如何安装GBase 8t 测试版

这篇文章将为大家详细讲解有关如何安装GBase 8t 测试版，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

安装GBase 8t 测试版

前期计划：
1,安装Win7x64位系统
2,安装VMware-workstation-full-12.5.4
3,安装CentOS-6.4-x86_64-minimal,网络连接使用桥接模式

ip地址规划：
172.17.6.209 gbase gbase

二，操作系统配置
关闭CentOS启动进度条，替换为详细信息
使用root用户修改 /boot/grub/grub.conf 文件。
找到kernel部分，将"rhgb"去掉，保存即可。其中"rhgb"表示"redhat graphics boot"，就是图形进度条模式。
而"quiet"表示在启动过程中只显示重要启动信息，类似硬件自检之类的消息不会显示，可以有选择地选用。

解决SecureCRT连接linux超时后断开的问题
修改/etc/ssh/sshd_config配置文件 ClientAliveInterval 300（默认为0）
这个参数的是意思是每5分钟，服务器向客户端发一个消息，用于保持连接
service sshd reload 生效

配置内部yum服务器
[root@gbase ~]# yum install traceroute man tcpdump dmidecode vsftpd libaio libgcc libstdc++ compat-libstdc++*-33 ncurses pam openmotif ksh libm.so.6 libncurses.so.5 file wget at sysstat ftp ntp telnet xinetd libXpm perl dbus xhost xauth wqy-zenhei-fonts gedit rsh rsh-server ssh telnet compat-libcap1 bc telnet-server rsync libpam.so.0 libstdc++.so.6 lsof -y

配置下列文件
/etc/selinux/config –关闭selinux
/etc/nsswitch.conf –禁用DNS
/etc/init/control-alt-delete.conf –禁用Control-Alt-Delete
/etc/sysconfig/network –修改主机名
/etc/inittab –修改默认启动级别，mini安装已不需要

1. 数据库用户准备
GBase 8t 使用操作系统用户作为数据库用户，数据库安装前需要创建 informix 组和
informix 用户。informix 用户为 GBase 8t 数据库的管理员用户。
groupadd informix
groupadd bargroup
useradd -g informix -d /home/gbase -p gbase informix
useradd -g bargroup -d /home/tapeback -p gbase tapeback

2. 调整内核参数及用户限制
调整内核参数
echo '
kernel.shmmni=4096
kernel.sem=500 32000 200 256
fs.file-max=65536
net.ipv4.ip_local_port_range=1024 65000' >> /etc/sysctl.conf

修改/etc/profile文件，增加
echo '
export LANG=zh_CN.GB18030
export PATH=$PATH:/usr/sbin
export NOFUZZYCKPT=1
' >>/etc/profile

配置服务
service iptables stop
service ip6tables stop
service iscsi stop
service iscsid stop
chkconfig iptables off
chkconfig ip6tables off
chkconfig iscsi off
chkconfig iscsid off
chkconfig telnet on
chkconfig rsh on
chkconfig vsftpd on
chkconfig atd on

安装jre
[root@gbase installfiles]# chmod +x jre-6u29-linux-x64.bin
[root@gbase installfiles]# ./jre-6u29-linux-x64.bin
[root@gbase installfiles]# mkdir /usr/local/java
[root@gbase installfiles]# mkdir /usr/local/java
[root@gbase installfiles]# mv jre1.6.0_29/ /usr/local/java
[root@gbase installfiles]# cd /usr/local/java/
[root@gbase java]# ln -s jre1.6.0_29/ jre
[root@gbase java]# ln -s /usr/local/java/jre/bin/java /usr/bin/java
[root@gbase java]#

3. 文件系统目录准备(dump目录不创建，放默认/home/gbase/tmp下)
可将 informix 用户 HOME 目录作为 GBase 8t 数据库的安装目录（/home/gbase）。
GBase 8t 安装目录所在的文件系统大小最低为 800MB，建议保留足够大的空间（例如，
10GB 或者以上）。informix 用户需要对安装目录具有读写权限。
准备专门用来存放数据库 dump 文件的目录。创建 lv，并在 lv 上创建文件系统，挂载
的目录名为/home/gbase/dump，用于保存 GBase 8t 数据库断言文件和内存 dump 信息；该
文件系统大小应大于数据库使用的内存总大小。

4. 准备 informix 用户环境变量文件
echo '
INFORMIXDIR=/opt/GBASE/gbase8t
INFORMIXSERVER=ontest
DBDATE=Y4MD0
ONCONFIG=test.cfg
export LANG=en_US.ISO8859-1
export INFORMIXDIR INFORMIXSERVER DBDATE ONCONFIG
export TERMINFO=/home/informix/etc/typetab
export TERMCAP=$INFORMIXDIR/etc/termcap
PATH=$PATH:$HOME/bin:$INFORMIXDIR/bin:.
NSR_DATA_VOLUME_POOL=DBMIData
NSR_LOG_VOLUME_POOL=DBMIData
export NSR_DATA_VOLUME_POOL NSR_LOG_VOLUME_POOL PATH
'>>/home/gbase/.bashrc

四、存储规划
[root@gbase ~]# fdisk -l

Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00036407

Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.

/dev/sda9 3280 4559 10281568+ 83 Linux
[root@gbase ~]#

[root@gbase ~]# cat /etc/udev/rules.d/60-raw.rules
# Enter raw device bindings here.
#
# An example would be:
# ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"
# to bind /dev/raw/raw1 to /dev/sda, or
# ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# to bind /dev/raw/raw2 to the device with major 8, minor 1.
ACTION=="add", KERNEL=="sda5", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sda6", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sda7", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sda8", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sda9", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="raw[1-5]", OWNER="informix", GROUP="informix", MODE="660"
[root@gbase ~]#

建立所需要的文件夹
mkdir /informix.links
ln -s /dev/raw/raw1 /informix.links/rootdbs
ln -s /dev/raw/raw2 /informix.links/plogdbs
ln -s /dev/raw/raw3 /informix.links/llogdbs
ln -s /dev/raw/raw4 /informix.links/tempdbs
ln -s /dev/raw/raw5 /informix.links/datadbs

根据实际情况配置/etc/services，/etc/hosts,/home/informix/.rhosts
echo '
#Informix Port
shop 8888/tcp
' >>/etc/services

echo '
172.17.6.209 GBase
' >>/etc/hosts

重启安装GBase

5，加空间
空间管理：onmonitor
onspaces -c -d plogdbs -p /informix.links/plogdbs -o 0 -s 1024000
onspaces -c -d llogdbs -p /informix.links/llogdbs -o 0 -s 1024000
onspaces -c -d tempdbs -t -p /informix.links/tempdbs -o 0 -s 1024000
onspaces -c -d datadbs -p /informix.links/datadbs -o 0 -s 10240000

使用onparams 更改物理日志位置和大小
onparams -p -s 1023000 -d plogdbs -y


逻辑日志文件位置及个数调整，先删除3个，再建立3个，接着移动一下检查点位置再删除3个。
onmode -l
onmode -l
onmode -l
onmode -c

onparams -d -l 1 -y
onparams -d -l 2 -y
onparams -d -l 3 -y

onparams -a -d llogdbs -s 10000
onparams -a -d llogdbs -s 10000
onparams -a -d llogdbs -s 10000

onmode -l
onmode -l
onmode -l
onmode -c

onparams -d -l 4 -y
onparams -d -l 5 -y
onparams -d -l 6 -y

最后要留下三个日志并且必须是从1开始的，否则在增加日志数时，number号会乱掉的：

address number flags uniqid begin size used %used
5b5d8f98 1 U—C-L 12 3:25053 5000 14 0.28

# Physical Log Configuration Parameters
###################################################################
# PHYSFILE – The size, in KB, of the physical log on disk.
# If RTO_SERVER_RESTART is enabled, the
# suggested formula for the size of PHSYFILE
# (up to about 1 GB) is:
# PHYSFILE = Size of BUFFERS * 1.1
# PLOG_OVERFLOW_PATH – The directory for extra physical log files
# if the physical log overflows during recovery

###################################################################
# Logical Log Configuration Parameters
###################################################################
# LOGFILES – The number of logical log files
# LOGSIZE – The size of each logical log, in KB
# DYNAMIC_LOGS – The type of dynamic log allocation.
# Acceptable values are:
# 2 Automatic. Informix adds a new logical log to the
# root dbspace when necessary.
# 1 Manual. Informix notifies the DBA to add new logical
# logs when necessary.
# 0 Disabled

# Long Transaction Configuration Parameters
###################################################################
# If Informix cannot roll back a long transaction, the server hangs
# until more disk space is available.
#
# LTXHWM – The percentage of the logical logs that can be
# filled before a transaction is determined to be a
# long transaction and is rolled back
# LTXEHWM – The percentage of the logical logs that have been
# filled before the server suspends all other
# transactions so that the long transaction being
# rolled back has exclusive use of the logs
#
# When dynamic logging is on, you can set higher values for
# LTXHWM and LTXEHWM because the server can add new logical logs
# during long transaction rollback. Set lower values to limit the
# number of new logical logs added.
#
# If dynamic logging is off, set LTXHWM and LTXEHWM to
# lower values, such as 50 and 60 or lower, to prevent long
# transaction rollback from hanging the server due to lack of
# logical log space.
#
# When using Enterprise Replication, set LTXEHWM to at least 30%
# higher than LTXHWM to minimize log overruns.

# Configuration Parameters
###################################################################
# DRAUTO – Controls automatic failover for HDR systems.
# If the connection manager is providing failover,
# then the only value which should be used is '3'.
# Additionally, if the connection manager is being
# used to provide failover services, then a manual
# failover (onmode -d standard or onmode -d make primary)
# should not be performed without first
# bringing down the connection managers.
#
# Acceptable values are:
# 0 No automatic failover
# 1 Retain server type
# 2 Reverse server type
# 3 Connection Manager Arbitrator controls
# server type
# DRINTERVAL – The maximum interval, in seconds, between HDR
# buffer flushes. Valid for HDR only.
# If set to zero then DRINTERVAL is not used and
# HDR_TXN_SCOPE will be used instead.
# HDR_TXN_SCOPE – Defines transactional synchronization in the
# HDR primary when DRINTERVAL is turned off
# The default is NEAR_SYNC.
# Valid values are
# ASYNC – Commits are not synced
# NEAR_SYNC – The committed transaction has been
# sent to the HDR secondary but not yet
# applied.

# network-based connection type. Valid for HDR,
# SDS, and RSS.
# HA_FOC_ORDER – The cluster failover rules.
# Values are MANUAL or some order of SDS,HDR,RSS.
# Individual server names are not allowed. The default
# of SDS,HDR,RSS is the preferred failover order.
# If you do not have one of the secondary types
# then that type is skipped. If for any reason none
# of the server types are available, then a manual failover
# will be performed.

# Buffer pool and LRU Configuration Parameters
###################################################################
# BUFFERPOOL – Specifies the default values for buffers and LRU
# queues in each buffer pool. Each page size used
# by a dbspace has a buffer pool and needs a
# BUFFERPOOL entry. The onconfig.std file contains
# two initial entries: a default entry from which
# to base new page size entries on, and an entry
# for the operating system default page size.
# When you add a dbspace with a different page size,
# IDS adds a BUFFERPOOL entry to the onconfig file
# with values that are the same as the default
# BUFFERPOOL entry, except that the default
# keyword is replaced by size=Nk, where N is the
# new page size. With interval checkpoints, these
# values can now be set higher than in previous
# versions of IDS in an OLTP environment.
