redhat5下安装informix

操作系统：Red Hat Enterprise LinuxServer release 5.5

informix版本：Informix_Ultimate_11.70.UC3_LIN_x86_32_FixPack.tar

把本机IP和hostname写到/etc/hosts里。

1.创建informix用户和组

[root@informix ~]# groupadd -g 1000 informix

[root@informix ~]# useradd -u 1000 -g informix  -m informix

[root@informix ~]# passwd informix

Changing password for user informix.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

 Retype new UNIX password:

 passwd: all authentication tokens updated successfully

[root@informix ~]# id informix

uid=1000(informix) gid=1000(informix) groups=1000(informix)

2.解压文件

[root@informix ~]# mkdir /usr/informix            #数据库安装目录

[root@informix ~]#chown informix:informix /usr/informix

[root@informix ~]#tar xvf  Informix_Ultimate_11.70.UC3_LIN_x86_32_FixPack.tar  -C /usr/informix/insta

3.安装软件：

由于informix默认会把软件安装到/opt/IBM/informix下，要更改目录可以在安装的时候更改也可以安装前更改

安装前设置安装目录：

export INFORMIXDIR=/usr/informix

以下操作以root用户执行：

1) 进入软件目录执行安装程序ids_install

[root@informix insta]# ./ids_install

4.配置

1）设置环境变量

以informix 用户身份登录

[root@informix ~]# su - informix

[informix@informix ~]$vi ids.env       #将以下命令行（总计3行）添加到ids.env 文件：

export INFORMIXDIR=/usr/informix

export INFORMIXSERVER=demo_on

export PATH=$INFORMIXDIR/bin:$PATH

[informix@informix ~]$vi .bash_profile            #在后面加上

INFORMIXDIR=/usr/informix

INFORMIXSERVER=informix

PATH=$PATH:$HOME/bin:$INFORMIXDIR/bin

export PATH INFORMIXDIR INFORMIXSERVER

2）使设置环境生效：

[informix@informix ~]$. ./ids.env

[informix@informix ~]$ source .bash_profile

3)配置onconfig和sqlhosts

cd /$INFORMIXDIR/etc/

cp onconfig.std onconfig

cp sqlhosts.std sqlhosts

vi onconfig

ROOTNAME rootdbs

ROOTPATH /usr/informix/dbspaces/rootdbs

MSGPATH /usr/informix/log/online.log

SERVERNUM 1

DBSERVERNAME informix

SHMBASE 0x10000000L

TAPEDEV /dev/null

DBSPACETEMP     tmpdbs

[informix@informix ~]$mkdir /usr/informix/dbspaces

[informix@informix ~]$mkdir /usr/informix/log

[informix@informix ~]$cd /usr/informix/dbspaces/

[informix@informix ~]$touch rootdbs

[informix@informix ~]$chmod 660 rootdbs

[informix@informix ~]$cd $INFORMIXDIR/tmp

[informix@informix ~]$touch tmpdbs

[informix@informix ~]$chmod 660 tmpdbs

vi sqlhosts      #尾行加

informix  onsoctcp         informix.hans.comsqlexec

[informix@informix ~]#vi /etc/services

sqlexec    9999/tcp

5.启动和关闭数据库

1）启动

[informix@informix ~]$oninit -ivy

启动时报：

shmget: [EEXIST][17]: key 52564801: shared memory already exists

日志信息：

10:50:13  IBM Informix Dynamic Server Started.

10:50:13  shmget: [EEXIST][17]: key 52564801: shared memory already exists

10:50:13  mt_shm_init: can't create resident segment

我的网上搜的解决方法：

NETTYPE          # Configure poll thread(s) for nettype　->暂时不设

#NETTYPE         tlitcp,1,20,NET # Configure poll thread(s) for nettype

NUMCPUVPS       1              # Number of user (cpu) vps　->暂时改为1

BUFFERS         10000           # Maximum number of shared buffers  ->暂时减小10倍为10000

CKPTINTVL       3600               # Check point interval (in sec)   ->这个设置成3600先。

oninit -ivy前请先用ipcs检查下是否有informix用户占用了内存段。

但NUMCPUVPS和BUFFERS 在onconfig文件里没有找到。

同时我又把SERVERNUM 设置为1，但我在另一个安装好的库上看到这个没有设置值

这次启动成功。

2）关闭

[informix@informix ~]$onmode -ky

关闭数据后又重新启动时又报错

网上给的解决方法：

在11.70中加入了FULL_DISK_INIT 这个参数，对当前已经初始化的dbspace进行保护，若是需要初始化dbspace，需要更改这个参数为1 .

 只要初始化成功了，该参数就自动变为0.

以后启动就不需要使用-i 这个命令了，直接使用oninit -vy 就行了。-i 只需要在第一次初始化的时候使用。。

设置成1启动成功。

创建数据库：

1、使用dbaccess进入informix交互环境

2、选择Database，回车

3、选择Create，回车

4、输入数据库名：hans，回车

5、选择Dbspace（表空间）  ，回车

6、选择跟局数据数据库bureaudb一样的表空间，回车

7、选择Log ，回车

8、选择Log，回车（选择日志模式，其他不支持事务）

9、选择Exit，回车

10、选择Create-new-database ，回车。

此时数据库应该已经建立。

查看某个数据库的表空间：

       1、使用dbaccess进入informix交互环境

       2、选择Database，回车

       3、选择Select，回车

       4、选择局数据数据库bureaudb，回车

       5、选择Info，回车

       6、选择dBSpace，回车
