CENTOS7 Installing Oracle 11G

1. Check the system version number:

uname-a

Linux node2 3.10.0-123.el7.x86_64 #1 SMP Mon June 12:09:22 UTC x86_64 x86_64 x86_64 gnu/linux

Cat/etc/redhat-release

#CentOS Linux release 7.0.1406 (Core) Comment out the previous version number

Redhat-7 manually added

2. Create users and Groups

Groupadd Oinstall

Groupadd dba

USERADD-G oinstall-g dba-m Oracle

passwd Oracle

Create home directories, data catalogs, and dictionary directories and authorize

mkdir-p/01/app/oracle/oraclebase

Mkdir/01/app/oracle/oralnventory

Chown-r oracle.oinstall/01/app/oracle/oraclebase/

Chown-r oracle.oinstall/01/app/oracle/oralnventory/

3. Modify the System kernel

cat/etc/sysctl.conf

Net.ipv4.icmp_echo_ignore_broadcasts = 1

Net.ipv4.conf.all.rp_filter = 1

Fs.file-max = 6815744 #设置最大打开文件数

FS.AIO-MAX-NR = 1048576

Kernel.shmall = 2097152 #共享内存的总量, 8G memory setting: 2097152*4k/1024/1024

Kernel.shmmax = 2147483648 #最大共享内存的段大小

Kernel.shmmni = 4096 #整个系统共享内存端的最大数

Kernel.sem = 250 32000 100 128

Net.ipv4.ip_local_port_range = 9000 65500 #可使用的IPv4端口范围

Net.core.rmem_default = 262144

net.core.rmem_max= 4194304

net.core.wmem_default= 262144

net.core.wmem_max= 1048576

Save exit Execute the following command in effect

sysctl-p

4. Limit the number of open files to Oracle user settings

vim +/etc/security/limits.conf Add the following command to the last line of the file

Oracle soft nproc 2047

Oracle Hard Nproc 16384

Oracle Soft Nofile 1024

Oracle Hard Nofie 65535

5. Modify User Environment variables

vim +/home/oracle/.bash_profile

Export oracle_base=/01/app/oracle/#oracle Database installation directory

Export Oracle_home= $ORACLE _base/product/11.2.0/db_1 #oracle数据库路径

Export ORACLE_SID=ORCL #oracle Start DB instance Name

Export Oracle_term=xterm #xterm Window mode installation

Export path= $ORACLE _home/bin:/usr/sbin: $PATH #添加系统环境变量

Export ld_library_path= $ORACLE _home/lib:/lib:/usr/lib #添加系统环境变量

Export #防止安装过程乱码

Export Nls_lang=american_america. ZHS4GBK #设置oracle客户端字符集 must be consistent with the set of character sets at Oracle installation.

Keep exiting after executing the following command:

Source/home/oracle/.bash_profile Immediate effect
