Linux7静默安装Oracle11g教程，亲测实用有效！

1.查看swap大小，若小于150M，需添加增加虚拟空间

dd if=/dev/zero of=/swapadd bs=1024 count=2006424
mkswap /swapadd
swapon /swapadd
重启系统虚拟空间会消失，除非打开/etc/fstab文件，加入
/swap swap swap default 0 0

2.查看操作系统信息

[root@docker ~]# uname -m
x86_64
[root@docker ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)

3.安装前的准备

a.修改主机名，linux7以上系统用：hostnamectl set-hostname hostname

 4.关闭selinux：vi /etc/selinux/config，设置如下，重启系统reboot；

 5.检查以下服务是否安装

binutils-2.23.52.0.-.el7.x86_64

若担心系统包比较旧可考虑先更新程序包：yum -y upgrade，（提示：等待时间比较长！）

用yum进行安装所需服务：

yum -y install binutils compat-libcap1 compat-libstdc++- compat-libstdc++-*i686 compat-libstdc++-*.devel compat-libstdc++- compat-libstdc++-*.devel gcc gcc-c++ glibc glibc*.i686 glibc-devel glibc-devel*.i686 ksh libaio libaio*.i686 libaio-devel libaio-devel*.devel libgcc libgcc*.i686 libstdc++ libstdc++*.i686 libstdc++-devel libstdc++-devel*.devel libXi libXi*.i686 libXtst libXtst*.i686 make sysstat unixODBC unixODBC*.i686 unixODBC-devel unixODBC-devel*.i686

检查31个包是否都有安装，版本号只能大于规定的版本，不能小于

rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst  make sysstat  unixODBC unixODBC-devel

 6.创建oinstall和dba组

/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba

 7.创建Oracle用户：

/usr/sbin/useradd -g oinstall -G dba oracle

设置oracle密码

passwd oracle

验证创建及所属组是否正确：id oracle

[root@docker ~]# id oracle
uid=(oracle) gid=(oinstall) groups=(oinstall),(dba)

8.配置内核参数

[root@docker ~]# vim /etc/sysctl.conf 

# System default settings live in /usr/lib/sysctl.d/-system.conf.
# To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file
#
# For more information, see sysctl.conf() and sysctl.d().
fs.aio-max-nr =
fs.file-max =
kernel.shmall =
kernel.shmmax = 7516192768 #7G
kernel.shmmni =
kernel.sem =
net.ipv4.ip_local_port_range =
net.core.rmem_default =
net.core.rmem_max =
net.core.wmem_default =
net.core.wmem_max = 

参数的值不能小于上面的配置，因为这是oracle官方建议的最小值，所以生产环境建议调整为这些参数，以优化系统性能。

注意：kernel.shmmax的值，#最低：536870912，最大值：比物理内存小1个字节的值，建议比物理内存小一点点就可以（过小的话后期会导致数据库实例无法启动或无法监听）

参数解释：

shmmax=物理内存*%*%，单位是字节
kernel.shmmax：表示单个共享内存段的最大值，以字节为单位，此值一般为物理内存的一半，不过大一点也没关系，这里设定的为4GB，即“///=4G”。
kernel.shmmin：表示单个共享内存段的最小值，默认为1byte
kernel.shmall：表示整个系统范围内可用共享内存页的总量，单位是页（page），在32位系统上一页等于4kB，也就是4096字节。计算公式是：shmmax/PAGE_SIZE
kernel.shmmni：表示整个系统范围内内存段的最大数量，一般为4096.
ip_local_port_range  ：表示端口的范围。在监听器帮助客户端进程和服务器进程建立连接时，会用到指定范围内的端口。
kernel.sem  ：表示设置的信号量，这4个参数内容大小固定。
net.core.rmem_default  ：表示接收套接字缓冲区大小的缺省值（以字节为单位）。
net.core.rmem_max  ：表示接收套接字缓冲区大小的最大值（以字节为单位）
net.core.wmem_default  ：表示发送套接字缓冲区大小的缺省值（以字节为单位）。
net.core.wmem_max  ：表示发送套接字缓冲区大小的最大值（以字节为单位）。

参数解释

修改后使之生效

/sbin/sysctl -p

 9.修改用户权限

vim  /etc/security/limits.conf

#在末尾添加
oracle soft nproc
oracle hard nproc
oracle soft nofile
oracle hard nofile
oracle soft stack
oracle hard stack 

 10.在/etc/pam.d/login 文件中，使用文本编辑器或vi命令增加或修改以下内容

session required /lib64/security/pam_limits.so
session required pam_limits.so

 11.在/etc/profile 文件中，使用文本编辑器或vi命令增加或修改以下内容

if [ $USER = "oracle" ]; then
   if [ $SHELL = "/bin/ksh" ]; then
       ulimit -p
       ulimit -n
    else
       ulimit -u  -n
   fi
fi

使之生效：source /etc/profile

source /etc/profile

 12.创建安装目录

mkdir -p /data/oracle/app/
chown -R oracle:oinstall /data/oracle/app/
chmod -R  /data/oracle/app/

#提示：图型化界面安装需创建 oraInventory目录

mkdir -p /data/oracle oraInventory
chown -R oracle:oinstall /data/oraInventory
chmod -R  /data/oraInventory

 13.配置环境变量

[oracle@docker ~]$ vim ~/.bash_profile 

export ORACLE_BASE=/data/app/oracle
export ORACLE_SID=dbsrv2

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

PATH=$PATH:$ORACLE_HOME/bin

使之生效

source ~/.bash_profile

 14.解压oracle软件

[root@docker src]# unzip linux.x64_11gR2_database_1of2.zip
[root@docker src]# unzip linux.x64_11gR2_database_2of2.zip

 15.切换到Oracle用户，复制响应文件模板

[oracle@docker ~]$ mkdir etc
[oracle@docker ~]$ cp  /usr/local/src/database/response/* /home/oracle/etc/
[oracle@docker ~]$ ls etc
dbca.rsp  db_install.rsp  netca.rsp

 16.设置响应文件权限

[oracle@docker ~]$ su - root

[root@docker ~]# chmod  /home/oracle/etc/*.rsp

 17.切换到oracle用户：su - oracle，修改安装Oracle软件的响应文件/home/oracle/etc/db_install.rsp

oracle.install.option=INSTALL_DB_SWONLY     // 安装类型
ORACLE_HOSTNAME=docker        // 主机名称（hostname查询）
UNIX_GROUP_NAME=oinstall     // 安装组
INVENTORY_LOCATION=/u01/app/oraInventory   //INVENTORY目录（不填就是默认值）
SELECTED_LANGUAGES=en,zh_CN,zh_TW // 选择语言
ORACLE_HOME=/u01/app/oracle/product/11.2./db_1    //oracle_home
ORACLE_BASE=/u01/app/oracle     //oracle_base
oracle.install.db.InstallEdition=EE 　　　　// oracle版本
oracle.install.db.EEOptionsSelection=false 　　//自定义安装，否，使用默认组件
oracle.install.db.DBA_GROUP=dba /　　/ dba用户组
oracle.install.db.OPER_GROUP=oinstall // oper用户组
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE //数据库类型
oracle.install.db.config.starterdb.globalDBName=orcl //globalDBName
oracle.install.db.config.starterdb.SID=dbsrv2      //SID
oracle.install.db.config.starterdb.memoryLimit= //自动管理内存的内存(M)
oracle.install.db.config.starterdb.password.ALL=oracle //设定所有数据库用户使用同一个密码
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false         //（手动写了false）
DECLINE_SECURITY_UPDATES=true 　　//设置安全更新（貌似是有bug，这个一定要选true，否则会无限提醒邮件地址有问题，终止安装。PS：不管地址对不对）

 18.开始静默安装

[oracle@docker database]$ /data/software//database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp

19.查看安装日志

tail -f /u01/app/oraInventory/logs/installActions2016--31_06--29PM.log

出现如下提示表示安装完成

[oracle@zyadmin ~]$ /data/software//database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp

请查看 '/data/u01/app/oraInventory/logs/silentInstall2018-08-18_03-29-11PM.log' 以获取详细资料。

以 root 用户的身份执行以下脚本:
    . /data/u01/app/oraInventory/orainstRoot.sh
    . /data/u01/app/oracle/product/11.2./db_1/root.sh

Successfully Setup Software.

 20.使用root用户执行脚本

su - root
/u01/app/oraInventory/orainstRoot.sh
/u01/app/oracle/product/11.2./db_1/root.sh

常见报错解决办法：

（1）若没有生成orainstRoot.sh这个文件，解决办法：删除/etc/oraInst.loc文件

（2） 若重装Oracle提示：“系统标识符（SID）已经存在，请指定另一个SID”，

解决办法：把/etc/oratab里面对应的记录注释或者删除掉

(3)修改Oracle端口：

a.查看监听状态，停止监听

$lsnrctl status

$lsnrctl stop

b.修改配置文件

$vi $ORACLE_HOME/network/admin/listener.ora

(修改对应的端口为欲更改端口)

c.登陆并查看local_listener参数

$sqlplus / as sysdba

>show parameter local_listener

(此时value值是空的)

d.修改local_listener参数

>alter system set local_listener="(address=(protocol=tcp)(host=172.16.8.129)(port=1521))";

 （host后面加主机名或者IP，然后就可以查看local_listener参数了）

e.启动监听，查看状态

>lsnrctl start

>lsnrctl status

f.防火墙端口开放

# /sbin/iptables -l INPUT -p tcp --dport 端口 -j ACCEPT

# /etc/rc.d/init.d/iptables save

a.查看监听状态，停止监听

$lsnrctl status

$lsnrctl stop

b.修改配置文件

$vi $ORACLE_HOME/network/admin/listener.ora

(修改对应的端口为欲更改端口)

c.登陆并查看local_listener参数

$sqlplus / as sysdba

>show parameter local_listener

(此时value值是空的)

d.修改local_listener参数

>alter system set local_listener="(address=(protocol=tcp)(host=172.16.8.129)(port=1521))";

（host后面加主机名或者IP，然后就可以查看local_listener参数了）

e.启动监听，查看状态

>lsnrctl start

>lsnrctl status

f.防火墙端口开放

# /sbin/iptables -l INPUT -p tcp --dport 端口 -j ACCEPT

# /etc/rc.d/init.d/iptables save

 21.增加或修改oracle的环境变量

su  - oracle
vim ~/.bash_profile
#for oracle
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=dbsrv2
export ROACLE_PID=ora11g
#export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export ORACLE_HOME=/u01/app/oracle/product/11.2./db_1
export PATH=$PATH:$ORACLE_HOME/bin

export LANG="zh_CN.UTF-8"
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.AL32UTF8"
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'

 22.配置监听程序：netca /silent /responsefile /home/oracle/etc/netca.rsp

[oracle@docker ~]$ netca /silent /responsefile /home/oracle/etc/netca.rsp

Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /home/oracle/etc/netca.rsp
Done parsing command line arguments.

23.启动监听程序：[oracle@docker ~]$ lsnrctl start

[oracle@docker ~]$ lsnrctl start

 24.静默dbca建库，编辑应答文件

[oracle@docker ~]$ vi etc/dbca.rsp

RESPONSEFILE_VERSION = "11.2.0"
OPERATION_TYPE = "createDatabase"
[CREATEDATABASE]
GDBNAME = "dbsrv2"

TEMPLATENAME = "General_Purpose.dbc"
CHARACTERSET = "AL32UTF8"

 25.建库：

[oracle@docker ~]$ dbca -silent -responseFile etc/dbca.rsp

[oracle@docker ~]$ dbca -silent -responseFile etc/dbca.rsp

Enter SYS user password:
