ORACLE12C Enterprise Edition 64-bit

Process Summary:

2. Root Install Dependency Package:

   Install binutils compat-libcap1 compat-libstdc++-compat-libstdc++-makesysstat UnixODBC unixodbc*.i686 Unixodbc-devel unixodbc-devel*.i686 libxp 

4. To set up users and groups:

6. Groupadd oinstall  groupadd dba  groupadd Oper useradd-g  oinstall-g dba,oper Oracle  "  123456passwd--stdin Oracle #oracle用户的登录密码, follow-up login to use, remember. 

8. To create the installation directory:

10. Mkdir-p/orcl/app/oracle/product/12.1.  0/db_1  chown-r oracle:oinstall/orcl/775/orcl/app    

12. To modify the kernel parameter vi/etc/sysctl.conf, add:

13. FS.AIO-MAX-NR =1048576Fs.File-max =6815744Kernel.shmall =2097152 Kernel.shmmax = 1200000000  Kernel.shmmni = 4096 Kernel.sem = 250 32000 100 Span style= "COLOR: #800080" >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     

15. One argument: the above Kernel.shmmax = 1200000000 may be problematic and can be changed to 4098955264. I have a warning when I install it, but when I choose to ignore it, the installation will work.

17. After the change, make it effective: sysctl-p

19. Change file limit: vi/etc/security/limits.conf, add:

20. 2047  16384  1024x76865536     

    As well as Vi/etc/pam.d/login, add:

    Session Required Pam_limits.so

    To modify Ulimit:vi/etc/profile, add:

    "Oraclethen  "/bin/kshthen16384 ulimit-else     

Modify environment variables. VI ~oracle/.bash_profile, add:

oracle_base=/orcl/app/Oracle  oracle_home= $ORACLE _base/product/12.1.  0/db_1  oracle_sid=orcl  export oracle_base oracle_home oracle_sid  
#如果已经存在PATH, simply follow the path followed by: $oracle_home . PATH= $ORACLE _home/bin: $PATH  export PATH  

Download and install the JDK RPM-IVH jdk-8u101-linux-x64.rpm. Java-version.

Restart reboot.

Because I installed the smallest installation, there is no graphical interface, so here to install the X Window graphical interface.

    # yum check-update    "X window System"

#yum Install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts

Restart reboot.

After logging into the system, execute init 5 to the graphical interface, open the terminal and execute the following command

# SU- oracle  /orcl/app/Oracle  $ unzip linuxamd64_12102_database_se2_1of2.zip  $ unzip Linuxamd64_12102_database_se2_2of2.zip  $ export LANG="en_us"  / orcl/app/oracle/Database  $.

A graphical interface appears and is installed according to your needs.

Start Oracle

#su- Oracle #切换到 Oracle users and switch to its environment $lsnrctl status #查看监听及数据库状态 $lsnrctl start #启动监听$startup #启动服务

Log in and create a namespace, user, table.
