HP-UX 11g RAC安装 记录

环境：HP-UX 11.31 + GI 11.2.0.4 + Oracle 11.2.0.4

背景：本文只对HP-UX平台安装11g RAC环境过程中，针对一些跟Linux平台有差异的地方进行简单记录备忘。

关于安装部署11g RAC的完整过程可参考：http://www.cnblogs.com/jyzhao/p/4679203.html

1. 查看网络
2. 新建用户
3. 异步I/O
4. 手动配置互信
5. 预安装检查
6. xterm图形化
7. ASM磁盘组权限
8. scan IP修改

1. 查看网络

```
netstat -in
```

2. 新建用户

新建用户的默认用户目录是需要手工赋权和指定的，比如：
```
mkdir -p /home/grid
mkdir -p /home/oracle
chown grid:oinstall /home/grid
chown oracle:oinstall /home/oracle

useradd -g oinstall -G asmadmin,asmdba,asmoper -u 700 -d /home/grid grid

useradd -g oinstall -G dba,asmdba,oper -u 800 -d /home/oracle oracle

<h1 id="3">3. 异步I/O</h1>
开启异步I/O，查看/dev/async的信息：

root@rnopdb01:/dev/rdisk #ll /dev/async

crw-rw-rw- 1 bin bin 101 0x000000 Mar 15 12:53 /dev/async

root@rnopdb01:/dev/rdisk #

root@rnopdb01:/dev/rdisk #

root@rnopdb01:/dev/rdisk #

root@rnopdb01:/dev/rdisk #

root@rnopdb01:/dev/rdisk #rm /dev/async

root@rnopdb01:/dev/rdisk # /sbin/mknod /dev/async c 101 0x4

root@rnopdb01:/dev/rdisk #chmod 666 /dev/async

root@rnopdb01:/dev/rdisk #ll /dev/async

crw-rw-rw- 1 root sys 101 0x000004 Mar 19 11:11 /dev/async

<h1 id="4">4. 手动配置互信</h1>
grid用户配置互信：

1).在主节点rnopdb01上grid用户下，ssh-keygen生成密钥

su – grid

$ mkdir ~/.ssh

$ ssh-keygen -t rsa

$ ssh-keygen -t dsa

2).在节点rnopdb02上执行相同的操作，确保通信无阻

su – grid

$ mkdir ~/.ssh

$ ssh-keygen -t rsa

$ ssh-keygen -t dsa

3).在主节点rnopdb01上grid用户执行以下操作

$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

$ ssh rnopdb02 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ ssh rnopdb02 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

$ scp ~/.ssh/authorized_keys rnopdb02:~/.ssh/authorized_keys

ssh rnopdb01

ssh rnopdb02

oracle用户配置互信方法同上。

<h1 id="5">5. 预安装检查</h1>

./runcluvfy.sh stage -pre crsinst -n rnopdb01,rnopdb02 -verbose

保证一切通过即ok。

--solution

tcp_smallest_anon_port

kctune -h -B tcp_smallest_anon_port="9000"

kctune -h -B tcp_largest_anon_port="65500"

kctune -h -B udp_smallest_anon_port="9000"

kctune -h -B udp_largest_anon_port="65500"

有时候在调整内核参数的时候会提示如下的错误：

ERROR: The tunable 'maxswapchunks' is not known.

一般是由于内核参数没有该项造成的，我们可以使用#kctune -u maxswapchunks="16384"来增加，下次启动后就会生效。

kctune -u tcp_smallest_anon_port="9000"

kctune -u tcp_largest_anon_port="65500"

kctune -u udp_smallest_anon_port="9000"

kctune -u udp_largest_anon_port="65500"

<h1 id="6">6. xterm图形化</h1>
在xterm工具中，HP-UX需要选择CDE。

<h1 id="7">7. ASM磁盘组权限</h1>
对于grid和oracle分开安装的Oracle系统，
建议设置ASM磁盘为grid:oinstall,权限设置为660。比如：

chown grid:oinstall disk1001

chown grid:oinstall disk1002

chown grid:oinstall disk1003

...

chmod 660 disk1001

chmod 660 disk1002

chmod 660 disk1003

...

<h1 id="8">8. scan IP修改</h1>
若后续有修改scan IP的需求，
参考文档 ID 972500.1

--1. As grid user stop resources:

$ $GRID_HOME/bin/srvctl stop scan_listener

$ $GRID_HOME/bin/srvctl stop scan

然后修改/etc/hosts文件中SCAN IP Lable对应的IP地址

--2. As root user modify SCAN:

$GRID_HOME/bin/srvctl modify scan -n pay-scan.us.oracle.com

--3. As grid user modify and start resources:

$ $GRID_HOME/bin/srvctl modify scan_listener -u

$ $GRID_HOME/bin/srvctl start scan_listener

--4. To confirm the change

$ $GRID_HOME/bin/srvctl config scan

SCAN name: pay-scan.us.oracle.com, Network: 1/10.4.0.0/255.255.255.0/eth1

SCAN VIP name: scan1, IP: /10.4.0.201/120.0.0.201

SCAN VIP name: scan2, IP: /10.4.0.202/120.0.0.202

SCAN VIP name: scan3, IP: /10.4.0.203/120.0.0.203

$ $GRID_HOME/bin/srvctl config scan_listener

SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521

SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521
