• ibm.csdk.4.50.FC4W1.LNX.tar 可以安裝在informix的叢集上，也可以安裝在非informix的機器上

1.1、下載

[root@test ~]# wget https://iwm.dhe.ibm.com/sdfdl/2v2/regs2/mstadm/informix/Xa.2/Xb.YBTN_DlRQlu3TFy95gEcGB8pOJCWo7GBhurOSj1sL-k/Xc.ibm.csdk.4.50.FC4W1.LNX.tar/Xd./Xf.lPr.D1vk/Xg.11016302/Xi.ifxdl/XY.regsrvs/XZ.td5HG7ZumKTZ6q2Dl9Ex3r-TSQMmwc25/ibm.csdk.4.50.FC4W1.LNX.tar
 

1.2、解壓安裝

[root@test ~]# mkdir informix
[root@test ~]# tar -xvf ibm.csdk.4.50.FC4W1.LNX.tar -C informix/
[root@test ~]# cd informix
[root@test informix]# ls
csdk.properties  doc  installclientsdk  README_csdk.txt

2、安裝unixODBC-devel

[root@test ~]# yum install -y unixODBC-devel unixODBC
​

2.1、驗證安裝

[root@test ~]# odbcinst -j
unixODBC 2.3.1
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /etc/odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8
 

3、配置ODBC驅動

[root@test ~]# vim /etc/odbcinst.ini
# 新增以下模組
​
[INFORMIX]
Description   = ODBC for IBM Informix
Driver     = /opt/IBM/Informix_Client-SDK/lib/cli/iclit09b.so
Setup      = /opt/IBM/Informix_Client-SDK/lib/cli/iclis09b.so
APILevel=1
ConnectFunctions=YYY
DriverODBCVer=04.10
FileUsage=1
SQLLevel=1
smProcessPerConnect=Y
​

• Driver 指定自己檔案的安裝路徑

• Setup 指定自己檔案的安裝路徑

4、ODBC資料來源配置

# 建立並編輯odbc.ini
[root@test ~]# vim /etc/odbc.ini
​
[sysadmin]
Driver=INFORMIX
Description=INFORMIX
Database=sysadmin
LogonID=informix
pwd=123456
Server=tramsserver
CLIENT_LOCALE=en_us.819
DB_LOCALE=en_us.819
TRANSLATIONDLL=/opt/IBM/Informix_Client-SDK/lib/esql/igo4a304.so
​

配置引數說明：

• [sysadmin] ：中括號裡面需要指定informix資料庫名稱

• Driver ：對應odbcinst.ini檔案中 [ ] 裡的名稱

• Database ：資料庫名稱，對應 [ ] 裡的名稱

• LogonID：資料庫使用者名稱

• pwd：資料庫密碼

• Server：資料庫的例項名

• TRANSLATIONDLL：對應檔案的安裝路徑

5、配置sqlhosts檔案

• 在Informix_Client-SDK的安裝目錄的etc下編輯sqlhosts檔案

[root@test ~]# cd /opt/IBM/Informix_Client-SDK/etc
[root@test ~]# vim sqlhosts
tramsserver onsoctcp 192.168.30.91 8888
​

sqlhosts檔案說明：

• 可以直接將informix資料庫裡的sqlhosts檔案複製過來

• 第一列：資料庫的例項名

• 第二列：協議

• 第三列：informix資料庫IP

• 第四列：informix資料庫埠

6、環境變數配置

[root@test ~]# vim ~/.bash_profile
# 新增下面內容
​
INFORMIXDIR=/opt/IBM/Informix_Client-SDK
INFORMIXSQLHOSTS=/opt/IBM/Informix_Client-SDK/etc/sqlhosts
ODBCINI=/etc/odbc.ini
LD_LIBRARY_PATH=${INFORMIXDIR}/lib:${INFORMIXDIR}/lib/cli:${INFORMIXDIR}/lib/esql
export INFORMIXDIR INFORMIXSQLHOSTS ODBCINI LD_LIBRARY_PATH
​
[root@test ~]# source ~/.bash_profile
​
# 登入測試
[root@ansible-test etc]# isql sysadmin
