xr-x. 2 root root 6 2月   9 23:12 app
drwxr-xr-x. 2 root root 6 2月   9 23:12 dpdump
drwxr-xr-x. 2 root root 6 2月   9 23:12 oraInventory

6.查看进程与启动状态

[root@localhost ~]# netstat -antulp
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:1521            0.0.0.0:*               LISTEN      35497/docker-proxy
......[root@localhost ~]# ss -antulp | grep :1521
tcp    LISTEN     0      128       *:1521                  *:*                   users:(("docker-proxy",pid=35497,fd=4))[root@localhost ~]# docker ps
CONTAINER ID   IMAGE                                      COMMAND                  CREATED        STATUS        PORTS                    NAMES
3edfba76f476   registry.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home/o…"   42 hours ago   Up 42 hours   0.0.0.0:1521->1521/tcp   oracle_11g

7.以退出不中断容器的方式进入容器

[root@localhost ~]# docker exec -it oracle_11g bash
[oracle@3edfba76f476 /]$

8.配置容器内环境变量

[root@localhost ~]# docker exec -it oracle_11g bash1.切换为root用户# 密码默认为 helowin
[oracle@3edfba76f476 /]$ su root
Password:                                2.添加环境变量
[root@3edfba76f476 /]# vi /etc/profile
...61 export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_263 export ORACLE_SID=helowin65 export PATH=$ORACLE_HOME/bin:$PATH
...3.使配置生效
[root@3edfba76f476 /]# source  /etc/profile4.创建软链接
[root@3edfba76f476 /]# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin

9.操作oracle

1.切换回oracle用户
[root@3edfba76f476 /]# su - oracle2.登录sqlplus
[oracle@3edfba76f476 ~]$ sqlplus /nologSQL*Plus: Release 11.2.0.1.0 Production on Sat Jan 30 16:32:18 2021Copyright (c) 1982, 2009, Oracle.  All rights reserved.SQL> conn /as sysdba;
Connected.3.修改sys、system用户密码
SQL> alter user system identified by 123456;SQL> alter user sys identified by 123456;SQL> alter profile default limit PASSWORD_LIFE_TIME UNLIMITED;4.创建用户
SQL> create user root identified by 123456;SQL> grant connect,resource,dba to root;SQL> show user;      # 查看当前用户
USER is "SYS"SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

10.查看oracle实例状态

lsnrctl status

[oracle@434bcfed5c5d ~]$ lsnrctl statusLSNRCTL for Linux: Version 11.2.0.1.0 - Production on 09-FEB-2022 23:37:27Copyright (c) 1991, 2009, Oracle.  All rights reserved.Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
STATUS of the LISTENER

The command completed successfully

注意：外部工具连接数据库时，需要配置开放防火墙相应端口。若是阿里云，则需要开放安全组。

11.使用工具连接oracle容器

配置好的oracle容器可以commit成新的镜像，方便以后直接启动运行；也可以把commit的新镜像save导出，方便其他机器load导入镜像直接使用！
