CentOS 7 (with Red Hat) installs Oracle 11g R2 the most complete and fine tips

Prospect:

1. Install the x86_64 version of the CentOS 7 system (or the corresponding version of Red Hat, etc.) to the GNOME Desktop edition.

2. Download and install and activate Xmanager Enterprise 5 for connection access to Linux systems, data transfer, etc.

3. Download the unpacked Oracle 11g R2 for Linux package and place the [Database/stage/components/oracle.jdk/1.5.0.17.0/1/datafiles/all.jar] Add the folder [fallback] and put the file [Simsun.ttf] in.

Ps. This step is used to solve the garbled problem of installing Oracle in the Chinese state, or to try to modify the environment variables.

To install Oracle:

Step One: Pre-installation configuration and Deployment 1. Configure the IP address of the server

A. Configuring a fixed IP address for Linux through the Network Connections section

B. Configure [/etc/hosts], edit by the VI editor, add the relevant information of fixed IP, as follows:

　　　　　　

[[email protected] ~]# vi/etc/hosts// Add IP address information at the end of the file//such as: 192.168.3.222 Oracle 11g

2. Turn off the network firewall and SELinux

Go to root.

Turn off disable firewall:

 [[email protected] ~]# Systemctl status Firewalld.service//active:active (running) since six 2016-08-27 08:54:09 CST; 18min ago//# Systemctl stop Firewalld.service// close firewall [[email protected] ~]# Systemctl status Firewalld.service// Check the running status of the firewall again active:inactive (dead) since six 2016-08-27 09:15:16 CST; 10s ago[[email protected] ~] # systemctl disable Firewalld.service// disable Firewall//. Omit                 

Turn off SELinux disabled

[[Email protected] ~]#vi/etc/selinux/config/*#This file controls the state of the SELinux on the system.# selinux= can take one of the these three values:# Enforcing-selinux security policy is enforced.  # Permissive-selinux Prints warnings instead of enforcing. # Disabled-no SELinux policy is loaded.  selinux=disabled//Here instead of disabled # selinuxtype= can take one of the three the values:# targeted-targeted PR Ocesses is protected,# Minimum-modification of targeted policy. Only selected processes is protected. # Mls-multi level Security protection. Selinuxtype=targeted*/               

Restart Linux,root under reboot.

3. Create a running user and user group

[[Email protected] ~] # Groupadd oinstall[[email protected] ~]# Groupadd dba[[email protected] ~]# useradd-g Oinstall- G dba-m Oracle[[email protected] ~]# passwd Oracle changes the user's password for Oracle. New Password: Invalid password: password is not checked by dictionary- it re-enters the new password based on the dictionary word: passwd: All authentication tokens have been successfully updated. [[Email protected] ~] # ID oracleuid=1001 (Oracle) gid=1001 (oinstall) group =1001 (Oinstall), 1002(DBA) [[email protected] ~]  

4. Create the relevant directory for the Oracle database installation

A. Creating an Oracle-related directory

*/ora/oracle installation directory

*/ORA/ORAINV Configuration file Directory

*/ora/database installation file storage location Directory

[[Email protected] ~] # CD/[[email protected]/]# mkdir-p/ora/oracle[[email protected]/]# Mkdir-p/ora/orainv[[emai L protected]/]# mkdir-p/ora/database[[email protected]/]# CD ora[[email protected] ora]# LS -L Total Consumptiondrwxr-xr-x 4 root root 4096 August 09:34 databasedrwxr-xr-x 2 root root 4096 August 09:32 oracledrwxr -xr-x 2 root root 4096 August 09:33 orainv[[email protected] ora]        

B. xftp Oracle 11g for Linux files into the top database folder of Linux

Ps. [All.jar] files described in [forward-looking. 3] can be uploaded directly here.

C. Add permissions and change everyone for the above directory

[[email protected]/] # Chown-r oracle:oinstall/ora[[email protected]/]# ls-l// Change the owner of the Ora folder and its sub-files to Oracle and the user group to Oinstall [[email protected]/] # chmod 777-r Ora[[email protected]/]# ls-l//Modify the permissions for the Ora and its sub-files for readable writable executables       

5. Check the Linux Software environment package

by Rpm-qa | grep * (package name) for inspection

[[Email protected] ~]#rpm-qa binutils compat compat-libstdc gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc+ +-devel libxi libxtst make Sysstat unixODBC nixodbc-devel/*binutils-2.23.52.0.1-12.

Installation of packages that are not installed can be found in the ISO file (files can be placed in the root folder).

[Email protected] ~]# RPM-IVH *.rpm

6. Modify the configuration file

A. vi/etc/sysctl.conf

[[Email protected] ~] # VI  /etc/sysctl.conf/*fs.aio-max-nr = 1048576Fs.file-max = 6815744Kernel.shmall = 2097152 Kernel.shmmax = 4294967295Kernel.shmmni = 4096Kernel.sem = 32000 [Net.ipv4.ip_local_port_] Range = 9000 65500net.core.rmem_default = 262144Net.core.rmem_max = 4194304Net.core.wmem_default = 262144Net.core.wmem_max = 1048576*/            

B. vi/etc/security/limits.conf

[[Email protected] ~] # vi/etc/security/limits.conf/*Oracle Soft nproc 2047Oracle hard nproc 16384Oracle Soft nofile 1024< C7>oracle hard Nofile 65536*/     

C. vi /etc/pam.d/login

[[Email protected] ~] # vi/etc/pam.d/login/*session required/lib/security/pam_limits.sosession required PAM_ limits.so*/   

D. vi /etc/profile

[[Email protected] ~] # vi/etc/profile/*"Oracle" ]; Then"/bin/ksh" ]; Thenulimit-p 16384ulimit-n 65536elseulimit-u 16384-n 65536fifi*/     

E. Configuring environment variables

[Email protected] ~]# vi/home/oracle/.bash_profile/*export oracle_base=/ora/oracleexport oracle_home= $ORACLE _base/product/11.2.0/db_1export oracle_sid=orclexport oracle_term=xtermexport PATH=$ Oracle_home/bin:/usr/sbin:$PATHexport ld_library_path=$ORACLE _home/lib:/lib:/usr/lib//export lang=cexport nls_lang=American_america. zhs16gbk*/             

Step Two: Installation of Oracle

1. Log in with Oracle user, CD to database directory

2../runinstaller Enter the installer
