Oracle 12c 單實例安裝

1、準備工做

實驗環境：Redhat 6.6   Oracle 12c 12.2.0.1

一、官網下載

https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle12c-linux-12201-3608234.html?ssSourceSiteId=otncn

二、安裝所需rpm包

# rpm -q binutils compat-libcap1 gcc-c++ compat-libstdc++-33 gcc gcc-c++e2fsprogs e2fsprogs-libs glibc glibc-devel ksh libaio-devel libaio libgcc libstdc++ libstdc++-devel libxcb libX11 libXau libXi libXtst make net-tools nfs-utils smartmontools sysstat

 所須要鏡像中都包含，因此能夠經過本地yum方式進行安裝

三、建立用戶組

[root@RmanDB tools]# groupadd -g 54321 oinstall
[root@RmanDB tools]# groupadd -g 54322 dba
[root@RmanDB tools]# groupadd -g 54323 oper

四、建立用戶

[root@RmanDB tools]# useradd -u 54321 -g oinstall -G dba,oper oracle

五、建立目錄

mkdir -p /u01/app/oracle/product/12.2.0/db_1
[root@RmanDB tools]# chown -R oracle:oinstall /u01/app
[root@RmanDB tools]# chmod -R 775 /u01/app

六、配置環境變量

 配置oracle用戶

vim .bash_profile
#ORACLE
PATH=$PATH:$HOME/bin
export PATH
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db_1
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/Apache/bin:$PATH
export ORACLE_SID=gnnt1
ORACLE_HOSTNAME=RmanDB
export ORACLE_OWNER=oracle
export ORACLE_TERM=vt100
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export DISPLAY=192.168.10.2:0.0

七、配置內核

注意：配置大於系統數據須要配置更改，不然不須要配置。

vim /etc/sysctl.conf
添加以下配置
#ORACLE

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 6597069766656
kernel.panic_on_oops = 1
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

配置完成 sysctl -p 刷新生效

八、設置進程數和最大會話數

vi /etc/security/limits.conf

添加使用以下設置。
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240

2、安裝過程

一、解壓

[root@RmanDB tools]# mkdir -p /u01/app/tmp [root@RmanDB tools]# chown -R oracle:oinstall /u01/app/tmp [root@RmanDB tools]# chmod -R 775 /u01/app/tmp

將下載的安裝包解壓
[oracle@RmanDB tmp]$ unzip /tools/linuxx64_12201_database.zip

[oracle@RmanDB tmp]$ ll
total 4
drwxr-xr-x. 7 oracle oinstall 4096 Jan 27 2017 database

二、執行安裝

[oracle@RmanDB ~]$ /u01/app/tmp/database/runInstaller
Starting Oracle Universal Installer...

Checking Temp space: must be greater than 500 MB. Actual 175476 MB Passed
Checking swap space: must be greater than 150 MB. Actual 81019 MB Passed

>>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<

Some requirement checks failed. You must fulfill these requirements before

continuing with the installation,

>>> Ignoring required pre-requisite failures. Continuing...

看你的需求選擇是要只安裝數據庫軟件仍是軟件+配置庫

安裝單實例

 

若是檢查出問題，請先解決再行安裝不然可能安裝失敗

等待安裝

使用root用戶執行腳本

[root@RmanDB tmp]# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.

Changing groupname of /u01/app/oraInventory to oinstall.
The execution of the script is complete.



[root@RmanDB tmp]# /u01/app/oracle/product/12.2.0/db_1/root.sh
Performing root user operation.

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u01/app/oracle/product/12.2.0/db_1

Enter the full pathname of the local bin directory: [/usr/local/bin]:
The contents of "dbhome" have not changed. No need to overwrite.
The contents of "oraenv" have not changed. No need to overwrite.
The contents of "coraenv" have not changed. No need to overwrite.

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root script.
Now product-specific root actions will be performed.
Do you want to setup Oracle Trace File Analyzer (TFA) now ? yes|[no] :
