lsnrctl status // 查看linux系统oracle的监听状态
lsnrctl start // 启动linux系统oracle的监听状态

sqlplus /nolog // 连接oracle的 sqlplus

用 NETCA 建立 listener 时，会自动建立 listener.ora

用 DBCA 也可以创建数据库实例，生成tnsname.ora

配置环境变量 cd ~

[~]vim .bash_profile

---------------------

sqlplus / as sysdba

conn /as sysdba // 使用超级管理员连接 sqlplus

startup
启动、关闭oracle服务命令
net start OracleServiceORCL
net stop OracleServiceORCL

CentOS7.4下安装Oracle 11gR2

https://blog.csdn.net/qq_32786873/article/details/82110235

Centos7安装Oracle 11gR2

https://www.cnblogs.com/startnow/p/7580865.html

平台：CentOS 6.10 x64 带图形
配置4G 4核心cpu 200G硬盘

第一步、安装依赖

yum install -y binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel make sysstat unixODBC-devel pdksh

卸载openjdk

yum remove -y java-1.8.0-openjdk java-1.8.0-openjdk-headless

下载java rpm包，安装Oracle java

[root@o1 ~]# rpm -ivh jdk-8u121-linux-x64.rpm
Preparing... ########################################### [100%]
1:jdk1.8.0_121 ########################################### [100%]

第二步、创建所需用户和组

创建oracle用户并设置密码

[root@o1 ~]# useradd oracle
[root@o1 ~]# passwd oracle

创建用户组

[root@o1 ~]# groupadd oinstall
[root@o1 ~]# groupadd dba

修改oracle用户组

usermod -g oinstall -G dba oracle

第三步、修改内核参数

追加一段内核参数

[root@o1 ~]# vim /etc/sysctl.conf
........
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

执行生效
[root@o1 ~]# sysctl -p

修改文件打开限制，追加一段

[root@o1 ~]# vim /etc/security/limits.conf
.......
oracle soft nproc 4096
oracle hard nproc 65536
oracle soft nofile 4096
oracle hard nofile 65536

创建oracle安装目录

[root@o1 ~]# mkdir -p /u01/app/
[root@o1 ~]# chown -R oracle:oinstall /u01/app/
[root@o1 ~]# chmod -R 775 /u01/app/

重启服务器，使limit生效

第四步、添加环境变量，准备安装

使用oracle用户登陆

[root@o1 ~]# su - oracle
[oracle@o1 ~]$ vim .bash_profile
#追加下面这段
ORACLE_BASE=/u01/app/oracle
ORACLE_SID=sales
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_BASE ORACLE_SID ORACLE_HOME
PATH=$ORACLE_HOME/bin:$PATH

检查主机名能访问不

[oracle@o1 ~]$ ping o1
PING o1 (192.168.1.18) 56(84) bytes of data.
64 bytes from o1 (192.168.1.18): icmp_seq=1 ttl=64 time=0.061 ms

检查正常

解压oracle安装包

[oracle@o1 ~]$ unzip linux.x64_11gR2_database_1of2.zip
[oracle@o1 ~]$ unzip linux.x64_11gR2_database_2of2.zip

第五步、开始安装

进入安装目录，开始安装
静默安装命令，主要配置在db.rsp里面，这个文件可以通过图形安装程序生成，可以从 https://www.linuxidc.com/Linux/2018-08/153802.htm 找到

编辑db.rsp,找到这里设置密码 oracle.install.db.config.starterdb.password.ALL=密码

[oracle@o1 ~]$ cd database/
[oracle@o1 ~]$ ./runInstaller

-ignorePrereq -silent -responseFile /usr/local/database/db.rsp

安装过程需要个几分钟吧

安装成功，提示要执行两个脚本，使用root执行

[root@o1 ~]# sh /u01/app/oraInventory/orainstRoot.sh
[root@o1 ~]# sh /u01/app/oracle/product/11.2.0/dbhome_1/root.sh

完成

基于Linux安装过Oracle的童鞋们都应该清楚,安装Oracle的确是一件比较费时费力的差事，因为仅仅是前期的rpm包，内核参数，创建用户等等这些个步骤都让那些新手不免眼花缭乱，一不留神，就导致最终的安装过程中报错而不得不从头来过。现在基于Oracle Linux，Oracle仅仅需要通过安装oracle-rdbms-server-11gR2-preinstall RPM包即可全部搞定其余未安装的RPM包，解决之间的依赖关系，配置内核参数等等。客官，正在基于Oracle Linux 安装Oralce 11g？那就接着往下看。

1、oracle-rdbms-server-11gR2-preinstall RPM 软件包的功能

a、 Automatically downloading and installing any additional software packages and specific package versions needed for installing Oracle Grid Infrastructure and Oracle Database 12 c Release 1 (12.1) or 11g Release 2 (11.2.0.3), with package dependencies resolved via yum or up2date capabilities.

b、Creating the user oracle and the groups oinstall (for OraInventory) and dba (for OSDBA), which are used during database installation. (For security purposes, this user has no password by default and cannot log in remotely. To enable remote login, please set a password using the passwd tool.)

c、Modifying kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on.

d、Setting hard and soft shell resource limits in /etc/security/limits.conf, such as the locked-in memory address space, the number of open files, the number of processes, and core file size.

e、Setting numa=off in the kernel for x86_64 machines.

2、操作步骤
a、确保网络畅通，即可连接到Internet。
b、已经安装了yum包管理工具。
c、切换到目录 /etc/yum.repos.d/
d、获取配置文件并进行相应修改wget http://public-yum.oracle.com/public-yum-ol6.repo(所需安装版本项下字段enabled=0更改为enabled=1)
e、使用yum安装oracle-rdbms-server-11gR2-preinstall包(oracle-rdbms-server-11gR2-preinstall)
f、校验内核修改日志及原文件备份情况

3、实战演习
a、检查网络环境，确保网络畅通
[root@oel63 ~]# cat /etc/issue
Oracle Linux Server release 6.3
Kernel \r on an \m
[root@oel63 ~]# ping www.baidu.com
PING www.a.shifen.com (115.239.211.110) 56(84) bytes of data.
64 bytes from 115.239.211.110: icmp_seq=1 ttl=54 time=39.2 ms
64 bytes from 115.239.211.110: icmp_seq=2 ttl=54 time=42.2 ms

b、检查yum是否已安装
[root@oel63 ~]# rpm -qa | grep yum
yum-utils-1.1.30-14.el6.noarch
PackageKit-yum-plugin-0.5.8-20.0.1.el6.x86_64

PackageKit-yum-0.5.8-20.0.1.el6.x86_64
yum-metadata-parser-1.1.2-16.el6.x86_64

c、切换到目录 /etc/yum.repos.d/
[root@oel63 ~]# cd /etc/yum.repos.d/

d、获取配置文件并进行相应修改
[root@oel63 yum.repos.d]# wget http://public-yum.oracle.com/public-yum-ol6.repo
