centos7.3上安裝oracle11.2.4RAC

環境：centos7.3、oracle11.2.4、配置了yum倉庫服務10.64.39.210、配置了ntp服務器10.64.39.138

直接獲取腳本初始化系統配置oracle基礎依賴

chmod -R 775  /u01/oracle/product/11.2.4/db_1

3、asm、grid、oracle安裝

1、執行oracle-csh.txt  
 上面執行了
2、安裝依賴包
yum -y install binutils compat-libcap1 compat-libstdc* gcc gcc-c++* glibc glibc-devel ksh libgcc libstdc libaio libaio-devel make elfutils-libelf-devel sysstat

3、配置主機名稱和hosts 配置ssh 互通
hostnamectl set-hostname lsrkzyk1
hostnamectl set-hostname lsrkzyk2

cat <<EOF >> /etc/hosts

#pub
80.128.0.202     lsrkzyk1  
80.128.0.203     lsrkzyk2

EOF

su - grid

ssh-copy-id grid@80.128.0.203

ssh grid@80.128.0.202 date

ssh oracle@80.128.0.202 date
ssh oracle@80.128.0.203 date

ssh oracle@lsrkzyk1 date
ssh oracle@lsrkzyk2 date

ssh oracle@lsrkzyk1p date
ssh oracle@lsrkzyk2p date


5、配置grid 環境變量 和 oracle 環境變量
su - grid
vi .bash_profile

ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_BASE=/u01/grid_base; export ORACLE_BASE
ORACLE_HOME=/u01/grid/11.2; export ORACLE_HOME
GRID_HOME=/u01/grid/11.2; export GRID_HOME
THREADS_FLAG=native; export THREADS_FLAG
PATH=$ORACLE_HOME/bin:$PATH; export PATH
export LANG=en_us.UTF-8


su - oracle
vi .bash_profile

ORACLE_BASE=/u01/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.4/db_1; export ORACLE_HOME
ORACLE_SID=lsrkzyk1; export ORACLE_SID
export ORACLE_UNQNAME=msrkzyk
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
export LANG=en_us.UTF-8


當rac2節點配置完畢以后，修改oracle 、grid用戶下的環境變量:

[root@node2 network-scripts]# vi /home/oracle/.bash_profile

將ORACLE_SID=snrk1 改為ORACLE_SID=snrk2

[root@node2 network-scripts]# vi /home/grid/.bash_profile

將ORACLE_SID=+ASM1 改為ORACLE_SID=+ASM2

統統設置完成后，建議重啟一下第2 個節點。



---------asmlib方法一

6、安置oracle ASMlib  配置 ASM 磁盤

wget http://10.64.39.210/asmlib/asmlib.repo -P /etc/yum.repos.d/
yum clean all
yum install -y oracleasm-support oracleasmlib oracleasm


7、對共享磁盤進行分區
parted /dev/sdc
mklabel gpt
mkpart primary 20G  520G 
mkpart primary 520G  1020G 
mkpart primary 1020G  1520G 
mkpart primary 1520G  2020G 
mkpart primary 2020G  2520G 
mkpart primary 2520G  3020G 
mkpart primary 3020G  3520G 
mkpart primary 3520G  4020G 
mkpart primary 4020G  4520G 
mkpart primary 4520G  5020G 
mkpart primary 5020G  5520G 
mkpart primary 5520G  6020G 
mkpart primary 6020G  6520G 
mkpart primary 6520G  7020G 
mkpart primary 7020G  7520G 
mkpart primary 7520G  8020G 
mkpart primary 8020G  8520G 
mkpart primary 8520G  9020G 
mkpart primary 9020G  9520G 
mkpart primary 9520G  10020G 
mkpart primary 10020G  10520G 
mkpart primary 10520G  11020G 
mkpart primary 11020G  11950G 
p
quit

8、root 用戶配置 ASMLib
先重啟一下
/etc/init.d/oracleasm configure
grid
asmdba
y
y

9、設置共享磁盤
節點1

/usr/sbin/oracleasm createdisk OCR_VOTE /dev/sdb1
/usr/sbin/oracleasm createdisk ASMDATA /dev/sdb2
/usr/sbin/oracleasm createdisk BACKUP /dev/sdb3

節點2（rac2）上以root用戶登錄，使用scandisks命令掃描已經創建的ASM磁盤
也就是說，我們只需要在節點 1 上創建 ASM 磁盤，其他節點不需要。


/etc/init.d/oracleasm scandisks

Scanning the system for Oracle ASMLib disks:               [  OK  ]

/etc/init.d/oracleasm listdisks

ASMDATA
BACKUP
OCR_VOTE

ASM磁盤組配置完成。

systemctl status oracleasm
systemctl restart oracleasm
systemctl daemon-reload

cd /usr/lib/modules


10、下載gird和oracle包
mkdir -p /home/grid/soft
mkdir -p /home/oracle/soft

wget -P /home/grid/soft http://10.64.39.210/download/p13390677_112040_Linux-x86-64_3of7.zip

wget -P /home/oracle/soft http://10.64.39.210/download/p13390677_112040_Linux-x86-64_1of7.zip

wget -P /home/oracle/soft http://10.64.39.210/download/p13390677_112040_Linux-x86-64_2of7.zip


chown -R grid:oinstall /home/grid/soft
chown -R oracle:oinstall /home/oracle/soft

11、安裝cvu包

rac1和rac2節點上以 root 用戶身份安裝操作系統程序包cvuqdisk-1.0.9-1.rpm，此包位於grid安裝包下rpm目錄下。

rpm -ivh http://10.64.39.210/download/cvuqdisk-1.0.9-1.rpm
yum install -y http://10.64.39.210/download/compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
rpm -ivh --force --nodeps http://10.64.39.210/download/pdksh-5.2.14-30.x86_64.rpm

12、rac1和rac2使用CUV驗證硬件和操作系統配置

進入解壓完畢的grid安裝包目錄下，執行

su - grid

cd grid

/home/grid/soft/grid/runcluvfy.sh stage -post hwos -n lsrkzyk1,lsrkzyk2 -verbose


lsrkzyk1和lsrkzyk2執行集群預檢查


/home/grid/soft/grid/runcluvfy.sh stage -pre crsinst -n lsrkzyk1,lsrkzyk2 -verbose

全部為pass即通過，個別的如 dns  沒通過（failed）可以忽略。

1、安裝acfs
find / -name acfsroot 
/u01/grid/bin/acfsroot install
2、啟動acfs
find / -name acfsload
/u01/grid/bin/acfsload start -s

grid 啟動數據庫
srvctl start database -d lsrkzyk  
srvctl stop database -d dzrkzyk  
srvctl start database -d dzrkzyk
crsctl status resource ora.lsrkzyk.db -f

srvctl start instance -d lsrkzyk -i lsrkzyk1

1、檢查兩節點oracle、grid用戶組 是否有asmdba dba oinstall
2、賦予oracle.grid 權限 
chmod 6755  $ORACLE_HOME/bin/oracle
--chmod 6755 /u01/grid/bin/oracle

--orqcle用戶過期處理 （方法一）
--查看數據庫密碼過期時間

sqlplus / as sysdba

select * from dba_profiles where profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';
alter profile default limit password_life_time unlimited;
修改前已經過期了的需要再次修改密碼。
alter user  user_name identified by user_passwd;

__________________________________
--解決密碼過期（sys用戶） （方法二）
1、創建一個profile（相當於創建一個角色）
create profile  passwd_unlimit limit  PASSWORD_LIFE_TIME unlimited;
ALTER profile  passwd_unlimit limit COMPOSITE_LIMIT          UNLIMITED; 
ALTER profile  passwd_unlimit limit SESSIONS_PER_USER        UNLIMITED; 
ALTER profile  passwd_unlimit limit CPU_PER_SESSION          UNLIMITED; 
ALTER profile  passwd_unlimit  limit CPU_PER_CALL             UNLIMITED; 
ALTER profile  passwd_unlimit  limit LOGICAL_READS_PER_SESSION UNLIMITED; 
ALTER profile  passwd_unlimit  limit LOGICAL_READS_PER_CALL   UNLIMITED; 
ALTER profile  passwd_unlimit limit IDLE_TIME                UNLIMITED; 
ALTER profile  passwd_unlimit limit CONNECT_TIME             UNLIMITED; 
ALTER profile  passwd_unlimit  limit PRIVATE_SGA              UNLIMITED; 
ALTER profile  passwd_unlimit limit FAILED_LOGIN_ATTEMPTS    10      ; 
ALTER profile  passwd_unlimit limit PASSWORD_REUSE_TIME      UNLIMITED; 
ALTER profile  passwd_unlimit limit PASSWORD_REUSE_MAX       UNLIMITED; 
ALTER profile  passwd_unlimit  limit PASSWORD_VERIFY_FUNCTION NULL    ; 
ALTER profile  passwd_unlimit  limit PASSWORD_LOCK_TIME       1       ; 
ALTER profile  passwd_unlimit  limit PASSWORD_GRACE_TIME      7       ; 

2、用戶改成這個角色
alter user  SCRK5109_QRY  profile   passwd_unlimit; 
3、查看用戶角色
SELECT  *  FROM  dba_profiles；
select  *  from  dba_users;
select  username, user_id, account_status, expiry_date, profile  from  dba_users;

---后期修改數據庫時區-（先改系統時區）
select dbtimezone,systimestamp from dual;
+08:00
29-JUL-19 09.40.03.769147 AM +08:00

select sysdate from dual;

alter database set time_zone='+8:00';
--grid 用戶
srvctl stop database -d msrkzyk  
srvctl start database -d msrkzyk


--aix ntp
startsrc -s xntpd
stopsrc -s xntpd

lssrc -ls xntpd
xntpdc -c peers

---------------------------------------------------------------------
acfs 更換掛載點
root 下
1、取消兩個節點的掛載
umount /掛載目錄
2、取消acfs文件的注冊
acfsutil registry -d /u01
3、刪除acfs系統
acfsutil rmfs /dev/asm/asm_pic
4、查看asm volume 信息
su - grid
asmcmd
 volinfo -G ACF -a
5、禁用asm volume

voldisable -G ACFS ACFS  -- 前一個是disgroup name 后一個acfs是volume name
volinfo  -G ACFS -a
6、刪除asm volume
voldelete -G ACFS ACFS
volinfo  -G ACFS -a

SQL> alter system set job_queue_processes=1000;

System altered.
