• CentOS 7.2安装11g Grid Infrastructure


     
    Preface
     
        Oracle claimed that 11g RAC is supported on Redhat Linux 7 and above version,but there're still some incompatible issues in inplementing 11g GI on it.There're some main steps showed below.
     
    Precedure
     
    ###Step 1.PREPARE PHASE###
     
    1. Modify /etc/hosts(all nodes).
     1 vim /etc/hosts
     2 cat /etc/hosts
     3 #public ip
     4 192.168.56.11 rac1    rac1-pub
     5 192.168.56.12 rac2    rac2-pub
     6 #private ip    
     7 10.10.10.11    rac1-priv
     8 10.10.10.12    rac2-priv
     9 #virtual ip
    10 192.168.56.13 rac1-vip
    11 192.168.56.14 rac2-vip
    12 #scan ip
    13 192.168.56.15 rac-scan

    2. Disable firewall & selinux(all nodes).

    1 systemctl stop firewalld
    2 systemctl status firewalld
    3 systemctl status firewalld
    4 vim /etc/selinux/config
    5 cat /etc/selinux/config
    6 SELINUX=disabled
    7 sestatus -v
    8 SELinux status:                 disabled

    3. Install packages(all nodes).

    1 yum -y install binutils compat-db compat-libcap1 compat-libstdc++-33 control-center elfutils-libelf-devel gcc gcc-c++ glibc glibc-common gnome-libs libaio-devel libstdc++ libstdc++-devel make pdksh sysstat xscreensaver libaio openmotif21 smartmontools

    4. Configure ssh connectivities(all nodes,both grid & oracle).

     1 rac1:
     2 ssh-keygen -t rsa
     3 rac2:
     4 ssh-keygen -t rsa
     5 rac1:
     6 cat  ~/.ssh/id_rsa.pub  >> ~/.ssh/authorized_keys
     7 ssh rac2 cat ~/.ssh/id_rsa.pub  >> ~/.ssh/authorized_keys
     8 rac2:
     9 cat  ~/.ssh/id_rsa.pub  >> ~/.ssh/authorized_keys
    10 ssh rac1 cat ~/.ssh/id_rsa.pub  >> ~/.ssh/authorized_keys
    11 
    12 //Test execute command on remote host without password.
    13 ssh rac1 date
    14 ssh rac2 date

    5. Add user & usergroups(all nodes).

    1 groupadd oinstall
    2 groupadd dba
    3 groupadd oper
    4 groupadd asmdba    
    5 groupadd asmoper
    6 groupadd asmadmin 
    7 useradd -g oinstall -G dba,oper,asmdba oracle
    8 useradd -g oinstall -G asmdba,dba,asmadmin,asmoper grid

    6. Create directory & grant privileges(all nodes).

    1 mkdir /u01
    2 mkdir /u01/gridbase
    3 mkdir /u01/gridhome
    4 mkdir /u01/oracle
    5 chown -R grid:oinstall /u01
    6 chown -R oracle:oinstall /u01/oracle
    7 chmod -R g+w /u01

    7. Modify environment variables((all nodes,both grid & oracle).

     1 grid(rac1):
     2 vim /home/grid/.bash_profile
     3 cat /home/grid/.bash_profile
     4 ORACLE_BASE = /u01/gridbase
     5 ORACLE_HOME = /u01/gridhome
     6 ORACLE_SID = +ASM1
     7 PATH = $ORACLE_HOME/bin:$PATH
     8 LD_LIBRARY_PATH = $ORACLE_HOME/lib:$LD_LIBRARY_PATH
     9 export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH
    10 
    11 grid(rac2):
    12 vim /home/grid/.bash_profile
    13 cat /home/grid/.bash_profile
    14 ORACLE_BASE = /u01/gridbase
    15 ORACLE_HOME = /u01/gridhome
    16 ORACLE_SID = +ASM2
    17 PATH=$ORACLE_HOME/bin:$PATH
    18 LD_LIBRARY_PATH = $ORACLE_HOME/lib:$LD_LIBRARY_PATH
    19 export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH
    20 
    21 oracle(rac1):
    22 vim /home/oracle/.bash_profile
    23 cat /home/oracle/.bash_profile
    24 ORACLE_BASE = /u01/oracle
    25 ORACLE_HOME = /u01/oracle/db
    26 ORACLE_SID = ora11g1
    27 PATH = $ORACLE_HOME/bin:$PATH
    28 LD_LIBRARY_PATH = $ORACLE_HOME/lib:$LD_LIBRARY_PATH
    29 export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH
    30 
    31 oracle(rac2):
    32 vim /home/oracle/.bash_profile
    33 cat /home/oracle/.bash_profile
    34 ORACLE_BASE = /u01/oracle
    35 ORACLE_HOME = /u01/oracle/db
    36 ORACLE_SID = ora11g2
    37 PATH = $ORACLE_HOME/bin:$PATH
    38 LD_LIBRARY_PATH = $ORACLE_HOME/lib:$LD_LIBRARY_PATH
    39 export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH
    40 
    41 //Make it take effect(rac1 & rac2).
    42 source /home/oracle/.bash_profile
    43 source /home/grid/.bash_profile

    8. Modify kernel parameters(all nodes).

     1 vim /etc/sysctl.conf
     2 cat vim /etc/sysctl.conf
     3 kernel.msgmnb = 65536 
     4 kernel.msgmax = 65536 
     5 kernel.shmmax = 1073741824 //1G memory for Oracle.
     6 kernel.shmall = 2097152 
     7 kernel.shmmni = 4096 
     8 fs.aio-max-nr = 1048576 
     9 fs.file-max = 6815744 
    10 kernel.sem = 250 32000 100 128 
    11 net.ipv4.ip_local_port_range = 9000 65500 
    12 net.core.rmem_default = 262144 
    13 net.core.rmem_max = 4194304 
    14 net.core.wmem_default = 262144 
    15 net.core.wmem_max = 1048576
    16 
    17 //Make the kernel parameters take effect.
    18 sysctl -p

    9. Modify limites(all nodes).

     1 vim /etc/security/limits.conf
     2 cat /etc/security/limits.conf
     3 #oracle
     4 oracle soft nproc 2047 
     5 oracle hard nproc 16384 
     6 oracle soft nofile 1024 
     7 oracle hard nofile 65536 
     8 oracle soft stack 10240 
     9 #grid
    10 grid soft nproc 2047 
    11 grid hard nproc 16384 
    12 grid soft nofile 1024 
    13 grid hard nofile 65536 
    14 grid soft stack 10240

    10. Modify pam limits(all nodes).

    1 vim /etc/pam.d/login
    2 cat /etc/pam.d/login
    3 session required /lib64/security/pam_limits.so 
    4 session required pam_limits.so

    11. Modify profile(all nodes).

    1 vim /etc/profile
    2 cat /etc/profile
    3 if [ $USER = "oracle" ]||[$USER = "grid" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else
    4 43/ 136
    5 ulimit -u 16384 -n 65536
    6 fi
    7 fi
    ###Step 2.CREATE SHARED DISKS WITH ASMLIB###
     
    1. Create three new disks and make partitions on them with "fdisk"(rac1 only).
     1 fdisk -l
     2 fdisk /dev/sdc
     3 n
     4 enter
     5 enter
     6 enter
     7 w
     8 
     9 fdisk /dev/sdd
    10 n
    11 enter
    12 enter
    13 enter
    14 w
    15 
    16 fdisk /dev/sde
    17 n
    18 enter
    19 enter
    20 enter
    21 w
    22 
    23 ll /dev/sd*
    24 ...
    25 /dev/sdc1
    26 /dev/sdd1
    27 /dev/sde1

    2. Install asmlib packages(both rac1 & rac2).

    1 yum -y localinstall kmod-oracleasm oracleasm-support oracleasmlib

    3. Bind the shared disks with "oracleasm"(root execute).

     1 rac1:
     2 oracleasm configure -i
     3 grid
     4 asmadmin
     5 y
     6 y
     7 
     8 oracleasm init
     9 
    10 oracleasm createdisk ASMDISK1 sdc1
    11 oracleasm createdisk ASMDISK2 sdd1
    12 oracleasm createdisk ASMDISK3 sde1
    13 
    14 oracleasm listdisks
    15 ASMDISK1
    16 ASMDISK2
    17 ASMDISK3
    18 
    19 oracleasm scandisks
    20 
    21 rac2:
    22 oracleasm  configure -i
    23 grid
    24 asmadmin
    25 y
    26 y
    27 
    28 oracleasm init
    29 
    30 //Reboot rac2 and check the shared disks.
    31 oracleasm listdisks
    32 ASMDISK1
    33 ASMDISK2
    34 ASMDISK3
    ###Step 3.SOFTWARE INSTALLATION(rac1 only)###
     
    1. Unzip the grid software package.
    1 cd /u01
    2 unzip p13390677_112040_Linux-x86-64_3of7.zip
    3 chown -R grid:oinstall  /u01/grid
    2. Check the prerequisite of installation.
    1 cd /u01/grid
    2 ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose
    3. Install X windows System of linux.
    1 yum -y groupinstall "X Windows System"
    4. Set xhost and DISPLAY variable.
    1 xhost +
    2 export DISPLAY=192.168.56.99:0.0
    5. Install grid software with Oracle GUI.
    1 ./runInstaller -ignorePrereq
    2 
    3 //I've tried many times not add "-ignorePrereq" option,but the OUI will stuck at 61% when checking the semaphore.I'm afraid it's the incompatible poit installing 11g rac on CentOS 7.2.The picture of stuck point shows below.

     

    6. Execute below scripts in RAC1,RAC2 in order(This step really took me quit a long time to solve it,So I'd like to put the details below).

      1 /u01/oraInventory/orainstRoot.sh
      2 /u01/gridhome/root.sh
      3 
      4 I got an error bellow when execute "/u01/gridhome/root.sh" script:
      5 
      6 Adding Clusterware entries to inittab
      7 ohasd failed to start
      8 Failed to start the Clusterware. Last 20 lines of the alert log follow:
