CentOS 7 的环境为
$ uname -a
Linux oracle 3.10.0-123.13.1.el7.x86_64 #1 SMP Tue Dec 9 23:06:09 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
注意安装的时候需要安装一个桌面系统(X-Windows + KDE 或者 Gnome),否则安装程序无法运行。
然后根据需要修改共享内存等等系统参数。这个也不写了,网上有很多。不过据我的测试,CentOS7貌似不需要修改也是可以的,Oracle在进行安装检查的时候没有报告问题(和以前的不一样)。当然为了调优数据库的性能,还是修改的好。
安装gcc,因为后面Oracle link的时候会用到
yum install gcc
安装结果为
[plain] view plaincopy
gcc --version
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-16)

(这里注意,因为Oracle需要的3.4和安装的4.8的参数的区别,后面link会失败,解决方法见后)
1. 下载,需要下载两个文件
p10404530_112030_Linux-x86-64_1of7.zip
p10404530_112030_Linux-x86-64_2of7.zip
2. 解压缩,把这两个文件解压到同一个目录下
3. 运行installer。中间依赖检查那一步,可以Skip。因为Oracle要检查是否安装了gcc,glibc等等比较老的版本(3.4)
4. 前面一切顺利。到了Link那一步,出错了。Log显示
error in invoking target 'agent nmhs'
在网上查到了解决方案:
[plain] view plaincopy
vi $ORACLE_HOME/sysman/lib/ins_emagent.mk
Search for the line
$(MK_EMAGENT_NMECTL)
Change it to:
$(MK_EMAGENT_NMECTL) -lnnz11
5. Retry重试。这就OK了。
6. 之后就没啥问题了。正常安装,执行root脚本,等等。
7. 安装后重启服务器。
8. 重启后,检查oracle用户的环境变量:
[plain] view plaincopy
declare -x ORACLE_HOME="/home/oracle/app/oracle/proct/11.2.0/dbhome_1"
declare -x ORACLE_SID="orcl"
9. 进入$ORACLE_HOME/network/admin,检查listener.ora:
[plain] view plaincopy
[oracle@oracle admin]$ cat listener.ora
# listener.ora Network Configuration File: /home/oracle/app/oracle/proct/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = /home/oracle/app/oracle/proct/11.2.0/dbhome_1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.16.33.212)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /home/oracle/app/oracle
重点检查其中的SID,HOST,PORT,ORACLE_HOME是否正确。如果不正确客户端会报告ERROR-ORA-12514:TNS:监听程序当前无法识别连接描述符中请求的服务 错误。
如果没有问题,进入$ORACLE_HOME/bin,启动*:
[plain] view plaincopy
[oracle@oracle bin]$ ./lsnrctl

启动正常,使用sqlplus启动数据库:
[plain] view plaincopy
[oracle@oracle bin]$ ./sqlplus '/ as sysdba'
SQL> startup
ORACLE instance started.

10. Centos7自带了SELINUX,关掉
11. Centos7自带了下一代防火墙firewalld,关掉,否则客户端连接过来会报TNS Timeout异常
[plain] view plaincopy
[root@oracle ~]# service firewalld stop
Redirecting to /bin/systemctl stop firewalld.service
现在其它机器就应该可以正常连接并使用Oracle了。
另:装Oracle最省事的还是在Oracle自己的Enterprise Linux上安装。那些依赖,系统参数,等等等都不需要设置了。
