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-2.23.52.0.1-12.el7.x86_64 
compat-libcap1-1.10-3.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++-33 compat-libstdc++-33*i686 compat-libstdc++-33*.devel compat-libstdc++-33 compat-libstdc++-33*.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

 

8.设置oracle密码

passwd oracle

 

9.验证创建及所属组是否正确：id oracle

[root@docker ~]# id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)

 

 

10.配置内核参数

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

# system default settings live in /usr/lib/sysctl.d/00-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(5) and sysctl.d(5).
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 7516192768 #7g
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

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*80%*80%，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“4294967295/1024/1024/1024=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

 

11.修改用户权限

vim  /etc/security/limits.conf

#在末尾添加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240

 

12.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

 

13.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 16384
       ulimit -n 65536
    else
       ulimit -u 16384 -n 65536
   fi
fi

使之生效：source /etc/profile

source /etc/profile

 

14.创建安装目录

mkdir -p /u01/app/
chown -r oracle:oinstall /u01/app/
chmod -r 775 /u01/app/

 

15.配置环境变量

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

export oracle_base=/u01/app/oracle
export oracle_sid=dbsrv2

使之生效

source ~/.bash_profile

 

16.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

 

17.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

 

18.设置响应文件权限

[oracle@docker ~]$ su - root

[root@docker ~]# chmod 700 /home/oracle/etc/*.rsp

 

19.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/11.2.0/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=81920 //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）

 

20.开始静默安装

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

 

21.查看安装日志

tail -f /u01/app/orainventory/logs/installactions2016-08-31_06-56-29pm.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

22.使用root用户执行脚本

su - root
/u01/app/orainventory/orainstroot.sh
/u01/app/oracle/product/11.2.0/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

23.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=$oracle_home/lib:/usr/lib
export oracle_home=/u01/app/oracle/product/11.2.0/db_1
export path=$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'

 

24.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.
oracle net services configuration:

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

[oracle@docker ~]$ lsnrctl start

26.静默dbca建库，编辑应答文件

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

[createdatabase]
gdbname = "dbsrv2"

# /etc/security/limits.conf
#
#each line describes a limit for a user in the form:
#<domain>        <type>  <item>  <value>
#where:
#<domain> can be:
#        - a user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax,
#                 for maxlogin limit
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#<item> can be one of the following:
#        - core - limits the core file size (kb)
#        - data - max data size (kb)
#        - fsize - maximum filesize (kb)
#        - memlock - max locked-in-memory address space (kb)
#        - nofile - max number of open file descriptors
#        - rss - max resident set size (kb)
#        - stack - max stack size (kb)
#        - cpu - max cpu time (min)
#        - nproc - max number of processes
#        - as - address space limit (kb)
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by posix message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#<domain>      <type>  <item>         <value>
