在ORACLE linux as 4上安装 ORACLE 10G RAC

原创 Linux操作系统 作者:sduzjw 时间:2011-08-06 19:11:05 0 删除 编辑
这两天在看ORACLE的网络部分的文档,看了最后,唉,好多都是RAC的配置,手上又没现成的环境, 以前的环境又全都扔了,只好安装一个。
根据ORACLE的安装文档一步一步做下来,没什么惊险的。

但共享存储使用的starwind模拟出来的,在LINUX检测时会出现磁盘挂载顺序不对的问题,我还没想出好的办法解决,临时使用以下的方法:

设置CRS在LINUX启动时禁止自动启动
/etc/init.d/init.crs disable



设置RAW的权限,编辑/etc/udev/permissions.d/50*  此文件不支持通配符
# raw devices
ram*:root:disk:0660
#raw/*:root:disk:0660
raw/raw1:root:oinstall:0640
raw/raw2:oracle:oinstall:0640

raw/raw3:oracle:dba:0660
raw/raw4:oracle:dba:0660
raw/raw5:oracle:dba:0660
raw/raw6:oracle:dba:0660
raw/raw7:oracle:dba:0660
raw/raw8:oracle:dba:0660
raw/raw9:oracle:dba:0660
raw/raw10:oracle:dba:0660
raw/raw11:oracle:dba:0660
raw/raw12:oracle:dba:0660
raw/raw13:oracle:dba:0660
raw/raw14:oracle:dba:0660
raw/raw15:oracle:dba:0660
raw/raw16:oracle:dba:0660
raw/raw17:oracle:dba:0660 

这样设置以后可以把ISCSI,RAWDEVICES服务停止,在系统启动完成后,启动ISCSI,检查挂载的磁盘顺序是否正确,
fdisk -l
如果不正确,重新启动ISCSI
service iscsi start/restart/stop
直到挂载顺序正确后启动RAW服务会自动设置相关的RAW设备的权限
service rawdevices start/restart/stop

RAW的绑定情况

[root@rac2 ~]# raw -qa
/dev/raw/raw1:  bound to major 8, minor 17
/dev/raw/raw2:  bound to major 8, minor 18
/dev/raw/raw3:  bound to major 8, minor 33
/dev/raw/raw4:  bound to major 8, minor 34
/dev/raw/raw5:  bound to major 8, minor 35
/dev/raw/raw6:  bound to major 8, minor 37
/dev/raw/raw7:  bound to major 8, minor 38
/dev/raw/raw8:  bound to major 8, minor 39
/dev/raw/raw9:  bound to major 8, minor 40
/dev/raw/raw10: bound to major 8, minor 41
/dev/raw/raw11: bound to major 8, minor 42
/dev/raw/raw12: bound to major 8, minor 43
/dev/raw/raw13: bound to major 8, minor 44
/dev/raw/raw14: bound to major 8, minor 45
/dev/raw/raw15: bound to major 8, minor 46
/dev/raw/raw16: bound to major 8, minor 47
/dev/raw/raw17: bound to major 8, minor 19
[root@rac2 ~]# 


手工启动CRS
/etc/init.d/init.crs start
[root@rac2 ~]# /etc/init.d/init.crs start
Startup will be queued to init within 90 seconds.
[root@rac2 ~]# 


安装 过程中出现
Enter value for datafile:
ERROR:
ORA-12547: TNS:lost contact
一时被这个问题给折腾晕了,看监听发现两个监听还是不太正常,原来的监听:
RAC1上的监听
LISTENER_RAC1 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)(IP = FIRST))
    )
  )
在RAC2上面的127.0.0.1处则使用与rac1-vip同网段的那个IP,我把RAC2上监听改成与RAC1上的一样。

改了后发现还是没解决,又在网上找了半天发现是libaio没安装引起的,实际上在安装日志中已经显示了错误的原因:

oracledevdb1: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
oracledevdb1: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
oracledevdb1: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
oracledevdb1: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
oracledevdb1: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
oracledevdb1: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

为什么出这个错误的,全是手误,太不细心了,在安装libaio时是单独把RPM文件拿 出来安装的,结果文件搞错了,弄成这个了
libao-0.8.5-2.EL.0.i386.rpm
实际上应该是这个
libaio-0.3.105-2.i386.rpm

两个包的开头只差了一个字段i,结果就给搞成如此。以前怎么着也安装过5,6回了,也没出什么问题,还是不细心惹的。
把正确的RMP安装全,安装过程就正常了
