Docker 安装Oracle11g (不做持久化)

docker安装oracle11g (不做持久化)

1.下载镜像

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

2.启动oracle

docker run -d -p 1521:1521 --name oracle registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

遇到的问题

iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 1521 -j DNAT --to-destination 172.17.0.2:1521 ! -i docker0: iptables: No chain/target/match by that name

解决方法:

#重启docker
systemctl restart docker

3.查看容器是否启动成功

[oracle@76661f8b8349 ~]$ ss -ntl
State      Recv-Q Send-Q        Local Address:Port          Peer Address:Port 
LISTEN     0      0                        :::35560                   :::*     
LISTEN     0      0                        :::1521                    :::*    
#查看容器
[root@localhost oracle]# docker ps
CONTAINER ID        IMAGE                                                  COMMAND                  CREATED             STATUS              PORTS                    NAMES
76661f8b8349        registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   About an hour ago   Up 56 minutes       0.0.0.0:1521->1521/tcp   oracle

4.进入oralce容器创建用户

[root@localhost oracle]# docker exec -it oracle /bin/bash
[oracle@76661f8b8349 /]$ cd /home/oracle/
[oracle@76661f8b8349 ~]$ source .bash_profile 
[oracle@76661f8b8349 ~]$ 
[oracle@76661f8b8349 ~]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Wed Nov 18 11:10:07 2020

SQL> conn /as sysdba
Connected.
SQL> alter user system identified by system;

User altered.

SQL> alter user sys identified by system;

User altered.

SQL> create user mike identified by mikeops;

User created.

SQL> grant connect,resource,dba to mike;

Grant succeeded.

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

Profile altered.

SQL> alter system set processes=2000 scope=spfile;

System altered.

SQL> select * from dba_users t where t.username = 'MIKE';

其中涉及到的命令含义：

cd /home/oracle # 进入到 oracle 用户目录

source .bash_profile # 加载 oracle 环境变量

sqlplus /nolog # 登录oracle数据库

conn /as sysdba # 切换管理用户

alter user system identified by system; # 修改system用户账号密码为system

alter user sys identified by system; # 修改sys用户账号密码为system

create user mike identified by mikeops; # 创建内部管理员账号mike 密码为mikeops

grant connect,resource,dba to mike; # 将dba权限授权给内部管理员账号

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED; # 修改密码规则策略为密码永不过期

alter system set processes=2000 scope=spfile; # 修改数据库最大连接数据

select * from dba_users t where t.username = ‘MIKE’; # 查看mike用户创建信息* *

5.使用Navicat连接测试

​ (1)创建oracle数据库连接

​ (2)连接名:随便起

​ 连接类型:Basic

​ 主机:数据库所在服务器IP地址

​ 端口:1521

​ 服务名:ORCL

​ 选择SID

     用户名:刚才上面创建的用户名

​ 密码:刚才上面创建用户的密码
