rhel7安装oracle11gr2rac遇到的问题

rhel7 安装11g r2 rac的方法跟之前的还是有很大的区别&＃xff0c;以至于遇到很多坑&＃xff0c;这里汇总下&＃xff1a;

1、共享磁盘udev 绑定方式

这个跟rhel7 之前的版本不一样&＃xff0c;特别是磁盘uuid命令方式变化了很多&＃xff0c;udev启动方式也发生了变化&＃xff0c;

for disk in &＃96;ls /dev/sd*&＃96;doecho $disk /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device&＃61;$diskdone

映射文件&＃xff1a;

cat /etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL&＃61;&＃61;"sd?1", SUBSYSTEM&＃61;&＃61;"block", PROGRAM&＃61;&＃61;"/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT&＃61;&＃61;"36000c298981418c7e8a25a89d0f836c9", SYMLINK&＃43;&＃61;"asm-diskb", OWNER&＃61;"grid", GROUP&＃61;"asmadmin", MODE&＃61;"0660"
KERNEL&＃61;&＃61;"sd?1", SUBSYSTEM&＃61;&＃61;"block", PROGRAM&＃61;&＃61;"/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT&＃61;&＃61;"36000c29dce09d16de88f435217838c9e", SYMLINK&＃43;&＃61;"asm-diskc", OWNER&＃61;"grid", GROUP&＃61;"asmadmin", MODE&＃61;"0660"
KERNEL&＃61;&＃61;"sd?1", SUBSYSTEM&＃61;&＃61;"block", PROGRAM&＃61;&＃61;"/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT&＃61;&＃61;"36000c29c3438303241fd1291834b1bd0", SYMLINK&＃43;&＃61;"asm-diskd", OWNER&＃61;"grid", GROUP&＃61;"asmadmin", MODE&＃61;"0660"
KERNEL&＃61;&＃61;"sd?1", SUBSYSTEM&＃61;&＃61;"block", PROGRAM&＃61;&＃61;"/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT&＃61;&＃61;"36000c291dec502efa9d3ae53c99f0028", SYMLINK&＃43;&＃61;"asm-diske", OWNER&＃61;"grid", GROUP&＃61;"asmadmin", MODE&＃61;"0660"
KERNEL&＃61;&＃61;"sd?1", SUBSYSTEM&＃61;&＃61;"block", PROGRAM&＃61;&＃61;"/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT&＃61;&＃61;"36000c29e29a4bcd75acea14e982ea49d", SYMLINK&＃43;&＃61;"asm-diskf", OWNER&＃61;"grid", GROUP&＃61;"asmadmin", MODE&＃61;"0660"

启动udev:

/sbin/udevadm trigger --type&＃61;devices --action&＃61;change

udevadm control --reload-rules

2、依赖包缺失

依赖包‘compat-libstdc&＃43;&＃43;’在rhel 7 的ISO 镜像文件中不存在&＃xff0c;所以需要自己去下载安装

3、运行 root.sh 脚本错处&＃xff0c;启动ohas服务失败:

"Adding Clusterware entries to inittab

ohasd failed to start

Failed to start the Clusterware. Last 20 lines of the alert log follow: 

2015-05-23 23:37:45.460: 

[client(13782)]CRS-2101:The OLR was formatted using version 3."

根本原因是rhel 7 系统服务管理方式发生了变化&＃xff0c;由原来的init 变成了  systemctl 来管理&＃xff0c;所以这里rac 的集群服务需要使用cyctemctl 来管理&＃xff0c;但是11g r2 还是默认使用init来管理&＃xff0c;导致系统启动不了ohasd 服务.

解决方法&＃xff1a;

在RHEL 7中ohasd需要被设置为一个服务&＃xff0c;在运行脚本root.sh之前。

步骤如下&＃xff1a;

 

1. 以root用户创建服务文件

#touch /usr/lib/systemd/system/ohas.service

#chmod 777 /usr/lib/systemd/system/ohas.service

 

2. 将以下内容添加到新创建的ohas.service文件中

[root&＃64;rac1 init.d]# cat /usr/lib/systemd/system/ohas.service

[Unit]

Description&＃61;Oracle High Availability Services

After&＃61;syslog.target

[Service]

ExecStart&＃61;/etc/init.d/init.ohasd run >/dev/null 2>&1 Type&＃61;simple

Restart&＃61;always

[Install]

WantedBy&＃61;multi-user.target

 

3. 以root用户运行下面的命令

systemctl daemon-reload

systemctl enable ohas.service

systemctl start ohas.service

 

4. 查看运行状态

[root&＃64;rac1 init.d]# systemctl status ohas.service

ohas.service - Oracle High Availability Services

   Loaded: loaded (/usr/lib/systemd/system/ohas.service; enabled)

   Active: failed (Result: start-limit) since Fri 2015-09-11 16:07:32 CST; 1s ago

  Process: 5734 ExecStart&＃61;/etc/init.d/init.ohasd run >/dev/null 2>&1 Type&＃61;simple (code&＃61;exited, status&＃61;203/EXEC)

 Main PID: 5734 (code&＃61;exited, status&＃61;203/EXEC)

Sep 11 16:07:32 rac1 systemd[1]: Failed to start Oracle High Availability Services.

Sep 11 16:07:32 rac1 systemd[1]: Unit ohas.service entered failed state.

 

此时状态为失败&＃xff0c;原因是现在还没有/etc/init.d/init.ohasd文件。

 

下面可以运行脚本root.sh 不会再报ohasd failed to start错误了。

 

 

 

如果还是报ohasd failed to start错误&＃xff0c;可能是root.sh脚本创建了init.ohasd之后&＃xff0c;ohas.service没有马上启动&＃xff0c;解决方法参考以下&＃xff1a;

 

当运行root.sh时&＃xff0c;一直刷新/etc/init.d &＃xff0c;直到出现 init.ohasd 文件&＃xff0c;马上手动启动ohas.service服务 命令&＃xff1a;systemctl start ohas.service 

 

[root&＃64;rac1 init.d]# systemctl status ohas.service
