八、安裝

一、系統準備

VMware Workstation12

Centos 7.5

Oracle 12.2.0.1

Grid 12.2.0.1（可選）也可將資料放置在普通磁碟上

二、系統設定

1、防火牆

firewall-cmd --zone=public --add-port=1521/tcp --permanent
firewall-cmd --zone=public --add-port=5500/tcp --permanent
firewall-cmd --zone=public --add-port=5502/tcp --permanent
firewall-cmd --reload
 

注：1521為oracle例項預設埠，5500是EM https預設埠，5502為EM的http埠，都可以自定義

2、SELINUX設定

vim /etc/selinux/config
修改內容：
SELINUX=disabled

3、主機名

hostnamectl set-hostname oratest
vim /etc/hosts
新增內容：
192.168.10.176 oratest

4、logind設定

vim /etc/systemd/logind.conf
修改內容：
RemoveIPC=no

systemctl daemon-reload
systemctl restart systemd-logind
 

三、安裝軟體包

1、oracleasm

用來配置asm的磁碟，如果將oracle資料檔案放置在普通磁碟上，則略過。

wget http://public-yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracleasm-support-2.1.11-2.el7.x86_64.rpm
wget http://download.oracle.com/otn_software/asmlib/oracleasmlib-2.0.12-1.el7.x86_64.rpm
yum install -y kmod-oracleasm
rpm -ivh oracleasmlib-2.0.12-1.el7.x86_64.rpm oracleasm-support-2.1.11-2.el7.x86_64.rpm
 

2、oracle依賴包

yum install -y binutils compat-libcap1 compat-libstdc++-33.i686 compat-libstdc++-33.x86_64 gcc gcc-c++ glibc.i686 glibc.x86_64 glibc-devel.i686 glibc-devel.x86_64 ksh libgcc.i686 libgcc.x86_64 libstdc++.i686 libstdc++.x86_64 libstdc++-devel.i686 libstdc++-devel.x86_64 libaio.i686 libaio.x86_64 libaio-devel.i686 libaio-devel.x86_64 make sysstat elfutils-libelf-devel

四、建立目錄、組、使用者

1、建立目錄

mkdir -p /u01/12.2.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle 
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01

2、建立使用者

groupadd oinstall
groupadd dba
groupadd asmdba
groupadd asmadmin
groupadd asmoper
groupadd oper
groupadd backupdba
groupadd dgdba
groupadd kmdba
useradd -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid
useradd -g oinstall -G dba,asmdba,oper,backupdba,dgdba,kmdba oracle
#設定使用者密碼
passwd grid
passwd oracle

3、設定環境變數

vim /home/grid/.bash_profile
export NLS_LANG=AMERICAN_AMERICA.UTF8
export LANG=en_US.UTF-8
export ORACLE_HOME=/u01/12.2.0/grid
export ORACLE_SID=+ASM
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin/
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

vim /home/oracle/.bash_profile
export NLS_LANG=AMERICAN_AMERICA.UTF8
export LANG=en_US.UTF-8
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/dbhome_1
export ORACLE_SID=orcl
export ORACLE_TERM=xterm
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin/
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

五、配置核心引數

vim /etc/pam.d/login
session required pam_limits.so

vim /etc/security/limits.conf
oracle soft nproc 16384
oracle hard nproc 16384 
oracle soft nofile 1024 
oracle hard nofile 65536
oracle  soft  stack  10240
oracle  hard stack  32768
grid   soft   nofile    1024
grid   hard   nofile    65536
grid   soft   nproc    16384
grid   hard   nproc    16384
grid   soft   stack    10240
grid   hard   stack    32768

vim /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967296
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
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 = 1048586

vim /etc/fstab 
tmpfs                   /dev/shm                tmpfs   defaults,size=12G        0 0
tmpfs                   /run                    tmpfs   defaults,size=12G        0 0
tmpfs                  /sys/fs/cgroup           tmpfs   defaults,size=12G        0 0

六、配置ASM屬性

oracleasm configure -i
Default user to own the driver interface []: grid
Default group to own the driver interface []: oinstall
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done

七、建立分割槽

注：在做以下步驟前可先重啟伺服器，使前面的設定生效

#重啟
reboot
#檢視磁碟
fdisk -l
#分割槽/dev/sdb1,/dev/sdc1, /dev/sdd1
fdisk /dev/sdb
oracleasm createdisk myasm01 /dev/sdb1
oracleasm createdisk myasm02 /dev/sdc1
oracleasm createdisk myasm03 /dev/sdd1
oracleasm scandisks
oracleasm listdisks

八、安裝

1、安裝grid（可選）

通過OUI安裝，略過

2、安裝oracle

通過OUI安裝，略過

九、啟動關閉

注：先關資料庫，後關asm。先啟asm，後啟資料庫

1、資料庫

oracle>sqlplus / as sysdba
shutdown immediate       #關閉
startup                  #啟動

2、ASM

grid>sqlplus / as sysasm
shutdown immediate
startup

3、通過srvctl啟停

srvctl start|stop|enable asm
srvctl start|stop database -db orcl

4、EM

oracle>sqlplus / as sysdba

#啟動
exec DBMS_XDB_CONFIG.SETHTTPPORT(5502);
exec DBMS_XDB_CONFIG.SETHTTPSPORT(5500);
#關閉
exec DBMS_XDB_CONFIG.SETHTTPSPORT(0);
exec DBMS_XDB_CONFIG.SETHTTPPORT(0);
#檢視埠
SELECT dbms_xdb_config.gethttpsport FROM DUAL;
SELECT dbms_xdb_config.gethttpport FROM DUAL;
