Oracle 12c 基于ASM 的单实例 搭建手册
从Oracle 10g开始,Oracle 开始推广ASM的使用,到了11g,RAC 集群已经必须使用ASM,所以对ASM的掌握程度也决定RAC的运维水平,这篇Blog 演示 Oracle12c 基于ASM 的单实例的的环境搭建。
这样即可以玩12c 的ASM,又不需要起2个集群,从而方便学习。具体环境搭建步骤如下。
1 安装需要的RPM 包

libXau-1.0.5 (i686)
libxcb-1.5 (i686)
libXi-1.3 (i686)
2 创建ASM disk 并用UDEV 绑定
创建6个3G 的disk,这个直接使用VirtualBox命令来创建。 创建之前需要先关闭虚拟机。
用如下脚本获取绑定脚本:
do
echo"KERNEL==\"sd*\", BUS==\"scsi\",PROGRAM==\"/sbin/scsi_id -g -u /dev/\$name\", RESULT==\"`/sbin/scsi_id -g -u/dev/sd$i`\", NAME=\"12casm-disk$i\", OWNER=\"grid\",GROUP=\"asmadmin\", MODE=\"0660\""
done
KERNEL=="sd*",BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",RESULT=="1ATA_VBOX_HARDDISK_VB626d9087-8bf68e7e",NAME="12casm-diskb", OWNER="grid",GROUP="asmadmin", MODE="0660"
KERNEL=="sd*",BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",RESULT=="1ATA_VBOX_HARDDISK_VBf5a8c435-19b9adf9",NAME="12casm-diskc", OWNER="grid",GROUP="asmadmin", MODE="0660"
KERNEL=="sd*",BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",RESULT=="1ATA_VBOX_HARDDISK_VB13895f62-318c2cb4",NAME="12casm-diskd", OWNER="grid",GROUP="asmadmin", MODE="0660"
KERNEL=="sd*",BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",RESULT=="1ATA_VBOX_HARDDISK_VB5049991a-741b6a85",NAME="12casm-diske", OWNER="grid",GROUP="asmadmin", MODE="0660"
KERNEL=="sd*",BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",RESULT=="1ATA_VBOX_HARDDISK_VB6ad43135-cac8a708",NAME="12casm-diskf", OWNER="grid",GROUP="asmadmin", MODE="0660"
KERNEL=="sd*",BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",RESULT=="1ATA_VBOX_HARDDISK_VBe6fb6130-2a921dde",NAME="12casm-diskg", OWNER="grid",GROUP="asmadmin", MODE="0660"
将产生的结果添加到/etc/udev/rules.d/99-oracle-asmdevices.rules文件。
[root@12cAsm dave]# start_udev
Starting udev: [ OK ]
[root@12cAsm dave]#
--查看设备:
[root@12cAsm dave]# ll /dev/12casm*
brw-rw----. 1 grid asmadmin 8, 16 Nov 2900:35 /dev/12casm-diskb
brw-rw----. 1 grid asmadmin 8, 32 Nov 2900:35 /dev/12casm-diskc
brw-rw----. 1 grid asmadmin 8, 48 Nov 2900:35 /dev/12casm-diskd
brw-rw----. 1 grid asmadmin 8, 64 Nov 2900:35 /dev/12casm-diske
brw-rw----. 1 grid asmadmin 8, 80 Nov 2900:35 /dev/12casm-diskf
brw-rw----. 1 grid asmadmin 8, 96 Nov 2900:35 /dev/12casm-diskg
[root@12cAsm dave]#
至此配置结束,在ASM的配置中,ASM_DISKSTRING参数指向‘/dev/asm-disk*‘就可以了。
3 禁用防火墙和SELNUX
关闭防火墙:
service iptables status
service iptables stop
chkconfig iptables off
chkconfig iptables --list
设置/etc/selinux/config 文件,将SELINUX设置为disabled。
4 创建目录结构
mkdir -p /u01/grid
mkdir -p /u01/app/grid/12.1.0
chown -R grid:oinstall /u01
mkdir -p /u01/app/oracle/12.1.0/db_1
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01
5 添加组和用户并设置环境变量
groupadd -g 1000 oinstall
groupadd -g 1200 asmadmin
groupadd -g 1201 asmdba
groupadd -g 1202 asmoper
groupadd -g 1300 dba
groupadd -g 1301 oper
useradd -m -u 1100 -g oinstall -Gasmadmin,asmdba,asmoper,dba -d /home/grid -s /bin/bash grid
useradd -m -u 1101 -g oinstall -Gdba,oper,asmdba -d /home/oracle -s /bin/bash oracle
确认用户信息:
[root@rac1 ~]# id oracle
uid=502(oracle) gid=507(oinstall)groups=507(oinstall),502(dba),503(oper),506(asmdba)
[root@rac1 ~]# id grid
uid=1100(grid) gid=507(oinstall)groups=507(oinstall),504(asmadmin),506(asmdba),505(asmoper)
修改密码:
passwd oracle
passwd grid
修改grid用户的.bash_profile.注意每个节点的不同内容:
export ORACLE_SID=+ASM
export ORACLE_BASE=/u01/grid
export ORACLE_HOME=/u01/app/grid/12.1.0
exportPATH=$ORACLE_HOME/bin:$PATH:/usr/local/bin/:.
export TEMP=/tmp
export TMP=/tmp
export TMPDIR=/tmp
umask 022
修改oracle 用户的.bash_profile,注意每个节点的不同内容:
ORACLE_SID=dave;export ORACLE_SID
ORACLE_UNQNAME=dave;export ORACLE_UNQNAME
JAVA_HOME=/usr/local/java; export JAVA_HOME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/12.1.0/db_1; exportORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
NLS_DATE_FORMAT="YYYY:MM:DD HH24:MI:SS";export NLS_DATE_FORMAT
NLS_LANG=american_america.ZHS16GBK; exportNLS_LANG
TNS_ADMIN=$ORACLE_HOME/network/admin; exportTNS_ADMIN
ORA_NLS11=$ORACLE_HOME/nls/data; export ORA_NLS11
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORA_CRS_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export CLASSPATH
THREADS_FLAG=native; export THREADS_FLAG
export TEMP=/tmp
export TMPDIR=/tmp
umask 022
6 为安装用户设置资源限制
6.1 修改/etc/security/limits.conf
以 root 用户身份,在节点上,在 /etc/security/limits.conf 文件中添加如下内容,或者执行执行如下命令:
[root@12cAsm dave]# cat >>/etc/security/limits.conf <<EOF
> grid soft nproc 2047
> grid hard nproc 16384
> grid soft nofile 1024
> grid hard nofile 65536
> oracle soft nproc 2047
> oracle hard nproc 16384
> oracle soft nofile 1024
> oracle hard nofile 65536
> EOF
[root@12cAsm dave]#
6.2 修改/etc/pam.d/login
[root@12cAsmdave]# cat >> /etc/pam.d/login <<EOF
>session required pam_limits.so
> EOF
[root@12cAsmdave]#
6.3 shell 的限制
对默认的 shell 启动文件进行以下更改,以便更改所有 Oracle 安装所有者的 ulimit 设置:
[root@12cAsm dave]# cat >>/etc/profile <<EOF
> if [ /$USER = "oracle" ] ||[ /$USER = "grid" ]; then
> if [ /$SHELL = "/bin/ksh" ]; then
> ulimit -p 16384
> ulimit -n 65536
> else
> ulimit -u 16384 -n 65536
> fi
> umask 022
> fi
> EOF
[root@12cAsm dave]#
7 修改内核参数/etc/sysctl.conf
在sysctl.conf 中加入以下内容:
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
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.panic_on_oops = 30
8 安装Clusterware
安装之前要确认/etc/hosts 配置:
[root@12cAsm dave]# cat /etc/hosts
127.0.0.1 localhost 12cAsm
不然会报错。
已grid 用户运行安装程序: runInstaller
…
其他都是下一步的操作。 这里不截图了。
执行最后会让我们运行一个root.sh 脚本。
[root@12cAsm /]#/u01/oraInventory/orainstRoot.sh
Changing permissions of /u01/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions forworld.
Changing groupname of /u01/oraInventory tooinstall.
The execution of the script is complete.
[root@12cAsm /]#
[root@12cAsm /]#/u01/app/grid/12.0.1/root.sh
Performing root user operation.
The following environment variables are setas:
ORACLE_OWNER= grid
ORACLE_HOME= /u01/app/grid/12.0.1
Enter the full pathname of the local bindirectory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...
Creating /etc/oratab file...
Entries will be added to the /etc/oratabfile as needed by
Database Configuration Assistant when adatabase is created
Finished running generic part of rootscript.
Now product-specific root actions will beperformed.
To configure GridInfrastructure for a Stand-Alone Server run the following command as the rootuser:
/u01/app/grid/12.0.1/perl/bin/perl-I/u01/app/grid/12.0.1/perl/lib -I/u01/app/grid/12.0.1/crs/install/u01/app/grid/12.0.1/crs/install/roothas.pl
To configure GridInfrastructure for a Cluster execute the following command as grid user:
/u01/app/grid/12.0.1/crs/config/config.sh
This command launches the GridInfrastructure Configuration Wizard. The wizard also supports silent operation,and the parameters can be passed through the response file that is available inthe installation media.
[root@12cAsm /]#
我们这里是单节点的ASM,所以执行如下SQL:
/u01/app/grid/12.0.1/perl/bin/perl-I/u01/app/grid/12.0.1/perl/lib -I/u01/app/grid/12.0.1/crs/install/u01/app/grid/12.0.1/crs/install/roothas.pl
