ORACLE 12C

step1：安裝必需的rpm包

yum install binutils libX11 compat-libcap1 libXau compat-libstdc++-33 libaio gcc libaio-devel gcc-c++ libdmx glibc-devel glibc ksh make libgcc sysstat libstdc++ xorg-x11-utils libstdc++-devel xorg-x11-xauth libXext libXv libXtst libXi libxcb libXt libXmu libXxf86misc libXxf86dga libXxf86vm nfs-utils smartmontools

step2：修改內(nèi)核參數(shù)

vim /etc/sysctl.d/98-oracle-kernel.conf

vm.swappiness = 1

vm.dirty_background_ratio = 3

vm.dirty_ratio = 80

vm.dirty_expire_centisecs = 500

vm.dirty_writeback_centisecs = 100

kernel.sem = 250 32000 100 128

fs.aio-max-nr = 1048576

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

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 8589934590  ==8G，大于SGA即可

kernel.shmall = 2147483648     ==8G

kernel.shmmni = 4096

sysctl -p /etc/sysctl.d/98-oracle-kernel.conf

step3：設(shè)置用戶限制

vim /etc/security/limits.d/99-grid-oracle-limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

oracle hard stack 32768

step4：添加用戶

groupadd --gid 54321 oinstall

groupadd --gid 54322 dba

groupadd --gid 54326 oper

groupadd --gid 54327 backupdba

groupadd --gid 54328 dgdba

groupadd --gid 54329 kmdba

useradd --uid 54321 --gid oinstall --groups dba,oper,backupdba,dgdba,kmdba oracle

echo "oracle"|passwd --stdin oracle

step5：設(shè)置目錄

mkdir -p /u01/app/12.2.0/grid

chown -R oracle.oinstall /u01

chmod -R 755 /u01

step6：設(shè)置環(huán)境變量

su - oracle

vim .bash_profile

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1

export ORACLE_SID=orcl

export PATH=$ORACLE_HOME/bin:$PATH; 

step7：開(kāi)始安裝

su - root

xhost +

su - oracle

[oracle@oracle12c database]$ ./runInstaller

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2018-08-11_01-14-29AM. Please wait ...

DISPLAY not set. Please set the DISPLAY and try again.

Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:

- For csh:              % setenv DISPLAY 192.168.1.128:0.0

- For sh, ksh and bash:     $ DISPLAY=192.168.1.128:0.0; export DISPLAY

Use the following command to see what shell is being used:

    echo $SHELL

Use the following command to view the current DISPLAY environment variable setting:

    echo $DISPLAY

- Make sure that client users are authorized to connect to the X Server.

To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:

% xhost +

To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock':

    %

If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.

Typical path for xclock: /usr/X11R6/bin/xclock

之后嘗試設(shè)置了多次$DISPLAY，都不行，如下

DISPLAY=192.168.107.155:0.0;export $DISPLAY

DISPLAY=192.168.107.155:1.0;export $DISPLAY

DISPLAY=192.168.107.155:0.1export $DISPLAY

DISPLAY=:0;export $DISPLAY

DISPLAY=:1;export $DISPLAY

之后我在root的一個(gè)窗口執(zhí)行xclock，發(fā)現(xiàn)沒(méi)有clock，之后安裝了xorg-x11-apps(yum install xorg-x11-apps)，使用root的xclock就可以看到clock了

之后su - oracle還是看不到clock

之后到root窗口echo $DISPLAY發(fā)現(xiàn)是:0，所以我在oracle窗口也設(shè)置

    DISPLAY=:0;export $DISPLAY

之后就可以正常的圖形化安裝了

安裝過(guò)程截圖：

這里用fix來(lái)修復(fù)一下

忽略swap報(bào)警，我這里只給swap分了1G

step8：DBCA建庫(kù)

在這里你可以選擇典型配置，也可以選擇自定義配置，我選擇的是自定義(advanced configuration)

創(chuàng)建listner，叫l(wèi)istner1

給SGA分6G，pga 500M，這是測(cè)試庫(kù)，就我一個(gè)人用
