Linux平台安装Informix Dyanmic Server 10.00.UC4

 

第一步，安装必须的包（RH AS3）

 gcc and c++ compiler 3.2.3

 

        compat-gcc-7.3
        compat-gcc-c++-7.3
        compat-libstdc++-7.3
        glibc-devel-2.3.2
        libaio-0.3.96
        libgcc-3.2.3
        libstdc++-3.2.3
        ncurses-5.3
        openmotif-2.2.3
        pam-0.75
        XFree86-libs-4.3.0

 

第二步，搭建安装环境

1.建立informix用户组和用户

以root身份登陆，然后:

groupadd -g 3000  informix

useradd -u 3000 -g 3000 informix -d /home/informix -m informix

2.修改环境变量

#su informix
#cd
#ls -a
#vi .bash_profile

修改为如下：

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

#PATH=$PATH:$HOME/bin
INFORMIXDIR=/opt/informix   //informix的安装路径
export INFORMIXDIR
INFORMIXSERVER=informix  //informix的服务器名
export INFORMIXSERVER
ONCONFIG=onconfig.informix //informix的配置文件名
export ONCONFIG
LD_LIBRARY_PATH=/opt/informix   //informix的lib库路径
export LD_LIBRARY_PATH

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

export PATH
unset USERNAME

 

保存退出之后，修改权限

#chmod 755 .bash_profile

使以上设定生效

#./.bash_profile

 

第三步，上传安装文件

 

1.用SecureFX连接虚拟机，将安装文件IDS.10.00.UC4.Linux.tar上传到 /home/informix 目录下
2.以root/informix身份登陆系统，到/home/informix，解压安装文件

$tar xvf IDS.10.00.UC4.Linux.tar

第四步，开始安装

以root身份登陆(我看过网上的很多文档，都是以informix用户登陆来安装，但我以informix身份登陆进行安装的时候，系统提示我需要以root身份来安装）

#cd /home/informix/SERVER

执行安装脚本

#./installserver

Please select one of these options [3]   //回车

Beginning installation...

接下来的安装过程要做一些选择，都比较简单，基本上按照默认的就可以,一路回车，直到安装完成，得到如下提示：
Please read the information below.

Set required environment variables
        Set $INFORMIXDIR to the directory where the IDS server is installed.
        Set $PATH to include $INFORMIXDIR/bin
        Set $INFORMIXSERVER to the name of the database server
        Set $ONCONFIG to the name of the active onconfig configuration file.
        If using a sqlhosts file other than $INFORMIXDIR/etc/sqlhosts
                Set $INFORMIXSQLHOSTS
        If using a locale/language other than the default
                Set $CLIENT_LOCALE
                Set $DB_LOCALE
                Set $SERVER_LOCALE
                Set $DBLANG
Prepare connectivity files
        sqlhosts
        /etc/hosts
        /etc/services
Prepare configuration file
        Set DBSERVERNAME
        Set SERVERNUM
        Set ROOTNAME

Press ENTER to read the text [Type q to quit]

        Set ROOTPATH
        Set ROOTSIZE   
Initialize database server
        As informix or root, run oninit
        If initializing a new server for the FIRST time, run oninit -i
This will overwrite any existing data, so use caution on an exis
ting setup

 

我们可以根据提示来具体的配置informix服务器。

 

第五步，配置informix

 

1. 在informix安装目录建立data目录，然后touch一个空文件作为数据库的默认设备，并且修改空文件的权限为660

$ mkdir data
$ cd data
$ touch datadbs.dat
$ chmod 660 datadbs.dat //一定要执行这一步，否则在后续的启动过程中会出错

 

2.配置onconfig文件

默认的配置文件在 /opt/informix/etc/onconfig.std

我们复制一份，并且改其后缀名为之前设定的informix服务器名，此处为 informix

$cd /opt/informix/etc/onconfig.std
$cp onconfig.std  onconfig.informix
$vim onconfig.informix

打开之后，我们需要修改的地方有以下几项：

# Root Dbspace Configuration

ROOTNAME       rootdbs   # Root dbspace name       //rootdbs换成datadbs
ROOTPATH      /dev/online_root # Path for device containing root dbspace 
              // 把/dev/online_root换成 /opt/informix/data/datadbs.dat
ROOTOFFSET      0               # Offset of root dbspace into device (Kbytes)
ROOTSIZE        30000           # Size of root dbspace (Kbytes)

# Physical Log Configuration

PHYSDBS  rootdbs #            //rootdbs换成 datadbs
PHYSFILE        2000            # Physical log file size (Kbytes)

# System Archive Tape Device

TAPEDEV         /dev/tapedev    # Tape device path      //tapedev换成null
TAPEBLK         32              # Tape block size (Kbytes)
TAPESIZE        10240           # Maximum amount of data to put on tape (Kbytes)

# Log Archive Tape Device

LTAPEDEV       /dev/tapedev    # Log tape device path   //tapedev换成null
LTAPEBLK        32              # Log tape block size (Kbytes)
LTAPESIZE       10240           # Max amount of data to put on log tape (Kbytes)

# System Configuration

DBSERVERNAME                    # Name of default database server  
//数据库服务器名称，这里设置成和环境变量里的一样 informix

最后，将这个文件中所有的/usr/informix换成 /opt/informix (informix的安装目录）

可以使用shell脚本命令来完成，在命令行运行

:%s/\/usr\/informix/\/opt\/informix

 

3.配置系统服务（需要root权限）

su到root用户
#vim /etc/services

在最后一行，添加如下内容：

informix_services 8888/tcp          #informix server services

 

4.配置sqlhosts文件（切换回informix用户）

安装完成后，有个默认的sqlhosts.std文件，在/opt/informix/etc 目录下

$cd /opt/informix/etc
$cp sqlhosts.std sqlhosts
$vim sqlhosts

修改为如下内容：

informix        onipcshm        rouse           informix_services
informix        onsoctcp        rouse           informix_services

informix：是数据库服务器名，和环境变量中的一样
onipcshm/onsoctcp：使用的协议名称，连接数据库的两种方式
rouse：主机名，和/etc/hosts里的一样
informix_services：服务名，和/etc/services中的一样

 

5.启动informix

修改完所有配置文件之后，重启系统，然后可以尝试启动informix服务器

$ oninit -ivy  //第一次启动的时候需加 -ivy参数，以后正常启动时直接 oninit

说明执行成功，如果中间出现error或者warning，我们可以man一下日志文件（/opt/informix/online.log)，来看看是什么问题。

接下来，到/opt/informix/data 查看一下datadbs.dat文件的大小，如果不为0，那么说明数据库创建成功。

$ onstat -i
IBM Informix Dynamic Server Version 10.00.UC4     -- On-Line -- Up 00:06:29 -- 28552 Kbytes
onstat>

说明数据库状态正常，退出 onstat 输入 q 就可以
